The multi tab feature, however, does raise the question of whether Firefox Focus will remain relevant in the long run if Mozilla keeps adding features that can be found in the regular Firefox browser anyway. Mozilla hasn’t yet mentioned any such feature for the iOS version of Firefox Focus. Due to popular demand, or so Mozilla claims, the browser now supports multiple tab browsing instead of forcing users to just one, extremely safe and private tab. That is changing a bit for the latest version of Firefox Focus on Android. The more tabs you have open, the more memory and processor power you're using. The delay in switching between tabs could just be due to the limitations of the machine. Mozilla does already have a privacy-centric version of Firefox, one that extolls the values of simplicity and privacy. What I don't understand is Firefox being sluggish in switching tabs while Chrome doesn't. Presuming, of course, they’re running on iOS 11 already. Fortunately, Apple has somewhat relaxed those rules in iOS 11 so Firefox users can now enjoy tracking protection options on regular browsing as well as ad and content blocking in private browsing. Those same rules also prevented Mozilla from implementing key features that desktop and Android users have already been enjoying: tracking protection. Mozilla was eventually able to work around that, but not without some cost to its mobile market share.

Apple has very stringent rules when it comes to iOS apps, and one of those was the use of the WebKit web engine in third-party browsers. If I open up a new window it always opens up these 4 tabs. Firefox’s long absence from one of the world’s biggest mobile platforms was, to be fair, no fault of its own. Question - I have FireFox setup that when I launch it, it open 4 tabs and opens 4 different sites.
