Firefox Multi-Account Containers
Firefox Multi-Account contains are awesome for software development and testing! At my work we usually work at tools which have three roles: user, reviewer, administrator so I generally have three containers for these user accounts. This means I can be logged in with all the accounts I need for testing in the same web browser without resorting to private mode (which does not remember cookies between sessions anyway).In addition, I use the temporary container add-on[0] which also uses containers, but throws them away after being used (like reference counting).These two tools have seriously improved my ability to both develop and test applications without the hassle of logging out and logging in all the time or needing any tricks when needing multiple clean browsing sessions.[0]: https://addons.mozilla.org/en-US/firefox/addon/temporary-con...
