Duplicate feedback whilst reading edit fields in Firefox

[nvaccessAuto]

Reported by elliott94 on 2015-05-28 18:55
From memory I believe that this particular issue may have been reported several years ago, but I've been unable to find any relevant information.

Whilst using Firefox 38.0.1 in combination with the latest NVDA snapshot (Next 12021,7c7aad1), I've noticed that whilst editing form content in Focus Mode duplicate information is presented. There doesn't seem to be a set of conditions where this behaviour can be observed; whilst moving the focus to the next/previous line or character the previous information for the relevant line or character is given. I've noticed this on multiple machines running Windows 7 Home Premium X64.

I assume you still have video acceleration disabled given #5033? Poor performance would definitely cause this issue. If it were just related to being at the end of a line, that could be #3156.

I do still have this setting disabled - general performance returned to normal after disabling this particular setting.

If it were just related to being at the end of a line, that could be #3156.

I think the behaviour outlined in #3156 mirrors the experience that I'm having. I'll close this as a duplicate for now, but will reopen this ticket if I have any more information.

I'm reopening this ticket after observing further behaviour - outlined below.

Whilst at first it appeared that this only occurred whilst using the cursor keys to navigate text within a form entry field, I've now noticed this whilst in the Search field (Ctrl+K) of Firefox. Furthermore, this behaviour can be seen when not focused at the end of a line, i.e. when simply cursoring down through an edit field. It's important to note that this only happens within edit fields - either in a multiline (such as can be found within Trac), or as previously mentioned in Firefox's Search entry box.

Changed title from "Duplicate feedback whilst editing form content in Focus Mode in Firefox" to "Duplicate feedback whilst reading edit fields in Firefox"

There are two distinct issues here and I want to make sure we keep them separated. I'll provide a way to detect each case.

1. Duplicate/incorrect reading when the cursor is at the end of a line. That's firefox edit fields: duplicate llines and words #3156. Note that you can end up at the end of a line without intentionally doing this; e.g. if you move to a line which is shorter than the line you were previously on. When this occurs, pressing NVDA+upArrow to read the current line (laptop: NVDA+l) will still report the incorrect line.
2. Duplicate reading when not at the end of a line. This probably occurs because the cursor took a while to move and NVDA timed out, believing the cursor wasn't going to move. When this occurs, pressing NVDA+upArrow/nvda+l will read the correct line, even though upArrow/downArrow reported incorrectly.

You appear to be reporting the second issue, but it'd be great if you could verify the behaviour I explained.

If that is indeed the case, the question is whether you see this with NVDA 2015.3, NVDA master or only with NVDA next. If only in NVDA next, it could be due to #1668, but we'll need to troubleshoot further to isolate that.

Thanks.

You're right - this is in relation to the second case. That said, this behaviour was definitely occurring before any code on this was merged a couple of weeks ago; I've been experiencing the same issue before opening this ticket earlier in the year, but hadn't thought to open it sooner.

If that is indeed the case, the question is whether you see this with NVDA 2015.3, NVDA master or only with NVDA next. If only in NVDA next, it could be due to #1668, but we'll need to troubleshoot further to isolate that.

Thanks.

I'm currently testing with the latest Next snapshot; I can test with other branches if that would help, but since I've been experiencing this for a while before the relevant code from #1668 was merged I'm not sure if that could be the issue.

@elliott94: Could you provide a status update for this issue?

[elliott94]

I'm afraid so - behaviour is still as described. Am I correct in thinking that this is more of a Firefox bug, though?

@elliott94 I am testing several website in Firefox 66.0.2 where such issues occured before and now I cannot reproduce it anymore. I am testing with NVDA 2019.1. Are you still seeing this issue? Thanks!

[elliott94]

Happy to close for now; I haven't seen this for a while.

[Adriani90]

Thanks for confirming. Just comment on it if you have this issue again and we can reopen it.
