Get ready for a new look for Firefox's icon -- again.

Less than a year after launching a simplified, brighter icon for its Quantum-branded versions of Firefox, Mozilla has begun another effort to modernize the icon. This time the plan isn't just to create a new Firefox icon but to craft a family of icons to accommodate what the nonprofit does beyond its flagship browser, such as new services or Firefox variations like Rocket and Focus.

"As an icon, that fast fox with a flaming tail doesn't offer enough design tools to represent this entire product family," said Madhava Enros, senior director of Firefox user experience, and Tim Murray, Mozilla's creative director, in a blog post Monday. "Recoloring that logo or dissecting the fox could only take us so far. We needed to start from a new place."

As a starting point for discussions, Mozilla offered two high-level "master brand" icons that can be rejiggered into a variety of incarnations for its services and software. One master brand is a stylized fox head, the other is a circularly curving flame, and both are examples of what's possible rather than final ideas.

Changing brands is a risky business. People can be annoyed when they can't find what they're looking for, and sometimes new designs trigger mockery and derision.

But revamping icons and logos also gives a chance to modernize for a fresh look. Firefox's icon over the last decade has moved away from its original 3D look of a fox wrapped around Earth to embrace the prevailing "flat" design style.

Plus, linking multiple icons with a unified design style can be useful. Many of Google's services employ the company's characteristic red, green, blue and yellow color pallet, making new apps more recognizable. And when Facebook's Instagram changed its icon in 2016, the company picked a style that could apply to its subbrands, too, like Layout, Boomerang and Hyperlapse.
