> I don't think the speed difference between FF & Chrome is noticeable nowadays.

It is, if you turn off ad-blocking. Certain sites will then just hang all of Firefox.

If you notice such sites, please file a bug about them so they can be investigated and fixed.

Which ones?

To see the effect on a small scale, load up a single JS timer[1] and watch the seconds increment by 1 each second.

If I disable both RequestPolicy and Ad Block Plus, loading up http://cracked.com, http://failblog.cheezburger.com/, and http://www.wikia.com/Wikia, and then just blindly clicking around one of those sites, it will cause the counter to jump/skip over seconds.

Chrome does no such skipping (on the same machine). RequestPolicy and ABP seem to help, but not eliminate the problem.

Okay, so that test is totally artificial, but surf the internet for a couple days without restarting Firefox (27.0.1) on Ubuntu (13.10) and Firefox still grinds to a half, taking more than half a second to change tabs or register other UI input.

Rather than debug Firefox, I can just use Chrome.

Shrug, I do this all the time as I never restart the browser. And your timer test is WORKSFORME too :-/
