 firstRun_acceptableAdsExplanation=<strong>Adblock Plus will always block annoying ads.</strong> Still, we want to encourage websites using plain and unobtrusive advertising.

+firstRun_legacySafariWarning=The version of Safari that you are using is pretty old and full of bugs. So besides other issues, Adblock Plus might not work correctly or will even break some websites. We strongly recommend to <strong>update to Safari 6 (OSX 10.8) or higher</strong> if possible, or to use the latest version of an other browser, like Firefox or Google Chrome.

I'd put this a bit differently. It's probably sufficient to say that this
version is unsupported, that the oldest supported version is Safari 6 and that
it comes with OSX 10.8.

Urging users to update might not help much, a browser update is easier done than
an OS upgrade, which is what's necessary to get a newer Safari version.

That's why I alternatively suggest to use Firefox or Google Chrome instead,
which are both available for OSX 10.6 and Windows XP or higher. So almost all
users that see that message could just migrate to the latest version of Firefox
or Chrome.

That's true. How about making it more polite though? :D Here's my suggestion:

You are using an old version of Safari which is not supported by Adblock Plus,
so it might not work correctly. We strongly recommend to either update to Safari
6 (available in Mac OS X 10.8, Mountain Lion) or to use another browser, like
Firefox.

I agree that the wording of the message could be a little nicer, but I  have
some suggestions regarding your text:

1. The issue with the beforeload bug (why we actually added the message) isn't
that Adblock Plus will not work correctly (though that might happen as well due
to other issues), but that other websites will break when an extension registers
a beforeload listeners, like we do.
2. You refer exclusively to Safari 6 and OSX 10.8. So the user might think that
he needs exactly this version of Safari and OSX. But what we actually mean is
that he should either update to that version or any higher version.
3. The user might dislike Firefox, but might not be aware that ABP is also
available for Google Chrome and Opera. So we might want to list all other three
browsers for OSX that we support.

So what would you think about following text for the warning?

You are using an old version of Safari which is not supported by Adblock Plus.
So it might not work correctly or impair the user experience on some websites.
We strongly recommend to either update to Safari 6 or higher (available since
Mac OS X 10.8, Mountain Lion), or to use the latest version of Firefox, Google
Chrome or Opera.
