opening rather than saving pdf files

more options

I cannot open PDF files without saving them to my computer. At the moment I use foxit reader and I'm wondering if this is the problem. I've tried everythng that is suggested on the Mozilla help pages but there is never an option to choose 'open this file' - it always forces me to save it. I also installed adobe reader to see if this would help but no joy.

That may be the problem, but to test that try to reinstall Foxit, then delete the mimetypes file in the profile (after reinstall).

Foxit Reader has a Firefox plugin, but I don't see it on your More System Details. If it wasn't included, maybe you need to download it from the following page:

http://www.foxitsoftware.com/Secure_PDF_Reader/addons.php

Or following this suggestion:

To manually install a critical or an advanced add-on, please run Foxit Reader, and then go to "Help" > "Install Updates" > browse and choose the related downloaded package, and then click the "Open" button. When you're done, click "Done" to finish the installation.

Does that work? You can check on whether Firefox found the plugin (sometimes exiting and restart Firefox is needed) by checking the Add-ons page:

orange Firefox button (or Tools menu) > Add-ons > Plugins category

If it doesn't appear there, check out the following article as a possible additional settings change:

Any luck?
