I use Firefox, Firefox Nightly and Thunderbird on Windows 10 and 11.The current Firefox Nightly icon looks very similar to the Thunderbird icon, making it difficult to distinguish between them on the Windows taskbar.I suggest introducing a distinctive orange-colored icon specifically for Firefox Nightly, different from both the standard Firefox icon and the Thunderbird icon.This would make all three applications easy to recognize at a glance.Ideally, users should also have the option to choose their preferred icon.
Thank you for considering this suggestion.
