How do i remove the red dotted border around links?

more options

On several websites (Facebook, Twitter, Hootsuite, etc) any link is outlined by a red dotted border. I don't know if I inadvertently changed a setting but it never was like this before and I can't figure out how to disable the dotted border from showing.

Any help?

Could it be a feature of one of your add-ons? You could test in Firefox's Safe Mode? That's a standard diagnostic tool to bypass interference by extensions (and some custom settings). More info: Diagnose Firefox issues using Troubleshoot Mode.

You can restart Firefox in Safe Mode using

Help > Restart with Add-ons Disabled

In the dialog, click "Start in Safe Mode" (not Reset)

Any difference?

Firefox's Safe Mode also would bypass any userContent.css file you might have created to apply style rules to websites. But if you don't recall ever doing that, then that's probably not relevant.

There are browser.display.focus* prefs that you can check on the about:config page to see if the have the default value.

Thanks for the replies. After restarting in Safe Mode, the red border was gone so I disabled the add ons that I never really use and restarted. Now the red border is gone so one of the add ons was the culprit.
