When opening Firefox, the window shows a white screen indefinitely, and the cursor shows loading whenever it is held above it. During this period, the desktop and taskbar of my computer freeze completely. There are no reactions to hovering my mouse over taskbar icons, clicking anywhere results in a loading cursor, and other windows are no longer usable either. This carries over through multiple desktops and monitor extensions. This is resolved with a couple presses of the Windows key on my keyboard, which after a couple of seconds, turns the entire screen black apart from the Firefox window and reloads the desktop and taskbar. Doing this makes them usable again, but when attempting to close, click and drag, or manage tabs on the window, all tabs on the window freeze, as well as the desktop and taskbar once again. This can be resolved with the Windows key just as before, but it is disruptive to general computer workflow. What's more, certain other application windows open on the screen, including the file explorer, will close between refreshes, making work with multiple windows more difficult. I am running Firefox 128.0.3 (64 bit) on a Windows 11 computer. This issue began yesterday (August 2, 2024), but it supposedly fixed itself that afternoon and came back this morning. I run Firefox with automatic updates, so I am unsure if this correlates with a software update. Removing the add-ons I used did not resolve the issue, and I use three extensions that were downloaded months ago with zero detrimental effects. I have data for bookmarks and favorites transferred from my Google Chrome browser, which I've dropped in favor of Firefox roughly 6 months ago with no issues. I have already tried Mozilla's recommended troubleshooting methods in order to resolve this issue permanently. I have restarted my computer multiple times. I cleared my browser history, cookies, and data, uninstalled and re-installed Firefox, and refreshed Firefox from the troubleshooting information page. All to no effect.
