I need some advice on what plug-ins are all about.
Using a simple example - Firefox has an Adobe Reader plug-in and if I click on a pdf file on a site it opens it for me. If I disable the plug-in and then click on a pdf file on a web site it opens it for me!? The same happens in IE10.
I have just installed Sumatra to deal with pdf files and during the installation an option exists for installing a Firefox plug-in. Firefox deals with the pdf files whether or not that plug-in is installed.
What is the point? Or am I missing something?
By the way Sumatra knocks spots off Adobe Reader:-)
I don't have any PDF reader plug-in in firefox and it opens PDFs in the browser page. As for IE 10 I use the reader tile (win 8) to read PDFs. So I assume you downloaded Sumatra so you could read PDFs in IE10? I then assume Sumatra takes over as default reader in any browser.
Maybe the 'plug-in(s)' just make an entry in the browser list so you can choose it or another one? Meaning if plug-in is not installed it doesn't appear in the list and Sumatra (or another) pdf reader is the default in Windows it is opened automatically.
