I love Tab Stash!!! The grouping is insanely useful when I'm working on a research-based project for uni. The vertical sidebar makes the names of tabs readable, eliminating the need to jump between tabs trying to find a specific one when you have too many. I love that I can rename groups and tabs, and collapse groups and the sidebar. You don't even need to stash your tabs to use tab stash as your tab manager! This is way better than the built-in tab and bookmark managers. I've moved all of my bookmarks over to stashed tabs-- it allows me to see them way easier, keep them grouped, and access them quickly and easily. Reorganizing your stashed tabs takes only a quick second to click and drag, and closing or opening a large number of tabs is simple, easy, fast! I love Tab Stash. I do everything in Firefox instead of Chrome just because of Tab Stash. I tell all my friends to use Tab Stash. I keep it open in my sidebar incessantly when I need to manage a number of tabs. Tab Stash FTW!!!!
