I use the "Larger text" Display Zoom option on my iPhone. Until recently, the tab view in my Firefox app would show my open tabs arranged in two columns. But yesterday, it suddenly began showing my open tabs arranged in a single column, with each tab preview so large that it takes up half of my iPhone screen. So I can only preview a couple open tabs at a time, and I have to scroll through my open tabs vertically. This makes the tab view much less useful.

How can I change the tab view to once again arrange my open tabs in two columns instead of one while in iPhone's "Larger Text" Display Zoom mode? If I change it to the "Default" Display Zoom mode, then the tab previews are arranged in two columns as usual.
