Yesterday Thunderbird upgraded itself to a version which will no longer run Lightning. For me, this is a crisis as I need access to my calendar. Please don't suggest I get a working copy of Lightning and install it, as apparently no such thing exists.

How do I roll-back to the previous working version? I am running Ubuntu 16.04. I have no idea what the last working version of Thunderbird was but my current (broken) version is 60.2.1.

Thank you for any suggestions.

That is the first line in the Hippocratic Oath. All doctors have to swear to it. All software developers should too.

I made the mistake of letting Firefox on KUbuntu update. It obliterated all my tabs and all my history. There's nothing left. I had a lot of tabs open with intent to use them to update some astronomy instructional activities. I don't know if I'll be able to find them again.

I don't really have a question except to ask: What fresh hell is this? Is it really that hard to just leave things the hell alone? I'm afraid to ever update Firefox again. If everything else wasn't based on Chromium, I'd be out of here.

Also, it looks like something out of Windows 7.

It's all gone. It's a wonder you didn't delete all my bookmarks while you were at it.

Have an old computer and running Ubuntu
