I found this awesome new add-on for Firefox called Firefox Multi-Account Containers. As an IT guy, it is very helpful. Using this Firefox container you can log into the same website with multiple accounts without using another browser. In the past, I would have to open another browser like IE or Chrome in order to log into the same site with another account. After I found this I asked some IT friends and no one even knew about Firefox containers! So I decided I had to share this.
I think Chrome has something like this called SessionBox that lets you log into multiple accounts on the same site simultaneously. If you love Chrome you may want to check that out but for me, I love Mozilla Firefox so I would rather stay in Firefox if I can help it.
How Firefox Containers works
First you need to install the add-on. This only takes a second.
After it has been installed you will see a new button that looks something like this.
When you click that button you will see something like this.
You can add and label containers however you like then you just click on one to start a new session inside your Firefox. You will notice that the tab has a color-coded line that tells you what container you are in.
Now inside the color tabs, you can go to office365, Twitter or whatever and log in with another account. This has come in handy a lot for my job and I have fallen in love with Firefox containers! And if your interested another add-on that has come in handy to me is Firefox text to speech!
