1806457 - Google Drive has a warning about missing copy/paste features in Firefox

Status: VERIFIED FIXED

(Web Compatibility :: Site Reports, enhancement)

Description

[Tom S. (please needinfo tschuster)]

Attachment: warning.png

Steps to reproduce:

• Go to drive.google.com
• Select multiple files
• Press Ctrl + C (Copy)

It seems like setting dom.events.asyncClipboard.clipboardItem to true makes the warning on copy go away, but pasting doesn't seem to work.

Edgar, is this something that's on your radar?

Comment 2

[Edgar Chen [:edgar]]

Yes, I have aware this, but not sure if there is anything we can do, since coping/pasting file in Google Drive doesn't work on Safari that already supports async clipboard API, either. Maybe there are some other reasons that makes the feature only working on Chrome.

Is this just about the warning or does pasting also work for you? Even with latest Nightly, When I press control+c, move to a different folder and press control+v, the file is not pasted.

Hello..Just about the warning. You're right, I've retested and the pasting doesn't work.

We got a response from our partner. It looks like web custom format is needed. I filed bug 1956304.

I selected some file in Google Drive and press ctrl+c, then use https://edgarchen.github.io/dragndropclipboard/ to check the clipboard data that is exposed by paste event or async clipboard API. I didn't see the custom type being used/exposed.

But I do see Chrome put some special data into OS clipboard, please see the attachment. AFAIK, that data isn’t in the same format or doesn’t use the same names as custom types, it looks like something different. I’m not sure how Chrome writes them into OS clipboard, or whether that data is the reason keyboard copy/paste shortcuts don’t work in Google Drive on other browsers.

Edgar - Are you saying this isn't an issue with Web Custom Format (bug 1956304)? If so, what's the next step to diagnose this?
If it is that bug, then that has a size estimate of L; I don't know if it's been scheduled

No, it isn't a issue with web custom format.
There was an update from Google last week - "Google Drive files copy/paste support for FF is rolling out now and should be complete by ~next week".
And I just tested it, Copying/pasting files within Google Drive works for me now.
Could you help to also test on your side?

[Hsin-Yi Tsai (she/her) [:hsinyi]]

I can also confirm that copying/pasting files within google drive works for me.
I also modified certain fields to reflect the current situation, also based on the outreach response we got from Google.
