User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:102.0) Gecko/20100101 Firefox/102.0
Steps to reproduce:
When I copy from a website, Firefox freezes for a few minutes.
This happens:
- I tried it in a few different websites, including GitHub.com.
- when I use mouse to select and copy.
- When I use keyboard shortcut to copy.
- copy from a text input, textarea, or a plain non-editable text.
This seems to happen in the "cold" copy. So if I haven't copied for a while, and I copy, it'll happen. When it becomes responsive again and I copy again, it doesn't freeze.
Actual results:
Firefox isn't responsive for a few minutes after I copy.
Expected results:
Firefox should be responsive after I copy.

Looking at the profile you provided, now I'm quite convinced this is the same issue than bug 1774285. Therefore I'm duping to that bug that showed some progress.
TLDR: there's a bug in Windows 11's Suggested Actions features. They seem to have a fix coming in.
Microsoft suggested turning off that feature in Settings > System > Clipboard and seeing if it mitigates the issue.
Thanks for your help!
