1610084 - Page Down and Page Up not immediately usable on about:addons in FF 72

Status: NEW

(Toolkit :: Add-ons Manager, defect, P5)

Description

[MarjaE]

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.14; rv:72.0) Gecko/20100101 Firefox/72.0

Steps to reproduce:

Open about:addons

Hit "Page Down"

Actual results:

Nothing. I have to click on the page before it accepts "Page Down."

Expected results:

Unless it interferes with other important tools (other keyboard navigation tools, screen readers, etc), about:addons should probably open with the appropriate focus for "page down".

Bugbug thinks this bug should belong to this component, but please revert this change in case of error.

Same behavior in the current Nightly 74.0. It feels a bit unintuitive in my opinion. I would expect the list to scroll when either Page-Down or the down arrow key are pushed.

This bug is more general in the firefox 72 browser, than just the addon page.

Load this webpage and try to use "Page Up"/"Page Down":
https://en.wikipedia.org/wiki/2019
-> no response.
Click on the page then press "Page down" -> the view goes directly to the end of the page.

Load a (big) image from your hard disk (or the web) (reduce your window size if the picture is not tall enough), then use "Page Up"/"Page Down": no response.

With Firefox 71 and before, the behavior was very well.

I'm using Linux.

This should be fixed once we remove the XHTML parent document in bug 1525179.

Comment 5

Is the addon page of FF71 using a html document?

Because the Page Up/Page Down is fully usable in the about:addons of FF71.

So, I'm not sure fixing the bug 1525179 solves the break of FF72.

I just opened up my release Firefox which was at 70 and page up/down didn't work without focusing the HTML document. Same behaviour when it updated to 72.

I updated the XHTML document to focus the inner HTML document when it loaded locally and the page up/down keys would then work as expected. I'm pretty sure this is because the focus is on the outer document which doesn't have much content in it anymore.

Unfortunately since the sidebar (Recommended, Extensions, etc) is still in the XHTML document focusing the inner HTML document would probably be unintuitive for screen reader/keyboard navigation.

I tried https://en.wikipedia.org/wiki/2019 in my release 72 and page up/down worked as expected for me.

I'm agree. I retried with a new profile and FF 72 is now working.

But my personnal profile is still breaking with these keys and FF72.
There is a strange thing with it. I will try to investigate it.

For me, Page Down is no longer working at all on about:preferences. I have to use scrolling software instead. Using 72.0.2 with a lot of accessibility fixes, and can't safely test without fixes.

Ok, with my new profile, I'm able to reproduce this problem if I check the option "Always use the cursor keys to navigate within pages" (Preferences -> General -> Browsing), and I can fix my personal profile if I uncheck it.

Is this a bug, or has the behavior of this option changed with FF72?

Do I have to open a new ticket? Or Is this the expected new behavior?

For about:preferences and about:addons, Page Down is working if I click on the view (F5, click, page down: ok, but F5, page down not ok).
With the above option checked, it's working too, but the behavior is a little different (the scroll is not the same).

Correction: about:preferences is a little different than about:addons.
about:addons:
F5, page down: NOK
F5, click, page down: OK

about:preferences:
F5, page down: NOK
F5, click, page down: NOK
F5, tab, page down: OK

This is because the first focus is locked on the search box "Find in Prefences".

Same behavior with FF71 and FF72.
