1789672 - Copy Paste of text freezes all web frame instances in single Firefox application window for approx. 30 seconds or longer unless about:config --> accessibility.force_disabled=1

Status: RESOLVED DUPLICATE of bug 1774285

(Core :: Disability Access APIs, defect)

Description

[Kevin Coleman]

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:104.0) Gecko/20100101 Firefox/104.0

Steps to reproduce:

Make sure accessibility.force_disabled value is set to 0.

Restart Firefox.

Press ctrl+c on any selected text in any website (reddit.com, lansweeper self-hosted instance, misterfpga.org, etc...).

Actual results:

There will be a 30 second to 1 minute delay before I can interact with anything on any websites in any of the tabs, the whole frame is frozen. The application itself is not frozen however.

Expected results:

Copy paste should not freeze the rendered web page frame, it should just copy paste immediately to the user.

This is due to a bug in Windows 11 Insider beta. This has apparently been fixed in Insider dev, but Microsoft are unfortunately taking forever to roll it into beta. See bug 1774285 comment 35 for a workaround.
