What Tab Session Manager is

Tab Session Manager is a free browser extension for saving and restoring browser windows and tabs. It can save automatically when a window closes or at regular intervals, and saved sessions can be organized with names and tags. The extension supports saving tab groups, importing and exporting sessions, and importing Session Buddy data. Cloud sync uses Google Drive to synchronize sessions between computers. By default, session data is stored locally and is not sent to an external server unless Cloud sync is enabled. With sync enabled, data is placed in the Google Drive App Folder, which the privacy policy says other apps and the maker cannot access. The maker links to Chrome and Microsoft Edge versions, while the Firefox listing says it is compatible with the Chrome extension. Firefox regular autosaving has a minimum interval of 0.5 minutes because of Manifest V3 limitations. An Import URL list feature uses Google’s API for favicons. A local compressor can reduce memory use for favicons in sessions saved by version 6.7.0 or earlier, and loaded files are not sent to the Internet during compression.
