Great to see another map with satellite images, besides Google Maps and Microsofts Bing Maps.
Now they just have to stop blocking Linux based on the user agent. If I set it to Firefox on Windows, it works, but not if set UA to Linux. A major feature of browsers is that web devs don't have to care about the underlying OS...
I've been contributing a lot to OSM for my local area, and have added a couple dozen businesses, and updated a dozen more. It's pretty easy, and I've really been liking OrganicMaps on mobile for directions and whatnot.
For others: if OSM kinda sucks in your area, you're not SOL, you can add whatever it is you're missing. It's easy and IMO pretty fun. Give it a try!
You can. It just show you everything that need additional info. You can just choose to move the map to the shop you want to edit hours and do that. You can also filter the StreetComplete missions in the settings if you want to only update business hours and description.
I've just found out about the about:compat page in Firefox. It looks there's a few dozen pages with user agent overrides in latest Firefox, some seem to be overridden to chrome. If you open a ticket on bugzilla, they might add an override to fix your environment too.
