I've been using Firefox for some time on iOS. Some websites cause the user interface to become hijacked by the website. What happens is I can't scroll up to the address bar or down to the tabs and menus. All I see is the website in full screen. Two awkward workarounds exist: I can exit the application by swiping up from the bottom of the screen, then re-entering Firefox. Alternatively, I can slow-swipe up from the bottom and then tabs/menus usually appear when I let go. I attached two images, one shows the Wired.com website in this hijacked state. The other shows the application after I have exited and reopened it. This happens on many websites and I would say most of the time it occurs where there is some sort of popup/overlay that appears in the JavaScript. iOS 18.0.1, Firefox version 131.4/
