Always used Firefox and always will while it lasts. But this year I found out that Google Maps is getting really broken to the point where I have to run chromium just to use it. Anyone having the same issue / knows how to fix this ? Pretty sure its just a case of Google wanting me to migrate but that won't happen. (While OSM and alternatives are probably quite good I'd like to keep using GMaps though)
