This page was getting big - we're talking big. So we split the mobile things onto a separate page.
We started these pages with four strings because we had never seen a comprehensive list anywhere. Nominally RFC 1945 and RFC 2068 define them (get RFCs) but only as an afterthought (the RFCs define HTTP 1.0 and 1.1). Browser IDs, more correctly User Agent IDs, appear, among other places, as the environmental variable HTTP_USER_AGENT in Apache. You need this information to make the fewest checks possible for the browser environment or how to optimise the display or ... to know who and what is crawling around your site. And if you want to check your browser string with our page or one from Julian Grammer will also give your IP address.
New Stuff: All seems pretty quiet on the Firefox front recently - but a new MSIE 8 Beta 1 - with, let me guess, improved security. Seems like only yesterday MSIE Beta 7 was issued. Some (read one) answers to mysteries. We always set out to confuse - it's our main objective in life - we have filed the Playstation strings under Sony - to prove we are really, really smart and know who manufactures it.
As always - especially if you are feeling a super-sleuth moment coming on - have look at the mystery strings and strings from server logs to add to the total of mankind's knowledge.
For browser historians. We thought that Mosaic was the original browser. As usual we were wrong. James Butler took the time to drop us an email - thanks:
Before there was NSCA's Mosaic there were several other browsers capable of interpreting HTML, including Erwise and Viola, both of which I used before the Andreeson project issued any software. Although primarily for viewing SGML, both of those browsers did a pretty good job of parsing the very basic HTML commands that Mr. Berners-Lee published as he developed his SGML subset (HTML).
We are discontinuing the crawler, spiders and robots section - there is much better coverage at this site which is the home of robots.txt which is, as you all know, the file that tells well behaved crawlers to 'keep out' of your dirty linen.
If your browser string is NOT here please take a moment and click here then mail us the result (if you are using an exotic browser send us the URL of where to get it). We are now crediting the supplier of each string or answer individually as a homage to all those folks who take the time as thousands of you have done over the years. Many thanks for helping ourselves. We have added some info about changing UA strings which unless you have to do it is, we think, a Very Bad Thing™.

Phoenix is dead - long live Firebird. Firebird is dead - long live Firefox. Firebird/Phoenix has morph'd into Firefox. The Mozilla roadmap shows Firefox as the browser for the next generation of Mozilla. Essentially (if we can paraphrase a very big page) the mozilla design team are saying that they will develop a set of components (browser, mail client, editor (composer) and others) which will work well together but will have their own development priorities and timeframes, rather than the current monolithic Mozilla structure. The historic Phoenix and Firebird strings are still on the main page 'cos we like to remind 'em of their humble beginnings. Note: For Firefox 3 and perhaps after, Minefield will remain the development version and always have 'pre' in the string, whereas GranParadiso is the release leg and will not have 'pre' in the string - so there you go.
Don't forget the Mozilla SeaMonkey project about which which J. Reynolds writes:
The SeaMonkey project is a community effort to deliver production-quality releases of code derived from the application formerly known as "Mozilla Application Suite". Whereas the main focus of the Mozilla Foundation is on Mozilla Firefox and Mozilla Thunderbird, our group of dedicated volunteers works to ensure that you can have "everything but the kitchen sink" and have it stable enough for corporate use.
Note: The seamonkey strings are under Mozilla.
Nathan Lineback supplied this reference to a bunch of screen shots showing the OS's to which Firefox (1.5 mostly) has been ported.
This represents the current and major historic release versions of the strings - well in our unbalanced judgment. We maintain a separate page with a complete list of Firefox strings that we have ever found or received (including some really bizarre stuff) - includes those on this page.

A Mac only browser with some very nice features. You get to buy this one for $29. Tough business model with Safari and Camino now available. Beta versions are free. However this is the only currently being developed browser that runs across the whole MAC range - if you need a single browser interface that spans from the ancient 680x0 Macs to the whizbang OS X world - there is only one game in town - iCab.

Browser supplied with JBuilder. Since its all Java based it may be a development of the origonal HotJava browser which I thought was great (eh!) for its time.
ICE Browser/5.05 (Java 1.4.0; Windows 2000 5.0 x86)

Our browser of choice on windows. No contest.

