Whitelisting the new tab page on your adblocker ensures we can show you ads on Tab for a Cause (and that you raise money for charity). Please visit and follow the instructions on this page: https://tab.gladly.io/adblockers/
Please note that there are a few adblockers that are not compatible with Tab for a Cause at the moment. Ghostery, Adguard, and Avira do not work on either browser, Adblock Plus is currently not working on Firefox (though should be fixed soon). If you are currently using one of those adblockers, we can highly recommend Ublock Origin as a free, open source, and fast adblocker that works well with Tab for a Cause.
