Hello, is anyone else having the uMatrix addon's filter dialog not render in icecat versions newer than 60?
When I click on the umatrix icon it only shows the border of the dialog with everything transparent in the center. I'm using uMatrix 1.4.0 from: https://addons.mozilla.org/de/firefox/addon/umatrix/ and Icecat 68.7.0-guix0-preview1 everything works on 60.7.0-guix1 I tried some other version before and rolled back to 60.7, because it also had the bug. Also no problems in my distro's firefox 75. I also uninstalled and reinstalled the addons with no change seen.