It's way too late to regain the past glory days but a high function, standards compliant, browser. The new Version 9 is called Navigator again which as Deyan Mavrov reminds us is the first time they used the name since NS4.x (now was that a release). Since version 8 they have been using the firefox base with their own stuff added and very slick graphic design (IOHO). Previous versions use the full Mozilla build (now seamonkey). Wonder who uses it - we guess it's just folks who have always used Netscape left. End of an era. Sigh. Wonder what they are going to do for a mail client? (Thunderbird package?)
This represents the current and major historic release versions of the strings - well, in our unbalanced judgment. We maintain a separate page with a complete list of Netscape strings that we have ever found or received (including some really bizarre stuff) - includes those on this page.

OS X browser now in Release 2.0 (with V 3 in Beta) for you MAC users - and now available for the iPhone and iPod as well as more earth-bound devices. Following explanation of browser geneology from Robert Johnson "Safari uses, and Apple helps develop KHTML (which is what Konqueror embeds). KHTML is in WebCore, which is part of AppleWebKit. AppleWebKit is available to any app on the Mac. OmniWeb abandoned their own rendering engine for AppleWebKit with version 4.5.". So there you go. Apparently the choice of KHTML instead of Gecko was a wee bit contentious. Safari apparently now runs on Windows as well as OS X.

Explanation: A web browser for DOS (honest) which you can obtain here. From Ryan Jones - thanks.
This section shows strings from a number of plug-ins or proxy services whose job in life (they have decided) is to help (maybe) the user as they meander throughout the 'net. We are going to try and build a list with links to the plug-in site and - with your help - categorise them both as to how they get installed - e.g. willing user or stealth and wheter they are benign or nasty. In may cases we just show the additional string that will result rather than a full browser string - we're not gonna install nasty things just for your information now are we - well not willingly we're not!
..FunWebSearch...
Explanation: MyWebSearch (or FunWebProducts enhanced browser - not classified as sypware or adware. To remove it - go here. Info from Chris Gulutz - thanks.

ESB{A8417D9D-5087-4807-9D73-9E09290256CD})
String from Remco de Vijlder. Axel Kollmorgen and Eugene Sadhu suggest that it is most likely EasySearchBar (ESB - geddit). Jim Rofkar and Eugene Sadhu both add another possibility - Easy Start Bar for laptops. Thanks guys.

vobsub
Explanation: Contributed by Jan Praestkjaer. A CD ripping plug-in. More information may obtained here.
Explanation: Contributed by John Bridges. 'DigExt' can appear in a MSIE browser string and is potentially pretty nasty. If you ask for content to be available off-line in certain versions of MSIE (we saw it on 5.0 and 4.x) then MSIE will grab a lot of stuff from the sites you visit and slave it in its temporary internet files. Pretty unpleasant stuff since it chews up your and the sites bandwidth. Sounds like a nice option but MS don't tell you the consequences. Now if I just knew where the option was I'd disable it but since I just upgraded to MSIE 6.0 (cos my 5.0 kept crashing after I refused an automatic update - any connection!! Oh and by the way in case you think we are prejudiced we also upgraded to NS6) I can't find any of this stuff and my browser string doesn't show 'DigExt' anymore - is this another mystery! If you are interested to get more info on the pernicious 'DigExt' John provided this link.
This may have morphed in the first string shown under the MSIE list - it contains 'MSIECrawler' - thanks to Adam Hauner.
These strings were sent to us from various logs. If you think you know what they are drop us an email and we'll add an explanation. Lines beginning with # indicate our comments and explanations:

holmes/3.10.1 (OnetSzukaj/5.0; +http://szukaj.onet.pl)
Submitted by David Ross (thanks). Answer from Michal Malek. Apparently it is a polish search engine crawler from OnetSzukaj. Many thanks. And he didn't need a cell phone.
Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; .NET CLR 1.1.4322; IEMB3; IEMB3)
Submitted by Ineke K (thanks). The most plausible explanation is IE Mobile Browser but with a 7.0 version?
Bookdog/3.11.4
This one was submitted and answered by David Ross (thanks). Its BookDog (which apparently replaces Safari Sniffer) and can organize/validate bookmarks for Safari, Camino and Firefox on the Mac. It replaces the normal User-Agent string rather that adds to it which is normal mode for BHO and Plugins - pretty strange even if not a true mystery.
Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; BT [build 60A]; .NET CLR 1.1.4322)
Any ideas about the BT [build 60A] string? String from John Dobson.
Alexander Twigg thinks this is the British Telecom Yahoo! browser based on MSIE 6 - and who are we to dispute that - many thanks Alexander.

