Simple Tab Groups review
A free, open-source Firefox extension for flexible tab grouping and session organization.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Simple Tab Groups is an open-source Firefox extension for people who need to organize many tabs into separate browsing contexts. It lets users create, modify, organize, and quickly switch between tab groups, including groups spread across multiple Firefox windows. Search and filtering make larger collections easier to navigate, while custom group icons, tab icons, drag-and-drop controls, and sidebar access provide several ways to manage browsing sessions. The product is aimed at individual Firefox users who want more structure than a single browser window can provide.
Pricing is straightforward: Simple Tab Groups is free, with no paid tiers described. Its core organization features include group creation and switching, multi-window management, tab search, workspace support, and session restore. Backup and restore are handled through JSON files that can contain tabs, groups, and settings, giving users a portable way to preserve their arrangements. The published feature set suits users who want practical tab organization without adopting a paid plan or a larger productivity platform.
Firefox integration is the product’s strongest ecosystem fit. Simple Tab Groups works with Firefox Multi-Account Containers and lists integrations with Gesturefy, Create new group, Create new tab, Group notes, and Load custom group plugins. That makes it a good choice for users already working within Firefox’s extension model and looking to add group-focused workflows. It is less suitable for people seeking a browser-agnostic tab manager or a broader cross-platform workspace system. Choose it for flexible Firefox tab groups, JSON session handling, and plugin-supported customization; consider an alternative if your workflow depends on ecosystems beyond Firefox and its listed integrations.
