Anecdata: I use FF<current> heavily on a daily basis and haven't seen any of these problems. Issues of this magnitude are "set the internet on fire" problems. If a few web searches don't turn up tons of other users having these problems then it's best to assume there are local issues that need troubleshooting. Some suggestions on that: 1. Have you tried troubleshooting Firefox via Safe Mode? https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-using-safe-mode https://support.mozilla.org/en-US/kb/troubleshoot-firefox-is... 2. If troubleshooting via #1 doesn't help, consider using the Profile Manager[1] to create a new, blank profile and see if your problems reproduce there.
