Comment 5 for bug 267260

Do the listed browsers do that somehow?
If so it probably makes sense to list them individually (but if listed individually, one should at least all of them). Otherwise it just as reasonable to have $www-borwser and still can install the plugin without getting another $www-browser (while in most cases when someone installs the plugin, he/she probably wants to use it, in some cases this might not apply, like when a meta package pulls it in).
