PDF articles are now slightly fuzzy when viewd and printed, they were much clearer a couple weeks ago prior to the most recent update, I think?


PDF articles used to be very clear and now the print and images are fuzzy. When I download them and open in acrobat they are clear as they used to be. What has changed? I tried to change the options to open the pdfs in acrobat but that did not help. How can i fix this? thanks

hello, firefox 19 has introduced its own integrated pdf viewer - if you want to switch back to the plugin you've used before to view pdfs just go to firefox options > applications & scroll down and define the default action for the portable document format (pdf).

View PDF files in Firefox without downloading them

Hello Prior to posting the question I went to tools-options and changed the action to view adobe acrobat forms in adobe acrobat (default) from adobe in firefox and it did not change anything. Any other suggestions? Thanks

it's the portable document format (pdf) entry that you will have to change!

Sorry and thanks for your patience. I did not realize there was also a pdf entry. I should have read your response more closely. Thank you very much it is back to as it should be.
