Manifest v3?

[lrq3000]

The extension cannot currently be installed through the Chrome store because it is using Manifest v2 (MV2), and Google recently changed the rules to block the installation of MV2 extensions.

There is currently no available MV3 sessions manager extension for Chrome, it would be amazing if yours could be compatible with MV3!

Sorry about my late response and thank you for using Project Tab Manager.
Unfortunately, due to lack of my capacity, I don't think I can continue maintaining this extension.
However, I released an alternative called Tab Group Manager. This is slightly different from PTM and keeps tab state persisted as bookmarks on the browser so you can always resume where you left off, and it's Manifest v3 (Though, it's not open source).

Hope this helps.

Thank you for your reply and transparency.

Any chance you may opensource the extension you link to? I am really looking for an opensource sessions manager so that i can rely on it long term, currently there are none for MV3 unfortunately.

Unfortunately, I couldn't get an approval from my employer for a reason I don't know about.
