For this I use Simple Tab Groups: https://addons.mozilla.org/en-GB/firefox/addon/simple-tab-groups/ https://addons.mozilla.org/en-GB/firefox/addon/simple-tab-gr... I have a "Work" group that I switch to when working, and separate groups for the different personal projects I'm working on. That ensures that my tab bar only has the tabs relevant to my current context, while being able to easily switch back to the previous context and I pick up that work again.
