Browser widget and PDFs

Thank you all for your responses, they helped me solve the problem for my part. It is indeed the Adobe web Plugin that is the key to this. Although I have never checked that I would like to use this plugin, it seems as if just launching Acrobat will do this automatically. In the Acrobat preferences the check button for this  is set to true, and the button is disabled. I ended up removing Acrobat from the system, but I could probably have followed Hermans advice and just remove the plugin from the Internet plains folder.

Now I have to ask my student to do the same in order to have the pdf-files displayed without all the bells and whistles provided by the plugin.

Best regards

Here, the browser widget displays pdf-files without any hiccups. On my MacBook I have Adobe Acrobat installed, and the browser widget seems to use Adobe Acrobat to display pdf-files inside the widget. When I remove Adobe Acrobat from the application folder, trying to view a pdf-file in the browser widget will prompt me to locate either Adobe Acrobat or Adobe Reader. Are there any way I can «force» the widget to ignore Acrobat or Reader entirely, and will I be able to view pdf-files in the widget on bothMac and Windows if I do so?
