Is tabVertikal - vertical tabs safe?

Low risk

tabVertikal sends side-panel JavaScript error details and browser user-agent data to bug-collector.noterail.workers.dev.

The extension's side panel registers handlers for JavaScript errors, unhandled promise rejections, and console.error calls. When one occurs, it posts the error message, stack trace, extension ID, extension name, extension version, timestamp, and browser user-agent string to its bug collector endpoint.

Part of this rating comes from analysis signals we haven't published as detailed findings yet.

Where it sends data

Destinations our analysis observed tabVertikal contacting. Sending data somewhere is not a finding on its own - an extension that syncs your settings has to talk to its own server - but it is where your data can go, and who else it goes to.

  • bug-collector.noterail.workers.dev
