Scrollbar Search Highlighter is a web-based application that allows users to quickly and easily highlight any text on webpages they are viewing. It is a useful tool for researchers, bloggers, journalists, and anyone who needs to quickly search, highlight, and copy text from webpages. The app has a simple user-interface and uses a simple drag-and-drop technique for highlighting text. It also has an advanced search feature which allows users to search for specific phrases or words and then easily highlight them with one click. Additionally, it allows users to save their highlighted text to their computer or mobile device for later reference.
Discontinued The add-on will no longer receive updates and will stop working next November with Firefox 57, when XUL-based add-ons will be deprecated in favor of the WebExtensions API. See http://fasezero.com/. The extension still works in XUL-based Firefox forks such as https://alternativeapp.info/software/waterfox/.
