Script No Longer Works on Firefox After Latest Update

[mrevtai]

Running Tampermonkey v4.13.616 on Firefox 91.0.1 on macOS Mojave.

After updating the script this week, it is no longer working. When I check Tampermonkey, it shows that the script is active on the page, but the phoenetic-semantic information is no longer displaying/loading on my lesson pages. Happens on both desktop and mobile (w/ Firefox Nightly for add-on support).

Is this a known issue? Any advice to troubleshoot?

Due to internal changes in WK, the script did not work anymore recently. I merged a pull request from @Sinyaven, which changes the way the script is hooking into the pages. I just tested it in Firefox on my Mac (Big Sur), it is working for me.
There was a long series of issues with TamperMonkey + Firefox with this script, Firefox likes to mess around with their security settings, breaking TM. Do you see anything related to your problem in the dev console (⌥+⌘+i → Console)?
