Firefox Support Forum

Hi,

I find the new(?) "Firefox View" quite helpful but...:

I have two firefox desktop installs and one on my phone. My foxes are all set up to open with the tabs from the last session.

Expected behaviour: "Tabs from other devices" shows all recent tabs from all 3 devices (minus the current one of course).

Actual behaviour:

• On the desktop firefoxes, under "Tabs from other devices" I only see the FF-instance from my phone. Missing the other desktop install (see attached screenshot).
• On the phone, I only see the most recent desktop instance.

It seems like as if it either can handle only one mobile and one desktop install or it hides devices not currently active?

Thanks for clarifying and/or fixing ;-) Sören

All of my search history, passwords, bookmarks, everything is gone. I searched %appdata% and found my two old folders (one ends in .default other in .user). I went to profiles and changed them to default and nothing changed. It just puts me in default homepage and asks me to make a new profile. Please help, there is extremely important stuff that I've just lost for no reason.

I had formatted my PC due to error and while re-login to my firefox account, I have lost all sync , can you please check this matter at the earliest, really facing difficulty in remembering id's and passwords

There are 2 processes involved in Firefox Sync, and 0 differentiation between them in the language used to describe what Firefox Sync does in any of the documentation, this makes nearly every discussion on the topic highly confusing to borderline misleading.

When you press Sync, you are pushing settings to Firefox servers. When you sign in to Sync, you are pulling settings from Firefox servers.

Both of these steps are referred to interchangeably as "syncing" and there is next to no documentation of what causes each to occur nor what they actually do.

Why is this dangerous you might ask? Well, let's say I buy a new computer, I want to set it up the same way I use all my devices, so I sign in to sync to synchronize my settings, makes perfect sense. Nothing tells me anything is happening when I sign in, so I click the sync button because I want to synchronize my settings with my other devices. Big mistake. I've just overwritten the server-side sync profile with a default Firefox profile. You know how you fix that? You sign in and press the sync button to overwrite the sync profile again. But you know what happens when you sign in? You become synced with the now blank sync profile and lose all the settings that you want to be pushing to the sync profile. This just happened to me. Thankfully I was only choosing to sync add-ons and options AT THE TIME and I have backups that are about 6 months old and I rarely change settings, but some things like my homepage URLs are something that I do change fairly often, and I'm sure some additional sites were whitelisted since by default I just reject all cookies. I also thankfully use policies.json to block updates so I didn't immediately get assaulted by that too.

SO! I HIGHLY suggest that when merely signing in to Sync, the default should be for syncing to be off to start off with, so that you can choose what to "sync" BEFORE it occurs. However, because of the language, the question arises, what am I choosing to sync for? Am I choosing what to PULL from servers? Or am I choosing what gets PUSHED to the servers? When syncing is turned on, does that mean I an pulling the settings that I have chosen? Or am I am pulling ALL settings while only pushing what I have chosen IF I click the Sync button? Or do I push EVERYTHING?

It's incredibly unclear how the Sync feature works and both of the "main" articles on it are completely useless for understanding it because the term "sync" is used interchangeably for pushing or pulling settings.

What are the correct steps to rectify this horrid situation? Sign-in, set-up sync, choose "Options" and "Add-Ons" again, THEN copy over the backup settings, THEN Sync them to the "cloud"? If I have 2 different devices setup with sync, and 1 chooses to sync options and the other chooses to sync bookmarks, then I click sync on BOTH devices repeatedly, what occurs?

Firefox has always maintained that current tabs will be restored after a reboot of the browser, and indeed that was the case for the first half-dozen years I've been a subscriber. That has not been the case for the past 4 - 6 months however. I have the correct Settings for this, so it is not on my end. Why do I always get a fresh Firefox browser whenever I update the version (which is quite regular lately . . . maybe a new version of Firefox every 3 weeks). Please help.

In the past, logging in to my Firefox account has caused new installs to just sync with my previous settings, bookmarks etc, but my computer had a... spaz & I had to do a new install of Windows 10, and Firefox will not sync. I've tried hitting 'sync now'...

Yesterday my son had issue with FFox and uninstalled and re-installed. Upon doing this all my other firefox instances lost their pinned sites on the home page.

is there a way to configure a firefox instance as the bastion of truth, so that all other instances sync to it? and it asks before it makes changes?

Or even better after a sync have a list of what changed, and perhaps an undo.

I am attempting to sign into Sync on my tablet and am not able to receive the triggered Verification emails (neither the initial one when attempting to sign in nor any follow up ones). Oddly enough, it's only this device where the issue is present. I was able to use my desktop computer to successfully unlock my account after accidentally locking it and change my primary email address in case that was the issue. Both of these actions triggered email notifications. Even when attempting to sign into my tablet's Sync with my new primary email address I am not able to receive the Verification emails.

I have also double checked my spam folder and whitelisted accounts@firefox.com. I have not noticed any other issues with my tablet besides this very specific thing.

Would someone be able to provide guidance? I wasn't able to find any help articles about this particular scenario and am not sure how to proceed.

