What happened?

Some Mozilla add-ons GUIs are not loaded when the add-on is opened, and it only shows the background color of the GUI. The add-ons which aren't working are: notion web clipper, windscribe, uBlock Origin. This problem was there for a long time and I thought that updating it will solve the problem. Here are some images that may help clarify the situation.

This is what happens after opening windscribe.

and this is what happens with notion web clipper

What about notion and windscribe? And yes, I am using Fedora 41 KDE with Wayland.

Same issue for me, happens for all extensions. I use the latest zen beta, on hyprland. It sounds like restarting the browser fixes the issue for few minutes (e.g., I am able to open proton pass), but soon after extensions are blank as on screenshots

I notice this only happens when the single toolbar mode is selected. They work fine with the other toolbar modes.

I will add to this, Running Arch, Gnome Wayland. Not all extensions behave this way but some(Firefox Relay, Web Archives) do.

Same for me. Arch, Hyprland.

How can I change the toolbar mode ?

Settings -> Look and Feel -> Browser Layout. I am using Multiple Toolbars. Top toolbar might look a bit goofy when switching from Single Toolbar mode. Restarting browser should fix it.

Yes, it worked this way for me. So the problem is with the single toolbar mode.
