Firefox Support Forum

Hello,

I have 3 different profiles and I'd like to have a visual indication of the currently active profile. I've found that using themes is the best option (a red theme for production, green for test, grey for default) but I can't prevent Firefox Sync to sync the active theme between my profiles.

I have set both services.sync.prefs.sync.extensions.activeThemeID and services.sync.prefs.sync.lightweightThemes to false and restarted all my Firefox profiles.

After a while, all windows/profiles are synced to the same theme.

Are those settings really read by Firefox Sync ? I'm on Windows 10, Firefox 91.10.0esr (32-bit)

Thanks in advance for your help !

Hi! I have 2 apple computers running high sierra with updated versions of Firefox. The "laptop" has all my current work on it in Firefox using 7 browser windows with 60 tabs open. How do I get all that to open on the other computer "desktop?" On the desktop, the Firefox "synced tabs" sidebar is open and showing all the laptop open tabs...

I am logged into the same Firefox account on both computers which have different names in my Firefox account.

THAAANKS!!!

I switched from Chrome to Firefox recently, but am unable to sign in to my Firefox Account (whilst using Firefox). I'm on 88.0 (64-bit) on the latest public release of macOS.

Whether I try to sign into Firefox Sync using Firfox's menu or Preferences screen, or try to load accounts.firefox.com — just nothing happens: in the browser, the Sign In button doesn't do anything, and trying to load the URL I just get a blank screen. If I go to https://support.mozilla.org/en-US/fxa/authenticate, and click the 'Continue with Firefox Accounts' button, again - nothing happens.

I've rebooted my machine, disabled my VPN, and disabled any add-ons which might conflict. I'm posting this question having signed in via Safari, so I know my account works and my network connection is okay.

I couldn't find any Help articles. Does anyone have some suggestions I could try please

is there a way so i can transfer the sync data to a different profile or change my current account password so i wont lose my sync data? inside my current firefox account i have tons of data i would rather not lost so please tell me a way to keep all my data

Hi guys, Yesterday when I found that Firefox was updated and reinstall a new version by itself and the problem is that it deleted all old data (passwords, cookies, preferences...) and I did not find the folder "old firefox data" on my desktop. Is there a way to get back all those data please?

Many Thanks

Hi team! I´ve been using my private account also as an office account for my work laptop for over 1.5 years now. Now I wanted to split these things and create a second account via following routine:

primary account was mp.*§$%@gmail.com I added my office email as secondary email: mwo*"§$@company.com I changed secondary to primary email and deleted the mp.*§$%@gmail.com from the account

Now i wanted to create a new account with mp.*§$%@gmail.com for my private things but I only get the login screen to type in my password, so there is no chance to create a new one with my private email.

Could you please give me any hints on this?

Thanks in advance!

PS: yesy the private email with smth like "+firefox" would work, but I want to keep things clean and memorable.

Hello.

I have been using firefox for a quite while now, I have LOTS of critical data linked to my firefox account (all the passwords, important bookmarks for work, etc)

I completely formatted and reinstalled windows on my pc because it had software issues that made it impossible for me to use my pc, after that I installed firefox , but forgot password for my firefox account, so I reset it with my mail, but now I can not sync to my very important older data that I desperately need.

Is there any way I can recover my data? Please, it is very important for me.

you can check that all the activities happened from same IP address, and that I searched for "windows 7 iso file" using duckduckgo right before I requested password reset

thank you in advance.

I normally use Firefox desktop on my Linux computer.

Last week, I started using it on a public computer running Windows. I installed Firefox Portable and then logged/synced into my Firefox account on this Win computer. I noticed that in the Firefox Portable Windows “about:preferences” page, it says “Your browser is being managed by your organization”, which links to about:policies. In that “about:policies” page, it shows this https://i.imgur.com/JmD8nXg.png Policy Name: DisableAppUpdate Policy Value: true. Now I’m back on my Linux desktop computer and it also has this “managed by your organization” message in “about:preferences” and the same “about:policies” stuff. In other words, it appears that this policy was copied from the Windows public computer to my personal Linux computer. I don’t want that.

How can I undo this? And how can I block this sort of policy syncing?

Netflix no longer works on Firefox. After chatting with their help, I tried it on Google Chrome and it works just fine there. But I want to use Firefox. Can you help.

I have tried this several times over a few years, and have never got it to work I know it must be something I am doing wrong because if it was a glitch or bug, it would have been fixed by now. Usually I need to do this if I need to reinstall the OS, (Windows and Linux), or a new pc, the usual, but this time I had a major crash, so I'm starting over.

Anyway I have signed in on my pc to my FF account, and went through the menu to turn on sync, and I get to the page where is says, "when ready click next to display the QR code". I get my android out, open FF, sign in, click the "Scan" button, the FF scanner opens,, I open the QR code on the pc, (I have also went to the website to get a QR code). Then either way I scan the code, and get an errror msg "Must scan from inside FF". I am scanning from inside FF, with the FF QR scanner.

