As a spin-off from another thread, I thought it would be useful to mention useful addons for Firefox.
(I am excluding the Security addons that everyone knows such as NoScript, Adblock etc)The first is called Print Edit.
It installs in firefox and gives you the ability to print from webpages and edit out the bits you don't want.
If you have a page with a section containing some information you want to keep, you can print the page and before it is sent to the printer you can select and delete sections from the page.
You use the mouse to click/select things to delete.
It even has a clever select things and delete every else ability.
Really useful to save paper when printing pages full of ads and/or useless graphics.
Even better if you install something which gives you the ability to create .pdf files from a virtual printer. i.e. Foxit Phantom PDF
You can then print the edited page directly to a .pdf.
(Foxit Phantom PDF is a PDF reader, Editor etc. The printer functionality is a small but useful part of its features.)
