Mozilla resolved a problem that caused Firefox to freeze when copying text on Windows 11 devices with the Suggested Actions functionality enabled. The problem affects Firefox users running Microsoft’s most recent operating system, Windows 11 version 22H2. This version has the Suggested Actions functionality enabled by default.

According to a customer complaint filed five months ago, the browser stops for more than 20 seconds, during which the entire window fails to respond to inputs. The complaint says that videos and animations seem to keep playing. After a while, the browser regains responsiveness. The duration varies and appears to be influenced by the number of extensions installed. 

Mozilla patched the flaw in Firefox 106.0.3

The release notes of Firefox 106.0.3 mention that incompatibility with the new Windows 11 22H2 Suggested Actions features caused the freezing when copying text on a web page. Users of Windows 11 who are unable to update Firefox at this time are recommended to disable the Suggested Actions functionality to prevent their web browser from freezing.

How to deactivate Suggested Actions

To deactivate the Windows 11 functionality, follow these steps:

  • Press the Windows key on your keyboard or go to the Start menu and search for Clipboard.
  • Press the Enter key or choose Clipboard Settings from the list of options. This will take you to the clipboard settings of your system.
  • Turn Suggested Actions off.

Mozilla Firefox 106.0.3 also resolves a second bug which causes startup failures for users running all Windows versions. A user complaint states there were 260 crashes from 220 Windows installations of Firefox 106.0 and 106.0.1.
