I cannot access the "General" tab in Options.
I recently received a browser highjack due to a sketchy program recommended by a friend. (Last time I listen to them.) I uninstalled the program but and restored my search engine, homepage, newtab page, and all that. (Some through the options, some through about:config) I uninstalled the program, removed all traces I could find through the registry. I even ran a anti-malware program.
However, when I go into the Options menu in Firefox, my "General" tab does not load at all. All of the other work fine, but this one does not. I assume this was a thing the malware did to avoid me changing my preferences, but since I changed them all already through other means, I am mostly annoyed. (At least I think I changed everything back. I would check, but... y'know.)
So is there any way to abilitate this option? Or will I be forced to always wonder if I got everything back to normal?

Your bookmarks and other personal data are stored in the Firefox profile folder and won't be affected by an uninstall and (re)install, but make sure NOT to remove personal data when you uninstall Firefox as that will remove all Firefox profile folders and you lose your personal data.
If you keep having problems then also create a new profile.

I was suffering the same problem and found that disabling Ghostery corrected the problem. I cannot really see myself surfing the web without Ghostery though, so instead I went to Add-ons/Appearance to see if I was using a theme which maybe was contributing. I was still using theme FF came with (Default) and decided to try installing a theme to see if it would correct the problem and lo and behold it did. The theme I went with was Lava Fox V2. I then tried going back to the default theme and the problem re-appeared. So back to Lava Fox for me then. The previous answers helped by pointing me in the right direction so thanks to all.
