Rated 3 out of 5 stars

Decided to download TB10 after getting a message 2 days in a row that it was urgent to do so. Then had a heck of a time getting it restarted. After I did and all seemed to be working well, inc. the spell check that wasn't even supposed to work onTB10, I took the advice of another message and downloaded the Lightning Calendar and the Converstion add-on. The instructions on the download page said to click on the option in the add-on tool in the mail program and install the 2 add-ons. Well, there is no option to do that in my program and I can't get these to work any other way than to chase all over the net looking for a program I can trust to download and use to open them. Am very frustrated. At least I feel compensated by having the spell check work.

This review is for a previous version of the add-on (2.2.4).
