Mouse slows down dramatically whenever starting recently updated Firefox

dawog — Sat, 23 Mar 2024 02:36:07 GMT

My Windows 7 updated today to v115.9.1esr (64-bit) today. Afterwards, my trackball slows down dramatically whenever I start Firefox & it's window has the focus. Started Firefox in Safe Mode & problem remains. Tried a mouse instead of my Kensington trackball & it behaves the same way. Rebooted PC... problem remains. Whenever active window is not Firefox, mouse/trackball work fine. My PC is Dell XPS 8900 running Windows 7 Professional w/Service Pack 1, 64-bit.

This wasn't an issue with Firefox v115.9.0esr (64-bit)

As Roseanne Roseannadanna says... "Never mind." I uninstalled & reinstalled my Kensington trackball software/drivers for the SECOND time, and this time both trackball (& mouse) appear to be working normally. (I really feel like a turd for posting this bug, especially knowing the 99% of the time it's "user error")
