Email Battles has an article on a new change to Firefox’s JavaScript Garbage Collection. Aparrently there’s a hard limit of 4MB for some JS engine operations so that people using loads of tabs with pages full of JS will kill things. Sounds like what happens every time I go porn browsing or researching something - after a while it’ll just chug up, take loads of resources and I’ll have to either wait a day or two for it to un-fuck itself, or I’ll kill it and lose all my tabs.
