Over the years users have reported some sites that add back button history as you scroll down the page, and possibly as you scroll back up the page. I don't know why that happens, whether it's an incompatibility with Firefox or with an add-on. Do you notice a pattern of particular sites that cause this issue?

I get around this by; When I find a link I want to check out, I open it in a new tab/window. Then when I am done, I close it and am back where I started.

Same problem - back button fills up with dozens of references to the same page. Can't click 'back' to navigate. Very frustrating

If you right-click the Back button, are there so many references that you cannot skip over them back to the previous page?

Do you notice a pattern of particular sites that cause this issue? And/or can you provide a link to a page that does this?

for a demo, visit THEHILL.COM, load comments for an article. See attached image

I'm not seeing this.

Start Firefox in Safe Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration is causing the problem.

• switch to the DEFAULT theme: "3-bar" menu button or Tools -> Add-ons -> Appearance
• do NOT click the "Refresh Firefox" button on the Safe Mode start window

What if you disable Tracking Protection (shield icon at the left end of the address bar)? See also: What happened to Tracking Protection?.
