Hangs & Slow Script Warnings

[zpao]

I noticed lots of mini pauses with Nightly recently and started getting slow script warnings from dotjs. I've disabled and things seem to be better. Today, I only noticed the problem several hours after my last restart, so it could be that it's just leaking or has it's hand in too many tabs...

Since it's a recent development, I'm leaning towards the change from using PageMods, but I don't know the Addon SDK well enough to say that for sure.

Also of note: I have a lot of tabs (142 at the moment, often more, but most aren't loaded), so I may be above the normal threshold.

Sorry I don't have any hard evidence, but it's something to keep an eye out for!

Thanks for the report! Looking at the code now that it is based on tabs, I am pretty sure I can refactor it so that it only "attaches" to the tab (injecting jquery, etc) if there is a script to load for the domain. I am thinking this should be a pretty big improvement.

@zpao There is a new version up on AMO that I hope helps this issue. If you can try it out with your 142 problems, let me know what happens :-). Thanks.

I'll re-enable it and see how it goes. Thanks for looking into it!
