Unfortunately does not work on my Firefox 93 on Windows 10.

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.

This can be considered the "official" extension of this feature. Read the publications of the autor.
It's working at least in Firefox 92b9

No longer working on Firefox 90. Link works once, and then won't work again if the browser has been closed and reopened.

great extension! Simple interact and useful for sending highlight parts. Expecting Firefox-mobile-compatible update.

I have always longed for the link to text fragment feature of Chrome. Thanks to the developer for it making it possible on Firefox :)

if it has an optional feature why you enforce it? "This is to optionally add a polyfill for the Text Fragment feature" still you cannot choose cancel or the extension will nor work, so it is NOT optional

In Firefox 81.0.2 the transition to the selected text does not work, especially with backlighting, just opens a web site by link, maybe what I do wrong? Cent Browser also does not work...

P.S. Already working, but with short words do not always get a link. Thank you!

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

Very good! The only thing I could complain about is the fact that we need to click "Copy Link to Selected Text" twice to successfully create the link. But works very well and I really recommend it.
