I'm not sure where to post this since it isn't a question. I normally keep a lot of tabs open on mobile Firefox, and recently updated to a new version which changed the design of the browser drastically. One thing it changed is the open tab viewer, which now opens from a window at the bottom of the screen. The problem is that when you start to scroll your finger down (so that you can view older tabs higher up) it pulls the whole tab viewer down and away. It is so annoying to use and has no real way to open scroll immediately. The closest thing I have found to a solution is opening the tab viewer, scrolling up (so the page goes down) so it bumps against the bottom of the page, then scroll down only while the scroll is visible. An easy solution for this is to make it require 2 fingers to close the tab viewer while over the tabs, or 1 finger when on the notch at the top.
