Perfect works like a charm🌀
1. Not works on sites like this:
https://addons.mozilla.org/ru/firefox
2. Tab ReTitle > Settings > SAVED TITLES:

If there are a lot of links, when I want to delete last link, for example: at the end then scroll automatically go up! There is inconvenience when deleting links from the end. You always need to scroll down, down, down, down like an idiot🥴.

NOTE:
If you add feature for changing the favicon it would be great👌
