Every now and then I carry out my own manual garbage collection of tabs: iterate through, copy URL of any I don't really need right now, collect the URLs in a text file somewhere. I usually end up losing the text file but no disaster ensues. I'm currently running with 19 tabs open. Any more than that and it becomes too difficult to identify them. Ideally, I try to trim it down to about 10 when I can. How anyone can be even remotely productive with 300 open is beyond me.
