Details

I use a JavaScript file to create a 'back to top' icon and function when visitors scroll beyond 350px. In the Firefox (84.0.2 64-bit) Console there was, unsurprisingly, a message about this:

"This site appears to use a scroll-linked positioning effect. This may not work well with asynchronous panning; see https://developer.mozilla.org/docs/Mozilla/Performance/ScrollLinkedEffects for further details and to join the discussion on related tools and features!"

However, if you go to that URL - https://developer.mozilla.org/docs/Mozilla/Performance/ScrollLinkedEffects - you get a 404 error. The correct URL is https://developer.mozilla.org/en-US/docs/Mozilla/Performance/Scroll-linked_effects

Thanks for reporting this @Scrabble96!

So, to whoever fixes this, I'd say that this requires one definite immediate action — to add a line to https://github.com/mdn/content/blob/main/files/en-us/_redirects.txt to redirect https://developer.mozilla.org/en-US/docs/Mozilla/Performance/ScrollLinkedEffects to https://developer.mozilla.org/en-US/docs/Mozilla/Performance/Scroll-linked_effects

And a stretch goal would be to figure out how to update the URL in the Firefox source code to the correct one, so that the redirect is no longer needed.

I digged the source code of Firefox. Here you go: https://hg.mozilla.org/mozilla-central/file/tip/dom/locales/en-US/chrome/layout/layout_errors.properties#l12

Last time touched by @staktrace in 2016 to fix https://bugzilla.mozilla.org/show_bug.cgi?id=1245245

@chrisdavidmills I fixed the link in _redirects - #1590. Leaving the URL update in Firefox for someone else :-)

[staktrace]

Thanks @hamishwillee ! If anybody wants to make to change in Firefox I'm happy to guide them. If not I can do it.

@Aayushap1 The change Kartikaya mentioned would be done for Firefox, which is tracked in Mercurial. Please get in touch with @staktrace if you want to contribute there.

[chrisdavidmills]

The redirect means that the link is not broken anymore, so I'm going to close this one.

[jkillian]

The redirect doesn't seem to work anymore - https://developer.mozilla.org/docs/Mozilla/Performance/ScrollLinkedEffects still goes to a 404

We got a report about this in Bugzilla: https://bugzilla.mozilla.org/show_bug.cgi?id=1723761, should we open a new bug for this?

[staktrace]

@chrisdavidmills is there a way to stop this page from getting moved and/or archived? Or a way to get a permalink to the content that will remain valid? If not maybe we should just move that content off MDN.

[hamishwillee]

I have no idea what MDN policy is, but IMO "necrobumping" issues is always a bad idea. In particular, @chrisdavidmills no longer works for MDN, so will not necessarily be able to see this.

@nchevobbe and @staktrace For now lets follow this on the duplicate open issue #1532
