You can display the Add-ons Manager with a click on Tools > Add-ons. You may notice that Options buttons are missing on the Add-ons Manager page. Any extension that is listed as compatible with Thunderbird 60.0 or higher will install and run just fine in the email client when version 60.0 gets released.Įxtensions that lists a lower version of Thunderbird can still work in Thunderbird 60.0, but those need the flip of the preference unless the author pushes out an update before the official release of Thunderbird 60.0. Add-ons that are not will be disabled and if you try to install an extension that is not marked as compatible with at least Thunderbird 60.0, you will get the "could not be installed because it is not compatible" error message.Īll extensions listed on the official Thunderbird add-ons website list minimum and maximum compatibility information.

Probably the biggest change in regards to extensions is that Thunderbird will only load extensions that are marked as compatible with Thunderbird 60.0 explicitly. The changes are not as dramatic as those introduced in Firefox 57 but users may still run into compatibility issues. Some of these affect the handling of extensions and themes. Thunderbird 60 will introduce a lot of new features and changes. Thunderbird 60.0, just like the Firefox 60 release was, is a big release that moves the email client from the old Extended Support Release to the new 60.x development version. The next version of Thunderbird will be Thunderbird 60.0 if no last minute minor version is released before it.
