Mac OS X 10.9.5

I have upgraded Thunderbird from 38.6 to 45.6 and it won't populate New Message window - it's completely blank (no sender drop-down, does not insert signature and I can't put the cursor in any fields). It does the same if I double-click an existing template or reply to a message in Inbox.

Have reverted to 38.6 and it works fine again.

Any suggestions? Thank you.

Do you have any extensions installed? If yes, try restarting in Safe mode to see if that fixes the problem.

If yes again, one of your extensions is causing Thunderbird to fail, because it is not compatible with version 45. Go to the menu Tools -> Add-ons and check if there are updates available.

If that didn't help, you have to find which add-on is causing the problem. If you have a lot of extensions, you can divide them in two and disable the 2nd half. If that helps, divide the 2nd half in two and keep repeating the process until you have found the offending add-ons. Then you have to decide if it's worth disabling the add-on or that you want to stay on an old version of Thunderbird. You can also try contacting the add-on developer…
