Have scanned for and removed malware, have un-installed and re-installed firefox, but it is not functional. Chrome, Safari work normally. Prior to this, firefox was crashing every time I tried to attach a doc or photo. Help!

Chosen solution

Does this still happen when opening Firefox in Safe Mode?

If not, my first guess would be that it's a hardware acceleration related issue, which can usually be resolved by disabling hardware acceleration in the settings.

NOTE: Your may need to restart Firefox for the changes to be applied.

If that doesn't help, it could be caused by a faulty extension that you have installed in Firefox. In that case, you will need to use a bit of trial and error to find what one is causing the problem.

Hope this helps.
