They’re still great, but can be annoying. By the end of the day I always end up with far too many of them open, a minute ago I did have about 20 open in one window, and FF was using 280Mb of ram, it’s worth it, but slows down my PC like mad.
Is there actually a name for having far too many tab’s? I mean, it can’t be good (for you or the computer), half the time I look back at them and wonder where the hell it came from.
Ah well, FF tabs still beat IE tab’s 
Even if they are hungrier.
Im usually pretty good at managing tabs. I rarely have more than 7 open at once.
As for memory – FF a huge guzzler! (for me anyway)
I get that too sometimes. You end up with 30 or 40 tabs and then you lose track of everything.
The best solution I’ve found for this is that you have to spend a little time tab managing – close stuff when you’re done with it, or don’t open it at all unless you’re going to deal with it, and then close it when you have.
I have 7 tabs open right now, which is *very* light for me.
