If we can't fix the underlying issue, maybe there is a way to detect this slowness and offer the user some options.

We need to qualify this further before it's actionable.

This is the reddit thread where this came from:
http://www.reddit.com/r/IAmA/comments/19x7up/we_are_the_firefox_user_experience_team_this_is/c8s44v8

Maybe there's something in there to make the issue more reproducible (didn't have time to read through it yet).

Consider: 

bug 754604 - Performance regression with many open tabs.

– and more recent: 

bug 1089917 - Firefox is very slow with many tabs with heavy graphics

> Summary: Firefox is very slow with many tabs → Firefox is very slow with many tabs with heavy graphics

This lacks a testcase. And using Firefox on Mac for the past couple years, I can't say I've seen a general slowing over time with many tabs.
