Ok cool to change without going into about:config

BUT,
am searching for a even more accessible settings.. by clicking a button in my toolbar !
Thanks

working fine but:
- you need to restart to use this extension, no notification to restart firefox.
- no icon in firefox toolbar, pretty difficult to use.
sorry, uninstall it

Please add an option that makes these new tabs to be opened in background.

Opens some links in new tabs, but not all (even after selecting the option to open all links in tabs)
