I use multi-account containers extensively. Unfortunately, my laptop recently broke so I had to pull out my desktop which was in storage. I hadn't used my desktop in a few years, so I had to update Firefox to make it work. Then I discovered that the multi-account container feature no longer works. It says it isn't supported in this latest version. Is there any good way to fix this? The multi-account container feature was what finally let me switch to the safety and privacy of Firefox. Prior to that, I used Chrome, but the multi-account containers were even better since I didn't have to tie a different account to each container. It looks like I could roll Firefox back to an earlier version, but that would require creating an entirely new firefox account. It took me a substantial amount of time to get this one set up the way I like. I understand that you all want to protect my data, but frankly I feel like I've been put between a rock and a hard place. Thank you for any help you are able to provide.
