Keep the records you still have
Export accessible sessions before removing the extension or clearing its storage. If only a few tabs fail, copy their original addresses and try those directly. A working URL helps distinguish a restoration problem from a page that is no longer available.
Narrow down the failure
Record the browser and extension versions, whether the problem affects all tabs or a subset, and whether it also happens with a small new Session. Avoid sharing private addresses in public bug reports.
Consult Tab Session Manager’s issue tracker for matching reports. Recent user reviews describe restoration trouble, but a review does not establish its cause or a universal repair.
If you decide to move
Nest includes Tab Session Manager import. Keep the original export, inspect the import preview and restore a small sample before moving the rest. An importer cannot recover records absent from the source file.
Compare the two products’ workflows. Tab Session Manager remains relevant when its open-source model or Firefox support is essential.
Keep your browser work within reach
Nest saves Sessions, restores Chrome tab groups and helps you return to your work. Three named Sessions free; unlimited Sessions and cloud sync on Pro.
Frequently asked questions
Will reinstalling recover saved sessions?
Do not rely on it. Preserve accessible exports first because removing an extension can remove its local data.
Can Nest fix a corrupt export automatically?
No such guarantee is made. Verify the preview and keep the original file.
Should I switch immediately?
First preserve your data and identify the failure. Change tools only after verifying the workflow you need.
