how do I open firefox
I needed to ask question to register
Additional System Details
- User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/42.0.2311.135 Safari/537.36 Edge/12.10240
Not very sure what you mean, if you want to use Firefox on your iOS device, install it from the App Store and launch it from the icon created on your home screen.
If you mean you have trouble opening up the Firefox app (direct crash after launching, or force closes after launching, etc), try updating your iOS version.
Hope this helps :)
