Why doesn't New Tab command work? Or clicking + sign in tab bar?

I looked at the answer to the + sign not working. But could not understand what exactly was the solution. The File>New Tab command is the same as clicking the + sign. Neither work for me UNLESS I launch Firefox in "safe" mode (Option-click). I don't see why I have to remember Option-click every time I open Firefox.

I'm on a Mac mini (new in March 2014) with Mac OS X 10.9.4, Mavericks. Is that the problem?

The answers I've read here use terminology I do not understand. (I made a living writing computer manuals for HP and Apple, so I'm not naive.) Do you have a glossary somewhere?

I just want to be able to open multiple tabs in one window and click from one to another. I used to be able to do that.

We have seen reports about a Community Toolbar extension causing this issue with not being able to open a new tab. Your System Details list shows:

  • WiseConvert Community Toolbar

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

The link to https://support.mozilla.org/kb/Troubleshooting+extensions+and+themes

got me to instructions for troubleshooting hardware acceleration. I turned off hardware acceleration and Quit Firefox. Then restarted as normal (not safe), and the New Tab command works again! Thank you!

I did this … Switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance … without starting in Safe Mode, and now I do not even have the default mode listed as an option. So now I have simple gray mode, but still the tab thing does not work. I am on newest MacMini with 10.10 .. and the new tab thing does not work .. keyboard combo, + tab, or menu bar.
