I'm a long-time Firefox user (I probably came here straight from Netscape!) but lately, I'm starting to see tons of issues, often after every update. Things that might help: 1. I'm mostly a Windows user, although I have a Mac. I have a LOT of Windows boxes (don't ask) - a couple of work laptops, some private laptops, a couple of micro-desktops that are connected to TVs and so on. This might be relevant, because they're all synced. 2. My profile is pretty old - over 10 years. 3. I've entirely disabled any ad-blockers or add-ons. So issues happening on multiple machines in the last 24 hours: eBay. Over the last few days, when logging into eBay, if I do a search, I can't change any of the filters along the top Condition, Location, Sort: Best Match etc. I can click on them, but nothing happens. GoFundMe. I tried to donate tonight and when it toddled off to Paypal, it came up with some kind of Localhost error after I clicked on Submit. Did it on Chrome, and it worked perfectly. Fortunately, the money didn't come out multiple times. Oracle E-business. I'm sure many of you use this at work. I genuinely can't login to this using Firefox unless I use a private window. I've cleared my ENTIRE cache. Even went into the Folder and manually cleared it all out. If I try and login without being in a private window, I get "Your session is no longer valid or your logon information could not be reestablished from your session." This is all since the last update to 127.0
