Chrome Mv3 timeline update

[Libor Polčák]

Hello,

I noticed a small warning icon next to the JShelter item in Google Web Store 
which warns that MV2 extensions will soon not be supported. There is a link 
that leads to 
https://developer.chrome.com/docs/extensions/develop/migrate/what-is-mv3.

Notice, that the page says that MV2 Consumer Deprecation starts in June. But 
the meaning is not explained at that page.

Atter some clicking I got to 
https://developer.chrome.com/docs/extensions/develop/migrate/mv2-deprecation-timeline.
 The most important info:

* In June 2024, Google will start disabling Manifest V2 extensions in 
pre-stable versions of Chrome (Dev, Canary, and Beta).
* It looks like Chrome 127 will be affected. That means that on Jul 23, Mv3 
extension should be unavailable in stable Chromium/Chrome browsers 
(https://chromiumdash.appspot.com/schedule).
* Even if I am wrong and this will only affect Chrome/Chromium 128, that means 
stable release at Aug 20th.

Given the approaching holidays season and the badge icon deadline in June. I 
think we should think about releasing a broken MV3 version of JShetler soon. 
Maybe we can limit the version to a subset of functionality, maybe we can say 
that we do not guarantee that page scripts are applied. Or that Fingerprint 
detector works or what ever. But it looks like if we do not release a broken 
version, we will lose users anyway.

Looking at the NLNet project, we planed to rewrite with minimal viable porting 
in mind. Now we are there.

Best wishes

Libor
