I have updated Firefox and it shows that I am running the latest version 52.1.2 esr 32 bit. Several sites say that I need to update Fire fox, even after updating it still says I need to update Firefox. What do I need to do to fix this problem? Thank you for your help.

Chosen solution

My guess is, the latest Firefox version is at 53.0.3. The ESR version is based on 52, so some wires are getting crossed there.

Is your user agent intact? After checking , its seems not so. Your current user agent (was submitted alongside your question) is User Agent: Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.2.25) Gecko/20111212 YFF35 Firefox/3.6.25 ( .NET CLR 3.5.30729; .NET4.0C) FBSMTWB

Notice the Firefox 3.6.25 line. That's not good.

Go into about:config via Firefox's address bar and click the warning saying you'll be careful. Search in the filter box for useragent.override and if there is an entry, delete it (Right click --> Reset)

I also see a user.js file in your Firefox profile folder. Note that user.js is a manually created file (or unintentionally added during your user agent switch). If you did not make this file, please delete it before trying to change about:config prefs.


On another note, did you download the Yahoo optimized version of Firefox as that has the toolbar and such and may be causing issues.
