For the past few months I've been experiencing a host of difficulties with Firefox. When I open a new window, the appearance is totally different from what the original window was, with the "Open a new tab" button on the left instead of the right, and the current tab that opens is not visible in the bar. When I try to change this in the settings, it just doesn't seem to take. This same problem is true for any window, secondary or otherwise. If I close everything, open a new session, change the settings to how I like them (which I have to do every time) and then close that window, nothing stays the way I set it. Also, the browser runs extremely slow. And when I say extreme, I mean it can take 20 minutes to open a new session. And once I start using it, it likes to periodically speed up to a normal pace for a few minutes, hours, days - it's not predictable - and then come to a crashing halt again. The final problem is less irritating, but equally perplexing. I have a few folders in my bookmarks toolbar that contain anywhere from 10-50 websites each, and they like to spontaneously auto-scroll to the top of the list, despite my attempts to scroll down. This problem just goes on and on until it suddenly stops for unknown reasons. I would really, REALLY appreciate some help clearing up these problems. Thanks!

I see such issues my self.
It usually helps to close and restore that tab (History > Recently Closed Tabs; Cmd+Shift+T) to make the others appear.
