Thunderbird upgrade

What ho one and all,

After a few weeks of learning the ins and outs of TB, I am getting to grips with v91.1

Now I am receiving the message of an upgrade; should I 'break' a working program or not.

I am currently getting my wife's new computer up and running, and installed the latest TB but I have found that a couple of the add-ons that I have installed in 91, will not work with 102, specifically, Old Icons.

If I upgrade following the message I receive, what happens with the add-ons that are not supported? Do they stop working?

Thanks

From the Thunderbird blog...

Thanks for the link; I don't 'do' thunderbird blogs. Guess I will just have to wait until the add-on is upgraded or find an alternative.

The add-on is called, Old Icons. They look nicer than the default.
