Easy to use and does exactly what I expected it to do, marks text, no fuss, no complications. The fact that it doesn't save the markings is an advantage most of the time, because I don't have to worry about forgetting clearing Pages that I'll probably never visit again (what would surely clutter browser memory uselessly.) When I need to keep something, I do the obvious, I copy the text to a file, which I can access off-line any time.

I like the design of adding tiny flags beside the scroll bar.
However, it would be better if this add-on saves the marks.

The best highlighter add-on I've seen so far. It's not save-able (maybe a future option?) but it's great for one-time use, to keep my place on a long page when I come back to it.

Der Textmarker funktioniert einwandfrei. Lediglich die Farben müssen bei Bedarf in den Einstellungen freigeschaltet werden. Dies könnte auch per default vom Entwickler aktiviert werden (non-default Settings: "Chose color for highlighting in the Context Menu.").

Perfectly working and very useful.
Thanks mate.

Nearly perfect. Does exactly what you expect. Highlight text, pick a color, done. Even the side arrows are clickable to take you right back to the highlight on the page. Fantastic. If I could make a feature request that would make it perfect. When I'm highlighting and release the mouse button, a small popup near the mouse that just shows the colors would be a huge time saver for documents that I want to put many highlights in before screenshots. Thank you.

Great!
How to self-assign the Hotkey for highlighting: see bottom of linked page

For archiving, the highlights ARE PRESERVED if saving a local copy of the page with "Save Page WE" add-on.

One request: being able to assign a keyboard shortcut for highlighting myself.

Perfect. Even better than the version for pre-Quantum. It does what it's supposed to, and the only one of its kind.

Please don't stop updating this for future Firefox versions.

Very good! Especially because it does not save the highlights, which is something I do not need.

I only wish the colors would be a bit stronger, like a real text marker.

FINALLY! I've found a highlighter add-on w/ lots of neat features.

AMAZING WORK @ Developer

Works good.

To solve the F9 issue until the next update, you can disable the reader view: open the about:config page via the location/address bar. Click "I'll be careful" to continue. And set "reader.parse-on-load.enabled" to false.
