Firefox keeps using 100% of 1 core *solved*

For the past half year or so, I've switched to Firefox on my main desktop computer.  The experience is overall just fine, but I'm getting this irritating issue where occasionally if I watch a flash video, one of my cores (eventually) gets maxed out.  It will never go down until I quit out of firefox.  Closing out of every flash-based tab and even killing the flash-plugin process doesn't stop the problem.  After a while, this seems to have an impact on performance.

Any idea what I can do to fix this?  Here's what I can tell you:
* I'm running 64 bit Arch
* I'm running Firefox 29
* Hardware acceleration is enabled in flash settings
* Ads can also cause the problem but seem less likely to
* Memory usage doesn't seem to be affected.
* Every once in a while, closing firefox doesn't solve the problem either.  I have to actually kill the process.

This is the only system I consistently use firefox on, and I can't seem to find any google searches that follow exactly the problem I have.

EDIT:
Sorry, turns out it was one of the add-ons (vertical tab bar, in case anyone was wondering).
