Hello there. I'm using Mac OS Sierra 10.12.6

This morning I updated Firefox to the latest update and since then it stopped working. Whenever I click on the icon nothing happens.

A similar thing happened to Firefox Developer Edition a few months ago and since then I switched to the normal edition of Firefox.

I trie uninstalling and installing again. I tried deleting my profiles and making new profiles. I deleted all related files and installed Firefox again and nothing worked. This issue is for both versions of Firefox.

The only way I can get Firefox or Firefox Developer Edition to run is to run the profile manager, delete all existing profiles and create new one. After doing that Firefox will run, but if I close Firefox and open again it won't open.

Thanks in advance for the replies and suggestions. I hope I can find a solution soon. Life is hard without the Firefox Dev tools.
