Middle Mouse Button Opens Link In TWO Tabs

Recently, firefox started opening two identical tabs on middle mouse click instead of one. This behavior is not consistent, but happens more often than not. I already checked if the mouse is not faulty and submitting two clicks instead of one, but it is not. Also trying Chrome and Edge, both work fine, and only firefox does this.

I am running FF Dev edition v93.0b9 (64-bit)

Any tips are appreciated, and while I know this has been asked before, that question came in 2014 and was supposedly fixed by an update.

Start Firefox in Troubleshoot Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration or userChrome.css is causing the problem.

  • switch to the DEFAULT theme: "3-bar" menu button or Tools -> Add-ons -> Themes
  • do NOT click the "Refresh Firefox" button on the Troubleshoot Mode start window
