Fairly useless until this is fixed as reported by other commenter(s):
> after install I have to use "Copy Link to Selected Text" in context menu once to give it the permissions (why doesn't it request them directly on install?). And then also after every Firefox restart use that feature (even though permissions are granted already).

Works, it just literally takes about 30 seconds for it to jump to the right section while using Firefox.

But if I past the link into Chrome, it jumps to it immediately.

Not sure who's fault this is, but either way, it's annoying.

Bugs.
Similarly to review 1591337, after install I have to use "Copy Link to Selected Text" in context menu once to give it the permissions (why doesn't it request them directly on install?). And then also after every Firefox restart use that feature (even though permissions are granted already). Otherwise, add-on won't scroll and highlight the text fragment described in the URL.

Not saved after restart: "browser will scroll the selected text". In Opera, the link created in Firefox "works" after restart.
