Firefox will allow you to write and draw in your PDFs
There's a new feature coming soon to Firefox that doesn't look like much but will save you time as well as make you happy.

Reported by Maxime, a regular reader of Korben.info, this new feature is only present in the Dev version of Firefox for the moment and I had totally missed it. It's about the PDF viewer integrated in Firefox that allows -at last- to annotate with text or small drawings any PDF.

Really handy for making changes to a PDF or simply making simple changes. Just take the drawing tool and cover the text with white, before writing over it again with the text tool. It's not a real PDF text editing tool for the moment because you can't edit the existing text but it's not so bad, I think.

Can't wait to have this in Firefox Stable.
