Loupe автор scullionw

This extension highlights occurrences of selected word in page. Uses fast native webextension API and supports options such as case sensitivity or matching on entire words only.

Similar to Selection Highlighter (Chrome) or HighlightAll (FF).

Alternatives were broken since FF 71 or buggy in general, which prompted the development of this add-on. Functionality is basic but useful especially when reading code.
