Conditional catch clauses - browsers support

What browsers support Conditional catch clauses?

On MDN try...catch you can find Conditional catch clauses as Non-standard feature.

try {
    myroutine(); // may throw three exceptions
} catch (e if e instanceof TypeError) {
    // statements to handle TypeError exceptions
} catch (e if e instanceof RangeError) {
    // statements to handle RangeError exceptions
} catch (e if e instanceof EvalError) {
    // statements to handle EvalError exceptions
} catch (e) {
    // statements to handle any unspecified exceptions
    logMyErrors(e); // pass exception object to error handler
}

Note: This functionality is not part of the ECMAScript specification.

It's supported by any modern browsers?

Google Chrome's console returned Uncaught SyntaxError: Unexpected token if

Or shoud I use:

try {
    myroutine(); // may throw three exceptions
} catch (e) {
    if(e instanceof TypeError) {
        // statements to handle TypeError exceptions
    }
    else if(e instanceof RangeError) {
        // statements to handle RangeError exceptions
    }
    else if(e instanceof EvalError) {
        // statements to handle EvalError exceptions
    }
    else {
        // statements to handle any unspecified exceptions
        logMyErrors(e); // pass exception object to error handler
    }
}
