Forced to scroll up after going back to previous page
S/W: Firefox 77.0.1 (64-bit) on Windows 10
After I go back to the previous page, Firefox forces me to scroll up.
My post on Twitter illustrates the following behaviour:
- Open a new browser tab with Pocket articles
- Scroll to bottom of page, then scroll back to top of page
- With address bar, navigate to https://torontosun.com/
- Scroll down the page
- Go back to the prior page
- You must now scroll up the page past all the Pocket articles
Thank you for your assistance.
Regards, Peter

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.
Ugh, why Firefox, why?
Somehow when you go back, the memory of the vertical scroll position in the new tab page is getting overwritten by the position on the site you visited next.
There was a problem in Firefox 76 where, when you opened a local page from disk, such as a bookmark export file, using the file:// protocol, and then scroll down and used a link to navigate to a different page that used the http:// or https:// protocol, when you went back, the scroll position was lost and the page reloaded at the top. The change that caused this was rolled back for Firefox 77.
The new tab page is an about: page, not a file:// protocol page, but the rollback may have left something in place that causes this. To tease out exactly what happened, it would be helpful for someone to:
(A) Search for any recently filed scroll position bugs on https://bugzilla.mozilla.org/ , and if one is found, probably no further action is needed unless they need another test case
(B) If there's no bug, run a mozregression to see which change caused it and file a new bug pointing the finger at that change

Thank you for your suggestion. I do that, too, on sites I know behave badly, e.g. procom.ca. In the example demonstrated, there is no link to checkout. Forward navigation is executed from the address bar.

Thank you for your insights. There were similar reports raised circa Firefox 65/66 surrounding the "scroll anchoring" bug. I toggled layout.css.scroll-anchoring.enabled, but that didn't change the behaviour I noted.
