Hello there. There is one issue that can be really annoying sometimes. When you copy some image to clipboard (e.g. with Snipping Tool on Windows) it cant be pasted on sites that have this possibility. It worked on me only on Pasteboard fro m time to time (it also fails there but not in 100% cases). I'm using the latest build on Windows 10. Would be very nice if you look into it.

Can you provide the url of a site to which you wish to paste a sniped image? Most of the time, websites require that you save the image somewhere and insert a link to the image.

Hanlon’s razor is an eponymous adage named after Robert J. Hanlon that states: “Never attribute to malice that which is adequately explained by stupidity.”

Actually almost every site that supports a feature just to paste a picture from clipboard, for example in a message, and site uploads it right away.

For example, and most important - https://vk.com

In every other browser I can just copy an image (not url) from anywhere, even from paint in windows or just right after PrintScreen was pressed, and just press ctrl+v when chatting, image will upload and attach to a message. But not in K-Meleon for some reason.

Actually it will work if I will copy an image in Google Chrome and then paste it in K-Meleon, it will work. But not if I will copy it in K-Meleon.

Other examples where it does not work:
https://discordapp.com/
https://www.facebook.com

Interesting that it does work perfectly in telegram - https://web.telegram.org

Does it help if you set in "about:config": "clipboard.autocopy" (without the quotes) from false to true?
"dom.event.clipboardevents.enabled" is already set to true in the default configuration.

Unfortunately, no, it does not help

Also it works in Gmail, when making a new message.
And does not work in Hangouts, but it has this possibility too.

Oh, didn't expect someone else to report this problem here. I experienced issues on every site listed above, but this feature works like a charm in telegram web for me as well.

Known bug - incompatibility with some modern JS-modules from recently updated sites (yes, social nets first)
