adblocker VS uBlock-issues

No well-known content blocker "process about 90,000 regexps" to find out whether a resource needs to be blocked or not, that's just not how it works internally.

Last time I ran benchmarks of all well-known content blockers using Ghostery's benchmark tool[1], all of them could process a network request under 20µs on average.

Some do have performance concerns, but it has nothing to do with network filtering, it has to do with other stuff they do beyond network filtering (for example see [2]) and declarativeNetRequest does not help there, so they will still suffer these performance issues under MV3.

Only benchmarking can tell, we shouldn't make assumption about this. Currently the only comparative benchmark which I know of is ghostery/adblocker and running it with the latest static filtering engines shows uBO performing better:

With that in mind, uBO's blocking engine is currently the fastest as demonstrated by latest Cliqz's benchmarks, so the "quicker" claim does not hold either.

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.
