I am running Firefox 31.7 ESR version and I am experimenting with the latest version of Pale Moon. Neither one crashes on me and Flash runs fine, but on YouTube I am using the html5 player. I save cookies that I wish to save by using that feature in CCleaner. I object to the bloat that is becoming more and more problematic in Firefox as they add more features that I could care less about. Pale Moon could soon become my main browser of choice. Maybe as soon as during this weekend.
