It is possible to write your own extension and still use it in Chrome as long as it's not bundled. It would be a huge pain to get the source for uBlock origin and implement it locally yourself, but it might be worth the pain to block ads.

#63Vivaldi 8.1 still supports it (Chromium 150) as loaded unpacked extension. Edit: and latest August 14, 2026 Chromium 152.0.7977.38 based Snapshot https://vivaldi.com/blog/desktop/address-field-calculator-an... has this in patch notes: "[Extensions] Re-enable and extend Manifest V2 extension support for the time being (VB-130324)"
I wouldn't be sure this is a long term solution. Maintaining a this into perpetuity would probably take a lot of resources that Vivaldi team might not have.

That's pretty cool. Thanks for pointing that out. I don't see where it says 'on every update' unless you're referring to the automated checks? I've always wished extensions had more granular permissions though (a la phones, but more so). I think automated ai security checks sound promising soon.
Automated checks are done for every extension on every update. But their recommend extensions they feature on the Extension store, they do other extensive checks for each update.

They could save themselves the trouble if Firefox simply baked in its own ad-blocking, but since Google basically owns them, we all know that will never happen. Ladybird browser is going to be awesome.
See, this is the kind of thing that makes Firefox cool. They have not only just as good of developer console tools as Chrome, they have forward thinking, truly user-oriented policies. They have had trouble in the recent past at securing funding, but something tells me their user philosophy might save them when all the others turn completely to corporate greed as their main operating mechanism (if they already haven't).

If only they focused on making Firefox the definitive good browser instead of a platform for their AI efforts. Firefox will never convince people to leave chrome on philosophy alone. I detest Chrome with a passion and refuse to touch it with a ten-foot pole, but cannot in good faith recommend Firefox to anyone in today’s world. “It kinda works” is about as far a compliment you can give it.
"It kinda works" is factually incorrect. I have used Firefox exclusively every day on macOS for the past year, several hours a day, and have not one single time had to open another browser. None of the customers of my B2B saas use Firefox. Not once have I needed to test in their browsers except quick smoke testing to prove to myself that the rendering and details are identical. All my other browsing is indistinguisha…
Agreed, I can't understand where these experiences come from.
I only ever use Firefox, at work, at home, mobile. Since forever, as long as there has been a Firefox (and Mozilla before that, Netscape prior).
There was one time about 8-10 years ago that I encountered a site that didn't work in Firefox, was some weird proprietary training module at work.
So yes, I did encounter one site that didn't work in Firefox in the last ~20 years. One.

The original uBO relies on Manifest V2, the API Chrome no longer supports. It's impossible to run full UBO (not Lite MV3 version) on current versions on Chrome.

#68Support Firefox. F** Chrome.
Fix?

#69For those who use uBlock Origin Lite, have you noticed any issues/deficiencies in what ads are blocked? I haven't.

Your reply makes no sense. To the original point, if they had user-oriented policies, they'd have ad-blocking baked in by now. But they don't, and likely never will.
