Add "right of screen" for window content alignment

[joelberkeley]

Since the window is resized to avoid fingerprinting, I need to look at the cursor to select the scroll bar on the right hand side of the screen, as it's slightly offset. I'm used to being able to do it without looking because that's always where the scroll bar was.

Can we have an option to snap content to the right of the screen?

I mean these options

Are you maximizing your screen? If not, then your browser is windowed and there's no need to show the LBing matte - you can double-click the letterboxing area or matte (the area that is not the website/content) to snap the window size to fit the letterbox. The browser should remember it's size for next time you open a window or new browser session

If you can't avoid being maximized, because you choose to not reuse the last window size (in settings) and are always maximized [edit: or because you maximize after opening], then this is going to take some discussion upstream, and an issue opened, for UX people. Likely to be super low priority, but I also don't see it as particularly hard to horizontally align left|center|right, even if only behind a pref initially.

Hi, yes I am maximising my screen, and that's very much my preferred style. I would have thought that was how most people use browsers.

I would have thought that was how most people use browsers.

The only way to know is to get some Mozilla telemetry (which is just anonymized numbers) on window states/positions/sizes. For example, having lots of real estate on my monitors, and multiple windows (apps and browsers) open, I prefer windowed apps - and some users like to tile them: tiling would also result in a LB margin showing (unless they were incredibly lucky)
