Hi, i recently have a issue, where most of the addons don't show the content of their defined popup. I do the following sequence. - open firefox - add a addon - add it to the toolbar - click on the icon to access its popup The popup is then opened and the outline of it's size is most likely correctly calculated, but the content is missing. The reference Addons are passff, with no Content SakaKey, with an partial rendering HTTPSEverywhere, with the full content and the expected behaviour. I tried to reset the browser via the about:support page, no change. I restarted in safe mode. That was kind of pointless, because without addons, there are no icons to click at^^. I created a fresh profile, also no change. So i downloaded the latest nightly, started with a fresh profile, and installed one addon, still not working. I fickled with the browser-style property in the manifest.json of passff, and set it to true, but again it still shows no content. What is most likely missing on the shared data, i run Ubuntu 20.04 with i3 as a window manager. Has anyone a idea what i am missing?
