Firefox tab bar goes grey and Firefox is unresponsive on MacBook Air after closing cover
For the past few months, when I close my MacBook Air, for no particular amount of time, can be short or long, upon reopening and unlocking, I frequently find the Firefox tab bar has gone grey and Firefox is unresponsive. I quit Firefox and start it again immediately and it returns to normal operation and runs fine until I close my MacBook again. Firefox 145.0 (aarch64) with MacOS 15.6.1 (24G90) running on a MacBook Air M1 2020. Currently 33 tabs open across 3 windows. Performance is usually acceptable. Sometimes Gmail slows down, but I reload the tab, then it's OK.
