Thanks for the report.

I was indeed able to reproduce the issue. After I click on a link and access the corresponding page, clicking the browser's back button on Firefox redirects to the top of the previous page while on Chrome I am redirected to the previous page having the link in focus.

Tested with:
Browser / Version: Firefox Nightly 72.0a1 (2019-11-25), Chrome 78.0.3904.108
Operating System: Windows 10 Pro

Moving to needsdiagnosis.

This looks like the wikipedia viewer issue :) #45023
https://bugzilla.mozilla.org/show_bug.cgi?id=1563587

https://www.fxsitecompat.dev/en-CA/docs/2019/history-navigation-methods-are-now-asynchronous/

Starting with Firefox 70, the history.back, history.forward and history.go methods will behave asynchronously like Google Chrome and Apple Safari. This change may break any site relying on (browser detection and) the synchronous behaviour which can still be seen in Microsoft Edge, as pointed out in a bug comment. You can listen to the popstate event to know when a history navigation is complete.

but fwiw on macOS and the latest Firefox Nightly this is working for me. So I'm not sure.

1. go to https://www.derbund.ch/
2. Scroll a bit
3. click on a link
4. wait for the page to be fully loaded
5. hit back button
6. The page comes back at the same position than initially.

It seems to use

window.Twenty.appVersion
"1.0.3195"

and this framework seems to control history.
