If you lose the calendar see calendar update issues and check to install dependencies on your operating system (such as xul-ext-lightning).This screenshot either does not contain copyright-eligible parts or visuals of copyrighted software, or the author has released it under a free license (which should be indicated beneath this notice), and as such follows the licensing guidelines for screenshots of Wikimedia Commons. Note: After Thunderbird 52, Lightning is built-in rather than obtained through the extensions. Unable to edit because i think Mozilla hates those of us who have had an account for a while, i instead edited which i could sign up fresh for with GitHub in 20 seconds (OK, that gives me at least three separate Mozilla accounts, yay)- anyway, i added this note to i hope help others: Thanks to Chris Thompson for figuring this out, this fixed it: sudo apt install xul-ext-lightning

My Lightning extension was reported as no longer compatible.

I have a WebExtensions process permanently using 116% of my CPU (out of 1200%, but still). Then i found out that was because the whole damn calendar was gone.Īfter following these instructions - resetting extensions.installedDistroAddon.
