Tabs are not in RAM in Firefox - they don't get loaded until you click into them, so you can effectively have a nearly unlimited number of tabs open. (My primary browsing PC has only 8 GB of RAM, but handles thousands of tabs with ease.) As I said above, this is how I work, and it's not negotiable. If it bothers you to have that many tabs open, then fine, kill off your tabs. That's fine with me. And my way should be fine with you. (You're probably one of those persnickety inbox zero people, too :-), aren't you?) (My Inbox has 38K unread messages, and I reset them at the start of the year. That's after the many thousands that Google already threw away. It's just not worth the effort to throw away all that stuff one message at a time...) BTW, I have probably 100K bookmarks, but have no good way to merge multiple old bookmarks files and convert them to the new format, so unlike the tabs, the bookmarks are now useless. I stopped using bookmarks in favor of tabs years ago now. Now let's talk about power tools for handling large numbers of tabs!
