Can you provide an exemplary URL with this issue?

It happens with every fill in page. Giving you an URL will probably not help diagnose, since it works with other browsers and it's obviously not a problem with the websites. I tried to post a URL for Amazon Smile but I got a message that links are not allowed in forums.

There is a box for entering my email address does not show up on my page, but it is obviously there. It is also auto-filled, but that doesn't show.

If I click on next or continue, it does log me in. The problem is if I go to a page that I haven't used before, I can't see what info I need to enter, or where to enter it.

Does it happen also in Safe Mode?

I had to wait until I got home from work to try Safe Mode. When in Safe Mode, I have no internet access and saw no way to turn it on, so I don't know if it would work.

It's obviously not a Firefox problem, as I don't have this issue on my work computer. There must be some setting that's not right on my personal computer. I had this issue before after an update and my son fixed it, but I don't remember what he did.

Thanks for trying to help!

I just realized you meant to try Firefox in Safe Mode. I will give that a shot.

The problem is not happening in Safe Mode.

Thanks for steering me in the direction of Safe Mode! I turned off the hardware accelerator (the setting might have gotten changed during an update) and now it appears things are working as they should. Thank you for your help!
