Recently (a couple of months ago) a "standard" feature shared between Desktop and Mobile suddenly stopped working on my Android, and this cripples the use of many "secure" websites. We could click-and-hold, long-press, call-it-whatever, the Back button and instead of trying to go back one page Firefox would show a screenful of pages, like clicking the drop-down next to Back on the desktop version. I could click on the bottom link, then immediately hold again and go back another half screen, and in two clicks go back probably 70 pages. Why has this essential functionality been removed? How do we get it back? Can I roll back to a specific browser version just before it was removed? This function is so core to my effective use of Firefox that I would choose it over any notional "security" or "stability" enhancements from having a later version. Examples of why this is *not* a trivial problem-- On a banking or government logged in site, going back several pages (say, to before the login pages) is critical to continue reading the information you were reading when your session timed out (when the alternative is either try to click Back quickly several times but end up at the login page again, or spend half an hour following the obscure links to try to remember how you found the information in the first place). On a shopping site, having gone to the checkout and emptied your basket, if you need to go back and place a second order for things you've just been looking at but did put in your basket, it is critical to be able to go Back multiple pages to skip over the payment security screens, otherwise most shopping sites either hijack the Back button or get terribly confused whether you want to pay again or why it can't display the contents of your empty basket. On Google Translate, it's essential to be able to do this to flip back to previous translation attempts, because when you type text at the keypad the silly webpage takes every keypress as a new webpage in the stack, so you often have to go back 100 times just to get the previous successfully translated sentence.
