blank page

[ecilla]

why won't my blank page tabs close?

[johnpol78]

for closing the tabs in the firefox or the other web browsers.

click on red X button in the web page tab coloumn.

otherwise may be your computer should be infected by the viruses or malware .

so download the super anti spyware and anti malware bytes from the internet and scan the computer

after scanning the computer delete the detected items from the computer.
