Firefox: MultiCopy is a simple Firefox add-on that allows you to copy multiple chunks of text sequentially, thanks to a now extended clipboard memory, and then paste that text in the order you copied it.
If you work within Firefox with text a lot it’s a big time time saver. You can easily toggle the feature on and off from the right context menu. To use the add-on you simply copy and paste within Firefox, no special menu or keyboard commands required. The biggest limitation is that it only works within Firefox (it doesn’t extend the system wide clipboard at all).
MultiCopy is free and works wherever Firefox does. Have a better clipboard manager either for Firefox or your greater OS of choice? Let’s hear about it in the comments.
