It's OK for me, and I'd guess everyone else, or we'd have had a bunch of complaints.
That means, unfortunately, it's at your end. You could verify that by using another computer with Ffx, it should work OK, the issue is on the PC affected.
I haven't heard of this one before, so if if it happened to me, this is what I'd do:
- delete all user info such as cache and cookies
- run a deep cookie (LSO) cleaner such as CCleaner
- upgrade Firefox
- reboot the PC using a hard reset: power down, remove the power supply lead, hit the power button 3 times (to discharge any power in the PSU or mainboard), replace the power lead, restart
- if still no joy, suspect a Firefox plugin, and remove anything suspect (or all plugins if not too many), then re-install them
- try voodoo
Please let us know what happens - thanks.