Thank you, B

Hello. I'm using Firefox 119 for MAC OS. However my device is labeled as Windows 10 Firefox. I don't have any Windows software labeled anywhere. I have signed out, restarted device and still no change. When I log into a website from Firefox, my "authorized device" is recognized as Windows Firefox.

Please advise, Thank you

my passwords and logins are not showing..!! even my bookmarks are not showing on firefox after i logged in using my firefox account. please help me resolve this its very important Sir/Ma'am.

Hello all, I have three devices, two laptops, and android phone. I have all three synced and running that way no problem other than one thing I have had an open question for since oct 2nd about mass opening synced tabs into active tabs...

Question here is, is there an active sync? like, I want it when I open a new tab on my android, it automatically opens same tab on both laptops, or i open something on a laptop, and the other laptop and android open it as well. same for closing and all that

Im not looking for it to auto complete forms or anything like that, just keep the same tabs opened across all devices

Very sorry. I saw 2 icons on my desktop and deleted one without checking to see if my Bookmarks were in both of them. They weren't. Do you know of any way to retrieve what I deleted, or should I just put them back as I need them? Also, I set up my original Mozilla account 5 years ago, and don't remember how to add a bookmark panel on the left of the screen.

I'm very sorry if it comes off as hostile. It's actually kind of out of fear that one day it will all break down.

As person on autistic spectrum I really need ability to maintain pleasant-to-eyes user layout. Even before the Quantum updates Firefox moved from pretty much perfect-looking browser to worse and worse (kinda Chrome-looking) one. That's why UserCss was a godsend.

http://prntscr.com/26cyw7p

But every few updates stuff breaks and I have to download yet another updated version of custom CSS, and often at least one option I am using actively is no longer available because firefox update broke it for good. Today was such day - after Firefox updated, suddenly tabs were way too high, extending into favorites tabs. After updating and reconfiguring (since config files are different with each iteration), four more customization options gone in between last and current CSS update.

I understand going forward and such, but if the visuals peaked in 2007, why not keep all the CSS working properly when doing so? Just do not remove old calls and such?

Long time Firefox/Mozilla user. Installed/upgraded/migrated on Win, Android, Linux (various distros) over the years.

This was posted under migration but might be relevant in this topic.

Built a new Win 10 system 11/21. Installed Firefox, logged in and Enabled Sync. Installed licensed Adobe photo editing software. No problems. Used for 2 weeks.

Spent 5 months in hospital.

Back home, used new PC for ~45 days; Win 10 went wiggy on me after an update - could not get to Settings menu ya da ya da. It went downhill from there. No identifiable hardware issues (tested memory and (.m2) boot drive, etc

Tried many fixes to Windows while trying to keep user data. Ended up reinstalling Win 10 (multiple times...). System working, but no bookmarks/passwords. Installed Firefox. Of course, it didn't work - understandibly.

Went to old PC, Firefox does not seem to give me the option to *see* my login password); looked up Firefox password (I hated to do it, but with ~500 userid/passwords, I started to let FF manage these a few years back). Found it. Went to new box and logged in. Password error. Digging deeper, it *appears* that the present password was set circa 2015 and the Firefox saved password was set circa 2021.

I've now been fussing with this a week. Searching, searching; trying pretty much everything I can think of. Nothing works.

Any path forward besides changing passwords on all of the involved (~20+) devices?

Now I need to try to recall where I put the recovery key ... (yes, I have since embarked on an extensive backup/restore point campaign which includes backing up backup system software).

Hi, The last update I got turned my browser background black. I tried to download the previous version. When I did I could not log on to my Firefox account. When I did logon the account was blank. I have a loptop that was previously synced. Can I sync from my laptop to my firefox account?

I have confirmed logging onto Firefox Sync does indeed break Netflix for me. I just was not so sure until now...

Details: I've gone a couple weeks without syncing and had no issues with any websites; watched lots of Netflix too.

After today's upgrade to FF97, I decided to risk it and log back onto Sync. Right away Netflix was broken in its tab, with "Pardon the Interruption. This title is not available to be watched instantly. Please try another title. -1044" and then "Error Code F7121 - 1331"

I have received this error code and more other similar ones from Netflix back a few weeks ago when I was actively troubleshooting this glitch. None of the fixes worked, and the ones that involved sifting through many dozens of about:config settings were avoided.

Thing is, back then, I made no changes I can surely recall, except upgrading to FF 96. OK, maybe some others...

And what's happening to my Netflix tab is not happening to any other tabs/sites, now or before; just Netflix.

I'm hoping someone here has seen this same thing happen and can shed some light on why my FF synced login breaks Netflix but when I'm not logged in, Netflix is ok.

Thanks;

I have a problem with the Firefox sync browser You have downloaded a fresh copy of Windows and registered the account again on Firefox in order to sync previous data. No previous data was fetched. What is the solution to that? How do I access a previous sync on the Firefox website?

Please reply with help, thanks respectfully
