Navigate to: Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Google\Chrome
With the Chrome folder on the left highlighted, select Edit/New/DWORD (32-Bit Value)
or, if you prefer, on the right side of the screen in a BLANK SPOT, you can RIGHT CLICK New/DWORD (32-Bit Value).
Name it ExtensionManifestV2Availability and hit enter.
Right click what you just created (ExtensionManifestV2Availability) and click Modify. Set the Hexadecimal value to 2, and click OK.
You’re done, but check your work by opening Chrome, and pasting chrome://policy in the URL Address bar and hit enter. You >
should see the ExtensionManifestV2Availability policy, and the value should be set to 2. If you don’t see it, click “Reload Policies” > and/or review your work.
Well, Thorium developer stated he intends to support Mv2 past the 2025 deadline. Whether he’ll make it, we’ll see. It’s a one man show, there was some drama involving it in the past, and there’s the question of what’s the point in maintaining Mv2 extensions support if you won’t be able to install them from the store after they’re cut off?
Vivaldi is supporting for less than a year (June 2025 it stop) and edge is unclear but may support it simultaneously (at least for now). Brave has “partial support” which means it may as well not and they’ve left a “lot of wiggle room” to drop support in their statement.
If you want to keep using ublock origin, get Firefox. You should just get Firefox because it’s the best browser for privacy/not using chromium in general and it works well.
Hardly surprising considering that Brave, Vivaldi and Edge are all based on Chromium. The Brave and Vivaldi team won’t have the resources to maintain Manifest v2 support for each new Chromium version, and Microsoft doesn’t have any reason to support v2 with Edge outside of goodwill.
Brave is based on Chromium, so where Chrome goes, Brave is likely to follow.
Routers and VPNs are only able to filter URLs. They have no way of manipulating the browser session, which is the other half of uBlock’s functionality and why it will always be superior to PiHoles or ad-blocking DNS.
Google, for example, smuggles ads through their “good” domains on YouTube that deliver video content; at that point, it’s an endless game of whack-a-mole in the dark to have a list that filters the correct URL without obliterating the ability to watch videos.
URL filtering is better than nothing, but it’s not really a comparable solution.
Unless by built in, you mean the ublock that comes with librewolf, thats fucking stupid. Adblocking is an armsrace that requires constant up to date collaboration on the adblock developer side. Thats why you need crossplatform plugins like ublock, otherwise you will end up seeing ads.
Vivaldi browser also has a built-in ad blocker on all platforms, but the PC/Mac/Linux version also allows you to use uBlock Origin as well (at least until mid-2025).
No, Vivaldi, Brave and Opera have builtin adblockers which don’t depend on the extensions manifest. Plus, one could always rely on AdGuard, which whould block ads system wide.
I’ve done tests with the built-in Firefox strict mode vs uBlock and there’s a bit of a difference. Firefox blocks about two thirds, uBlock is almost 100%.
