Issue accessing Wikipedia in Private Browsing, but not otherwise

more options

1. Open Mozilla Firefox with Private Browsing enabled 2. Type en.wikipedia.org into the address bar Wikipedia doesn't show up properly for me. It shows a "Server Not Found" error message. I have tested other sites like Google and twitch.tv and they work. I have also tried typing en.wikipedia.org without private browsing and it works. Does anyone know why there's an issue?

hello Some_cheese_pause...

this problem phases only by you.... you have to firstly clear your cache memory and then search your website.


but after clearing cache memory...there is again an error message...then you delete the mozila firefox software and re-install it


Please give me feedback after doing these steps.

That's strange because you would expect regular windows and private windows to send requests to the same DNS service and receive identical address.

How do you start Firefox with Private Browsing enabled? Do you mean "automatic" private browsing ("Never remember history") or do you start Firefox normally and then open a private window (Ctrl+Shift+p)?

Do you use any add-ons that modify how Firefox connects, such as a VPN add-on?
