Dear Generous Help Volunteers, I'm running Firefox 128.13.0 ESR (64-bit) on Windows 11 (Lenovo desktop). If I use a Private Window, does that mean that "Containers" are redundant/not needed? If not, please explain in depth. If I use a Private Window, does that mean that, while I have the browser open, any temporarily saved data can be accessed by any website? If so, could I use a Container, in a Private Window, only for those sites for which I need to keep cookie(s) (i.e. bank logins, shopping carts, etc.). I noticed that SOME container extensions let you select to "Allow in Private Windows" and SOME do NOT. I noticed specifically that "Firefox Multi-Account Containers" will not let you select to "Allow in Private Windows", and my understanding is that this is required for ANY Containers to function. Is that correct? It's a bit confusing. I have had some sites break using the standard browser (with Containers), that will often work if I use a Private Window. '''Often, all that seems broken is the "Captcha"; it just doesn't appear and the form will not complete without it.''' However, it works in a Private Window. I'm a little confused about which does exactly what. I don't use Google or any social media sites and I don't want any of them to have access to any of my information. '''I have also encountered an ongoing problem that is very frustrating and time-consuming: ''' When I click a link in a webpage, 10 to 30 tabs will quickly open, instead of only one, and each has to be closed separately. This happens nearly all the time. Is there a solution to this? With Appreciation & Kind Regards, Anne Fennell
