Multiple problems, as if I'm missing part of Firefox

Basically I had to use Norton's power removal thingy to remove a Trojan virus from my computer. Now my Firefox is acting up. The 3 main problems I've noticed are:

Reblogging Tumblr posts, the reblog section appears in HTML format and I can't change it back. That's annoying. Certain forums are in a simple format, aligned to the left and only in text. This occasionally happens, but refreshing the page is normally enough. Now it always happens, but only for certain forums. Simply doesn't load. This happens with certain video players, reblogging Tumblr posts (it never loads, and no matter how many times I try it just won't - I need to reblog it on Internet Explorer PLEASE DON'T MAKE ME USE IE), etc.

There are a few other problems, but not as big. Overall, these things are really annoying. I've checked, and all my plugins seem to be in place.

Any help please?

And would it be a problem tobackup the user profile and re-install the program?

You can try these steps in case of issues with web pages:

You can reload web page(s) and bypass the cache to refresh possibly outdated or corrupted files.

  • Hold down the Shift key and left-click the Reload button
  • Press "Ctrl + F5" or press "Ctrl + Shift + R" (Windows,Linux)
  • Press "Command + Shift + R" (Mac)

Clear the cache and cookies only from websites that cause problems.

"Clear the Cache":

  • Firefox/Tools > Options > Advanced > Network > Cached Web Content: "Clear Now"

"Remove Cookies" from sites causing problems:

  • Firefox/Tools > Options > Privacy > "Use custom settings for history" > Cookies: "Show Cookies"

Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem.

  • Switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance
  • Do NOT click the Reset button on the Safe Mode start window
