(Do not use container managers read more) This is an excellent program or extension to save yourself from constantly switching accounts — it automatically does it for you across many platforms. It’s one of the best tools I’ve used, especially since one of my legitimate innocent accounts was banned form YOUTUBE and kept causing issues. This application fixes that by automatically logging into the correct Google and other accounts with perfect timing and reliability.

Please note:
Do not use container managers. If you’re using a container manager (for example, YouTube Container Manager, Google Container Manager, or similar) while trying to log in or automate account switching, it will not work. Container managers override these functions.

The extension was considered as an alternative to the extensions "Default Account for Google products" and "G-Switcher". Unfortunately, in Mozilla Firefox 142.0 (64-bit) under Microsoft Windows 10.0.19045.6216, when you click "Add rule", a white dialog is displayed without inscriptions and buttons.

Upd. v0.4 (2025-08-15) — same. Is there any way I can help diagnose the cause of the problem?
