Thanks to thoughtful people like this developer, I can get the idea "it would be nice to be able to highlight this," do a quick Google search and bam, there's a free extension with more features than I even need. Thanks!

Spent days highlighting my notes for the upcoming finals only to find out it didn't save ANY of the highlights. There is no save button so one would assume it got saved automatically, apparently it doesn't.

EDIT: After enabling an option to save automatically it worked.

>> UPDATE: Lowering from 5-stars to 4-stars
>> I think since 5.0 my setting for "Shortcuts - Choose a highlight method" is overwritten every time the add on updates. I want "Use shortcuts or context menu" but the default of "Show marker popup" is the default. I change it to Menu but after an add on update it goes back to Popup. This conflicts with another add on that has a highlighted text popup. So I have disabled Textmarker and hope this is fixed soon. This is still a great add on if you want the Popup option for highlights.

Fantastic add on! Just about perfect for highlighting within current Firefox. I have one issue that would make this 5-star add-on a 6-star: allow Custom Markers to appear under Customize Shortcuts. I want all my shortcuts to start with Alt but Customize Shortcuts does not show my Custom Markers. My desired end state is Markers for alt-1 alt-2 alt-3 alt-4 with alt-d as delete. With Textmarker 3.10.0, the alt- modifier can not be used with Custom Markers like alt-1 and alt-4. Note, the whole issue with having to use Alt- is because I use "Search for text when you start typing" which means just using 1, 2, 3, 4 for markers also causes the Firefox search to pop up for that number. One other feature would be nice: Textmarker right click pop-up option to delete all markers on current page. Anyway, awesome highlighter, easily the best option for Firefox webextensions, maybe the best Firefox hightlighter ever!

Great one!

Great addon !! Really love it, does the job perfectly and is very useful for my intensive reading.
The developer was also kind enough to quickly rectify a bug which was in conflict with my other add on :)
Simple yet powerful !

Addon works good, but I have realised that it is problematic while cooperating with text editor ecosystem for html that I used - the CKEditor. Whenever I was using it, I had to turn off the addon, because the textmarker adds 'tmui' tags which are problematic for the code.
