Should do this. Need to fix automatic release pipeline for chrome first. Also what about Firfox compatibility with v3?

Hi @fahad-israr @maxandersen i tried some changes in manifest and try to migrate from V2 to V3 using Mozilla migration for manifest Doc . I tested on my local machine, it didnot show error in both chrome and firefox.

But, in firefox,
the The developer preview of Manifest V3 is available after Firefox 101. Generally, it is not available for older versions, But can be done by turning on MV3 features, ie.

    Set extensions.manifestV3.enabled to true
    Set xpinstall.signatures.required to false

By default, these were true in my firefox. Steps to turn on MV3 feature

type about:config in firefox search bar and search the above mentioned options.

as it should provide according to line 32 in context.js

try if you can look for a workaround. Or else a meachnism to upgrade to V3 atleast for Chrome. Also, what version of chrome did you test it upon ? most people would already be upon chrome version released in last 6 months. would find very very few users using versions older than that ig.

I tested on Chrome, It worked as expected. I am still experimenting to make it work in firefox also. chrome version 'Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 Chrome/109.0.0.0 Safari/537.36' firefox version "Mozilla/5.0 (X11; Linux x86_64; rv:109.0) Gecko/20100101 Firefox/109.0"
