Firefox has begun opening very [very!] slowly, as well as crashing and freezing during use. This is happening on all of my three machines, two running Win 7 and one Win 8. I have tried refreshing and disabling hardware acceleration, but to no avail. Now it seems to freeze on opening and takes a minute or two even to become responsive, if at all. When I look at Task Manager during a freeze I see the Firefox process is using 35-50% of memory [i have 8GB, 12GB and 16GB] and up to 50% of processsor resources. All has been fine until the last couple of weeks. As an adjunct, in the last month I have noticed an almost permanent error message on the status bar - "Sync encountered an error while synchronising: Unknown error. Sync will automatically retry this action."

Everything was hunky dory until the awful v48 update. With no other changes to the system, bookmarks are now annoyingly slow to use. If I try to bookmark this page for example, FF has to think for 2-5 seconds before I can enter tags. After saving the bookmark it freezes for another 1-3 seconds before I can do anything else. This is an awful downgrade.

There were absolutely no other changes to my setup except for the update. I didn't change any preference, install an addon, or the like. In any case, I performed a safe mode test and this makes the pauses even worse.

What else can I try? Your FF knowledge would be greatly appreciated.

I'm using FF63.0.3 and a Mac with OS 10.11.6. Firefox works generically well EXCEPT sometimes when I try to save bookmarks, all hell breaks loose. I save them, they LOOK like they're saved, and I try to sync. The sync goes off in never-never land, and never finishes. Aaargh, I say, and I restart Firefox, whereby my new bookmarks are GONE! No memory of them. No record of being at them in my History. Now I should say that when I kill Firefox in this circumstance, I get an "Application not responding" error, so clearly something has already been hosed.

I should say that this happens occasionally. Not always. But it's pretty exasperating when it does, trying to recover those lost bookmarks. Normally, when I sync, it just takes a few seconds, and everything is keen.

Insights abut why, or how to prevent this? This has been going on for months, surviving re-downloading Firefox, and reboots.

I don't know why - possibly after a firefox update to 49.0.2? But Firefox on Windows 10 is no longer saving or using my saved passwords. When I try to display saved logins, there are none showing. However, I do have intact key3.db and logins.json files, and I can see in logins.json that there are lots of logins stored in there. So I'm sure the data are there, but just not being read.

Uninstalling and reinstalling didn't help. Refresh didn't help. Synch seems to connect, but doesn't help. Isn't there some command to force the browser to read the saved logins file?

Hello, I always have Sync turned on, on my Laptop (PC) and my iPhone. When I reinstalled Firefox, everything was synced except my bookmarks. I have all my bookmarks on my iPhone. How do I get my bookmarks back on my Laptop? Can I somehow export my bookmarks on my iPhone, which has Firefox mobile, and email them to myself on my Laptop? I would really appreciate it very much if anyone could assist me this this issue. Thank you.

In July, I first installed Sync on my PC (Windows 7), my smartphone and my tablet (both Android 4.2.2). It worked perfectly, with all bookmarks, history and tabs synchronized, and proved useful during holidays as I was only left with my Android devices.

I haven't been using Firefox much with my Android devices lately, but yesterday, when I checked their bookmarks, I realized they were out of sync with my PC's bookmarks.

I have been through all the tips offered on this site (unlinking, updating, re-linking...), with limited success : the history of the various devices in synchronized, but NOT the bookmarks.

I tried to create a new account with a new email address, but I am still waiting to receive the email for verification (although the email address works fine). Therefore I have deleted my 'old' account and re-created a new one, with the same email address.

Any clue as to how to synchronize the bookmarks?

I made a Firefox account a while ago. I use Firefox in my user account as well as when I work in the Admin account. I think I have noticed before that these two Firefoxes were automatically synchronized now and then. But since I had to deal with a problem in the Admin account (continuously opening download windows) and reset Firefox there, the Hans- the user- Firefox differs from the Admin Firefox. That does not matter much in itself, but what if ever I change computer or something? Which version will be leading then, and decide on what kind of Firefox will be installed?

Today for no reason all my saved passwords on my desktop Firefox browser have disappeared. Fortunately on my android phone they all still exist. I have tried to sync and on Android it confirms sync has happened but the passwords will still not show on the desktop browser. Only new passwords now entered are being recorded.

I have never had this problem ever and have done nothing today that would cause this to happen

I have the most recent FF 66 and up to date Windows 10

Any suggestions welcome please.

Hello, I am a bit of a tinkerer and a tech junkie. However, I still find sync to be a very useful and handy tool, and have it applied to all of my devices (tablets, phone, multiple computers). Due to my never-ending quest to make things better, though, I am frequently changing OS'es and uninstalling apps/rearranging registries on many of these devices, so I often find myself needing to reinstall firefox (and thus re-sync).

