Cannot interact with play buttons on the website in the Firefox browser

[Kostiskat (kostis)]

I am unable to join games, done either via clicking the “Play” button or the “Join” button when you go to the server tab for each game. I am able to join games like normal in other browsers like Edge or Chrome.

Browser information
Firefox version: 139.0.4 (64-bit)
Extensions installed: uBlock Origin (disabled for roblox.com), Return Youtube Dislikes

Relevant media demonstrating the bug:

System information:
GPU: NVIDIA GeForce RTX 3050
CPU: Intel Core i7-10700K @ 3.80 GHz
Memory: 16.0 GB DDR4 @ 2400MT/s

Expected behavior

I should be able to play/join games with the Firefox browser.

Could you try clearing your local storage?

If that doesn’t work could you right click → Inspect → and see if there are any errors in the Console tab?

That (clearing local storage) seems to have fixed it. Do you know why this bug is caused? Is it on Firefox’s side or just some unidentified strange behavior?

Currently I don’t know the exact details, but it is on our list to investigate / fix.
Sorry for the inconvenience!
