Scroll position is reset to the top of previous page when navigating back after a specific scenario

alinamoldovan84 commented 9 months ago

Steps to reproduce

This issue reproduces intermittently. Using the steps below I was able to reproduce it constantly, but the reproduction steps are not limited to those written by me below.

Open wiki page and search for Italy
Scroll down to ‘Kingdom of Italy’ link and tap on it
Scroll down to ‘League of Nations’ link and tap on it
Scroll down to external links and expend the section
Tap on “history of league of nation” link
Scroll down to the end of the page
Tap Back arrow and check the views

Please note that:

the using the above steps the issue is not reproducing if user swipes-left or the step 6 is skipped.
Able to reproduce intermittently using the iPad Pro 4th gen (16.6) by navigation thought the wiki pages (not needed to go to the external links)

Expected behavior

The scroll position should be restored half way down the page where the tapped link was.

Actual behavior

The scroll position is not restored for the “Kingdom of Italy“ and “Italy“ pages

This issue is still reproducible on v9000(40522), with iPhone 14 Pro Max (16.2).

Hi, I see this yes marked as S3, but it's been an open issue for about six months. I don't know what other priorities Firefox has right now, but this is easily the most annoying bug I experience in the browser. It's gotten to where I open every link in a new tab instead of simply clicking links.

It'd be great if this could be fixed.

Note: underlying culprit might possibly be related to https://mozilla-hub.atlassian.net/browse/FXIOS-9160 ( https://mozilla-hub.atlassian.net/browse/FXIOS-9160|smart-link ), though these are slightly different bugs.
