Taoufiq Ait Ali 2025-09-23: was great but not work anymore. keep loading
Dave Mitchell 2025-07-11: 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?
David Guerreiro 2025-06-04: It was great but it does not work anymore in the most recent version
creative ideas 2025-04-28: Excellent plugin. Really helpful.
Lim Soon Yi 2025-04-23: 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?
Andrii Yashchenko 2025-04-16: 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.
Steven 2025-04-09: 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.

Stephen Akins 2020-12-10: 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?

Miljenko Bulaš 2020-09-21: Works! It would be awesome if it could add "events" in real time, without having to open and close the window (like GTM does).

Anonymous 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.
Consuelo Sanders 2018-07-10: 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

Clark Frye 2018-05-07: 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.
