    Are you running this extension on pages outside the salesforce domain or only in salesforce domain? If You're running it only in the salesforce then you can use the sessionId stored in the browser cookie to make REST callouts. But if you're using on pages outside salesforce domain then you can authneticate using oAuth2.0.

Use the chrome.identity API methods. For example:

chrome.identity.launchWebAuthFlow(options, function(redirectUri) {
            if (chrome.runtime.lastError) {
                return callback(new Error(chrome.runtime.lastError));
            }

            // Upon success the response is appended to redirectUri, e.g.
            // https://{app_id}.chromiumapp.org/provider_cb#access_token={value}&refresh_token={value}
            var matches = redirectUri.match(redirectRe);
            if (matches && matches.length > 1) {
                handleProviderCodeResponse(parseRedirectFragment(matches[1]));
            } else {
                callback(new Error('Invalid redirect URI'));
            }
        });

        function parseRedirectFragment(fragment) {
            var pairs = fragment.split(/&/);
            var values = {};

            pairs.forEach(function(pair) {
                var nameVal = pair.split(/=/);
                values[nameVal[0]] = nameVal[1];
            });

            return values;
        }

        function handleProviderCodeResponse(values) {
            if (values.hasOwnProperty("code")) {
                var url = host + '/services/oauth2/token' +
                    '?client_id=' + clientId +
                    '&client_secret=' + clientSecret +
                    '&grant_type=authorization_code' +
                    '&code=' + values.code +
                    '&redirect_uri=' + encodeURIComponent(redirectUri);

                var xhr = new XMLHttpRequest();
                xhr.open("POST", url, true);
                xhr.onload = function() {
                    if (this.status =300) {
                        callback(new Error('error in handleCodeResponse.'));
                    } else {
                        handleProviderTokensResponse(JSON.parse(this.response));
                    }
                };
                xhr.send();
            } else {
                callback(new Error('error in handleProviderCodeResponse.'));
            }
        }

        function handleProviderTokensResponse(values) {
            if (values != null) {
                callback(null, values);
            } else {
                callback(new Error('error in handleProviderTokensResponse.'));
            }
        }
    };

    module.refreshToken = function(connection, callback) {
        var url = connection.instance_url + '/services/oauth2/token?client_id=' + clientId +
            '&client_secret=' + clientSecret +
            '&grant_type=refresh_token' +
            '&refresh_token=' + connection.refresh_token;

        var xhr = new XMLHttpRequest();
        xhr.open("POST", url, true);
        xhr.onload = function() {
            if (this.status =300) {
                callback(new Error('error in handleCodeResponse.'));
            } else {
                handleProviderTokenResponse(JSON.parse(this.response));
            }
        };
        xhr.send();

        function handleProviderTokenResponse(values) {
            if (values.hasOwnProperty('access_token')) {
                callback(null, values);
            } else {
                callback(new Error('error in handleProviderTokenResponse.'));
            }
        }
    };
