Firefox Receives Search Highlights in Scrollbar

And you can change the Search Highlight Color in Scrollbar in Firefox.

Mozilla has added a nifty search enhancement to Firefox 87. The Highlight all option in the Find dialog to show all matches with their relative page position in the scrollbar. The entries appear as colorful lines over the scroll position.


Such a feature already exists in Google Chrome for some time. Now Mozilla is adding the same to the Firefox browser. As of this writing, you can test how it works by installing Nightly.

Once you do that, Firefox will highlight all the matches on the page with a color. Additionally, the match positions will appear in the scrollbar area. The implementation reminds of how text diff tools mark the text changes, e.g. WinMerge.

The new text match indicator is definitely a useful feature when you are searching through a lengthy web page. In the future, Mozilla is about to add a GUI option that will allow customizing the highlight color. Currently, it can be done in about:config.
