Dear support. a beginner's bug report... I'm using Firefox on my iPhone 4s with iOS 8.4, (jailbroken, using Firefox as main-browser with help of "Browser-changer") The firefox app is great and so much faster than the safari app on my device. therefore thanks. but... The private browsing is not available, although it's supposed to be, as the app description says. In the tab overview, there is no mask-Symbol and therefore I can't click on it. Well, I tried to find a hidden mask by just tapping anywhere, but without success. cheers, Mo
