Hello, I am experiencing an issue with Firefox where some websites display a message saying that the internet connection cannot be established and that I am offline, even though I am connected to the internet. My internet connection is working normally. Other websites load without problems, and the same websites also work correctly in other browsers such as Google Chrome. However, in Firefox certain sites do not load. For example, YouTube and YouTube Music show an error message indicating that I am offline. I have also noticed this issue on a few other websites. Because the same pages work normally in other browsers, it seems to be related specifically to Firefox. Could you please help me understand what might be causing this issue or how I can fix it? Thank you.
