Features & Capabilities

Session Sync is a powerful Chrome extension designed to save and manage your browsing sessions by utilizing bookmarks. Unlike traditional session managers, it stores sessions as bookmarks, allowing seamless access, editing, and restoration across multiple devices using bookmark synchronization services like Firefox Sync or EverSync.

Key features include an intuitive user interface with multiple working modes (Panel, Tab View, Window View), advanced bookmark and session management, session filtering and sorting, lazy-loading session restore, customizable keyboard shortcuts, and advanced drag-and-drop UI. Session Sync also manages permissions efficiently, ensuring all your session data remains local or synced via your Firefox account. It is an excellent tool for users looking for versatile session and bookmark management that integrates directly with the browser's bookmark system rather than proprietary formats.

User Reviews

Users praise Session Sync as a simple, reliable session manager that syncs well and excels for research and large tab collections. Common complaints are missing features: no global title search, no multi‑selection of tabs, lack of automatic session saving, and no support for Firefox containers which can break restores.

Pros

Reliable and long‑lived — many users report it has worked for years and is their go‑to session tool.
Simple and easy to use — intuitive UI and fast workflow for saving and restoring groups of tabs.
Syncs across devices via Firefox/Mozilla Sync and lets you create collections of links for research.
Better session management than built‑in bookmarks/tabs — useful for research and large tab collections.

Cons

No global search by tab title (search is limited or awkward; Enter doesn’t always activate results).
No multi‑selection support (cannot shift‑select ranges of tabs or select many at once).
Does not auto‑save sessions by default (users expect automatic session saving).
Lacks Firefox container support — restored tabs can lose their container assignment and misbehave.

Recent reviews

this has been an extremely useful tab saver, compared to the other extensions, this one was the best experience for me, easy and efficient, the only issue, which is a big one, is it doesn't have a global search by title, which is frustrating, you kinda have to remember where you saved the tabs, it also doesn't allow multi-selection, i'd love the option of selecting a tab and pressing shift and select the other tabs and all the tabs in between get selected as well, right now you have to select them manually, and lastly no sort by doman or subdomain

Is Session Sync Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Session Sync requires a few sensitive permissions. Exercise caution before installing.

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Session Sync is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this add-on.
