Well, personally I use Firefox. Although I do have a suspition that Google has found some way of keeping Firefox experience on mobile inferior in some way. Just speculating.
Would Google also be able to negatively influence such an app if the app was a PWA? Publishing PWA on Play Store might still lead to the same outcome, but what if it is just an independent PWA and is "installed" through the phone's browser? Of course you would loose some discoverability though, but are there other disadvantages? (provided the app is even feasible as a PWA)
the banks have too much cash and not enough collateral (typically bonds). The FED lends them the bonds for one day (reverse repo) so that their books look ok at the end of the day.
There is also browser.compactmode.show set to true that will allow compact density. Unfortunately that won't reduce the padding around bookmark entries. For that can go to https://github.com/black7375/Firefox-UI-Fix/
Setting browser.compactmode.show to true in about:config allows for setting density to compact again. But unfortunately the padding around bookmark entries remains huge.
