The UI is probably confusing to non-technical people who don't already use Lemmy. I would suggest adopting a similar UI to the Matrix one that another commenter shared, to make it easier for beginners.
edit: also the repo doesn't have a license, so currently the code is not open source.
One of the most controversial changes of Chrome’s MV3 approach is the removal of blocking WebRequest, which provides a level of power and flexibility that is critical to enabling advanced privacy and content blocking features. Unfortunately, that power has also been used to harm users in a variety of ways. Chrome’s solution in MV3 was to define a more narrowly scoped API (declarativeNetRequest) as a replacement. However, this will limit the capabilities of certain types of privacy extensions without adequate replacement.
Mozilla will maintain support for blocking WebRequest in MV3. To maximize compatibility with other browsers, we will also ship support for declarativeNetRequest. We will continue to work with content blockers and other key consumers of this API to identify current and future alternatives where appropriate. Content blocking is one of the most important use cases for extensions, and we are committed to ensuring that Firefox users have access to the best privacy tools available.
No you're thinking of 'active', which surfaces posts with recent comments. Just scroll a bit on 'hot' and you'll see it dredges up some old posts, even without recent comments
I would suggest adding some screenshots to your website
