By the way, I installed Oracle (Sun) Java Runtime Environment (JRE) over the OpenJDK (open source). Do you think they're related?

Yes, I think it also happens when I'm just reading an article and NOT doing anything at all.

It also happens when I'm in http://localhost because I'm making a program PHP + MySQL.

Have you tried to create a new profile or start Firefox in safe mode?

Have you tried to create a new profile or start Firefox in safe mode?

OK but will the new profile delete all my bookmarks? and settings? If I'm in safe mode, what's the pros and cons?

Does this mean, I'll have to run safe mode all the time from now on? But I wasn't running safe mode ever before.

No, as long as you don't delete your current profile. You can create as many profiles as you want. Obviously that each profile will have it's own bookmarks, passwords and settings.

When in safe mode, extensions are temporarily disabled. So if the problem is caused by an extension, which is not uncommon, then it will vanish in safe mode.

No, safe mode is only for troubleshooting or for fixing a profile that doesn't even start.

See Firefox General Troubleshooting Steps tutorial.

Hi lovinglinux, I hope it's not of much a burden, I've come to you for help, how come when I FULL SCREEN a YouTube video in Firefox, it just shows half?

Here's an example.

OK, but I tried those it didn't work. The weird thing is on my other computers with Ubuntu 10.04 also this doesn't happen.

Maybe it's my video card Nvida 9500GT. Anyway, thanks for your help.
