What issue do you have?
When trying to use the Web Clipper, I got the error "The Joplin extension is not available on this tab due to: Missing host permission for the tab". I tried closing and reloading Firefox, but I got the same error.
I searched the web and found the same error described here: The Joplin extension is not available on this tab due to: Missing host permission for the tab . This led me to the advice to look into the Firefox preferences. But this was not the issue, which was to be expected since this was happening on a lifekacker page. OTOH, I checked that at least two other extensions were locked too.
On a hunch, I decided to "clean" the address by removing everything after the first "&", then reloaded the page and bingo! Everything was working again. So this is not a Joplin issue, it is a Firefox problem. But if another user is locked like me, this is a workaround.
