Websites (LinkedIn, Google Drive, and others) think I'm using an older firefox, but I'm using Firefox 43. What causes this?

more options

Many websites display a message that I'm using an older unsupported Firefox version, and require an upgrade. But I'm running Firefox 43 (just installed recently). Need to find out what is causing this. Google Drive does not operate and redirects me to a browser upgrade screen. I have multiple versions of Firefox on my PC. I'm running Windows XP Home, Service Pack 3, 32-bit firefox. What do these websites look at in the request? Perhaps it is something in the request headers..

Any help is greatly appreciated..

Joe

Hi Joe, that's a good guess. Please try the following article to see whether this setting is the root of the problem: How to reset the default user agent on Firefox.

If that isn't it, one of your extensions might be modifying the user agent string in your requests. You didn't share that data with the forum, so let's come back to that.

The browser useragent displayed when you posted this thread is Mozilla/5.0 (Windows NT 6.1; WOW64; rv:27.0) Gecko/20100101 Firefox/27.0

It looks you are using a useragent that shows Windows 7 also (NT 6.1)

Hello James,

I posted from my workplace which runs Firefox 27.0.1 (an old firefox), and I am running Windows 7 Enterprise. The problem is from my home PC, an old Dell running Windows XP Home Service Pack 3. I am running Firefox 43 (32 bit) from home..

I'll try to get the useragent later tonight..

The problem is solved. The about:config showed a setting general.useragent.overide referring to Firefox 16.. I just reset the variable and now it sends Firefox 43..
