My computer is totally non functional since istalling the lastest version of firefox

more options

My computer freezes, crashes, does not recognize websites I have always used and is in general almost totally non functional, besides which I have no sound at all. I do not think all these problems are due to firefox but I figured I would start here.

I am a computer novice but I use my computer daily and am so frustrated I am considering buying a new one. However I do not want to do that until I utilize this one to its full potential. Please help!

Create a new profile as a test to check if your current profile is causing the problems.

See "Basic Troubleshooting: Make a new profile":

There may be extensions and plugins installed by default in a new profile, so check that in "Tools > Add-ons > Extensions & Plugins" in case there are still problems.

If that new profile works then you can transfer some files from the old profile to that new profile, but be careful not to copy corrupted files.

If you have submitted Breakpad crash reports then post the IDs of one or more Breakpad crash reports (bp-xxxxxxxx-xxxxxxxxx-xxxx-xxxxxxxxxxxx). You can find the IDs of the submitted crash reports on the about:crashes page. You can open the about:crashes page via the location bar, like you open a website.
