Safari forgets my Plugin settings for web sites
How can I get Safari to remember my selection to Allow plugins on a site?
I have Safari set to Block by default, and would like to set www.bbc.co.uk to "Allow Always", but Safari forgets my setting.
Typically I run into the problem on Sundays when I try to listen to a BBC radio program (Cerys Matthew's show on Radio 6). I bring up the page, click Play, and I get a message that I need to install Flash. I go into Preferences->Security, and bbc is back to "Block". So I set bbc to "Allow Always", reload the show's web page, and then I can play the stream.
By next Sunday, bbc will be back to "Block". The same happens with any other site I try to set a default for. Here's my settings right now, corrected to allow listening to the BBC. It's working now, but by next week it'll be back to "Block" for no apparent reason.
