After upgrade of TB to 45.2.0, Lightning stopped working. There's no sidebar anymore on the right side of TB's window, and no calendar related menu entries. Updating Lightning to version 4.7 didn't change the situation.

Platform is Windows 7, 64-bit.

Since it was asked for in another question about this topic, a screenshot of the Add-Ons manager is already attached.

Because it didn't work anymore after upgrade of TB. See title.

Anyway, I've meanwhile downgraded TB once and updated it again, which has solved the problem.

Since Lightning is bundled with Thunderbird there is no need to manually update Lightning. It should happen automatically.

Are you saying you did manually install Lightning 4.7? If so, why?

I found a solution detailed under Debian Bugs - https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=833532#50

Start Thunderbird in safe mode.

Enter preferences - advanced - config editor change the value of javascript.options.baselinejit to false.

Restart Thunderbird normally.

HTH!

Don't know what safe mode is and how to start TB that way. However, had this problem again after upgrade to 45.5.0 and simply changing the value of javascript.options.baselinejit to false, as you suggested and restarting TB solved it for me this time.

Thanks a lot.

I'd just hope you'll mention that little detail the next time you have a problem.

Which little detail are you referring to? That I didn't need safe mode or that I've changed javascript.options.baselinejit to false?
