1 year ago It's not officially supported. For firefox was uploaded manifest.json with v2.0 which means soom gonna be outdated and not supports everything. but meanwhile current support of v3.0 not fully implemented from firefox team.
Consider current firefox uploaded version in firefox store as raw-beta, "if it works then it's already good somehow".

Closing for now and waiting for full deprecation of manifest v2 and migrating to v3 when all ready from mozilla side.
When I installed this extension in my firebox with the tree style tab extension, the browser began to load for a very long time and slow down at some points.
