After recent upgrade, Firefox won't start. Just flickers once when I click on a link or on its icon.
My version is 32. "Best Solution" says click the upgrade button to get v34. But I can't do that if FF won't open. I have Mac OS 10.9.5

You can check if you can start Firefox in Safe Mode by holding down the Options key.
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
Safe Mode. Holding down the Option key then clicking the FF icon did not work. The effect was to close the other windows on my desktop. FF just flickered as before but did not start. I have switched to Safari as my default browser.
