What people are saying

I can't provide a source for Google axing a too-invasive extension, because they've never been straightforward about it. My favorite excuse was that the extension's description…

stonogo used a recommendation phrase. One indexed comment matches. This is a phrase match, not a verdict.

uBlock Origin (uBO) Issues This repository is the official community-maintained issue tracker for uBO. Support Forum For support, questions, or help, visit /r/uBlockOrigin. Filter List Issues Report issues with filter lists or broken website functionality in the uAssets issue tracker. uBO Lite (uBOL) Issues Report issues specific to the Manifest Version 3 (MV3) variant in the uBOL issue tracker. Localization issues Language translations are handled at Crowdin: https://crowdin.com/project/ublock Performance Issues Speculated performance issues are marked as invalid and closed if they do not come with actual profiling data from the Firefox Profiler (or Firefox Profiler for Chromium) and a fully substantiated analysis supporting the claim. WebRTC Issues Do not open issues about WebRTC leaking local IP addresses. Supported modern browsers do not cause undue local IP address leaks through WebRTC. uBO is not a VPN/proxy tool. If you are experiencing such an issue, report it to the browser or VPN/proxy tools software provider or, if needed, both. Filter List Requests New filter list requests are not permitted and will be declined and closed. uBO Development Builds Use the development builds to help report issues and regressions before the next stable release. Once you install a development build, it will automatically update when a new version is published. Chromium: Click the most recent uBlock0_[version].chromium.crx file from the uBO Releases page. Firefox: Click the most recent uBlock0_[version].firefox.signed.xpi file from the uBO Releases page. Thunderbird: Download the most recent uBlock0_[version].thunderbird.xpi file from the uBO Releases page, then drag-n-drop it into Thunderbird's Add-ons Manager pane (Thunderbird 91+ required).

I mean, that's a common difference between a SaaS and a self-hosted solution. For a SaaS service a block list can include *.somesaas.com vs a self-hosted service that has it's own domain per owner, meaning you'd have to add every single one to the list. You can always find a common pattern in the URL (e.g. the API), and block based on something else. There's also an issue[0] to block based on POST body.

>I have yet to see where Chrome is explicitly telling anyone they plan to phase out support for adblockers, nor where they are making it clear that is their intention. That was never their intention, not what the uproar was about, so it's to be expected that you're not seeing any evidence of it. The problem with Manifest V3 is not that it disables adblockers; not sure where you got that idea from. The problem is that it severely restricts how effective they can be. Many of the things uBO does cannot be done in v3. That's what the uproar is about. https://github.com/uBlockOrigin/uBlock-issues/issues/338#iss... https://github.com/uBlockOrigin/uBlock-issues/issues/338#iss...

> such intrusions are rendered illegal or impractical The GDPR was an attempt. Guess what happened? Everyone implemented it in such a way as to appear compliant but not necessarily be compliant, and to cause maximum annoyance to the user. What the solution is here is to have an educated population and powerful privacy tools, like uBlock Origin. [1] But of course, the surveillance oligopoly is developing its own browser [2], specifically to maintain control and make it hard to implement such tools [3].

This was implemented as per discussion with AdGuard's people[1]. For now I know of two lists from prominent maintainers which purpose is to remove unneeded URL parameters: - https://filters.adtidy.org/android/filters/17.txt - https://raw.githubusercontent.com/DandelionSprout/adfilt/mas... There are ongoing discussions to include the first one as a stock list (i.e. present in "Filter lists"), though not enabled by default for now. Addendum: to be clear, this is not a replacement for ClearURLs. ClearURLs has more capabilities then just removing query parameters from the URLs of outgoing network requests. --- [1] https://github.com/uBlockOrigin/uBlock-issues/issues/1356#is...
In ClearURLs – automatically remove tracking elements from URLs
