Tab Stacks Lost | No Recovery

Bug Report # VAB-10576

All tab stacks lost - no way to recover

Title says it all.

All tab stacks disappeared, only a handful of unstacked tabs remained.

Doesn't seem visible / recoverable via recently closed / history.

Last chance if the session has remained synced in cloud and recoverable via desktop.

(EDIT: unlikely, desktop shows itself as disconnected from sync and now seems frozen for minutes after re-engaging sync)

Why?

Technically, not all of them are gone. You can get your last 5 tab stacks from the "closed tabs" menu, but only those ones, which seem to be chosen arbitrarily. The rest are just gone.

Still, though - MAJOR IMPORTANT BUG.

No, not in my case, there is no close at hand evidence of those tabs existing a while before

TheGoomba98

Really? Have you tried going to the tab switcher menu, then tapping the trash can at the bottom?

I'm afraid this has something to do with the recent sync fix, because my tab stacks aren't getting synched.

RadekPilich

It might be caused by sync in some odd way, but maybe more likely there is some other cause due to the recent changes to the tab stacks on mobile or some other bug in the app itself.

Same thing, I have a tab group with 130 tabs missing. At first I thought I may have closed it myself, but after I looked in my history of closed tabs, there was nothing there. The tab group just disappeared...

Hi, I can reproduce this on 7.0 stable but not in my internal 7.1 build.
I will try to find a bug report.

Same here
Android 10

V Stable | 15 Tabs -->> 2 Tabs | 3 Stacks partially recovered

V Dev | 211 Tabs -->> 93 | Just 2 Stacks available to restore

Dev is snapshot?
I asked in the developer chat but it's weekend and vacation time, as usual.

@RadekPilich I have lost my 200+ Tab. It's very frustrating. I can't tolarate this major bug.

I ditched Firefox for Vivaldi. But Vivaldi has become very unreliable.

@abnanik Firefox with container is very good on desktop tbh but the issue is their engine on mobile is pretty crap. For that chromium is simply the best solution

One device more.

Huawei Mate Pad 10.4 | Android 10 | HOS2
From 215 Tabs with Stacks -->> 56

Just 4 Stacks in the Bin to recover

Sync still appeared as disconnected, had to add the Encryption key to fully reconnect, so the lost Stacks and tabs problem appears right before.

Is there any way to restore them? I have regular backups of my phone's storage, including the private app data, but it seems tab stacks aren't part of the Default/Sessions/Tabs_* files? I lost 5-7 stacks with over a hundred tabs, which is a huge annoyance for me..

Hi, on desktop it is.
Don't copy the folder Sessions over the existing, this doesn't work.
You have to delete the existing folder then copy it over.
I have no rooted device so I cant test this on mobile.

Hi,

Copy the full data folder to Desktop
Keep it
Learn about the Sessions and Workspaces on desktop
Check on the saved Mobile folder
Create a New Profile on Desktop and paste there the sessions / Workspaces files

Thanks for the replies.

I first deleted the existing Tabs_* files and replaced them with the ones from the backup. Unfortunately, while the unstacked tabs were there, the stacked tabs were still missing. I don't see them in "recently closed" either. I tried restoring them both on my phone as well as within a new profile on my computer. For what it's worth, the mobile backup doesn't have any Session_* files in the Profile/Sessions folder. I don't know whether that's intentional.
