I must admit to currently having 280 tabs open. In my case, I open a bunch of things I intend to read (by browsing reddit or the like) and defer the reading of them indefinitely.
In practice, most of the tabs are `legacy' tabs that I don't use, but which I still retain some nominal interest in when I go clean out the tabs every couple months or so. These tabs range from youtube videos that I don't want to forget, to tips for Vim, Wikipedia articles, blog posts on machine learning, instructions for DIY haptic compasses...
About 1/3 can be traced to one or two websites with interesting articles that I intend to read in depth (at some point).
Your browsing style is very much same as mine. I suppose you are using firefox with vimperator + tree style tab. If you have a fear of restarting the browser again then install bartab[1] extension and forget the fear. It unloads the tabs from memory, so memory consumption is too low and restarting browser takes little time.
