I’m sure the intent was good, but somewhere down the road they failed miserably… A Ubuntu package called ubufox, or more recently xul-ext-ubufox breaks middle-mouse paste in Ubuntu/Kubuntu.
It claims to do this:
Integrates the browser with Ubuntu to: * Enable searching for missing plugins from Ubuntu software catalog * Add the following options to the Help menu - Get help on-line - Help translating Firefox - Ubuntu Release Notes * Set homepage to Ubuntu Start Page * Display a restart notification after upgrading Firefox * Add ask.com to the search engines.
But that’s not all, since middle-mouse paste gets broken too… Geez, thanks for making my life less convenient, and disabling what I’ve come to know as a Linux default behaviour for web browsers.
For some time I’ve wondered why I couldn’t activate this feature like described in this post. Turning the interest to my Firefox extension, I noticed I had an extension called Ubufox, which I couldn’t recall installing. So I googled it and came up with this link, revealing the horrible truth about this crap called Ubufox!
The solution is simple enough though, disable the Ubufox extension and then:
Aaahh, free at last!
