Why did the latest upgrade of Firefox change the toolbar icon on MacBook Pro but not on iMac?
The latest upgrade to Firefox on my MacBook changed the icon in the toolbar to something that looks like a sheet of paper with an A made from a ruler and a pencil? Remained the same as always on my iMac. Prefer the old icon
Additional System Details
- Shockwave Flash 32.0 r0
- User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.14; rv:64.0) Gecko/20100101 Firefox/64.0
What you're seeing is the icon macOS uses for apps that don't provide their own icon, which likely means that Firefox's icon file got corrupted somehow during the upgrade process. Sometimes, this will fix itself the next time you launch the app, but if that doesn't work, can you try going to https://www.mozilla.org/ and re-installing Firefox?
