Copy Plain Text is an extension for the Mozilla Firefox web browser, really small in size, used to copy a completely flat piece of text. That is, leaving aside the format that it may have: neither bold, nor italic, paragraphs, etc. This extension allows us to copy only and exclusively the text as is.
Copy Plain Text can be configured as the default copy option of Mozilla, to avoid having to use different methods to copy text. You can also determine the option of not copying spaces or line breaks.
You can free download Copy Plain Text 32, 64 bit and safe install the latest trial or new full version for Windows 10 from the official site.
