Where Does Sidebery Store Panels and Sessions?
Sidebery keeps sidebar panels, containers, and sessions in per-profile Firefox extension storage.
Last updated
Sidebery stores its world in Firefox extension storage inside the active profile. Sidebar panels, container assignments, saved sessions, and settings share that space. There is no external session file.
Container tabs complicate manual moves, since container identities live with the profile too. The in-extension backup captures both halves together. Restore order matters less than completeness.
Where Sidebery stores this, by platform
%AppData%\Mozilla\Firefox\Profiles\<profile>\storage (per profile)
Panels, containers, and sessions per Firefox profile. In-extension backup plus settings export covers moves. Profile loss without backup is final.
~/Library/Application Support/Firefox/Profiles/<profile>/storage (per profile)
Same storage model on Mac. Restores rebuild panels and container assignments. Export before profile wipes always.
~/.mozilla/firefox/<profile>/storage (per profile)
Profiles under ~/.mozilla with the same backup workflow. No cloud copy exists. Sidebars belong to the profile that grew them.
Frequently asked questions
How do I move Sidebery to a new profile?
Use the session backup and settings export, then restore on the new profile. Panels, containers, and saved sessions travel together. Fresh installs start with default panels.
Does Sidebery sync across devices?
No. Everything lives in that profile's extension storage. Losing the profile without a backup loses panels and sessions. Export regularly if the sidebar runs your workflow.
