This really more of an addons.thunderbird.net question than a Thunderbird question, but is there any way to search for extensions and only get results that support a specific version of Thunderbird (specifically 78.x.x)? I don't see any version filtering option on addons.thunderbird.net, and even in Thunderbird 78's UI, the recommended extensions screen will often show extensions that aren't compatible. Since the VAST majority of extensions don't support the current version, this makes sifting through search results to find something that works challenging. Is there an advanced search URL hack (e.g. appending something like "?minver=78" to the URL) that will filter results?
If Mozilla's own addons site doesn't have a filter-by-version capability, is there a third-party repository that does?
