hello jashton34, did you write your question from the system affected? because its useragent (the information the browser sends to websites to identify its version and system where it's running) says it's on Mac OS X 10.5...

Thanks madperson, Yes, I did write my question from the same system, but I'm running 10.6, I promise. The system came with 10.5 installed but I upgraded to 10.6 a while ago. Here's a copy and past from my system profiler, and I've attached a screen shot of my About This Mac.

System Software Overview:

 System Version:	Mac OS X 10.6.8 (10K549)
 Kernel Version:	Darwin 10.8.0
 Boot Volume:	Macintosh HD
 Boot Mode:	Normal
 Computer Name:	Jeff Ashton's Computer (2)
 User Name:	Jeff Ashton (jeffashton)
 Secure Virtual Memory:	Not Enabled
 64-bit Kernel and Extensions:	No
 Time since boot:	15 days 14 minutes

The useragent is clearly a liar, do you know if there's any way to fix that?

ok, when i look closer it seems like your useragent is overwritten by some sort of toolbar or adware. please refer to this article in order to reset the user-agent settings in firefox, then it should work: How to reset the default user agent on Firefox

That fixed it. You're a Rockstar, madperson, thanks!

Hello! I have the same problem, I tryed to follow the steps to fix it myself but I couldnt reset 3 elements that where showew in the search, it was not possible, I would really apreciate your help!

Thank you

hello viturbo, without more information its difficult to know what might be going wrong...

when the preferences concerning the user-agent in about:config were not shown in bold that means they were already set to their default & can't be reset. please go to help > troubleshooting information, copy the whole contents of this page & paste them here into a forum reply, this might give us some further clues. thank you

& what kind of user-agent information is shown on that page? for jashton34, the question owner, it looked like this for example: Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.5; en-US; rv:1.9.2.10) Gecko/20100914 Firefox/3.6.10 FBSMTWB

Also trying to install google chrome is not possible because that my system doesnt match...but before I could do it... if this helps too

what OS are you on? mozilla & google don't support systems below os x 10.6 or on the powerpc architecture in their modern browser products anylonger...

Oh... I have 10.5.8 what can I do then¿?

is your device intel based? in this case you could upgrade to 10.6 and the browsers should still work - for more information please see Firefox no longer works with Mac OS X 10.5, http://store.apple.com/us/product/MC573Z/A/mac-os-x-106-snow-leopard or contact apple's support.

Yes, its intel based. but how can I upgrade to 10.6?

You can call 1-800-MY-APPLE and order a dvd for $20 if you are in USA unless you can get one in Apple stores by chance.
