But yours and my general anecdotal experiences aren't useful. There are hundreds of millions of Firefox users; we [EDIT: i.e., you and I] could have great or horrible experiences and they would indicate nothing. Perhaps if we could point to specific bugs our posts would be substantive, though still probably not of much consequence. We need data.
For instance, somebody just landed a pretty tricky bit of code to fix a severe incremental GC performance fault he'd been experiencing with a lot of tabs open (disclaimer: I reviewed the patch): https://bugzilla.mozilla.org/show_bug.cgi?id=1214961
I moved to Firefox a while back in futile protest at the big G ... but I've come to truly appreciate it.
It's the much better browser. Not sure where Chrome is nowadays but I remember it looked clean, and was like lightning at the beginning. Crapware now (or when I left it).
Appreciate these moves. Long live the fox.
* Although we're currently running an A/B test to measure performance differences with e10s enabled and disabled, so you might fall into the disabled cohort when you run Dev Edition. This experiment is scheduled to end in a few days.
Nit: you mean (js-based) addons/extensions, not (binary) plugins.
