I have been using multi-account containers to separate browser cookie sessions, and have been looking for a way to open collections of links in a single click.

This workflow is particularly useful to me after a fresh start of the browser (beginning of the day, or after a crash) to quickly open the web pages I use for work

My plug-in "DashBox" implements opening sets of links into separate "Multi-Account Containers" to isolate cookie sessions. This leverages the "Multi-Account Containers" Firefox plugin from Mozilla [1]

It is useful for me, and I am sharing it so it may be useful for others

Alternatives may be:

- Chrome browser: separate profiles, use the "Settings -> On Startup -> Open a specific page or set of pages"

- Firefox browser: separate profiles, use the "Settings -> Home -> Homepage and new windows" setting to "Custom URLs" and provide multiple URL's there
