i mean… blocking lists are universal, but the other features ublock offers are not - i'm making heavy use of ublock's dynamic filtering panel and per-site switches. one important thing i use ublock for is to whitelist which sites get javascript permissions and to get rid of remote fonts to make pages more readable. those features need manifest v2.
if firefox drops manifest v2 and you're relying purely on those inbuilt blocking lists then you might as well use the manifest v3 version of ublock without seeing a difference, right?
I think they said they will go out of their way to keep the extension APIs in Mv3 that uBlock needs
Can confirm, I was thinking about switching off of Chrome due to this but since I don't use the custom stuff (much) I'm not noticing a difference with the v3 compatible "light" version of uBlock Origin.
