This is the Otwórz w przeglądarce icon for Windows 10. Here we go. Optimized for 32x32 px, these are the simplest icons in the line style. Downloadable formats are PNG and SVG, among others. Icons8 icon pack is unique in providing a huge number of icons designed by the same team of four designers who create the new icons every working day in the same style and with the same quality. Same cool as the Bat Face, huh.
This is a picture of a browser window. It's blank for the most part, and on top has a bar with two black circles and a rectangular bar on the right side of that. There is a large curved arrow pointing into the box, pointing upwards.
