I frequently have multiple windows open in Firefox. When I hover over the Taskbar icon for Firefox, I receive a list of open tabs (one per window). By scrolling down or clicking on the bottom of the list, all open tabs become visible. This feature is no longer available. Now the list displays up to 18 open tabs, with no option to scroll further, meaning I can only access windows 1 through 18. Windows 19 and beyond are completely missing from the list, or at least I can't see them.

I've tried various solutions to restore this feature, but nothing has worked. It seems to be related to a registry setting, though I couldn't locate it. It might also be connected to screen resolution; adjusting it changes the number of items in the list, but I can only reduce it to 18, not increase it.

Other factors could be involved, such as hidden Firefox icons behind other icons that are always highlighted, even when another application has focus. Some entries in the jump list are marked with highlights without any apparent reason, and this behavior has never occurred before the issue began.

I believe the problem started after the most recent Windows update, though I'm not certain. There hasn't been any new software or hardware installed, nor have I changed any system settings. This issue is really frustrating because it prevents me from accessing all my Firefox windows, which I suspect is a Windows-related problem rather than a Firefox one.

No, it's a "user" problem. No one needs, or can keep track of, that many browser tabs simultaneously.

Why not utilize multiple tabs within a single Firefox window rather than having numerous windows? There seems to be no benefit to doing that. You can accommodate many tabs in one window, and the system is designed intelligently to retain only the latest ones in memory. Doing otherwise would be an unnecessary waste of computer resources.
