Its great add-on.
Can we have color customization for highlights? would be good addition here.

Helpful in research, especially when you are looking for specific information.

Feature Request:
It would be much more research friendly if it has an option to highlight any number in text.

En Firefox 88 no funciona.

this works if you separate words with comma

πολυ καλο

doesn1 work

This add-on is very effective to block the news offer company which seems to be doubtful.

работает как написано но глючит, крошит браузер, подвешивает

yep. probably the best highlight tool for firefox. simple and feature-rich (for highlighting).
has (like desc says: ten colors) ten colors enough for most people, it highlights letters not words (eg: give highlights given [you'd be surprised, some addons highlight only whole word or use asterisk modifier to highlight everything) and the option "make highlight more subtle" is awesome too.

I love this Firefox Add-on (I use it daily). I was wondering, can I use a shortcut key (like CTRL+H or another combination that I can pick myself) that will toggle the highlight on and off on a web page? If that is not possible now, will the author please consider adding a shortcut key to turn highlighting on and off? Thank you!

Не работает.

Works as expected (FF68, Linux), but two features are missing:
1. keyword list per page/domain;
2. "Reset" button (otherwise you have to clear the list and refresh all affected pages.

This is the only add-on I can find which supports MULTI-keywords! Perfect!

Will be better if it can configure keywords per website (per domain).

GOOD TOOL, HOWEVER CRASHES EVERYTIME...PLEASE FIX
