I've had Firefox Facebook Container and Multiple Containers for quite some time. I've also had two Gmail accounts for quite some time. I've always been able to open both accounts, and until recently, been able to successfully open them in separate containers. Something the last week or so has broken however and the two accounts refuse to be opened in two containers. I NEED to keep my work email/browsing/YouTube separate from my home email/browsing/YouTube. The first one opens fine in it's container. The second one, when starting Firefox, USED to ask me every time if I wanted to open it in it's container (annoying, but tolerable), but it worked. NOW when I try to open two email accounts in separate containers, it just refuses to do it. It opens without them in the container - the first one places into it's container, but the second one refuses to open in its own container. I open a new tab in the desired container (the other one to the one that initially opens successfully), it loads to Google with the RIGHT Google account in the right container, but when I hit email from Google, it totally swaps, opening a new window of the WRONG container and loads the WRONG account EVERY TIME. I can certainly change email accounts at that point, but it's then in the WRONG container, so that I have them both open in the same container. If I try to transfer it to the correct container, it just doesn't do it - it opens a new page in the same INCORRECT container.
This is now broken for me! And it happened just the last week. Is it possible that this can be fixed again? This is basic reason for using containers! If you can't keep stuff separated, like separate Google accounts to keep work and home browsing histories separate, then what the heck is the point of these containers anyway?? I may as well not have them.
