it was good, but from March it stopped working.

THE BEST EVER IT BLOCKS EVERY AD EVER

With the latest Firefox update #131.02 downloaded on 10/9/2024, this extension no longer works. It's been a little rocky the past week or so but now it doesn't work at all. Very sad. Hope they can fix it soon as the amount of ads are disgusting, I don't know how anyone uses You Tube without an ad blocker.

I removed, make big difference adds. Put back on.

This extension does not block YT ads at all!

Somehow it blocks uploading to youtube. My videos would get stuck at 0%. I've double checked, this is the extension that causes it.

Absolutely essential for watching YouTube nowadays, when ads are spread randomly even in the shortest videos! It's tiny (under 100 kB) and updated frequently, keeping YT always clean. Note: I've noticed if fails some times, and an ad is played, but it's obviously a Firefox's memory fault, as it starts chocking and crumbling down after playing too many videos (or running through too many badly coded Pages), what can only be fixed by restarting the browser.

This addon BREAKS uploading videos to youtube

The requirement to provide permission for it to "Access your data for all websites" is my only qualm with this extension. As it only needs to work on YouTube I would have thought it would only need permission to work on YouTube (c.f. Control Panel for Twitter, for example, where that extension only requires permissions to access data for *.twitter.com and *.x.com). But it's possible there are architectural reasons why Alphabet make this more difficult. Apart from that one concern, this extension appears to work well in removing the extreme volume of advertising which makes YouTube otherwise unusable for me.
