Context Highlight is a Firefox Add-on that allows you to highlight all instances of a word that you have selected within the current web page.
I primarily built this as a quick research tool, to help users find key words within a web page quite rapidly. This goes beyond the standard Firefox highlight functionality by allowing matching on both words and phrases, and using different colours when multiple terms are highlighted.
How does it work?
Select some text text on the current web page, right click and then choose "Highlight Word" from the context menu (right click menu):
The text will now be highlighted, like so:
If you select several words, you can choose from the following options:
- Highlight Words - This will simply highlight all of the individual words, each in a different colour
- Highlight Phrase - This will highlight the whole selection (all the words will be treated as a single pattern which will be highlighted on the page).
To clear highlighting, simply right click anywhere on the page and choose "Clear Highlighting".
Ctrl when highlighting selected words or phrases to preserve any
current highlighting; i.e. the current highlights will not be cleared.
