Really fast and easy to use. I didn't even know extensions could put buttons in the URL bar. It doesn't request any excessive permissions and at a quick glance the github repo looks clean and trustworthy. Can definitely recommend.

Thank you for this extension!

Essential for anyone who uses multiple map sites

I love maps, and i often switch from one provider to another. This add-on allows me to switch effortlessly between my favorites.

awesome idea

Some map services don't enable the OpenSwitchMaps icon; everything else is great!

It's awesome. Very time saving for editing. I would like to propose Waze Map Editor link also

A really great extension, so useful, I'm so glad that it's been ported to Firefox! The only feature I'd like to see added, is the addition of a routing website. While the OSM homepage does offer basic routing, I miss fully featured routing. Graphhopper is my favourite, but any would be great.

Work really well, "mainly for Japanese OpenStreetMap contributors" should be phrased "mainly for OpenStreetMap contributors, some features useful especially for Japanese ones"
