From some days I am experiencing this strange problem in Firefox.
i am unable to open some sites with the "http://" address in Firefox
it don't shows any error message or anything just a blank page.
but if i edit there url to "https://" sites open normally.
this is really annoying. please someone suggest a solution.
Do you have the https everywhere add-on installed in Firefox? If so, disable and/or remove it and restart the browser to see if it fixes the problem.
Do the certain http sites work sometimes, and not others? Or is the behavior the same always at those sites? Try running FF in it's Safe Mode and see if the behavior continues

Thanx for replying.
It is the same behavior for those sites. other sites works normally.
and I've also tried safe mode but it's still not working.
