User Reviews
Pros
- The add-on works well and is great for automatic copying on select.
- It is considered a classic and essential add-on by some users.
- Updates are still provided despite the original author having passed away.
- Some users find it compatible with recent Firefox versions like Firefox 84 and Windows 10.
Cons
- The add-on often does not work at all for some users or on certain platforms (e.g., 32bit Debian).
- It does not function properly on sites with content inside frames.
- The highlight of selected text sometimes becomes invisible after updates on Windows 10/Firefox.
- Lack of customization options, such as disabling auto-copy in text fields or options for copy delay and removing spaces.
- The add-on is old and there are better alternatives available now.

Great add-on, one of a kind, and works great, even though the author has sadly passed away.

Thank you.
If this extension doesn't work for you, don't rant complaints here - the author has died. You may want to switch to "Copy On Select 2" by "farblos".
Yes, the extension HAS been updated since then, but those are automatic updates by Mozilla (like "1.1resigned1"), which don't change functionality.

Add a popup which says ''COPIED!" because now I am not sure when the app is copying or not. There is an extension for Edge called Auto Copy (Developer: Jamie Hill) which shows the popup at the right bottom of my screen, with the words ''Auto copied!''. Please? And thank you for your long work for the last 5 years.

Is Copy On Select Safe?
Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.
Copy On Select requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.
