This started since Firefox 153.0 (Debian package).

When I open Firefox for the first time after a reboot, it opens my latest tab but all the other tabs on that window are lost, and they show as "ghost tabs" as seen in attached image.

No other issue, other windows are preserved properly when I Ctrl + Shift + N

I have tried restoring my bookmarks using these steps but it doesn't work. Specifically, when I try to select "Choose File" in Step 3 nothing happens. The option will highlight, but when I click on it no window to choose a file pops up. Is there any other way to restore bookmarks using a json backup?

After opening up Firefox to continue work in one of my Saved tab groups, I noticed the 153.0 Update window.

All my saved tab groups have been deleted and the tab group options have been replaced with the new Tab container system in the drop down menu. I even made a new group to test and it saved and was accessible but all the important ones are gone. Nothing in the Json files, tried most of the solutions I've read online. none of these work.

Saved Tab groups don't to sync across devices and are local, so surely they should be saved locally on the system.

Synced tabs from Android device gone after ~3 weeks — need definitive retention policy

Hi,

I had Firefox tab syncing set up on my phone, and the synced tabs were showing up fine on my other devices for a while. About 3 weeks ago, that phone was lost (long story — it ended up in a river) and I haven't been able to sync from it since.

Now the synced tabs from that device are no longer showing up on my other browsers, and I need to recover some important information that was in those tabs.

A few specific questions:

What is the current official expiration policy for synced tabs data (as of 2026)? I've found conflicting info in old forum threads — anywhere from 1 week to a year depending on platform and Firefox version. Is there any way to see whether my account still has cached tab data for a device that's been disconnected/inactive for ~3 weeks, even if it's not displaying in the normal Synced Tabs view? If the tab data has expired, is there any other server-side record (even temporarily) that Mozilla could check on the account side that isn't visible to me as the end user?

Any help checking the account status directly, or clarifying the actual current retention window, would be a huge help. For my email address, please request below.

Thanks, Ebe

Safest way to migrate firefox bookmark/Login data from external HDD to new PC firefox profile

My old laptop died, stranding my Firefox profile (including bookmarks and Login credentials for many sites). I am able to connect the old laptop's HDD via USB to port the old profile data to the new laptop, but I am afraid that copying the older files to the new profile will overwrite the newer profile data. I would like to create a second profile, in which to store the old data, in the newer laptop's instantiation of Firefox, but I don't see any information online about doing this. Is it possible to create multiple profiles in Firefox for this purpose? Thank you
