I'm a long time Firefox user - - - on Windows. I was just given an iPad 2 with iOS 9.3.5 (13G56). I'm not a fan of Safari and would like to install Firefox (and sync bookmarks, etc with my Windows 10 machine). I found "Firefox: Private Safe Browser" in the App Store on the iPad 2, but when I try to install it, I get a popup message that says "Firefox: Private Safe Browser" is not compatible with this iPad. Is there a version that IS compatible? If so, how would I get it onto the iPad and how would I install it? Thanks, Jack
