Latest reviews

  • (2025-07-11) Dave Mitchell: The latest update to remove GTM injection is a disaster. I was using that feature everyday in my job to build containers for clients. Is there anywhere to download a version of the extension that still has it?
  • (2025-06-04) David Guerreiro: It was great but it does not work anymore in the most recent version
  • (2025-04-28) creative ideas: Excellent plugin. Really helpful.
  • (2025-04-23) Lim Soon Yi: Hello, may I know when will have the GTM injector function back again. Previous versions have this function and it helps me a lot in troubleshooting. If the functions are not available in the short-term, may I know is there any method that I can use the previous version temporarily?
  • (2025-04-16) Andrii Yashchenko: Big thanks for the update; because of the new API in Chrome, the previous version was deprecated and removed. I had to find other alternatives, but they are all terrible compared to this extension! It works perfectly so far.
  • (2025-04-09) Steven: Stopped working after the update. Just keeps on loading god knows what. They decided to revamp the whole thing and at the same time remove some features which I frequently use. Awful.

  • (2020-12-10) Stephen Akins: Okay... so some items are blue and some are grey. What does that mean? Are things as they should be? Should some be blue that are currently grey? Aren't there any possible comments or advice?

  • (2019-01-28) Was very useful, but currently breaks DataStudio and makes it unusable (Data Studio reports don't load anymore). To dev: See console while opening a google data studio report for debug info.
  • (2018-07-10) Consuelo Sanders: Agree it's a useful addon and been using for a while now. However the latest release has started throwing "Script Error" errors when working in Salesforce marketing cloud - the error keeps popping up and no way to disable - have had to remove the addon completely to be able to work. Error details: Script error. url: line: 0 col: 0 Script error. url: line: 0 col: 0 Script error. url: line: 0 col: 0

  • (2018-05-07) Clark Frye: Useful add-on, however this addon causes a problem in Google Sheets where I'm unable to modify ANY Google Sheet. When the addon is enabled, I get a message in Google Sheets which says "Unable to load file. Try to load it again or send an error report." Uninstalling the addon fixes the problem.
