The latest release of Firefox is 33.0.2. Is that site that picky about the encryption, and did the encryption setup for Firefox change that much between 33.0 and 33.0.2?

Some web sites do not like Firefox. Two things to try;

• 1

Start Firefox in Safe Mode {web link} While you are in safe mode;

Type about:preferences#advanced<Enter> in the address bar.

Under Advanced, Select General. Look for and turn off Use Hardware Acceleration.

Poke around safe web sites. Are there any problems?

Then restart.
