I use Tab Session Manager as a replacement but it's clearly not the same. In fact all my extension replacements are inferior to their previous counterpart (not even considering having to edit an obscure CSS to customize the UI). I still have to restart the browser regularly but now I can't have a restart entry in the file menu. Tip: shift+F2, "restart". My strategy has been to duplicate everything in Chrome and use both, with pinned tabs running on Chrome, especially for Google apps. Another tip: For some reasons E10s wouldn't activate anymore with the update to FF57 (check it with about:support) and I had to create a new profile to make it work .
