Hello John,

Yes; please, take a look at the "WebExtension" sample.

Hi David, I looked at the WebExtension Sample. I built it and installed it on Chrome. The Version of Chrome that I am using is : Version 75.0.3770.100 (Official Build) (64-bit) When I clicked on the Icon for the Extension the menu appeared. However, when I clicked the buttons to set the background colour the background colour of the page that I am on did not change.

Hello John,

I need to investigate a bit more when possible, since the sample works as expected in all the browsers that I try, not only in Chrome. What I see now, is that, for some reason I can't understand, we can't use jQuery to change the browser's pages color (like the sample want to do).

I am not sure if it's a question of permissions or what, since I discover that removing the jQuery lines and place a couple of "alerts" in their place, the sample working as expected, that is, the WebExtension receive the messages that we send, and even we can receive a message from the WebExtension context.

Even more, if we try something like this: "document.body.style.fontSize = '150%';", we can see it working as expected, so, it's quite rare why jQuery is not allowed... or working as expected... and I want to take a look at this when possible, John.
