Firefox Support Forum

I have lost all homepage tabs, add-ons, cookies, last pass info, etc. Last security update was April 7 2015. Not sure it is relevant, but at least coincidental w/ occurrence of my problem Can I recover?

I looked at "synch" but not sure it applies to me. Using only 1 laptop with Windows 7.

Thanks!

Hello,

I've been using my own Sync 1.5 server since January without having any issue until this week.

I am unable to sync my clients, getting the "Sync encountered an error while synching: Unknown error, Sync will try again automatically."

Here's the log: https://pastebin.mozilla.org/8836193

The problem seems to happen at line 101 (on pastebin).

Here's some more info about my setup.

Syncserver 1.5.2 installed on a local server running on Linux.

I have 1 Windows client, 2 Linux clients. None of them can sync. All uses Firefox 38.0.

Any help would be appreciated. Thanks, Phil

Firefox removed all my stored passwords, and this is going to be a huge problem for me.. They were all in Firefox password manager, or whatever its called, and i tried to lookup logins.json in %appdata%, but it only shows the last password in the list (i had only added a new one when i found out all old ones were gone-made an account at a new site before going through old ones).. The logins.json does not show a rollback history(previous versions)..

I think the fonts etc look different now than it did yesterday, so it could have been an update during the night? Either way, how can i restore it??

v54.0.1 -32bit

I recently had a power failure, which meant that Firefox didn't close down properly when the PC powered down. When I restarted, Firefox had lost all of my previous settings, ie bookmarks, passwords etc, so I have tried to recreate a profile which contains all of the previous elements. However, there is clearly something wrong & although I have deleted the places files & run the "Refresh Firefox" utility, these continue. My main bugbear at present is that I cannot either backup my bookmarks file, or export it in HTML format, in order to even consider creating a brand new profile. I have also noticed that my new profile has a bookmarksbackup folder, but is never getting populated with any content. I do have an old profile which I have used to recreate the profile that I am using now, but I am beginning to wonder whether there is some sort of corruption in the files contained, which means that I am simply recreating the problems, over again. I have a number of other quirks & eccentricities, ie the clear downloads button doesn't always work & all of the small icons on my bookmarks have disappeared & show no sign of refreshing, even though a week has elapsed since the original "crash". So, are there other files that I need to delete / recreate in my profile, in order to get back to normal functionality ?? As I say, my biggest current problem is not being able to backup or export my current bookmarks file - it says that it is being done, but no files are actually created. Oh, and I can create new bookmarks, but once again, the small icons which use to be created, no longer appear. Many thanks for any assistance out there.

Any tab I wanted to open simply wouldn't, so I Thought I should restart Firefox with the Add-ons disabled. By mistake I chose Refrsh, and now everything is gone. Bookmarks and Add-ons. I've already read the relative questions and answers, no help there. I need this resolved fast, it's like I've never used a browser before.

After 58.0.2 installed itself on my Windows 10 computer, all my bookmarks and passwords disappeared. After rummaging around the web, I found a way to recover my bookmarks, but none to recover my passwords. Is there a way to do this? Thanks.

hi all mozilla did an update today and now all my saved logins and passwords have disappeared. I googled a few answers and it states to delete this file secmode.db. I cant find this currently. I have also been using mozilla firefox account which supposedly saves the details somewhere. Can anyone please point me in the right direct step by step to recover these missing logons details or how to restore them please.

I am running Win 10 with Firefox v58.0.1

Every day, at least once per day, I loose about half of my bookmarks. Most often it happens overnight, when I come back to my desktop in the morning. I rarely shutdown at night, just leave everything up and running. When this happens, I have to go to "import and backup"/restore/then pick a restore date and reinstall the bookmarks. I always get a message afterwards saying "Unable to process the backup file", but the bookmarks are restored.

Today, I must have lost my bookmarks at least four times. What can I do to stop this from happening? It is a time waster and annoying.

Turned on my computer, loaded Firefox and bookmarks gone. Backup gone. No updates or changes. Worked fine and all there prior to shutdown last use. Restarting computer - no change. Scanned - no viruses/malware. Other user, my wife still has hers, just mine are gone.

Where are they and how do I get them back? Why are they gone?

My laptop just started up and Mozilla updated automatically to newer version 58.0.2 (64-bit). All bookmarks and previous data is missing. Just checked files under the program's folder and all previous data is gone from there too. I want to retrieve my previous data, so please any advice is welcome

I recently downloaded a site that erased my passwords. I have removed that program, but the password memory in Firefox is not working as it did prior to that. How do I turn on or off the automatic sign in that was working? Thanks - Dawson

Something happened and all my bookmarks are gone and the old Firefox data folder on my desktop was deleted by accident. I have looked everywhere and done system restores. How do I get them back? Does Firefox support offer screen sharing support?

Running firefox 45.7.0

My bookmarks have disappeared from the browser, but the library --> import and backup --> restore shows backups from the past many many days. However, when I try to restore from a backup, I get an error that says "Unable to process the backup file."

I know this Q was asked recently but I cannot follow the disjointed and part missing thread. Would appreciate if someone could give me a complete reply. I know how to display hidden files and find my Application Support folder but profile files are all several years old. I have up to date Time Machine backups.

I am running Firefox 58.0.2 on OSX but inadvertently ran Firefox 34 and now my v58 has lost all history and bookmarks.

All my bookmarks and saved logins are disappeared. It's more like I'm trying firefox for the first time, showing me top sites and search box and ..., I run Microsoft update, then I've been asked for restart, after restart I see nothing in my Firefox , I would appreciate it if you could help me back my saved logins and also all my bookmarks.

When my computer updated last night, firefox developer edition updated.

When I logged in to my normal edition it had lost all its history, bookmarks and settings.

These had all been taken over by the developer edition.

Is there any way to get these back.

I guess after the recent Firefox update, my old bookmarks were wiped out. I went through the process to restore old bookmarks, but the options only included bookmarks dated since after the update, with no dated files from before the update. I think the instructions stated that there should be 15 backup files to choose from, but there was only the one mentioned above. Is there any other way to access pre-update bookmark backup files? Thank you -

Mac 10.12.6 Firefox 59.0.2

Periodically some of my bookmarks are missing. I am able to use my profile file from a back-up to get them back.

How do I find out the reason and solve this problem
