Best addon that is capable of saving a page as a real (not rasterized) PDF with selectable text, working links and preserving layout as seen on screen. Removing one star because "Web style" is not working 100%. Some print vs screen media css is still messed in the generated PDF breaking some pages. I'll give full 5 starts when fixed.

The addon needs quite a lot of tinkering with "scale" option to have the page saved looking exactly as in the browser. Consider implementing some automatic formula for the scale option based on the window size and the page width so the exported PDF will look the same as on the screen.

Also consider adding an option to export the web into a single page HTML with automatically calculated PDF page height. It can be hacked manually tinkering with the page height but it requires a lot of manual trials and it could be automated. Then one could do something like a "pdf screenshot".
