This happens on only 1 of my Win 7 machines. It occurs with both a USB kbd and a wireless kbd. Only CTRL held down continuously reduces the window Zoom. No other key needs to be pressed. Thus, can't use CTRL-+ to restore zoom, though I can click in address bar or use Zoom in the hamburger menu. Another thing that happens is when a Print box gets to the point where it displays the printer name, it cycles rapidly through the list of printers, and it is impossible to change back to any other than the last on the list. It's behaving as if some key were chronically on, but it is the same with the two different kbds. Things work fine in Microsoft applications. Just upgraded today to 62.0. Tried re-loading the installer and doing a fresh install, as well as trying the Refresh suggested in Troubleshooting, but neither of these produced any change. It's as if some kind of crazy kbd shortcut was installed without my knowing it, but I can't find anything that seems that it would behave this way. Sorry, but there's no screen shot that can show this thing. It's possible that I hit some kind of 3-key rollover thing that changed this behavior, but I have no idea what this would be, much less how to fix it.

OK; I noticed the weird scroll behavior in other places. Notably not in Microsoft apps, but also in the Start Menu and Windows Explorer. So, I decided to rollback the latest Win 7 update. This appears to have done the trick. Now this appears to work OK. Reinstalled Firefox 62, and this also appears to work OK without the continuous scroll problem. So this appears to be a system issue, just happening to coincide with FF62 upgrade.

For some reason, can't find the Windows Disk Cleanup.

Thanks for the help. It appears that this had to do with the latest Win update, and also appears not to be specific to Firefox.

Hi, no idea about that cause. Will get back to it but you have errors in your Video Card Drivers for adapterDescription: Intel(R) HD Graphics 4000 driverDate: 3-29-2012

They should be uninstalled and then a clean full version put back in. https://www.intel.com/content/www/us/en/support/detect.html It has provided it's own error message also : direct2DEnabledMessage: [u'blockedMismatchedVersion']

Please try this : uninstall Firefox. Then Delete the Mozilla Firefox Folders in C:\Program Files , C:\Program Files(x86) & C:\ProgramData Then restart system. Then run Windows Disk Cleanup. (Note: This should be Pinned and run Weekly, If never done below expect 10's of gig's) Then run it again and click the button that says Cleanup System Files. Note: your Firefox Profile is saved. But you should make a back up before you do :

Reinstall with Current Release Firefox 62.0.0 with a Full Version Installer

Please let us know if this solved your issue or if need further assistance.

This could occur if Firefox thought the mouse wheel was scrolling downwards (toward the user). Holding Ctrl with that wheel will zoom out (shrink everything). The wheel also will scroll any drop-list that is selected. But... I assume you aren't actually scrolling the wheel so this could be an artifact of something else or a hardware incompatibility.

Uninstalled Firefox after backup (already had done Refresh, which puts a backup on the Desktop). Tried to do Windows Disk Cleanup, but couldn't find the program. In the Start Menu, it scrolls to the bottom as soon as I let the mouse button go. Considering suggestion from jscher2000, I have actually tried removing battery from wireless mouse and using USB mouse, thinking that this would stop a persistent "scroll downwards", but still behaves the same way. I'm out of gas on this for now. Will return to it tomorrow. Greg

Hi gpwidin1, thank you for reporting back. That's a strange side effect and I don't think we would have guessed without your investigating it.
