Frequently asked questions

Can I install Mailtrack and Checker Plus for Gmail™ at the same time?

Yes, Chrome runs them independently. Keep both only if they do different jobs; if they overlap, pick one, because each active extension adds memory use, page scripts and another set of permissions.

Where do the ratings and install numbers come from?

From each extension's public Chrome Web Store listing. They can lag the live store slightly, and a dash means the figures have not been synced yet.
