This behaviour has been changed between the previous version i had (the one with linux mint 18.1) and the one i have now (xfce4-terminal 0.8.6 (Xfce 4.12)) When you're used to opening links with middle click in the terminal window, noticing that you just pasted 400 lines containing commands etc. is EXTREMELY ANNOYING, and could pose a serious threat to the user's system if ever he/she does so on a root term window. Please fix this ASAP.

Please fix this ASAP. Exactly, this is why the old behavior of opening URLs with a middle click was dangerous - missing the URL just a pixel would result in an undesired paste. And this is why the default shortcut for opening URLs was changed to Ctrl+click. However, you can always restore the dangerous behavior by setting MiscMiddleClickOpensUri=TRUE in your ~/.config/xfce4/terminal/terminalrc file. I have even exposed this setting to the Preferences dialog in version 0.8.7.0.
