Really useful. Would like if it could highlight using RGBA colors instead of just RGB.

Nice and useful, thank you.
Lately I have a problem with 2 lists I have created for the same site (outlook web): I want to highlight some email objects with one color and other with another color, but it works only when I open a list, save it without any changes, and then all words are correctly highlighted. If I don't do this it doesn't work....
(I'd like to highlight also the number of mails received for a mail folder, but I wasn't able to create a rule for this, outlook site code seems too complicated for me!)
(I have last Firefox installed, 114.0.1)

I lost all my lists after import some lists from another pc. Please consider to develop a auto-backup or multi-list combining feature. Many thanks.

Awesome idea. But I'm experiencing an errors:
1. Some sites start to partially duplicate text blocks if it has highlighted words. Need to refresh the page to fix it (YouTube), but sometimes even refresh doesn't solve the problem (Facebook).
2. Almost all highlighted words have a vertical strip to their right and are underlined for some reason.
Win10, Firefox 83.0

Unfortunately, pastebin synchronization doesn't work

This is probably the best highlighting tool available for Firefox at the moment.

But the blacklist feature ("Never highlight on these sites") is not working. When I add any site to the list it stops the add-on of working on any site and blocks the access to the configuration. To fix it you have to purge the configuration (reinstalling).

Firefox 69.0.3 (64-bit) on Linux

I could not find the repo to try and create a PR.

Update: if somebody else is experiencing this issue; restarting the browser fixes the problem.

Import function does not work

This is an amazing addon for Firefox. The only thing missing is that it doesn't work with Firefox Android. Anyway to make this work?

This is probably the best highlighting tool available for Firefox at the moment. However, I can't seem to get the import/export functionality to work correctly.

When I hit export, I get a file with no file type associated with it, and importing that file does nothing. Tested with clean installs of the extension in Firefox.

Currently running:
Windows 10 (1903)
Firefox 68.0.2
Highlight This 4.7

Exactly what would I write:
"Been using this in Chrome for almost 3 years. And finally switched to Firefox. I love this tool!

*New update: May 14, 2019
Pastebin remote file sync do not work."

Please update :) this addon is marvelous
