A terrific free, useful, intuitive and unobtrusive add-on -- a great productivity tool which should be in the "Recommended extensions" category!

I have been happily using this in it's most basic mode ("Native highlighting") for quite a while before reviewing its options today following the update to v2.3 and "discovering" the "Custom highlighting" features of multiple highlights in different/selectable colors, and the scroll bar search/location markers -- yet more elegantly-implemented genius!

However, there is no obvious way to contribute to the author so as to fund the awarding of (at least) the "Verified extensions" designation (read the caution in the title's summary description "This add-on is not actively monitored for security by Mozilla. Make sure you trust it before installing. Learn more"). See "Add-on Badges -- Firefox Help" at https://support.mozilla.org/en-US/kb/add-on-badges

I hope he knows I'm grateful for this "gift".

A Bug：After select and copy, the text that copy will missing some word at the end

Superb addon, especially the clickable markers is such an useful feature. If possible, I'd love to be able to change the text color of secondary hits in Custom Mode to white (resembling the behavior in Native Mode).

Also, there is a very minor 'bug', in that when you click the page to turn off the highlights, the primary hit very briefly flashes color to that of a secondary hit before actually disappearing, instead of disappearing right away. It's so insignificant that it might not even be considered a bug, but i thought i should let you know anyway.

Thank you again for this amazing addon

Dear Dev, can you add an option in extension to skip the selection when only one or two empty spaces are selected? It just highlights the whole page spaces at once. and maybe change the default pink color to yellow or something

Is this open source? Where can I see the code?

After the re installation, it returned to normal.
It's still the best highlight addon.

Doesn't work. Does absolutely nothing at all. Neither Native or Custom mode works. Firefox 79.

Congrats man, very useful!! Thank you.
It's only weird that it's not deterministic when the text will keep selected after highlighting, sometimes it will (and I can copy), sometimes it won't at all, and sometimes it looses it partially... So sometimes I'd like to disable the extension, but I cannot seem to easily do it!! There's two options: Always on, where the shortcut do not work at all, and Activate on shortcut, which makes it disabled by default! Could you please include a Disable on shortcut (to keep it enabled by default, but able to disable it), or just always enable shortcut?
I would also like to see its code open on github. Think about that.

This does exactly what I was hoping it would do. Thanks

Nice! I could make the experience a lot better if there was a toolbar icon to manage it, rather than going to the settings.
Also, it would be amazing if we could add custom words to highlight, instead of selecting text first.

It kind of works, but the scrollbar markers don't appear for all instances, don't do anything when clicked, and sometimes appear for instances that don't exist. I was hoping this would be useful, but given that my testing shows it's not reliable, probably better for me to uninstall than get unreliable results.

Would highlight sections or words I didn't have highlighted. Also found the "left click" to highlight very annoying. Would make more sense just to "right click" and select 'highlight selected word/text'. Uninstalled.

Can you make this work with Firefox's Control+F? So I don't need to click the word.

I just switched the default browser from Google Chrome to Firefox and have sought out the feature to display FIND research highlight in scrollbar and found this extension. I loved it. Keep up at good work!

It does what it says, and very well.
It would be even better if it did not require dangerous permissions (access your data for all websites)

This plugin is an essential in my toolbox. (Auto-highlight all, amazing for code reading.) With Firefox 75, it's back to working perfectly. Unfortunately had to survive for a few Firefox versions without it due to components in the browser breaking. Many thanks to the addon's author/maintainer for keeping this plugin going. He was a pleasure to interact with when I inquired about this now-past issue.

Хорошее дополнение, не хватает только Русского языка, не удобно настраивать методом тыка.

It works

Very nice idea and implementation of virtual scrollbar is outstanding.
NOTE:
Native highlighting is not working due to FF bug.
If anyone has Ctrl+F8 shortcut occupied, FF support shortcut changing in extensions settings.
@Jerome
Is it possible to implement search function(e.g. from toolbar, or preferably from context menu)? It would be highly useful. No other extension provide similar features.
