Using Windows Vista, my Firefox webpages 'smear' as I scroll down.

Text and pictures smear and stretch as I scroll down through pages. See attached. It seems to quit doing this if I run with Add Ons disabled, but I am not sure which add on could cause this. Been using Firefox for years on this system and this is a first. Image attached.

For whatever reason, I long ago stopped using IE, as it doesn't work at all.

hello, probably that's an issue with hardware acceleration - as there are no more updates available for your dated graphics hardware, please try to disable hardware acceleration in the firefox menu ≡ > options > advanced > general (that setting will take a restart of the browser to take effect).

hi again, mozilla's developer's are looking into the issue but are looking for more information. if disabling hardware acceleration helped in your case, would you be so kind to run another test for us:

  • first please re-enable hardware-acceleration in the firefox menu ≡ > options > advanced > general again and restart the browser.
  • download and install firefox 48.0.2 again from https://download.mozilla.org/?product=firefox-48.0.2&os=win
  • in firefox 48.0.2 go to the menu ≡ > help ? > troubleshooting information, copy the contents of that page and paste them here into a reply on the forum? this will help us understand the issue...

thanks a lot! (afterwards you can update to 49 and disable hwa again for the moment)

Well, I disabled hardware acceleration as you asked. I will give it a day to see if it works as I usually only use this PC in the mornings.

We'll see.

thanks, if you could do the downgrade procedure to 48 and taking a snapshot of the about:support data there as soon as it is possible this would be of great help!

Okay, when I click your link to perform the 'downgrade' it takes me to a download of Firefox 49.0.1, not the Firefox 48.0.2 you mention. I dunno how to correct that. Attached is a screenshot.

I think I've got it:
