Forum zgromaźeństwa Firefox

Hi Folks, Recently I have been having an issue with accessing a particular website which is asus.com and the nature of the issue is as follows. Every time I attempt to login I receive the following error message.

The browser could not find the host server for the provided address.

   "Check the address for typing errors such as ww.example.com instead of www.example.com.
   If you are unable to load any pages, check your device’s data or Wi-Fi connection."

It should be noted that this is the only website that I am having this issue any and all assistance in resolving this extremely annoying issue will be greatly appreciated

I have pop up blockers set to allow pop up blockers, but ev en though they are turned on. Firefox will not allow pop up windows in the learning management software (D2L brightspace) used at my university.
