Re: advertising with flash plugin
OK no worries I will just put up with it - as you say it is probably not a widespread problem. I had thought that everyone using mozilla without a flash plugin would have it, but I am viewing the pages from work (also using mozilla, without flash installed) and I do not get the annoying popup - just an icon in the place of the object, saying 'click here to get the plugin'.
As for the flash plugin not working for me, that's because I use linux so my apps (eg mozilla) are actually compiled in 64 bit mode, and I think the free flash plugin was only available in 32 bit, which
can't be used easily by a 64 bit app. For the most part I have no interest in anything on the web using flash so I just uninstalled it when I realised why it was crashing.
