Well, there is a lot of panic about the change from Mv2 to Mv3, and also a lot of misinformation. It’s correct that Mv3 adblocker are somewhat less effective (independent tests don’t show much difference, but in change offer a way better security).
Inbuild adblocker won’t be affected and in other extensions not related to adblocking, it’s irrelevant for the user if it is Mv2 or Mv3.
Mv2 will disappear sooner or later, same as Mv1 in 2013.
Some Chromium Browsers still support Mv2 extensions some time longer (Vivaldi, Opera, Brave), naturally all FF forks, probably until next year, but Mv2 is dying, yes or yes. Only problem exist for uBO, due to it’s specific structure need to be practically remade from scratch to be compatible with Mv3, until now Gorhill only released uBO Lite Mv3, Meanwhile AdGuard and Adblock Plus already are in Mv3
Differences
Recent research and implementation data reveal several key advantages of Chrome’s Manifest V3 (MV3) over Manifest V2 (MV2):
Security Improvements
Enhanced extension architecture that limits access to sensitive data[1]
Disallows remote code execution, requiring all code to be contained within the extension[2]
Stricter privacy protocols that minimize data collection[1:1]
Performance Benefits
Optimized resource management through updated background processes[1:2]
More efficient performance through the new declarativeNetRequest API[3]
Anti-Tracking Capabilities
Recent studies show MV3 ad blockers blocked approximately 1.8 more trackers per website compared to MV2 versions[4]
Specific improvements in individual tools:
Adblock Plus MV3 blocked 21.5% more trackers than its MV2 version
Stands MV3 showed a 45.9% improvement in tracker blocking[4:1]
Enhanced Combined Protection
Using multiple MV3 ad blockers together significantly improved anti-tracking effectiveness compared to single blockers[4:2]
No reduction in ad-blocking capabilities compared to MV2, contrary to initial concerns[4:3]
panic about the change from Mv2 to Mv3, and also a lot of misinformation. It’s correct that Mv3 adblocker are somewhat less effective (independent tests don’t show much difference, but in change offer a way better security).
what do those test measure? only what is visible, that is percentage of ads hidden? or does it take into account all the tracking shit regular ublock origin can thwart? I don’t buy that it’s “somewhat” less effective, and neither that it is more secure.
Mv2 will disappear sooner or later,
that’s not a problem with browsers like firefox, where the webrequest api was kept for Mv3.
Only problem exist for uBO,
there are plenty of other addons that make use of the webrequest API, they are just not so well known that half of the average desktop users know it. those are affected too.
due to it’s specific structure need to be practically remade from scratch to be compatible with Mv3,
that’s false. ublock simply cannot do lots of things with Mv3 that it can with Mv2. lite is lite for a reason, and not because in short time thats all he could put together.
then your quote just brings up google propaganda. restrictions of useful features are dressed up as “security”, just like google does it again but now with android with a different approach.
As said, the differences in adblocking is irrelevant, way more important the improved tracking blocker of Mv3. You won’t see any ads using uBO Lite, Adblock Plus or AdGuard Mv3. Apart with an inbuild ad/trackingblocker it’s irrelevant, there don’t exist the limit of filterlists like in the extension…
Anyway it isn’t even worth such panic about this, there are always enough tools out there to show the middlefinger if you are worried about it, I’m not.
