I'm running Firefox 18.0.2 on some thin clients with Windows 7 Embedded - basically locked down web kiosks for customer use.
The clients are write protected and all updates are disabled, but once things like Flash or Adobe Reader get out of date trying to access content results in a full page warning about it being out of date. Is there a way to either completely disable this check, or allow a global pass for all websites?
I am aware that I can add individual websites by clicking the icon in the location bar and telling it to always load plugins to that particular site, however this is unfortunately not an option.
The sites the clients have access to is controlled at a network level and occasionally new domains are registered and added - for instance if a promotion is on the marketing team will put up a new website with a new domain. If one of these has any flash or PDF content we will need to manually open the page on every single client and add an exception to avoid the warning.. not exactly ideal.
I have had a look in the about:permissions page and the only option there for plugins is 'Allow' or 'Always ask'. I have this set to allow but the above warning is not influenced by this. The about:config page has also come up dry.
If anyone has had any success with this or knows a setting I've missed help would be appreciated.
