Have you seen the Firefox pop-up that encourages you to refresh Firefox? And went for it?

This was a mozilla notification. Don't click on it, you'll loose your extensions. I can't stand browsing without a popup blocker.

It was (or still is) due to some error on Mozilla's end. I didn't see any pop up. Was just using one of the extensions & something happened & they were all gone.

Just updated to ver 66.xx, and no problems with ad-block or any other extensions

Not only did I lose my precious AdBlocker, but the attempt to download it again fails every time. Sheesh.
