Details

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:141.0) Gecko/20100101 Firefox/141.0

Steps to reproduce:

Earlier this week Firefox indicated that it had installed the latest update.

Actual results:

After the update, I noticed that a single Left mouse click was not doing anything. Often it would take two or three clicks to change screens or follow links.

Expected results:

When I click a link I expect to be taken to the link on the first mouse input.

The Bugbug bot thinks this bug should belong to the 'Toolkit::Application Update' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

Which version of Windows is this on? Does this happen with links on all sites or just a specific one?

Do you have some unusual third-party software installed that is intended to affect the mouse or focus management?
