Don't know. I was diagnosing random slowdowns when making 0.85 using Firefox's own performance analysis tool, and the DOM repaint would sometimes stall for 1-3 seconds. Whitelisting in Adblock Plus did not change anything. Disabling or uninstalling fixed it.
You can also open a new tab and enter about:performance to get a simplified analysis of whether any of your plugins are slowing things down. (Firefox only)
Holy shit, that was the problem the whole time. I disabled Adblock Plus in my FF and after playing some arenas on normal, it was so lightning fast I couldn't believe my eyes. Even playing on PFUDOR is fast. The blip when hitting the space bar to go to the next round is minimal now. And a banner changed with my dawn event so perhaps it fixed the banner rotating problem, too.
I have Adblocker for YouTube and that didn't seem to make any speed difference, it was the Adblock Plus slowing things down. On the analysis, my Self-Destructing Cookies slows my browser down at times and I never would've guessed. Thanks for the knowledge.

ABP is well-known to be slower and more memory-consuming than its contemporaries. Switch to uBlock Origin.
I'm trying that out right now. Looks like it's blocking even more shit than Adblock Plus did, especially on porn sites.
As for browsers, Chrome is horrible, I'm never switching to that. Too bad Firefox fucked itself up with that one update a few months back. I've had annoying problems with it since then no matter how many updates it gets. It never seemed to recover and return to its former glory.
