[ORIGINAL 1 Star]Working adequately until today. Now Firefox 88 on Windows 10 will not load with this plugin enabled.[/]
Firefox updated to 89, so I enabled M-A Containers once more and the plugin seems to be working fine again.

I want to manually add websites, because it can be annoying to get to the website sometimes. But overall good extension.

this plugin is the reason i use firefox and i wish i could give it 100 stars. This should be a default for every browser because this is true isolation in the same window (not just grouped tabs - im looking at you chrome) it just works.

Je ne sais pas comment je pourrais faire SANS

Due to very limited container management functionality, the add-on is almost unusable on many modern sites like Microsoft, AliExpress, eBay etc.

It is known that many sites use redirections to other [sub]domains to perform a login, to transfer the user to a payment service etc. The redirection may be performed several times, so the add-on may be unable to ask the user to establish domain-to-container correspondence. In such cases, the only way to successfully work with the site, is to remove it from the containers, and use only alone.

The solution is trivial: just to allow the user to enter/edit domain name manually, with wildcard (*) support. This would solve most problems described above. I asked about such feature some time ago, but the request was ignored.

Fantastic. The only reason I continue to use firefox.

Version 7.3.0 On MacOS missing hide/show container functionality. I joined a discuss/question on the matter with support. For me, this is very valuable functionality. I will gladly upgrade rating once resolved.

EDIT: Thank you for the Developer response. The "## >" on the right of each container is a Button that takes you to more options, which include "Hide"

The only thing missing for a 5 star, personally, would be the ability to set the order of the sorting of tabs

I hope I can add '*.example.com' pattern in containers' site lists.
