Google confirms they will disable uBlock Origin in Chrome in 2024
There is a discussion on Hacker News, but feel free to comment here as well.
You're viewing a single thread.
Title is misleading. Manifest V2 will be disabled starting in June 2024 for new versions of Chrome. uBlock Origin will only be disabled if they cannot update to Manifest V3.
There is an implication that Manifest V3 is designed to prevent ad blocking, but if you actually click through the links and read the articles, you'll find:
Improving content filtering support by providing more generous limits in the declarativeNetRequest API for static rulesets and dynamic rules
EDIT: Source
I'm no adblocking expert, and maybe this won't be enough for adblocking to fully work, but it's sounding like it will be, since they conferenced with adblock devs to decide.
Feel free to contradict me, especially if you have evidence. Though I would not appreciate getting downvoted and yelled at for the sole reason of not taking headlines at face value just because they say Google is evil.
Manifest v3 is designed to make ad-blocking much harder. First off the filter lists will be distributed as part of the extension itself, which means that updates will be much less frequent (review can take multiple days, even multiple weeks) and certain types of blocking (e.g. YouTube ad blocking) will be completely impossible.
This gives ad networks a big leg up - they can either use techniques like Google does for YouTube ads to circumvent your ad blocker, or rotate domains etc. fast enough that extension updates are too slow.
I see. Poking around a bit more, it looks like the User Scripts API might still be usable to pull in filter lists, as long as users turn on developer mode. What do you think?
Effectively the end goal is to make adblocking in chrome hard/complex enough that the masses don't use it. What Google doesn't want is what is effectively a one click solution to adblocking. Anything else is unrealistic and unobtainable and they know it.
So by forcing users to use a version that can't be updated daily/hourly you're already making it so you can't block YouTube ads which as of recent require regular list updates.
Or by forcing users to have two extensions or an extension and an external process to download lists you're adding a step that most users won't bother trying to do.
If Google can cut adblocking to 30% of the current user base then that's a huge win for them.
What I'm trying to say is that it's not entirely correct that Google is trying to "end adblocking" but rather their effort is to reduce it significantly within the products they control.
Honestly I don't blame them but I don't think we can be blamed for switching browsers either.
If that's the goal, I don't really mind. Adblocking always used to be a thing that most people don't bother with, so companies didn't mind all that much when a few of us did. If we're just going back to that point, and we adblock enthusiasts don't have to jump through ridiculous hoops to keep doing what we're doing, I see that as a win-win.
Can UserScripts actually intercept requests? I thought this wasn't possible at all with Manifest v3. If so, nothing useful can be done with the lists.
I meant user scripts might be able to populate filter lists for the main extension to do.
Based on the conversation so far, I'm pretty sure extensions can block ads, but the concern was that filter lists would have to be packaged with the extension instead of dynamically updated. User scripts might be a way around that, as they'd allow loading arbitrary code, but I don't know what the limits on that would be.

You'd have to show me the API to do so. I'm reasonably sure the uBlock developers would have thought about this, or somebody else.

Not really. The extensions can give Chrome a list of things to block, but they can't block themselves, and the lists have to be shipped in the extension.

Arbitrary code only helps you if there is an API to call.
Have the uBlock developers been talking about this? I'd like to read up on that if so.
There is this resource: https://support.ublock.org/hc/en-us/articles/11749958544275-Google-s-Manifest-V3-What-it-is-and-what-it-means-for-uBlock-Users-
Here is a summary of a contributor in a Github issue about Manifest v3: https://github.com/uBlockOrigin/uBlock-issues/issues/338#issuecomment-1507539114
uBO Lite:
- 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
So it really is a shadow of its former self.
Thanks! So yeah, I guess there will likely be an issue with YouTube ads, if what I've heard about it updating multiple times daily is true, but they don't seem to be expressing concern about it.
Right now I have two Chrome profiles with two different adblockers trying to get around YouTube ads in two different ways, and both of them are able to do so. One is uBlock, doing what uBlock does with an army of developers updating filter lists, and the other seems to be playing the ad in the background while skipping me ahead to the video. So I do think that even if uBlock's current approach fails, they will be able to find a way.
If things go awry and both my adblockers fail, even if it's just on YouTube, I intend to switch to Firefox, but it's not worth the bother yet.
That's the thing, it is literally impossible to find a way. Currently, they've implemented content-based blocking - the extension looks at requests made by YouTube, and filters based on them. They still need multiple list updates per day, but this filtering does most of the work.
This is completely impossible with Manifest v3. There is only declarative blocking with v3, which allows for max. 30k rules per extension. The uBlock developers will not invest work to circumvent the restrictions: https://github.com/uBlockOrigin/uBlock-issues/issues/338#issuecomment-1253893421
They will be able to block most ads. For more advanced sites like YouTube, they should be able to use the permissions API to request permissions for those specific sites, allowing them to use the scripting API to inject scripts to those pages, thus gaining better adblocking capabilities.
Also, the comment you linked to was a description of how uBlock Origin Lite works, not the issues faced in manifest v3. I didn't read through the whole thread because it was really long, but I did still manage to find those points in there.
Thanks for the very thorough explanation!
