Crashing site error for Mozilla Firefox browsers on Desktop

Hello! I whish to show you a certain crashing error that appears since yesterday.  For Mozilla browsers using Windows 11 on Dell laptop. 

Error code 520

Now, I just downloaded Opera browser, here everything works. I can't seem to load the screenshot.

That helps. Was too much cache memory. Will try to remember this trick next time. Happy New Year!

 Ji-N:

I'm not sure whats the issue. if it does happen again, please let me know.

Ok, sure. Maybe someday you'll find the right answer. Until then a refresh or two doesn't hurt. :))
