Firefox Continuously Freezes/Crashes When LG Monitor is Plugged Into Macbook Pro

Ever since the last Firefox update, the browser continuously freezes/crashes when my laptop is connected to my monitor via the HDMI port.  This occurs after my laptop was put to sleep & then re-opened, not when the LG monitor is initially plugged in.

Please fix this bug/conflict with Apple's OS 15.1.1, Firefox.  Thanks.

It can't load basic internet browsing on a high powered computer.... completely useless browser. The company will sink if they don't get their act together. It's been one disaster after another for the past two years.
