Hi all, Since a few days all pdf documents that I download (which is a fair few as I am an academic reading a lot of papers) get stored as Firefox HTML Documents and are stored with the mozilla icon rather than the simple pdf icon. While this might be useful for some - although i have no idea for whom - for me it's extremely annoying. I already managed to disable the plugin that automatically opens pdfs in firefox rather than in adobe acrobat, but still everything gets stored in this new way which truly serves no purpose. Every time i open a pdf now my mozilla browser automatically opens, only to give a blank page (as i disabled the plugin) and then adobe opens. I absolutely don't see the convenience of this given that i need to download and work in the documents i want to read and not just simply scroll through them online. Any advice on how to delete the "Firefox HTML document" type completely and change all the documents that are stored as such back to normal pdf documents would be greatly appreciated. For reasons unknown all my pdf files on dropbox have magically transformed in this new Firefox filetype. I hope there is simple and convenient way of changing this, else it will be the end of my days as a Mozilla Firefox user, which would be too bad. Simon
