Hi

What happens when you try to view that site on Firefox? Is there any error message?

I can't open FACEBOOK in FIREFOX.

no error message, nothing...

it just runs and nothing appears.. and the page is closed.

Do you have Bitdefender?

hello, yes i Have BITDEFENDER for a long time...and I never had this problem with Facebook via FIREFOX.

Users with Bitdefender security software installed may experience problems loading websites, particularly Facebook.com. We are working on a workaround, but as a temporary mitigation, disabling Bitdefender or turning off its traffic filtering features may resolve the issue.

hello,

I tried your solutions, but it does'nt resolve the issue...

Hey, I’ve seen this kind of issue before and it can be really annoying.

You’re basically saying Firefox is up-to-date on both your PCs, but Facebook just refuses to load/login, while Edge works fine. That usually points more toward a browser settings/cache or security conflict rather than Facebook itself.

I faced something similar a while back where Firefox suddenly stopped loading a few sites, and it turned out to be cookie + tracking protection messing things up.

What worked for me:

Clear cookies/cache specifically for Facebook Temporarily disable “Enhanced Tracking Protection” for that site Try Firefox in Safe Mode to rule out extensions Also check if any antivirus web shield is interfering

Not sure if it helps, but sometimes just removing saved Facebook login data fixes it instantly.

I usually just test things step by step and avoid reinstalling right away.

By the way, I had a similar discussion in Cookoutmenu community once, people had mixed fixes there too.

Did you try disabling extensions first, or it still happens even in Safe Mode?

You're using a less powerful model until your limit resets after 7:18 PM. Upgrade to get more access.

Upgrade

thank you for your help, but I tried all you recommended and the problem persists.. I think I will use Edge browser to have facebook site....

So, no one solution you proposed me was effective...but today, I can connct to Facebook with web browser Firefox... maybe it was a temporary problem..??

so thank you for your help
