Group Tabs On Desktop and Mobile

[Encrypted4D]

As a researcher, designer, and developer, I use multiple tabs which end up looking messy on my browser. I really wish there was a way to group each tab based on their use, give each tab specific colors for easy recognition, and also bookmark or pin groups for easy access when the browser is launched or relaunched.

I want to be able to group tabs as well! I use Chrome at work and I'm able to do that. I assumed I'd be able to do that on my personal computer in Firefox but sadly not. That would be such a great way to organize things.
