i am at my wit's end with firefox on my fedora rawhide system -- to say it's nad-grindingly slow would be charitable. just now, i tried clicking on another tab ... some 30 seconds later, i am still waiting for the tab to change, oh, wait, there it is.
watching any sort of youtube video is excruciating ... while audio is typically, i will frequently get *maybe* one frame change a second, i kid you not. i frequently get javascripts that are not responding, and i'm asked whether i want to wait for them.
is there *something* i can do to debug this? what firefox configuration settings should i be looking at? i'm willing to try anything because, at this point, firefox is utterly unusable. even something as simple as scrolling in a window is painfully slow.
oh, and i'm on a quad core i7, so i'm pretty sure horsepower isn't the problem.
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.
yup, those are/were my symptoms *exactly* -- it's much better now that i've disabled flash but that shouldn't have been necessary, should it? i'm on a quad core i7 and also have 16G of RAM and not even close to using all of it most of the time.
so it's a bit of a relief that i'm not the only person seeing this.
FWIW, I rebooted yesterday afternoon to the latest F21 userland and kernel 3.17.0-0.rc6.git2.2.fc22.1.x86_64 from rawhide-kernel-nodebug (I've been using those kernels all along) and haven't seen the laggy behaviour in Firefox since.
