FF constantly develops problems logging into web pages; I will enter the correct u/n and password and click the login button, and it simply won't log in, it just refreshes the page and asks for my log in again. The same u/n and password work fine in other browsers. And nothing I've done has fixed it--uninstalling all my extensions, refreshing Firefox completely, clearing all cache data--nothing works. FF also will develop problems with the lastpass plugin, where I also can't log into my vault via the plugin--the same thing happens. It will just refresh the log-in fields without logging in. I can only fix that one if I go to the Lastpass website and log in there--then suddenly the plugin works, until I log out of LP again. Frankly, the problems with FF only seem to grow over time. I love the privacy focus and it being a Mozilla product. I hate how everything in it constantly breaks functionality.
