Multi Find: Search, Highlight, Explore by Vincent Greco

Multi Find allows you to smoothly search and highlight fragments, words or phrases within any webpage.

Multi Find is Unicode-friendly: it can handle non-English characters (Chinese, Japanese etc.) and special symbols. You can also turn on and off case or diacritic sensitiveness. It works on iframes and dynamically loaded content (regular webpage but also blogs, forums and even video subtitles).

What you see in the input box is what you get in the webpage, as the input box is formatted exactly like the result of the highlighting. An addition, the list of words can be manipulated through a toolbar.

Other notable features of Multi Find:
- Four ways to fill the input box: by directly typing into it, by copying and pasting, by loading a text file or by selecting a word on the webpage and using the contextual menu (right-click).
- Persistant list of words across different tabs, browser windows, and future sessions (local storage only, nothing is in the cloud)
- Number of occurrences for each searched word and the total count
- Navigation buttons to scroll through the occurrences of highlighted words
- Scrollbar marks to easily locate the highlighted words within the page
- Full customization of the interface (including dark theme) through persistent settings.
