It used to work well, But the addon doesn't work in the latest version of firefox (88.0.1)

I'm curious to watch the development of this very interesting extension. Thanks Haru!

I just installed this and it's great.
I've always used Firefox
but I switched to Chrome a couple of weeks ago
because I could no longer use the SearchWP addon in Quantum.
I didn't want to keep using pre Quantum versions and I didn't really like Waterfox.
I found a pretty good alternative in Chrome, Highlight This!, but I just don't like Chrome.
'Search and Highlight' brought me back to Firefox.
You can highlight everything:
single letters or numbers or grammar symbols, part of a word, complete word, hyperlink word.
I didn't see a PayPal Donate link but if this ends up being reliable and stable I want to donate.
My only complaint so far is that you have to click the Search button on the addon every time you refresh a page, go to another page, or expand the page(ie Show More Comments). A hotkey shortcut for the Search button would be good but even better just keep the highlights on until you decide to disable them. That would require another button or a toggle function.
