(1) If zoom breaks the layout, you might be using "Text Only" zoom. To switch to "full page zoom" you can:

(2) The forum software detected your Firefox as version 12. Is that correct?

Version 12 is not secure; Mozilla discloses security flaws after each new release. Is something holding you back from upgrading to Firefox 22? Please let us know so we can suggest solutions or workarounds.

If Help > About Firefox shows Firefox 22.0, you may need to clear the preference that is misreporting your version number. See: How to reset the default user agent on Firefox.
