Are you used to being able to highlight text and have it instantly copied to the clipboard? Why not have this functionality in your browser as well?
This is a fork of https://addons.mozilla.org/en-US/firefox/addon/copy-on-select by late spyrosoft. See the version history on GitHub for information on what has changed since the fork.
Here are some cases which are difficult or outright impossible to handle for this add-on:
- Technically impossible:
Firefox user interface elements outside of the main web page (URL bar, dialogues, etc.)
Special Firefox pages (about:*
,view-source:*
), XML documents
Disabled input elements of a web page - Probably possible, probably not:
JavaScript-heavy web pages, in particular if they do funny things with the selection (https://docs.google.com)
Please consider opening an issue on the support site if you experience a web page where this add-on does not copy-on-select.
