Language pack not available after upgrade

Been using Thunderbird for several years now and since the automatic upgrade to version 68 my French language pack has disappeared. Thought I’d just install it again only to find it is no longer compatible with my latest version of Thunderbird. It’s important to me to have it as I send a lot of emails in French and English.
Any ideas please?

The add-ons home page has a forum. You could ask there.

The French language pack for TB 68.1 32-bit (Windows) is available here:

You may have to set the preference intl.multilingual.enabled to fr in Config. editor (see the release notes).
