I was in your boat up until a few days ago, when it randomly decided in wouldn't load properly. I force quit it, and then it forgot all my tabs. Now, it actually remembered what seemed like the correct number of tabs, each with the correct container, only the address was gone from every tab!
Other than that, it works well enough for me. My only beef is I can't completely disable tabs, but I don't know of any equivalent browser that can.
