And when Manifest v3 is fully enforced in Chromium (current date is slated to be July 2024), then the more restricted uBlock Origin Lite would need to be used instead.
(I’m not sure if Arc will fully adopt v3, but they might not have a choice at some point in time.)
Filter lists update only when the extension updates (no fetching up to date lists from servers)
Many filters are dropped at conversion time due to MV3’s limited filter syntax
No crafting your own filters (thus no element picker)
No strict-blocked pages
No per-site switches
No dynamic filtering
No importing external lists
TL;DR: The way uBlock Origin works on Firefox right now is already better, but if Arc has to go along with Manifest v3 in Chromium in a few months, then it’ll be even more of a differentiator.
It also looks like they’re even thinking about rolling out their own tracker blocker (instead of using uBlock Origin) as a result of the Manifest v3 changes:
Yep, same. FF has been my go to browser for years
Genuinely don’t comprehend why anyone uses anything other than Firefox. FF + uBlock makes the internet so much better
Arc has uBlock installed by default. So that’s not a differentiator between the two.
It certainly is a differentiator: uBlock Origin already works best on Firefox. https://github.com/gorhill/uBlock/wiki/uBlock-Origin-works-best-on-Firefox

The Lite version still works well considering all the restrictions, but has a lot of limitations: https://github.com/uBlockOrigin/uBlock-issues/issues/338#issuecomment-1507539114
