Performance is bad, user interface is bad in last 79 fenix
Previous(old stable) 78 version was much better than fenix
my IMHO
This is not how giving feedback works. If you have performance problems describe the problem and give the developers steps to reproduce and information about your device and Android version. If you don't like the user interface make proposals so they know what they should improve. But be respectful to the developers and please describe only one problem per issue.
What @cadeyrn said. We are open to feedback, bugs, and feature requests. Please open individual tickets about specific performance issues with your configuration or which pain points you're having with the UX if you would like to help improve the app, but keep in mind we will not be responding to this tickets with attitude like this.
