Hello all, a Thank you in advance for any help. Is there any way to change what program opens pdfs in Firefox? I looked under preferences under the "Download Actions" window, but PDFs are not listed. Any advice? Secondly, is there any way to hide all extensions on files in the Finder? I have "Show all file extensions" under the Finder pref's unchecked, but obviously that doesn't do the trick. Is there a "Hide all file extensions" button I'm missing? If there is, is there also any way to just apply it to certain folders? Thanks again guys.
