Let me try a guess: when a user receives an Error 304, it's basically an issue of data caching; I'm cross-linking a reference source from another Forum that should help in defining an Error 304
Reference source: error 304?
-- scroll down a bit to the #6 thread post to see what their members define the Error 304 when it appears on their end
So in this case, all that is needed is to definitely clear your cache and cookies -- if you just uninstall/re-install a browser in particular without making sure that the residue data is removed from your system, it'll just carry over -- it's recommended that you have CCleaner and allow the program to clean all the residue ( when one installs CCleaner, and have it running, the default marks checked on it's cleaning lists are good to use for most users )
Also, if needed, On Windows, you can go on Control Panel > Internet Options, General ( Delete... ) -- when you click on the Delete... tab, another window will open for confirmation; press the Delete amd it'll purge your system cookies and cache
On Firefox, clearing your cache and cookies is just pressing the keys CTRL+SHIFT+DEL
then make sure that Cookies and Cache are checked
As an added, have you made sure that your Adobe Flash has been up-to-date, and that you have no add-ons/plug-ins installed in your browser that may be hampering with the adds -- since Firefox allows users to customize what plug-ins/add-ons they want on their browsers, it'll be a good idea to check one-by-one if these may be the issue -- it means, that you have to disable them and see if there's any chance
Access your Add-on page in Firefox by pressing CTRL+SHIFT+A
