Maybe re-install, sounds like something ‘broke’ — I never have trouble with Firefox, and I have used it almost exclusively for the past 2 years.
I tried K-Meleon for awhile, which is another browser put out by the Mozilla people....... liked it at first, on certain websites it is quick and snappy (supposedly it is based upon the same source code as Firefox, but in a more stripped-down version??). However, over time and as I went to a lot more websites I found that K-Meleon often seemed more sluggish and I went back to Firefox.
Any techies out there able to compare Firefox, K-Meleon, Safari, and other browers? I also tried Avant for awhile but didn’t find any particular advantage to it and stopped using it.....
there’s also the flock browser which is firefox with more integrated features flock.com
