What's your computer system and Firefox version?

I've tried opening in safe mode and refreshing Firefox but none worked.

Start your Computer in safe mode with network support. Then start Firefox. Try Secure websites. Is the problem still there?

Please note that I am having this problem on several computers not just on a single one, also I can tell it is not a internet issue since other browsers are working perfectly. Also please note that I am working Windows PC's not Linux.

I'll try what you've said and i'll update you with results.

Thank you.

I've tried doing that, the same problem persists

Did the problem start with the current Firefox, or what?

Firefox safe mode no help. Computer safe mode no help.

Many have reported issues using the 64bit Firefox. Install the 32bit version from; Download Firefox For All languages And Systems {web link}

Apparently switching to 32-bit version solved the problem, I'll try it for a couple of days and update you with the results.

thank you for your support.

Glad to help. Safe Surfing.

Hmm. What do I lose in performance and features if I decide to switch to the 32-bit version? Is it easy enough to go back to 32-Bit without any 'nightmare' install problems?

I am not sure. You could post a new question asking.
