uBlock-issues VS focus-ios

There is an open issue for this: https://github.com/uBlockOrigin/uBlock-issues/issues/2786 uBO should report such filter as en error in Firefox, so that is the thing to fix.

This would be the price of one of the four CDNs (6000$ per month): https://github.com/uBlockOrigin/uBlock-issues/discussions/2958

opened a bug report https://github.com/uBlockOrigin/uBlock-issues/issues/3003

Current estimated cost for just ONE of uBO's CDNs: HERE. This is with other lists updating every few days. uBO's not a company, it's a volunteer project using free services, which have limits that we cannot cross.

The extension with the best success rate seems to be **uBlock Origin**. It is a community driven project with a team of volunteers, you can review the source code [here](https://github.com/gorhill/uBlock). You will need to update your filter lists regularly, this because Youtube changes detection methods daily. Here is how you do that:

Definitely a much-needed area for development. However, having gone down the browser extension rabbit hole, I've largely shifted my focus to user scripts. Granted, there will always be a need for specialized browser extensions like ad blockers (uBlock[1]), keyboard shortcuts (Vimium-C[2]), and password managers (Bitwarden[3]).

That said, I find user scripts superior for most tasks, despite some lacking UI niceties. They are easier to share, use, and crucially, audit—be it in terms of scope, permissions, or code updates. Plus if Manifest V3 is any indicator, the future for browser extensions looks bleak. While I don't agree with this direction, it's probably for the best for the majority of users, like my mom.

Your effort is commendable; however, should you find yourself looking for a viable pivot in the future, I believe the user script space is primed for innovation and could offer a good alternative.

When Mozilla launched Focus for iOS in 2016, Apple had two WebKit implementations on iOS. Focus was implemented with UIWebView (slower, with more extensive content blocking capabilities), while Firefox was implemented with WKWebView (faster, with limited content blocking capabilities).[1]

Focus was Mozilla's way of offering Tracking Protection on iOS in some form without slowing down the performance of its main Firefox for iOS app. In addition to blocking ads within the Focus browser itself, Focus also provided iOS content blockers, which ironically (due to iOS content blockers being exclusive to Safari) allowed Focus users to block ads in Safari but not in Firefox for iOS.[2]

Focus migrated to WKWebView in 2017 after iOS 11 bridged WKWebView's feature gap, allowing Focus to retain its Tracking Protection feature through the transition.[3] With Firefox and Focus both on WKWebView, Mozilla then ported Tracking Protection to Firefox for iOS in 2018.[4] Tracking Protection improved Firefox for iOS, but could not be as comprehensive as the Safari-exclusive content blockers.

By that time, Mozilla had already launched Focus for Android in 2017 even though Firefox for Android already had the ability to block ads more comprehensively with extensions.[4] As a privacy-focused secondary browser, Focus was a niche app that turned out to be well-received by users, and Mozilla probably did not have a good reason to discontinue it even after Firefox for iOS gained Tracking Protection.

Feature request is at https://github.com/mozilla-mobile/focus-ios/issues/2970 but it's been stale for a year.

The next update is supposed to fix this: Links should not open outside of Focus by default.

Just did, I'll link it here too just in case: https://github.com/mozilla-mobile/focus-ios/issues/3673
