the first thing I would be doing, since you stated it is important to use the Viewer and not the Editor, is to remove the editor from the system so it's not an option. You should then find configuring the viewer is as simple as setting the file associations from within the viewer to activate the browser plugins.
I should point out however, as Radi mentioned, the viewer is no longer actively being developed and support for it includes only existing features.
If posting files to this forum - you must archive the files to a ZIP, RAR or 7z file or they will not be uploaded - thank you.
