STG doesn't work anymore with firefox 119 on mac

I experience similar behavior with firefox 119 on ubuntu. Besides the spinning wheel when opening the extension, there also don't seem to be right-click options to e.g. send a tab to a different group.

Same thing for me. The extension on FF 119 on MacOS doesn't work at all.

I've periodically gotten this error on Firefox 115 recently. If I close Firefox and restart it, I'm able to use STG again, but in some cases Firefox will hang during shutdown. My only resolution was to force quit Firefox. When that happens though my previously opened tabs may not show up again when Firefox is reopened.

Same bug on Firefox 119, Archlinux. Note that deactivating and reactivating the extension on the add-ons manager menu makes it works again (until Firefox is restarted)
