Is Get Google Tag Manager Size safe?
Get Google Tag Manager Size watches pages for GTM script requests and stores container size and timing details locally.
When a page loads a Google Tag Manager script, the extension reads request and response details, fetches the script to measure its size, and analyzes container tags, triggers, and variables. It caches those results for the tab in chrome.storage.local and displays them in the side panel; the reviewed source did not show the captured browsing or container metadata being sent to an external recipient.
