I've been using multi-account containers for a few months now, and loving it. I use the no-container firefox for work, since clicking on links in other apps goes straight there. So I have a personal container, financial container, shopping, and media. The problem usually occurs with financial sites, that have a lot of redirects in their login page. For my privacy, I won't list which ones, but they are major financial institutions with fairly "slick" web pages (slick as in very annoying and overly complicated...). Even setting "always open in container tab" doesn't seem to do the trick. I get stuck in a loop where the login page fires, then it seems to "break out" of the container tab, before redirecting back to the login page. The tab color goes from green to regular grey and back to green. Any ideas on how to fix this? On some pages I'm able to set the "always open in container tab" option on the intermediate pages, but others I cannot. Seems like when the login goes through a proxy or something I can't make it work. Any ideas?
