    // and text colors equal to some CSS variables. it uses --tooltip-bgcolor,

    // the identity icon is missing tooltips and/or identifying icons for
    // several states. in particular, there is no tooltip on pages with mixed
    // content. on these pages the identity icon generally shows a lock icon
    // with a warning sign on it. so this is the intermediate state between
    // "secure" and "not secure." both of those states have their own special
    // tooltips but the mixed security state does not. (see
    // https://bugzilla.mozilla.org/show_bug.cgi?id=1736354) this is unfortunate
    // because the mixed state is actually a composite of several states. in
    // vanilla firefox, you currently can't tell which one without clicking the
    // identity box to open the popup. hopefully this feature will be added to
    // firefox but for now we can add it ourselves. we add tooltips so the user
    // can distinguish between blocked active content, loaded active content,
    // loaded passive content, weak cipher, or untrustworthy certificate. we
    // also add tooltips to show when the user had HTTPS-only mode enabled but
    // the site failed to load over https. there's also no tooltip to show on
    // chrome UI pages or local files. hovering the identity icon just shows
    // nothing. so we add these as well, so that it should say "This is a secure
    // Nightly page" or "This page is stored on your computer" in a similar way
    // to how it already shows on extension pages. While working on this I
    // noticed that some types of pages are missing a unique class, which means
    // they can't be given a unique icon. these pages are about:neterror and
    // about:blocked. the former shows under many circumstances when a page
    // fails to load; the latter shows when the user has blocked a specific
    // page. if you use duskFox you might have noticed that the theme adds
    // custom icons for certain error pages. previously this was just the
    // HTTPS-only error page and about:certerror (shows when the certificate has
    // a serious problem and firefox won't load the page without user
    // interaction). we couldn't include these other error pages because they
    // were just marked as "unknownIdentity" which is the same as the default
    // class. so I couldn't style them without styling some perfectly valid
    // local or system pages too, such as those with chrome:// URIs. so I'm
    // extending the icon-setting method so it'll give the icon a unique class
    // on these pages: "aboutNetErrorPage" and "aboutBlockedPage" which are
    // pretty self-explanatory. they still keep .unknownIdentity, they just get
    // an extra class. so you can style these yourself if you want but duskFox
    // already styles them just like the other error pages — with the triangular
    // warning sign.

    // engine urlbar result's icon. my theme increases the prominence of the
    // "type icon" in urlbar results. for bookmarks, this is a star. for open
