[BUG]?!

https://github.com/gorhill/uMatrix/releases/tag/1.1.4 - FF and webext versions.

afaik the developer dropped the xpcom version 1.1.4 will be the last xpcom build maybe you installed the beta version
install the xpcom and disable auto update (and maybe set the xpi to read only to prevent future updates to webext I did this for the mega addon)

edit currently the latest version is 1.1.12 and it's webext only
until webext support lands in basilisk you should downgrade to 1.1.4 and set the xpi to read-only you can find it in your basilisk profile

Basilisk supports WebExtensions (experimental, but still, any normal WE that is reasonably cross-browser should work just fine). You could read the features page, you know.
