Mouse unresponsive to elements in the browser and on webpages
In Firefox, the mouse becomes partially unresponsive to elements in the browser and on web pages. This happens after 15-30 minutes after starting up the browser. Common symptoms include:
- Unable to drag and drop elements properly, including text after highlighting it. - Sometimes, the mouse continues to hold elements while dragging. Pressing ESC temporarily fixes this. - Dropdown menus on websites do not drop down when hoovering over them - Other items on websites don't display items when hoovering over them
I have tried:
- Different mouses, including my laptop's trackpad - A Firefox fork, namely Waterfox, but it still occurs - Limited testing with other browsers. No problem occurs - Limited testing on desktop. No problem occurs - Entering Troubleshooting Mode on Firefox - Clearing cookies and cache - Reinstall Firefox (including installing from command line instead of the snap store) - Updated Firefox - Refreshed Firefox - About:Processes doesn't show anything using more than 10-15% of CPU at any one time - Limited testing with a new Firefox profile. No problem occurs - Disabled WebGL and Hardware Acceleration.
Temporary fix: Restarting Firefox, but the problem re-occurs shortly after use.
Using Ubuntu.
Any help would be greatly appreciated.

Start Ubuntu in Wayland and set the environment variable MOZ_ENABLE_WAYLAND=1.
Try a different package, if you are using the default snap package, try flatpak or a manual install.
Does this still happen with a new profile after using it for a longer time since you wrote: Limited testing with a new Firefox profile. No problem occurs

No luck with Wayland and have already tried a different package.

I did about a 15-20 minutes of testing, and the issue didn't occur. It happens completely random, so sometimes the bug doesn't occur for hours. Other times, it repeatedly happens every 15-30 minutes.
Go to about:config in the address bar and create ui.primaryPointerCapabilities (Number) with value 6 to indicate you are using a mouse with hover capability.

Have tweaked this setting - will update you in a day or two!

Hi - unfortunately the issue still persists after changing this setting and testing for a couple of days. Any additional help would be greatly appreciated.
What is the "Window Protocol" value listed in about:support? What version of Ubuntu?

Window Protocol isn't set to anything. I.e it asks for Boolean, Number or String.
Ubuntu 22.04.3 LTS
It sounds like you are looking in about:config instead of about:support. Another way to access it is in Menu > Help > More Troubleshooting Information.

Sorry, misread! Window Protocol is xwayland.
When you apply MOZ_ENABLE_WAYLAND=1, the Window Protocol should change to "wayland" (without the x).

How do I change that variable?
It's an environment variable, so you can export it or use it on the command line:
MOZ_ENABLE_WAYLAND=1 firefox

I get this on the command line: Not loading module "atk-bridge": The functionality is provided by GTK natively. Please try to not load it.
It then opens a fresh Firefox window and Window Protocol remains as xwayland.
Any additional help getting this sorted would be greatly appreciated
