Whenever I wake my mac from sleep, Firefox is unresponsive. I believe the app is not dead, just not repainting the window. Sometimes if I 'hide' Firefox window behind some other app window, then bring it back to top, it'll re-paint. For a while I fixed the issue by disabling GPU usage in firefox. But now, even that isn't helping. Then for a while, removing and reconnecting the USB-C connection to my external monitor would fix it, but now that doesn't help. Have to quit firefox completely and relaunch. Then the app is working again. Using Firefox 146.0.1 (64-bit) on Mac (2.4 GHz 8-Core Intel Core i9, AMD Radeon Pro 5500M 4 GB, Intel UHD Graphics 630 1536 MB, 16 GB 2667 MHz DDR4, macOS 15.7.3)
