i looked at the graph and it seems like the speed of firefox is way more stable. At the moment i think the normal speeds are equal. Chrome has sometimes very big spikes in booth directions (the grey dots on the right sides that seem to be out of order) so the fastes from the records is still chrome, on this one specific date

maybe look info waterfox

i recommend waterfox or librewolf which booth are firefox without bloat like pocket. Waterfox seems to have better support

the screenshot button can be triggered with strg + shift + s

use librewolf, it gets rid of all the bloat mozilla placed in firefox

open streetmap and magic earth have the disadvantage that public transit it not supported. For that i use the local public transit apps. That works very well and shows in most cases more alternatives to the current route than google can
