Predicted it. Firefox is just going to do what Google does, only a bit later. I don't know what effect exactly V3 has on extensions. Did it kill uBlock Origin? What about uMatrix? In any case, I only haven't moved to something like Basilisk yet because figuring out how to configure it to be as private as LibreWolf is probably a huge pain.
Both Chromium and Furryfox still support V2, but Goolag has already stopped accepting V2 extensions to be submitted into their extension store earlier this year, and they're set to completely delete V2 by the beginning of next year, no wait, by summer of this year.
This is why uBlock Origin and uMatrix still work for now, but won't be for long.
Especially uMatrix because that one is no longer maintained, but uBlock Origin has a "lite" version designed for V3, which even the developer himself admits is way less powerful than the regular one, which is V2 only.
I wonder what the LibreWolf people are going to do about that. Hopefully not nothing. Anyway, Brave is supposedly going to keep V2, and if this really is as bad as it seems, I assume a lot of people are going to move from Firefox to that (because it's pretty safe to say that a lot more Firefox users block ads), which is not good either.
As I already stated in my blog post, even with Brave, Goolag still has the power to make them dump V2 by making it as much of a hassle to implement it back in again and again for example.
The only way out in the long term would be to fork the browser, and just continue development independently from upstream, but unless they master the entire Blink soyce code (good luck with that!), I won't see them doing that anytime soon.
I kind of expect forks of Ubuntu switching over to Debian or Devuan in droves, which we're already seeing more and more of.
Because Canonical makes so many bad decissions (and keep doubling down on that too with every new LTS release), there are literally "beginner friendly" distro's out there based on Ubuntu, who have to waste so much time and energy removing all the crap nobody wants every single time, perhaps Mint and Pop OS will continue to be Ubuntu forks for a few more years since they have much bigger teams, but the smaller forks like Vanilla OS for example went like "fuck it, we'll be based off Debian instead of Ubuntu from now on!".
It may be a Firefox type of situation. Saying they won't do it so that people think that this doesn't matter and won't affect them, but then after half a year it's removed from Brave too and then everyone is fucked. Of course, I'm not gonna fall for that, fuck Brave, I'll go with Basilisk. Or even webkit or webengine browser, though those lack extensions. Really, I'll stop using the internet before I accept watching fucking ads.
If ads and trackers are the only things you want to block, you could consider using a PiHole, or even easier, modify the /etc/hosts file to block all the spyware hostnames, and then you can use whatever browser you want.
But the clearnet is so hopelessly broken, there's a massive need to block far more than that, like all the covAIDS propaganda (which will finally be gone soon), 3rd party JS and CSS (just fucking learn how file management works before you code!), custom fonts (browser default is the only font you need!), and other bloat.
And if you go down the /etc/hosts based blocking path, you'll quickly see bars of empty divs everywhere, because soytes reserve that space for ads, which uBlock Origin can remove those divs along with the ads.
Hell, last time I checked Mixi in a WebkitGTK browser, I was shocked by the sheer amounts of ads littered all over the page, it made their propaganda literally unreadable!
At least we have a privacy condom for that now: https://mixi.owacon.moe
And yes, owacon.moe is the new domain specifically for privacy condoms hosted by 076.
Yeah, blocking ads is just not enough anymore, which is why I'll probably go with Basilisk, when the time comes, unless something else becomes viable. Again, I wonder what the LibreWolf project is going to do, because this change will really go against the entire point of it existing at all.
