The last time I updated Firefox I had such a bad time I swore never to update it again, however yesterday an addon I use couldn't work without updating. So I bit the bullet and did. I've been regretting it ever since. At best it works slightly slower than my old version which was 61.0.1. At worst I miss the days of internet explorer. The most common issues are 1. White Wheel: When I swap tabs or open a new one I often get a spinning white wheel. This can last anywhere from seconds to at least ten minutes. I've asked around and tried everything suggested, nothing has gotten rid of it. 2. Scripts breaking: This started later on after installing it. Almost any time I refresh a tab or open a new one a script in some other tab breaks. At least twice I was just watching a video in one tab, not even touching the computer and a script breaks in another tab. Please, I just want my browser to run properly.
