A reader has a problem with the Firefox browser:

“I’ve been a follower ever since almost the beginning of WorldStart. I now look forward to your weekly “Cyn’s Tech Tips” in which you provide subscribers with excellent technical PC information, which I find very informative and rewarding. I’m going to take you up on your offer for some specific technical assistance.

I’m using a 2-year old HP ENVY x 360 Convertible laptop with Intel i7-7500U processor, 16.0 GB RAM, storage of 119 GB SSD on C Drive and 918 GB HD on D Drive, 15.6” Touch Screen Display using Intel HD Graphics 620, and the OS is Windows 10 Home 64-bit (all updates processed). Most of the time this laptop is connected via HDMI to a 24” external DELL monitor. Firefox is my primary web browser.

My issue, which has been going on for several months, is that when scrolling using my mouse (the same happens with many mice that I have) I often experience a sort of “lag”, “hesitation”, “stutter”, and/or “temporary freeze (momentary)”. This only happens when viewing any tabs connected through Firefox including Facebook. I don’t seem to notice it as bad in Edge or Chrome and the scrolling hesitation does not occur in MS Excel or MS Outlook.

I’ve tried practically everything but have not come up with an answer to resolve this annoying issue. Cyn, perhaps you can give me some assistance or direction to try and solve this. If you need more information, please advise.”

First, thank you for your kind words and also for your detailed description. It makes it easy to eliminate a lot of issues right off the bat.  I think I may have a fairly simple solution.

Try clicking the 3-line menu tab and choosing Options.

Then  scroll down to browsing and see if smooth scrolling is checked.  If it is, try unchecking. If it’s not, you could try checking or experiment with unchecking autoscrolling

Hopefully, this will help. If not, please let me know.
