So it looks like if you want exactly the same thing that this extension does, you'll have to make sure you're signed out of Facebook in your non-container and non-Facebook container tabs and also delete all your Facebook cookies. When you first install the add-on, it signs you out of Facebook and deletes the cookies that Facebook uses to track you on other websites. I don't want to lead anyone to assume that it's exactly equivalent if it's not!Įdit/Update: From this extension's readme: Someone correct me if I've missed something or if the Facebook Container extension somehow provides more 'containing' of Facebook than I'm indicating here. If we kill the process once it was promptly opening brand-new tabs and home windows, the web browser would certainly most likely open all those surplus tabs when we rebegin it. That's it! It takes some more setup, but it works, and it doesn't cause all of your Facebook tabs to load when you open your browser! 2> Start a new Firefox sessionWhenever Firefox crashes all of a sudden, the previous sessions are recovered once we restart the browser. Once you've got the page loaded in the container, bring up the context menu (right-click) in the body of the page you're looking at, and choose Firefox Multi-Account Containers -> Always Open in This Container. Open a new tab and load Facebook in it (you do not have to log in yet).īring up the context menu (right-click) on the tab (the actual tab UI element at the very top in the tab bar) you've just loaded Facebook in, and choose Reopen in Container -> Facebook (or whatever container you're going to use for this). As soon as you do, Mozilla Firefox reopens the last tab you closed if you closed multiple tabs since you last launched Firefox, you will be able to run. I didn't have to do this because I had already been using the Facebook Container extension, but I'm assuming that if you create any arbitrary container manually that you intend to use for Facebook, it will work. It requires some setup:įirst, if you don't already have a 'Facebook' container, create it. Workaround: Don't use this extension at all instead use Firefox Multi-Account Containers.
