One reviewer said that this didn't work on mac when in fact it does. You have to click on the vertical lines in the upper left hand corner and the print will have a drop down arrow beside it. It works great! Thanks.
As other reviewers have pointed out, this add-on does not work in Firefox in OS X. To the developer: At least have the grace to state clearly in the description that the add-on is Windows-only and/or does not function on Macs, rather than waste our time installing, testing and deleting the add-on.
Doesn't work with Firefox (41.0.2) on OS X Yosemite (10.10.5). There's no "Print Preview" entry in the "File" menu, despite the add-on pretends having been installed correctly (no error messages during installation, correctly listed on Add-ons configuration page).
Would be better if button would remember the last print option selected. I prefer not to preview before print, so I always want to go straight to my print dialog. Although this feature works when selected from the Drop Down menu, it does not remember that setting. This requires that you select "Print" from the Drop Down menu every time. UGH!!!
It seems a recent change in Firefox caused this issue (where both "Print" and "Print preview" just trigger the latter). I've just uploaded a new version (awaiting review) that fixes this. Thanks for the heads-up.
I removed it, because it offers the same as Firefox default Print Button. Nothing more. I will install it again back if it offers more editing tools, such as fit webpage to 1 single page, remove extra elements from the pages, etc.
I found this after fighting a GoDaddy receipt page that was printing too big for the page from a simplified pop-up window with no menu or toolbars so I couldn't get to the page options to scale it to fit before printing. A useful add-on but this really should just be how Firefox works in the first place!
Thanks! This add-on is really helpful. However it would be even nicer if the context menu entries would be optional - my context menu is already so cluttered :-( form other add-ons which also unasked put their stuff into the context menu) Also is there a hotkey for the preview and if not could you add one (like ctrl+alt+p)?
