Ugh. But there is something you can do: run Firefox, with a couple of plugins:
- AdBlock Plus, plus the Filterset.G Updater
- NoScript.
The last mentioned gives you control over Javascript, which is how this Phorm stuff works. By default, nothing runs, but you can set it so that scripts always run if they belong to the site you actively went to,and 3rd-party scripts are blocked - which suits GMail etc.
