A few days ago, the userscript stopped working in Mozilla Firefox (128.0) + TamperMonkey (5.1.1). I've managed to locate the problem in the livequery library, which seems to not be working anymore. Therefore, the code for insertion into editor (m_toolbar.user.js:155) never gets called.

I suspect this might be due to a recent change in TamperMonkey in version 5.1.1, which mentions:
Since livequery library is used for detecting changes in DOM structure, this change sounds like a plausible explanation.
If I use a different livequery library, the script works again.
Unrelated, another user confirmed that the script stopped working also in Chrome.