KDDI-CA31 UP.Browser/6.2.0.7.3.129 (GUI) MMP/2.0
We suspected it was some kind of Japanese mobile device (IP tracked to Internet Multifeed Co. of Japan). String from David E. Ross. Yeah it's a DoCoMo device. Answer from karawapo who also supplied a huge list of DoCoMo devices.
Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 1.1.4322; Secure IE 3.3.1286)
String from Lewis Kapell. Possible answer also from Lewis is Secure IE (surprise, surprise).
Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; i-NavFourF; .NET CLR 1.1.4322)
String from maffiou. Possible answer also from maffiou is the i-van system from Verisign, Inc. which allows International names in URLs (including DNS). More possibiliies here. Confirmed by Andreas Städing.
Mozilla/4.0 (compatible; MSIE 5.5; Windows NT 5.0; TIMET-0904; TIMET-040122)

Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0; AT&T CSM7.0; .NET CLR 1.0.3705; .NET CLR 1.1.4322; Hotbar 4.6.1)
String from Brantley Harris. The hotbar is clearly our good friends hotbar who monitor your traffic. You can remove it here. But the CMS... Turns out it's AT&T Worldnet Customer Support Manager v7.0. Update from Don Beele - thanks.
Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; iebar)
String from Willem van Nunen. Its, suprisingly, iebar now why didn't we think about that ('cos we're stupid thats why). Answer from Chip Downs - thanks.
Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:0.9.4.2) Gecko/20021112 CS 2000 7.0/7.0
String from Willem van Nunen. Answer from Richard Aspden it is "the CompuServe 2000 application, which had Gecko built-in. AOL was going to do the same with it's own native software (AOL owning CS), but decided to use IE in the end anyway.". Many thanks.

String from Remco de Vijlder. Axel Kollmorgen, Eugene Sadhu and Jim Rofkar all made suggestions - we moved this one to the BHO section with the best links we can find. Oracle's Fusion Middleware Enterprise Service Bus?
Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; DIL0001021)
String from John Dobson. Answer: Seems is Demon Internet Limited a big UK ISP who customize MSIE. From Lee Harvey Osmond - thanks - who also wants to know what 'YPC' means in a string.
Mozilla/4.0+(compatible;+MSIE+5.5;+Windows+NT+4.0;+H010818)
String from Jim Rofkar. Possible Answer: From Eugene Sadhu "Interestingly this string "H010818" is found in the registry of WinME machines and may have some correlation to the WindowsUpdate App. Perhaps a browser used after visiting the WindowsUpdate site will send this string to other machines on the same session. HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings\User Agent\Post Platform\H010818" Many thanks.

{8E13D179-78A2-4C06-9BFC-EA5BF2EE1750})
String from Jim Rofkar - followed by the answer from Jim also. These may indicate the browser has a BHO (Browser Helper Object) software installed (perhaps unwittingly) from either LOP foistware (site link appears broken) or WurlMedia. This site seems to keep a reasonably up-to-date list of nasty things. If you think you have got some nasty stuff on your browser just type 'hijack' into a google search and follow the most promising links.
...SURF...
Anyone know what application the word SURF in a browser string comes from? String from Erik Nelson. Tyler Bannister writes" One of our students is having a problem with her browser pre-fetching every page she reads in Internet Explorer. The problem doesn't occur in Netscape, thus it seems likely that "SURF" is some type of browser help object for IE and probably malware" - thanks - anyone got more on this one?
Mozilla/4.01 (Compatible; Acorn Phoenix 2.08 [intermediate]; RISC OS 4.39) Acorn-HTTP/0.84
Anyone know what the browser being used is? String from Erik ?. Updated answer from Chris Bazley. Apparently the original Acorn Browse in a development version morphed into Phoenix (not to be confused with the pre firebird pre firefox mozilla browser!) on the ACORN RISC OS. For all you ACORN fans however seems there may be a Firefox port called Rozilla.
mozilla/4.0 (compatible; msie 6.0; windows 98; ypc 3.0.2; yplus 4.4.01d)
Anyone know what the ypc and yplus is? String from Bruce Preston.
Answer: It's Yahoo Parental Controls which seems to be available to you if you sign-up with Yahoo. Answer from John Pye - thanks.
Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; FREE; .NET CLR 1.1.4322)
Anyone know what the FREE is? String from Jean Christophe Olivain. Axel Kollmorgen writes "seems to be a customized version of IE made by free.fr or a related company. all the "FREE" agents in my logs are from france and their ip's related somehow with free.fr". Thanks Axel. Confirmation from Symon Rottem who says that the isp free provides an installation CD with a customised version of MSIE. This one is now dead - maybe we should move to the MSIE strings.
Mozilla/4.5 RPT-HTTPClient/0.3-2
We suspect this may be an e-mail extractor
