Extensions and manifest 3

CummingCowGirl

I'm using the below email I received from the team at Simkl as an example. As you can see they are letting peeps know extensions on Manifest 2 will no longer be supported under Manifest 3 very soon. I would like to know how this is going to affect Vivaldi and extensions in it?

Chrome will disable all Manifest V2 extensions this month. Please update.

🚀 All Simkl's Chrome Extensions were completely rewritten to support the new Manifest V3.

We’re excited to announce that our Simkl Netflix & Crunchyroll Enhancer extension has just been updated!

To ensure you continue enjoying the best streaming experience, please download the latest version now at https://chromewebstore.google.com/detail/enhancer-for-netflix-crun/dbpjfmehfpcgmlpfnfilcnhbckmecmca.

What's New in v8:

Complete Rewrite for Manifest V3:
Rebuilt from scratch to support Manifest V3, ensuring the extension keeps working as Chrome phases out Manifest V2.
Extra Permission Checks:
After updating from v7, click the extension icon.
Open the settings popup.
Click the " Fix the extension permissions" button to upgrade to the new Chrome Manifest V3 permission model.
If you run into issues, toggle the Netflix or Crunchyroll export watch history to Simkl OFF and ON or hit the "Check Now" button to start the sync or Re-install the extension.
Netflix Profile Selection Fix:
Updated to align with Netflix's new HTML code.
Simkl and IMDB Ratings Fix:
Fixed display issues with Simkl and IMDB ratings.
Added ratings when opening a movie or show via direct link.
Updated IMDB icon to the new logo.
Crunchyroll User Profiles Support:
Added support for the new user profile selection feature.
Permissions Fix Button:
Implemented a detection system and a button to fix permissions after using browser cleaning tools.
How to Update:
Visit the extension store and download the latest version of the Simkl Netflix & Crunchyroll Enhancer extension (V8.0.2).
Follow the steps in the "Extra Permission Checks" section to ensure a smooth upgrade.

@CummingCowGirl This says support for manifest v2 will be maintained in Vivaldi. I take it that means extensions will break in Chrome, but not Vivaldi.

All extensions which can not be ported to Manifest v3 will stop working after June 2025. That is a fact.
You need to ask extension's author/support to get more information.

I understand that those users who did not apply the register policy, will see that the extensions that did not switch to MV3, will stop working between June 2024 and June 2025.

How soon?

Based on what criteria will this date occur?

Your country
What extension blocker you use
Sites you visit
How much do you use YT
????
etc.

Those who applied it will be "safe" until June 2025.

@barbudo2005 That image is only screenshot from the weird Chromium warning, not a extension block.
I ignore it.

If important extensions for my web development will not work in 1 year because of Manifestv3, i could try Mozilla as they support v2 and v3. A software tool has to work like hardware tool for a craftsman; I do not have my browser just for surfing around. And if Vivaldi fails, this will be the end of my relation to it. Sad, but that is my reality.

as said before, no fear. The extension dev has already updated their extension to MV3

What's New in v8 [...] Complete Rewrite for Manifest V3:

So if you have the latest version, or you'll get it soon, you have no issues.
That chromium message is not blocking (yet).
You'll see a disabled extension warning when it will, in such case (likely not before six months)
