I'm taking nightly incremental backups of /home for example to my home storage server and, I guess, due to the databases Firefox uses for various storage, those can't be backed up by just copying them, if Firefox is running and has the database open.

What are the best practices, then, for ensuring all profile data, including these databases, is in a state where it can be backed up, while Firefox is running, in a way it can be restored to a fully functioning profile?

For example, with MySQL databases, you can dump the log before running the backup each night, which basically exports the SQL statements needed so you can skip backing up the actual binary database file (like ibdata1).  Does SQLite need something similar?  and is this the only special consideration that is needed, or are there other specialized types of data within our profile directories that can't be backed up by simply copying the data while Firefox is running?

Thanks

I am 80 years old, and ot a computer genius. This morning after loading up normally, tabs kept crashing on firefox. I the got a notice to restart for a windows update. After the restart Firefox disappeared, and I had to reload it, but I lost all my previous settings.

Hi team,

please help as I lost all my bookmarks I received this message and now i cannot see none of my bookmarks or extensions. "Firefox is already running, but is not responding. The old Firefox process must be closed to open a new window.

Problems with Firefox. Quite often it won't show an image or video. Switch to a different browser and the page looks good. Can I retore Firefox to its initial values without uninstalling ? Why do they keep making changes, seems like I am constantly having to make changes to keep all working. '

I had a computer crash. Restarted to restore point from earlier in day. FireFox would not start. Successfully restored FF on desktop; restored passwords; restored profile from saved profile. FF is working but the Win 11 list of apps shows both the current FF and a grayed-out FF. There is also a FF Private Browsing app. How do i get rid of the grayed-out FF. Pete

Tried to include a screenshot, but there doesn't seem to be that option.

Hi - Wondering if anyone has ideas on how to fix this and recover my bookmarks:

1) Had to reset my Windows 10 laptop which uninstalled Firefox. 2) When I reinstalled firefox and logged into my account, none of my extensions, bookmarks downloaded or synced 3) I synced my phone (logged into my account correctly with my data) to the firefox on my computer (via QR code), hoping that would fix my laptop's browser syncing issue. Instead it deleted all my phone's firefox bookmarks when it synced with my computer (ugh!)

Is there a way to recover my bookmarks from my phone's firefox or they are all lost? My phone's firefox still has the history but no longer my bookmarks.

Thanks!

5th Nov 2024 Hi, Firfox has just (few hours ago) updated.. It has 'lost' ALL of my (several years of) PASSWORDS, BOOKMARKS and HISTORY I have tried the fixes given on the forum,. but there doesn't seem to be anything there to recover. And frankly the whole 'other profile' thing confused me.

Can anybody help please.. ?

Thank you Phil

I had recently reset my laptop which removed all apps including firefox. All my passwords were saved in Firefox and I had no backup. After reset, when I reinstalled firefox and signed in. To my surprise, all my passwords and bookmarks were gone. I thought I'll get them after synchronization but nothing. That will be a big issue for me, can anyone help me get atleast my passwords back?

Good day,

Firefox Synchronization restores my old data as soon as I sign in, even though I do not push synchronization.

I have absolutely no power to decide what gets restored. I do not see any possibility to update the data stored on my Firefox profile online.

But the oddest behavior is that I opened a new account from another PC in order to save my actual Firefox data. I then synchronized my data from the first PC with the new account, and this time, instead of overwriting my local data from my new account, it is the data from the new account that got overwritten from my local profile containing the old data.

To sum up things, it seems that:

- I cannot choose what gets saved or restored neither on my PC locally nor on my Firefox profile online.

- When I synchronize Firefox, my data gets randomly overwritten either on my PC locally or on my profile online, without giving me the choice to either backup or restore these data.

Is there any way to avoid this ? And how do I choose if synchronization overwrite my local profile from my online one or the other way round ?

I downloaded new version, cause it didn't update automatically. Selected to sync everything. Now I have 2 browsers on my PC! The old one works bad, the new one synchronized just 5 passwords randomly. I tried to sync the tabs with my phone, still not workinng. What can I do to solve this?

I often use the Sync function to bring open tabs over from my smartphone to my desktop computer. I have noticed over the past month or so, this functionality has become increasingly unreliable and sometimes does not function at all. At the moment I have no synced tabs showing on my desktop. I have signed out and back in to Mozilla on both my smartphone and desktop multiple times, checked the sync settings, and nothing seems to resolve this. There have been a couple Firefox updates on both the desktop and mobile side, none of which have changed this behavior.

Has anyone else been experiencing this? What other trouble shooting steps can I perform? Any help is much appreciated.

Hello,

I would like to ask if there is something that can be done to recover bookmarks/logins?

The story: 1. When opening new tab it says it needs restart for a new upgrade. 2. Then nothing happens. When trying opening firefox new window does not load, the process shows for a short time (few seconds) then disappears. When opening it from cmd there is no console log. 3. Then after reading internet, it said that reinstallation could help. I did that, i.e. installed new firefox installator and ran it. After opening, it was a brand new firefox, no bookmarks, login information loaded from existing profile. 4. Tried to recover profile information via sync, but to my unfortunate i reseted the password from mozilla account and login in new mozilla firefox thinking it would fech all the data from server and I could retrieve my history. Unfortunately after the fact I read that it would reset all stored information on that account. 5. Right now in Profiles folder I can see three entries, two of which have only parent.lock file and the other is this brand new profile. I assume/guess it was created during reinstallation.

When going to update history it shows "Install Failed" on Firefox 132 version.

Is this case totally lost and all data is unrecoverable or is there a chance to recover it? When reinstalling, does new installation create a new profile that is futher used or try to use one that was used by already installed Firefox? Has the local profile been overwritten when resetting account password?

I understand that I made few mistakes along the way, e.g. not backing up profiles when upgrade failed, but nevertheless I would like to ask if there is anything that can be done?

Thanks

imported my bookmarks from an HTML file but cannot save new bookmarks to the old folders. The folders are there when I look using the 'Show your bookmarks' icon. I can access bookmarks from this icon.

When I try and bookmark a new site the imported bookmark folders do not show up. Help please.

The latest version destroyed my browsing history and all of my opened tabs are gone! The currently shown history is not of my laptop but from my desktop and my phone. I lost all of my laptop history. How can I restore them? Are the backups not affected by the new version and where can I find them?

Today I was filling in a contract with a government organization. The type that allows me to answer questions and submit. I clicked on something else before finishing and I could not retrieve my work.

I have tried ALL of the suggestions available in HISTORY (restore previous session) open closed tabs etc Etc.

Nothing works
