Does not work in Firefox Developer Edition on Linux Mint

I am using the extension in the following browsers and it has not worked when I disable JavaScript. JavaScript is still enabled when the JavaScript toggle button shows JavaScript is off.

- Firefox 108.0.2 (64 Bit) on Linux Mint 21.1
- Firefox Developer Edition v109.0b9 (64 Bit) on Linux Mint 21.1

This has been the case for awhile. Not sure why but I thought I should open up an issue.
