Context menu is cumbersome. However, the Tutakstenkürzel F7 does not work. F7 is occupied in Firefox under Windows for Caret Browsing.
Better take "copy plain text we", this uses F8 that works.

So simple, so effective, so helpful.
We all copy paste. And since a lot of info is of a web page, we copy paste between browser and word processor. And then it's a PITA that your word processor decides that that "nice" font is something to keep. So nice actually, why not make it 50 pt? Oh, and that 10 cm line spacing? That is soooooooo brilliant that you too should share that with the rest of the world!
So just select your text, right click, and copy it with this extension. No silly fonts. No indents all over the place. No secret table placeholders. Just text. What you wanted to begin with. Satisfaction guaranteed! (Cheers erosman)

Lange gesucht und macht genau das was es soll - ich verstehe die wenigen schlechten Bewertungen (und dann auch noch ohne Kommentare) nicht. Was sind das wohl für Menschen?

Good stuff. Allows me to copy the text for a link on a web page, without the link itself, and paste just the text in some space for comments, for example.
