This add-on allows you to paste an URL or search from your clipboard (or primary selection, see below) by middle-clicking the new tab button (just like it’s possible in Chrome/Chromium).

Did you know that you do not have to explicitly copy text when you are using a Linux-based operating system (which uses X11) like Ubuntu or openSUSE? It is enough to select the text, and you can paste it by clicking the middle mouse button (or scroll wheel). Just try it after installing this extension: Would you like to know, what a “wampum” is? Just select the word by double clicking it, and then middle-click on the new tab button.

By the way, if you are a Linux user and you are missing this auto scroll thing when middle-clicking on a webpage, which is enabled by default in Firefox for other operating systems, go to about:config and change the value of general.autoScroll to true by double-clicking it.

This Firefox extension bases upon Paste Onto New Tab Button by Marien Zwart, which stopped working after an API change in Firefox 25. Since the patch I proposed in an add-on review in 2014 can no longer be easily applied with compulsory add-on signing and the contact information of the original author is out of date, I revived this add-on.
