Firefox 29 no longer prints properly from the built in PDF viewer

I print several EBAY labels a day. Just upgraded to firefox 29 (not realizing really what had changed - now regretting) and the built in PDF viewer no longer prints properly. It shows the label fine on the screen, but when sending to the printer (I tried two different ones) it just prints out two blanks pages. I tried a number of different printer settings and as i mentioned two different printers. Can't get anything to print now except two blank pages. If I switch the application settings in firefox to use an external 3rd party PDF viewer (e.g. Adobe reader 11, PDF Viewer plus, etc) those work fine. However, the default built in PDF viewer clearly broke in this new version. A very disappointing launch for me as this is critical feature for my use. Yes, I have a work around, but the point (and new bug) is still valid.

firefox 29.0.1 has just been released, which contains a fix for this issue - an update is recommended for everyone affected: Update Firefox to the latest version

Re: Firefox 29 no longer prints properly from the built in PDF viewer

hello, do other websites print normally still? the pdf viewer is still somewhat experimental and under very active development - you could try if the same error is occurring in the current development version, which you can download as an addon from http://mozilla.github.io/pdf.js/extensions/firefox/pdf.js.xpi

in case it has the the same printing problems, you could then file a bug report at https://github.com/mozilla/pdf.js/issues (a github account is necessary for it though) - please also provide a sample document where the error is apparent!

Developer version doesn't fix it. Any pdf from the web will do.

does a normal website (not a pdf) in firefox print as expected?

Yes, but of course that doesn't go into that pdf viewer.

Re: Firefox 29 no longer prints properly from the built in PDF viewer

I started having this problem this morning. I can print from a regular webpage but cannot print a PDF that opens in the browser. I am able to save the PDF and print it from my computer's PDF reader, but I open and need to print many PDFs a day and don't want to save them all to my computer's hard drive so that I can print one page.

@aglass5, this is currently a bug in the integrated firefox pdf viewer that is investigated &getting fixed by our developers. in the meantime you could use a third-party pdf plugin like from adobe that you can enable in the firefox options > applications - scroll down and define the default action for the portable document format (pdf).

How to disable the built-in PDF viewer and use another viewer

Re: Firefox 29 no longer prints properly from the built in PDF viewer

Now - this approach doesn't even work anymore. Yesterday, I was able to point to Adobe reader, or PDF Viewer plus etc and Firefox would spawn that viewer, in place of the internal viewer. Today (with the only thing changing being a windows high priority security update forced download) that approach no longer works. No matter what you select, the internal viewer is always used. very strange. And a major pain now. This is a bone head move guys. Back to I.E. or Chrome it appears....

You can change the action for Portable Document Format (PDF) from Preview in Firefox to use another application like the Adobe Reader or set to Always Ask in "Firefox > Options/Preferences > Applications".

You can set the pdfjs.disabled pref to true on the about:config page to disable the build-in PDF viewer.

You can check the value of the plugin.disable_full_page_plugin_for_types pref on the about:config page and remove the application/pdf part if present or reset the pref to the default via the right-click context menu if you want to display PDF documents in Firefox with another application (i.e. not the built-in PDF Viewer).

Re: Firefox 29 no longer prints properly from the built in PDF viewer

Tried all these - none worked. It did finally occur to me what else changed. Phillip had me download the developer version (see above thread) to see if it fixed anything (which it didn't) it must be the cause of why all these workarounds stopped as well. How can I revert to the released version of that XPI? where do I get that? At least then I can go back tot he workarounds.
