Very nice, thank you!
Just some remarks:
- would it be possible to make it "multiple", so that we could have more than one shortcut?
- would it be possible to add the thumb of the webpage(s), or to get it directly? => so, out of the blue, I've just noticed that the icon has updated indeed... but not each time.

Thanks in advance!

Edit 10/10/2025: Sanitizing the URL saved in the options was not a very good move, because now the addon doesn't recognize the right URL and opens a new tab on every click... :/
