A few days ago I upgraded to Firefox 3.5 and just yesterday I experienced some epic freezing when a poorly programmed script took over one of the tabs. Like many people, I generally have many tabs open on any given browser window so a freeze can be a big problem if the browser reloads all previous tabs, including those that are problematic. WELL, it appears that the new Firefox has a great fix for this! After the first freeze, I relaunched the browser, which restored all of the tabs and froze again. After relaunching the browser a second time I was presented with this menu.

Yes, Firefox allowed me to restore ALL of the tabs except for the one that was causing problems! I was aware that this technology was being implemented among various browser, but I was so impressed that I needed to share my experience.
