What happened

In Canvas mode, selecting a portion of a canvas and choosing either "Copy Canvas to Clipboard" or "Copy Box to Clipboard" results in the red error box in the bottom right corner. I have gone through the instructions of ensuring "dom.events.asyncClipboard.clipboardItem" is set to "true" (it was set to true by default in a clean install), but Clipboard access is still denied.

What you expected to happen

I expected to copy the contents of the bounding box into the clipboard.

How to reproduce the problem

Start the app, create a new canvas by copying an image to a raster layer. Open the Canvas and right-click on the image to select either "Copy Canvas to Clipboard" or "Copy Box to Clipboard".

Curious, since you use firefox too. Are you able to star items easily since 6.x series? I have another issue opened where maybe 1 out of 10 star presses actually fills the star in and registers. Wondering if there are a host of new firefox issues.

No, starring items works fine for me in Firefox.

@firesign thanks

Your issue still seems like a Firefox setting imo. Did you restart Firefox completely after making any flag changes? I've had where I've had to fully kill it and reopen for a flag to take effect.

May be worth a shot to:

• set false > kill ff app
• set true > kill ff app
• reopen and try again

That's what I would try and if still not working, then Google if the issue of that setting not working exists on Firefox forums. I usually find some workarounds from other users on their forums.

@ladle3000 Yes, I tried doing the three-step process you described. I also found a post in the r/firefox reddit that suggested toggling both dom.events.asyncClipboard.clipboardItem and dom.events.asyncClipboard.readText but neither worked for me--they were both by default set to 'true' I also tried creating a fresh Mozilla account, restarted but had no luck with that either.

What exactly gives you the problem? I'll see if it happens on my install too.

Edit: nvmd I see you explained well above. I'll try it out on 6.0.2

@ladle3000 Did you ever manage to make it work on your gear?