I don't uinderstand how of the 20 or more times I have tried to do this, I can't get it to work. I don't understand how I screw up every times, over a few years. But I also know as I said, if it was a bug MOzilla would have fixed it by now. Usually I give up on that and just log into both the pc and the phone, close both browsers and reopen them and it will go ahead and sync.

But not this time, I am unable to get it to sync for anything. I've been working on this for 3 days now, and at this point I'm confused, I don't remember what I have and have not done. Let me add, and I don't know if this will make a difference, I don't think so, but what do I know? Originally this all started, when I had to reset my password. I tried for 4 days there to get a recovery code to work. (The following is just to describe what I've done, and is not a second question) I had one downloaded, and saved on my pc. But no matter what route I took to go through the reset process, exactly as described in the help file, I never could get a place to enter the code. I read every article I could about it, and finally it seemed easier to just reset the password and resync than try to get the code to work.

Which is why I am sitting here, desperatly needing to sync my data, but unable to. If anyone can tell me what I need to do I will appreciate it. If you need any more information, just let me know.

Hello, I was reinstalling my OS, and I didn't create recovery code for my data to retrieve it after (which I found out after reinstalling my OS) on my Mozilla Firefox account, I had a lot of passwords, bookmarks and data that I need to recover, also for my full time job a lot of valuable data which I have lost now. I couldn't find any email address so I can address my concern directly, It's why I am posting here. Please help, I am so lost now. I can also provide you with any information needed, just let me know.

Firefox Account Email: [email]@hotmail.com Contact Email: [email]@hotmail.com

I would really appreciate your help, and hoping on resolving my concern in a timely manner.

Following direction on Help Page - Trying to sync tabs, bookmarks etc from one laptop to another. In settings, devices are said to be logged in and sync set to sync pretty much everything. Clicking the menu top right - only shows my email @ the top, then New Tab etc - but nothing about "Sync Now" or "Sign In" What am I missing? TIA, Jean

I know there's [[an article|https://support.mozilla.org/en-US/kb/sync-custom-preferences#w_sync-custom-preferences]] on how to sync custom preferences. I wanted to sync my toolbar customizations and some other preferences like disabling disk caching. And I don't even have other firefox instances, instead I just want to sync only on one device, so that I can continue the same setup when I signin later on the same device.

I've tried to add services.sync.prefs.sync.browser.uiCustomization.state, "services.sync.prefs.sync.browser.cache.disk.enable" and set it to true. But it doesn't work. What am I missing? No one seems to address this. May I am missing something.

I have a question regarding syncing. Is there a way to remotely remove all synced information from Firefox on a particular PC without actually accessing it? For example, if I sync my home PC Firefox with my laptop or my work PC. Then, one day, for some reason I no longer have access to my work PC, and all of my sensitive information is there. Or if I lose my laptop, or if it is stolen... Is it possible to remove all sensitive information from a remote synced PC? Alternatively, is there a way to remove all synced information every time I close the browser? This way I can remove a particular PC in my Firefox account and once the browser is restarted at the remote location, the data will no longer be pulled and synced. Can this be done? Thanks in advance!

When using "send tab to device", the submenu previously showed all synced devices, in my case, more than 10 devices. Recently it only shows 4 devices and there is no way to access the other ones. Is this broken or is it a recent change? If so, can I revert the behavior with a preference?

Under "manage devices", I still see all of my synced devices, they just don't show up in the "send to device" submenu.

Hello, Is there a way to use a different theme on one machine (light) and use the dark theme on a different computer but still be able to sync the data?

I have tried this from a previous question https://support.mozilla.org/en-US/questions/1242818

Set services.sync.prefs.sync.lightweightThemes to False, but this does not work.

Did it on both macOS machines, closed and restarted the browser, and changing the theme on one browser ends up changing the theme on the other machine.

Is there any way to have to separate themes on two different machines?

Thank you!

I am trying to add a secondary email address to my firefox/sync account but there is not button to add a new address. Help articles state that there IS a button, but I don't have one. Thanks.

I have a laptop that I used from 2012 to 2015, and sometimes I start it up in order to check my Firefox history and find some URL that I visited once. Today when I tried that, I couldn't get the history. Ctrl+Shift+H didn't work, and when I hit the History menu, the option "Show All History" was gray. What should I do?

I opened the profile folder and saw that there's a big file called places.sqlite, which I think is the history file.

I did set up Sync once, though it didn't seem to do anything -- the history was still what it was when i stopped using that laptop. But I notice today that if I start to type in the address bar a URL that I have used recently on my present laptop, then it suggests the whole URL. In other words, it knows what I've been doing recently on my present laptop.

I accidentally deleted a huge chunk of my history with "delete page/forget about this site", fat fingers! Is it possible to recover this history using sync?

thanks
