The problem occurred when copying text on computers running Windows 11 22H2, where Suggested Actions was enabled. The hang-up usually lasted about 20 seconds, during which the entire browser window was unresponsive to any action on the part of the user, even though the animations continued to play.
In addition, Mozilla also eliminated the second bug, which caused a critical error in the browser on startup.
Experts add that browser version 102 with extended support does not have such problems, they are inherent in announcement 106, which promises to eliminate these problems in version 107.
