Hi misspril, in the Google preferences ([https://www.google.com/preferences]), the checkbox is labeled [x] "Open each selected result in a new browser window" What that does is add code to each link to direct Firefox to open it in a new window instead of replacing the results page. Once you turn that on, the normal Firefox setting on the Options/Preferences page -- [x] "Open links in tabs ''instead of'' new windows" -- should divert each new window to a new tab instead. Does that combination of settings work for you? ''What about sites where the links are not coded to open in a new window?'' Firefox does not have a general setting to send ALL links to a new tab. Instead, it has the option to divert new windows to new tabs instead. If you want to send ALL links to a new tab, you can use an add-on like the following to modify the links in each page: https://addons.mozilla.org/firefox/addon/open-link-with-new-tab/ Does that help?
