> It's the same build of Firefox on your desktop. It was just updated from version 86 to 87 this week

Distros like Mobian on the PinePhone don't ship vanilla Firefox. They ship Firefox along with custom UI modifications originally borrowed from the Firefox-for-Postmarket-OS project that make Firefox at least somewhat usable on the PinePhone's screen dimensions.

Even when the version of Firefox is updated, the accompanying Firefox-for-Postmarket-OS hacks do not see much improvement. The upstream Firefox devs have not put work into making Firefox’s UI fully usable at those dimensions, and so for time being phone users are stuck with the limited functionality that the Firefox-for-Postmarket-OS hacks provide.

This is a pretty pessimistic view. I'm sure the patches will be upstreamed soon. Even Purism works on that according to their "Fund Your App" page: https://puri.sm/fund-your-app/.

The Firefox-for-Postmarket-OS modifications don’t really patch Firefox in a way that can be upstreamed. They are merely UI settings that disable some elements that would take up too much space on the screen, and much of Firefox's UI still won't work regardless. Only significant work on upstream Firefox itself would make a difference, and neither Mozilla nor Purism have the manpower for that.