The only problem here is that sync recognizes each new iteration as its own separate device, even though a vast majority of them cease to exist entirely and are gone forever. This makes my "Tabs From Other Devices" page a huge pain to access, as most of the device names are the same and a lot still have active pages in them.

How would I go about deleting these old accounts from my sync account? Changing my password does no good at all, as since the devices cannot access the server any longer they are still present in my database, and as such are still annoying. Any help is appreciated!

Two pictures of the problem is as follows. As you can see, there are many apparent duplicate devices: http://imageshack.com/a/img14/5290/a29b.png http://imageshack.com/a/img59/6697/6sp4.png

Sync fails sync Bookmarks on one PC only.

I've recently noticed lots of error-sync logs in the %APPDATA%\Mozilla\Firefox\Profiles\<My Profile>\weave\logs folder. My sync is set up to handle Bookmarks and History only.

I have 4 devices, 2 PCs - both Firefox 56.0.2 32-bit and 2 Android devices (latest Firefox, not sure of version). All 4 were previously set to sync together, Bookmarks/History.

One of the PCs (Windows 7 x64) - has the logs, but I've read numerous articles online on how to fix Sync myself or correct a corrupted places.sqlite database as that's what the error log seems to be suggesting is wrong.

Running check integrity against places.sqlite gives me this:

> Task: checkIntegrity - Unable to check database integrity > Task: checkCoherence - The task queue was cleared by an error in another task. > Task: expire - The task queue was cleared by an error in another task. > Task: vacuum - The task queue was cleared by an error in another task. > Task: stats - The task queue was cleared by an error in another task. > Task: _refreshUI - The task queue was cleared by an error in another task.

I have tried to repeat the process in safe mode and with a clear (new) profile - the issue persists. I have deleted places.sqlite (after making a backup) to see if sync suddenly starts working - but the bookmark related issue simply returns.

I have signed out on all devices, changed my sync password and logged in on just the PCs (for now until the problem is resolved). I have deleted all bookmarks on the 'problem' PC, then re-imported them from Internet Explorer on the other PC, then reactivated sync - this seems to initially work but once the 'problem' PC has the bookmarks, it tries to sync them and the errors return.

The error in question appears to be this:

1527797240532 Sync.Engine.Bookmarks WARN Error while backing up bookmarks, but continuing with sync: Error: Error(s) encountered during statement execution: database disk image is malformed (resource://gre/modules/Sqlite.jsm:823:25) JS Stack trace: handleCompletion@Sqlite.jsm:823:25 1527797240534 Sync.BrowserIDManager DEBUG _ensureValidToken already has one 1527797240543 Sync.Engine.Bookmarks DEBUG Successfully wrote previousFailed.

I can supply the entire file if required or put it on pastebin.

The only real issue I'm having is that I simply want my history/bookmarks (but nothing else) shared between all my devices that use Firefox, be it quantum or 56.0.2.

I have not tried Firefox Quantum (as numerous add-ons I use are unsupported and I didn't want to simply switch without a road back). I did try Firefox 52.0.8 ESR but the first thing it did was delete my places.sqlite so I wasn't able to reproduce the problem I'm having as I don't want to lose my history data (bookmarks are stored primarily in IE for convenience and simply imported when I need them as I use 'PlainOldFavorites' extension).

This looks like a bug with firefox sync or a corrupt file, but since I've cleared places.sqlite and let FF recreate it, I'm at a loss. If you need any further information to help solve this, I'm happy to provide as much as possible.

Thanks for any suggestions you can offer :)

I have a PC (Windows 7) and I would like to back up my bookmarks, etc, as I'm switching to another PC, so I made sure I had the latest version of firefox and sync. I created a sync account and and got a message that the sync would begin momentarily but nothing has happened (this has been over 2 hours). I also tried the "sync now" option under tools. Is there a way to tell if it's even working since there is no status bar?

I've tried selecting all the items to be synced and disconnecting and reconnecting to firefox and still not working.

Thanks.

No problems before I signed up for an account to use Firefox Send. Immediately after that I started to get an annoying pop-up window asking for my master password immediately on browser start.

I want to be able to browse sites without entering a password, and I also want to continue using a master password but only for sites which require a log-in.

I deleted my Firefox account in the hopes that would fix the problem, but the pop-ups keep coming.

I tried unchecking "ask to save logins and passwords for websites" in preferences but that didn't work.

I have not deleted my saved log-ins and tried a new/clean browser because I spent a long time getting all my add-ons and log-ins set up and I don't want to have to reinstall everything, and I am concerned that if I save my profile that it will just re-install the problem.
