FWIW, I've been seeing some odd 'laggy' behaviour in F21 on my desktop
lately, which does mostly seem to be in Firefox. I do have sixteen
zillion tabs open, but I do that a lot and it's not happened before, and
RAM isn't exhausted (I have 16GB, using about 8GB). I don't have Flash
installed. Not had time to look into it in more detail yet, but it does
seem like something squiffy is going on.
The symptoms are basically that things like switching tabs, highlighting
text, copy/pasting, or input appearing after I start to type lag by 1-3
seconds, and sometimes presses/characters that occur within the lag time
are lost.
I'm having problems with FF on Fedora 19 that just started recently,
maybe related, maybe not. In my case, the entire desktop is
freezing--even the mouse cursor won't move for 5-10 seconds. It
always seems to happen when opening a new blank tab in FF.
