User Agent says it's MSIE ?!

Asked by Adilson Mohr

I everybody !

It's been a while since I am fighting with Yahoo Mail to work well with Shiretoko... I always thought it was about that Shiretoko/Firefox thing that a lot of people are complaining about. I've tried a lot of modifications in the about:config user agent and in the Firefox files, with no sucess - but today I found something new.

Browsing around, I saw that my user agent is been discoreved as :

HTTP USER AGENT header Mozilla/4.0 (compatible; MSIE 5.5; Windows 98)
Browser branch name IE 5.5
Browser name IE
Browser version 5.5
Platform Win98
Operation System Windows 98
Browser full name MSIE 5.5

But that is not correct ! The Help -> About Firefox says :
Mozilla/5.0 (X11; U; Linux i686; en-US; rv: Gecko/20100106 Ubuntu/9.04 (jaunty) Firefox/3.5.7

The about:config is like default:
general.useragent.extra.firefox Firefox/3.5.7
general.useragent.locale en-US U
general.useragent.vendor Ubuntu
general.useragent.vendorComment jaunty
general.useragent.vendorSub 9.04

I didn't want to open a bug, as I didn't find anyone else with this problem - and I have the same problem with Firefox 3.0... Looks like something with my Ubuntu, instead of with Firefox/Shiretoko... as far as I remember, it started when I installed Jaunty...

Does anyone knows what can it be ?!

Well, the problem is with ntlmaps... I don't know why, but when I disabled it, the UA started to look ok :

HTTP USER AGENT header Mozilla/5.0 (X11; U; Linux i686; en-US; rv: Gecko/20100106 Ubuntu/9.04 (jaunty) Firefox/3.5.7.

Please, add a comment if you know why this happens...

Anyway, that didn't made Yahoo work correctly :-/

(thanks to programad from, to point the direction -

Well, now Yahoo Mail is working - I didn't see that the error message has changed to something like "not tested in your OS, take your chances". Hit ok and it's working as usual :)
