I'm not sure why the mirror function nor the 180 rotate function doesn't work for me. All it shows is a black screen. All the other rotations and buttons work. Since the creator seems very responsive I'm hoping they can fix this (sorry it's a bad review I don't know where else to contact). Thank you!
2023/02/19 HI. i have checked. It still works normally, both the mirror and rotate buttons. Or do you mean the shortcut doesn't work? maybe some addon use the same shortcuts How to Manage extension shortcuts >>> https://support.mozilla.org/en-US/kb/manage-extension-shortcuts-firefox
if it's still not work. Can you try disabling all addons to just this one? If it works, it means some of your addons are in conflict with this one.
If it works then please reply me. I want to know which addon it is so I can check and fix it.
