Re: firefox query

Yeah, to open a link in a new tab, I believe you can simply
middle-click it (hopefully you have a middle-button, or a wheel that
you can press down). You can also middle-click to close a tab,
middle-click the tab bar to create a blank tab, and double-click in
the tab-bar to undo a tab close!

Also, I recommend getting the Tabbrowser Extension -- once it is
installed, you can set the following in Tab > Tabbrowser Extension
Preferences:

Advanced > Window Mode > Use One Browser Always

Startup and New > Open New Tab At > Rightside Of The Current Tab

Focus > Load New Tab In The Background When It Is Opened By > Links
With Middle-Click
