As of 20191107215315 (actually the FF build prior), this is no longer an issue.
(Separately, I had the odd issue where NoScript was [totally] ineffectual.
Icon was there, no dropdown - at all, & no blocking.
Now I did cheat, but if you can't cheat, then it's not worth it.
Instead of "installing" NoScript [11.0.8rc1], I copied the .xpi into the /extensions/ directory, then renamed it to ...3232}, overwriting the existing, older NoScript .xpi.
[FF was closed, of course.]
Don't know if that contributed to the issue or what.
[That is not anything atypical for me - to "install" extension updates, that way.]
Another user with the same issue, Firefox 70.0/70.0.1 somenow breaks all addons
