My biggest problems with Firefox after using Chrome for so long is stability. I find that web pages can lock up the entire browser rather than just a tab, and this isn't just a rare occurrence, when I tried to give it a chance a week ago, it happened several times. I am amazed they still haven't picked up the separate process per tab feature yet.
The separate process per tabs feature has different drawbacks. Notably, it means Chrome uses more memory and can handle way less simultaneous open tabs than Firefox.
Really? That seems odd. I have been using firefox on a 6 year old macbook pro for many years and mac is not exactly there best supported platform. I can't remember the last time this happened to me. Do you have a test case which can be replicated? What's your platform?
The project to do this (Electrolysis) turned out to be a lot more effort than I think people anticipated, and was paused for a while last year to allow some other changes to happen. It resumed this year, and you can follow development from https://wiki.mozilla.org/Electrolysis which includes links to meeting notes and the experimental branch if you want to try it out.
