Firefox Crashes When I Right-Click

[PastaGuy]

The title says it all. Doesn't matter what page it is, whenever I right-click, Firefox crashes. I narrowed the culprit down to FlashGot by removing all of my add-ons and replacing them one-by-one. FlashGot was the last add-on to test, and Firefox immediately started crashing upon right-click as soon as I restarted after adding it.

Firefox Version: 26.0
OS: Mac OS X 10.7.5
FlashGot Version: Latest Stable? Downloaded from firefox add-on site. Reinstalled it to test.
Other plugins: AdBlock Plus, BetterPrivacy, DownThemAll!, GreaseMonkey, Reddit Enhancement Suite

Please create a clean profile from scratch. Install only FlashGot, leaving all the defaults.
Does the problem still exist? If not, FlashGot is not the culprit.

Try adding back your extensions, one at a time, until you find the one that causes the issue.
Then remove all the others, pairing only the suspected one with FlashGot, to confirm that the remaining one is the issue.
If the problem is solved even with all add-ons reinstalled, then the previous profile was probably corrupt. Problem solved.

Let us know, thanks.

Crash report numbers (about:crashes)?

Sorry, I shouldn't have said "crashes." Firefox actually hangs. There's no crash report besides the system-generated one as far as I can tell.

I will say that FlashGot used to work properly when I first installed it, so I'm starting to think that another add-on is indeed conflicting with it. The most recent add-on I installed was GreaseMonkey. I'll try disabling the add-on altogether and then disabling scripts one-by-one to see what the culprit is and will report back here if I dig up anything.

I have the same problem. On clean profile too. After clicking my xfce dies, I can only move the mouse, clicking does not work. After closing firefox by alt + f4 everything returns to normal.

Firefox Version: 26.0
OS: Arch Linux 64bit

So I have to disable or uninstall flashgot ? Because without him, everything works fine.
