@dhowe This isn't unexpected. "Can't read and change data on this site", means that the extension doesn't have "host" (or site) permission, which would be needed to inject scripts into the site or manipulate requests to the server.

If you locate the page action, you can see the extension works:

The problem is not that specific message, but the fact that the addon is grayed-out, and has no pin option, so one cannot access the page-action, and thus cannot run the example. It is also the case for the 'borderify' example, even on mozilla.org for which it has permissions.

The examples site reads "Warning: Some examples work only on specific domains or pages. Details of any restrictions are provided in each example's readme file.", yet there is NO restriction mentioned in the applyCss or borderify READMEs, even though borderify appears as if it would only work on mozilla.org

If you look at the screenshot I added earlier the "page action" is the red circle icon in the address bar.

Again, there is no page action as it is disabled/grayed-out. I've updated the title to better reflect the issue

@dhowe the two extensions are grayed in the add-ons list because they don't have a browser action and therefore no toolbar button to "pin".
In the example screenshot in your last message you can see that borderify is working because there is a red border around the mozilla.org page.
What you will find is that you cannot used borderify and apply-css together - remove borderify, reload the page and the click the red circle icon in the address bar. It will apply a wider red margin to the page. (And if you open the extension setting you can also find options to allow it to work in private pages and the restricted pages.)

You're correct -- borderify seems to be working, though applyCss I still don't see any button in the address bar:

@dhowe in dark mode it appears to be a white circle

Got it, thanks
