Tab Manager and Session Saver for Firefox: Save Your Tab Context Between Sessions

Tired of losing your work when you close tabs in Firefox? Tab Manager and Session Saver is an extension designed to help you save your current tab context and restore it later. This tool addresses the issue of multiple open tabs, which are often open due to ongoing work, rather than being forgotten bookmarks. With Tab Manager, users can save a snapshot of their open tabs, each labeled as a separate session, associated with a specific context.

Each session is a group of tabs linked to a particular task or context. For example, while researching a client project, you might have 12 tabs open, including competitor sites, a Google Doc, GitHub issues, reference articles, and bookmarks. To switch projects, simply save the current session, name it, for instance, "Client A - Research", and close all tabs. When you need to return to Client A project, restore the saved session, and all 12 tabs will reopen exactly as they were left.

Unlike bookmarks, which are for saving sites for future reference, sessions save work-in-progress contexts, capturing the exact set of tabs you had open, including their current state. This feature is particularly useful when returning to a project, as it allows you to pick up exactly where you left off without the hassle of reorganizing tabs. You can have multiple sessions simultaneously, each saved independently and restorable with a single click.

For added privacy, sessions are stored in Firefox's local extension storage and are not uploaded anywhere, ensuring that no account is required and no data is exposed. However, there are some limitations: sessions are stored only in local storage, so they cannot be synced across devices. Moreover, Tab Manager does not capture scroll position or form state, and it is not designed to organize tabs within a session; it merely saves the set of URLs.

To install Tab Manager, simply add the extension to your Firefox browser from the Firefox Add-ons page.
