Details
User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:95.0) Gecko/20100101 Firefox/95.0
Steps to reproduce:
Single clicking in both Firefox and Thunderbird (XUL based applications?)
Actual results:
Random double click instead of a single click
Expected results:
A single click. I tested my mouse in other applications, it never randomly double clicked there.
Usually I'd blame my mouse (hardware or software error), but no matter how much I tried, I only have this issue in Firefox and Thunderbird. My mouse never randomly double clicks in any other application I tried. This must be a bug with the framework.
Using WIndows 11 by the way.
Just to add: I tried out a different mouse (Unplugged the old one, disabled driver, other mouse is from another manufacturer), exact same behavior, one random double click every 5 to 10 clicks.
I've managed to get this bug in Firefox, Thunderbird and strangely Edge by now. Applications where I can't reproduce it even once are Visual Studio 2019, Notepad++, Windows Explorer, Windows Notepad, ...

The Bugbug bot thinks this bug should belong to the 'Core::DOM: UI Events & Focus Handling' component, and is moving the bug to that component. Please revert this change in case you think the bot is wrong.
Nevermind, I fixed it:
Uninstalling the mouse drivers and replugging the mouse didn't help. But uninstalling the drivers and rebooting Windows 11 seems to have fixed it. The weird thing was that it just influenced browsers and Thunderbird, but not any other applications and games I have running.

On Windows, some mouse drivers/utilities check the process name or window class name under the cursor when they try to do something. Therefore, application specific issue could happen even if the application does not have any problems. I experienced a lot of odd bug reports caused by touchpad drivers about 10 years ago and earlier. I'm not sure the state in these days though.
