The default copying functionality in Firefox is somewhat limited, which requires users to change a setting to enable a copy experience similar to that of Chrome, where you can easily paste images into various websites or platforms.
Follow these steps to enable enhanced copy functionality:
about:config into the Firefox address bar and press Enter.
2. Click 'Accept the Risk and Continue' when prompted with a warning message.
3. In the search box that appears, copy
dom.events.asyncClipboard.clipboardItem and paste it there.
4. Toggle the setting from 'false' to 'true' by clicking on the switch button.
You should now be able to use the Copy function with greater flexibility. You can close the
about:config page after making this change.
