Until today everything okay. This evening tried to re-open Firefox and it would not. Rebooted computer & Firefox opened OK but after I closed it an tried to reopen, it would not start. Now it appears that Firefox will only open on a fresh restart of my computer. Running W-7 64 bit.

Some added toolbar and anti-virus add-ons are known to cause Firefox issues. Disable All of them.

Start Firefox in Safe Mode {web Link} by holding down the <Shift (Mac Options) > key, and then starting Firefox. Is the problem still there?
