You not support Firefox Multi-Account Containers ?
I restore the tabs but the containers dont work i see ? ((((

You assume this addon works and will save the day when your PC or browser crashes, but the first time in years that it did, not only did Firefox restore my session to a few days ago, but all my sessions I had previously saved, auto or manually in this shitty extention were gone. Its still not even auto saving them. Crap.

I don't recommend this extension. There are many session managers. I've used about 10 or so over the years. This is probably the worst UI I've yet seen.

The main drop down window of this add-on is disorganized and un-intuitive.

Where does it save the backups? In the preferences, it states, "Specify the folder to save the backup file. The save location is limited to the folder under browser download folder."

Does anyone have any idea what "the folder under browser download folder" means? I sure don't. I wonder if it's implicitly assuming the user is running Windows, but I really don't have the faintest idea. I looked everywhere I could think of, and did a search of my hard drive, but found nothing.

I'm very sorry I wasted time on this. Don't make the same mistake I did.
