4 browsers that will continue to support uBlock Origin and other ad blockers with Manifest V2

This is a most excellent place for technology news and articles.
the answer is 1
it’s Firefox
Vivaldi is supporting for less than a year (June 2025 it stop) and edge is unclear but may support it simultaneously (at least for now). Brave has “partial support” which means it may as well not and they’ve left a “lot of wiggle room” to drop support in their statement.
If you want to keep using ublock origin, get Firefox. You should just get Firefox because it’s the best browser for privacy/not using chromium in general and it works well.
Does Firefox use “manifest v2”? When reading all the frothing news about this stuff, I assumed the “manifest” thing was a Chromium thing.
If I remember correctly, yes. There was a pain in the ass a few years ago when Firefox switched from their own add-on system to one that matched Chrome's, despite Firefox's being more powerful and mature. The goal was to make it easier to port Chromes (arguably) greater variety of add-ons to Firefox.
It was an unpopular decision and it was the start of a downward decline for Firefox. People that had their browser "just the way I like it" found themselves starting fresh essentially, and without some of their favourite add-ons.
Damn. That means they are once again on a divergent path.
How so? They can support Manifest v2 and v3 simultaneously. It's a bit harder for their old add-on system since that add-on system had more hooks into the browser, but v3 is largely just a restriction, so there won't be much conflict there.
Ah, if it’s easy to just maintain both, and v3 is largely backwards compatible then I’m mistaken on how divergent v3 is.
Defanged/declawed v3 is a weird thing to have exist. It’s a bummer that Chrome got to set the standard. And then they took that and restricted things. This isn’t a healthy standard.
If FF ever drops V3, it'll be because they have extensions to bring parity to V2. There is maintenance overhead, but I doubt it's anywhere close to the old add-on vs V2 differences.
