Why doesn't clicking on "+ Open a New Tab" open a new tab?
Clicking on the plus sign at the top of the page at the right end of the open tabs used to open a new tab. It doesn't anymore. How do I open new tabs????

Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).
- Do NOT click the Reset button on the Safe Mode start window.
Turns out it was the "Ask Toolbar" extension that was causing the proble. Thanks!
