Firefox keeps opening things in new windows


Every time I click to open something in a new tab, it opens in a new window instead. I checked to see if I'd accidentally changed my options to make things open in new windows instead of tabs, but I hadn't. Also, every time I start Firefox, three windows pop up instead of just one. They seem like little things, but it's really irritating.

Hi Fantasmically,

You might want to take a look at Firefox repeatedly opens empty tabs or windows after you click on a link. It seems to be spot on for the issue you are describing.

You might also want to try starting Firefox in Troubleshoot Firefox issues using Safe Mode. If you don't have the issue while all of your add-ons, extensions, and themes are disabled, you can try adding them back in one by one until you find the culprit. You should look at the Extensions and Themes troubleshooting guide and the Troubleshoot issues with plugins like Flash or Java to fix common Firefox problems article as well.

Hopefully this helps!
