Does Firefox use all your CPU?

Is your computer very slow because Firefox uses a lot of CPU even if it's not actively doing anything? For the past few days my computer was slow in general, and Firefox was horribly slow. The reason was that Firefox was using more than 70% of CPU all the time -- even when Firefox was idle. A quick Google search took me to the solution:
If you encounter problems with sites do not just complain that FF is not working but post the site address here for other people to check. No one doubts that you have problems but to decide if it is a FF problem or something with your system we must be able to check these sites.
I closed a few tabs (which I had open for the past few days), and my machine was back to normal :-)


  1. Plus it gobbles up plenty of system memory. Try using FF with 4-5 windows open.... after 20-30 minutes of usage it will gobble up 100+ MB.

    But I'll still use FF because of some extensions. But may switch to Opera anytime..I was a big Opera fan.

  2. I still use Firefox. I have no other option as of now. I tried Opera a few months back; Gmail chat doesn't work very well on it.

    Gmail, Google Reader, and a few other Google sites are very important for me as I use them all the time. Until there's a better browser I'll have to wait. (I wish Apple port Safari to Linux.)
