The group Icon is "Chrome poni" by he4rtofcourage. The group banner is "Six browsers in a row" by Vivaldi Technologies, makers of the Vivaldi web browser.

I had to crop "Six browsers in a row" down to five browsers, to make it fit the ratio Fimfiction wanted. Sorry Safari.

Found a better banner, with the browser ponies themselves instead of just browser icons. But the banner's name and artist is unknown. And I had to crop out IE.
