Links not opening
I'm using an iMac with OS X El Capitan 10.11.6. I am using Firefox 78.15. When I click on links, nothing happens. I have to right click and select "open link in new tab." I suspected it might be an out-of-date Add-On. So, I disabled all add-ons and restarted Firefox. It had no effect.
This problem is getting annoying Any assistance is greatly appreciated.
It's not just one site. It's all links. I can only open links by right clicking and opening in a new tab.
