Following are issues I am having recently with Firefox. They all seemed to occur when updating to 51.0.1. I uninstalled 51.0.1 and installed 51.0 but did not have any improvement.

All-in-One Gestures Add-on is not working on websites but does work in the Add-ons tab. Adblock Plus and/or Adblock Plus Pop-up Addon are not blocking ads as they did with Firefox 51.0. When watching a video in Neflix, when I use the keyboard shortcut 'F' to go to full screen, it goes to full screen then immediately exits.

I would greatly appreciate any help in solving these issues. Please let me know if I can provide further information in diagnosing the problem. Thank you in advance.

Add-ons are mostly written by 3rd parties. It is up to them to keep their programs compatible with the new versions.

Contact their support.


Install an older version of Firefox {web link} Be sure to read everything here.

If you still want to downgrade, look under "I still want to downgrade" Click the Directory of other versions and languages link Look for the directory of the version that you want. But remember that old versions may have security issues.

This seemed to be a systemic thing so I was hoping someone might know of a simple fix in config or... So... I replaced All-in-One Gestures with Mouse Gestures Suite. I did not have to change any of the options as it migrated my settings from All-in-One. I think Adblock Plus is working but the Adblock Plus Pop-up Addon is not working as desired. I installed NoScript. Noscript passed all the Kephyr Pop-up Killer tests except 12, 14 (links 2, 3, 5), 22, and 25 (maybe). I have not solved the Netflix fullscreen keyboard shortcut issue. Will contact them and see if they have a solution.
