Google search results won't open in a new window
I like to have Google search results open in a new tab and, until recently, using Google's settings allowed me to do that. But now if I click a lik in search results, it opens the page in the same window. In other words, FF "refuses" to obey Google's preferences.

Firefox should divert the new window to a new tab when you check this box in Google's Search Settings:
"Open search results in a new browser window"
I can't think of any reason for Firefox to divert a new window back into the same tab.
In case one of your add-ons is the culprit, could you try Firefox's Safe Mode?
First, I recommend backing up your Firefox settings in case something goes wrong. See Backing up your information. (You can copy your entire Firefox profile folder somewhere outside of the Mozilla folder.)
Next, restart Firefox using Help>Restart with Add-ons Disabled. Don't check any of the boxes in the Safe Mode dialog, just Continue in Safe Mode.
Does it make any difference?
I have tried with Add-ons disabled, and still no luck.
