FWIW, I have 3668 tabs open in Firefox right now. Looks like it's using about 1.6GB of RAM. (Notes: most of those thousands of tabs are unloaded, I block JavaScript rather aggressively, and yes I do recognize the absurdity but I confess my sins here to illustrate my point!) I have no experience migrating from Chrome to Firefox, but FF can certainly handle lots of tabs. Vertical tab layouts are very helpful for navigating them. My limited experience using Chrome says that Firefox requires vastly less RAM to handle multiple tabs (anything more than a dozen!). Re: Conspicuous tab consumption: If I pared down, I'd be more like 50-100 active tabs. I appreciate that Firefox remains completely usable even when I do not pare down. Chrome fails for me at about 20 tabs due to lack of usable vertical tabs layout, even before RAM becomes an issue on this machine.
