I've been using Firefox Nightly for Android and Firefox for Android for years without issue. I've left Nightly at build 68.5a1 as it has several features that later bulds removed. I sync across all my mobile devices but NOT with my desktop. When a website requires a newer browser version to run, then I switch to plain Firefox.

Today Nightly would NOT open. It opened and pointed to an offline file. I noticed it was marked by "///". I'm sorry I didn't take a screenshot or note the file.

Reading several posts, I removed Nightly, purged the cash and purged the data. Then I reinstalled Nightly from the apk file I saved. While the install went without a hitch, it will NOT permit me to sign in to synch the data saved in all my other devices. It just spins as this image shows.

I read a post indicating a direct url for sign in and tried it. But it only worked for Firefox and NOT Nightly.

How do I resolve this?

I want to sync my new laptop to Firefox on my Android mobile. I am asked to:

1. Open Firefox on your mobile device. 2. Go to the menu ( on iOS or on Android) and tap Synchronise and save data 3. Tap Ready to Scan and hold your phone over this code

But this command #3 is simply is not there in the Android FF settings. I see only Synchronise Now/ Device Name / Sign Out, plus Choose What to Synchronise. Nothing else. Any ideas?

Hello! I've been using Firefox since forever but never thought about using the sync feature until now. On laptop, when I press "sync now", a little spinning wheel appears for some seconds, then disappears. I take this means it has synced. On my android phone (Android 10 - phone's a Xiaomi Mi A2 Lite), however, I seem to have encountered a bug. I connected the two devices together using the QR code and following the instructions, and in fact the phone appears in the connected devices on the laptop version of Firefox. However, when I open Firefox on Android and go to my Account Settings, under "Synchronise now" it says "Last synchronised: never", and tapping it prompts absolutely nothing. No animation, no popup, no phone lagging, no sign it has received any command. If I try going in the synced tabs section (near the private tabs one), there is a big Sync button on the bottom right - pressing it causes it to say "Synchronising..." for about 5 minutes or more, but once it's done, nothing happens, and it keeps saying last sync was never. If possible I'd like not to re-install the app as I have a lot of tabs that I don't want to currently lose.

I always use Firefox mobile and Firefox Sync is always enabled.

My phone is dying and I need to rescue my Firefox browsing session : It contains thousands of tabs and collections of even more tabs (it built up because I never found a way to transfer these reliably).

A tab has a history, so back and forward pages, I need the full history of the tabs! Firefox Sync doesn't transfer these!

Firefox sync transferred 2300 tabs, but it seems that this set is incomplete as there is a large chunk of tabs missing, it's probably a thousand more. I restored these on Firefox desktop in a normal PC Firefox profile, they don't contain tab history as far as I can tell.

I also used collections in an attempt to synchronise better, there's over 800 tabs in there, I don't see these in Firefox Sync either.

Can Firefox Sync be archived/exported? I might not be able to replace the phone before my sync data disappears!

Please help me get to my data !

I recently bought a new phone. I have a total of three. The first two are semi-retired. They have aging operating systems and are no longer updatable. But I use them as wireless extension devices. About two hours ago, I installed and attempted to access Firefox search engine. I didn't remember the password. So I created a new one. That was successful. But then I had to enter a verification code. I did so and now there is a significant delay. This is in my new phone. Operating on Android 13. I'm accessing Firefox on one of my retired phones which are linked via WiFi to my new phone.

So, WHAT'S THE PROBLEM?????

I have a total of three devices, all with Firefox. Only one device has a sim card that is registered and subscribed.

I cannot get Firefox to sync my bookmarks to to my new android. Other things are syncing so I know sync is working it just will not sync the bookmarks. I have tried everything. I have checked my sync settings a dozen times. I've signed out and signed back in on both devices. I have even uninstalled on both devices while signed out and reinstalled and still I cannot get the bookmarks on my phone. Please help! It's a Galaxy s21 and I am on windows 10

So I just redid my phone today just to get a new fresh start again and before I redid it, my phone and Firefox were synced with my account. I had over 99 tabs saved....I have none that I can seem to find now....

The option to "sync and save your data" no longer appears in the main menu, nor under settings. Oddly, I can still send tabs from my laptop to my phone, just not the other way around. The option to "connect another device" in the share menu uselessly tells me "to send a tab, sign in to Firefox on at least one other device," when I've already done so.

In short, this doesn't appear to work anymore: [to set up Firefox Sync in Firefox for Android]

Hi there, I recently downgraded Firefox on my Android (5.1.1), as the new versions of the app became to get heavy.

I have logged in with my Account and am now trying to get the bookmarks synced. I have no Desktop right now to pair. The bookmarks and the Account are only available on my iPad, where FF is logged in and has the bookmarks synced.

Any ideas how I can fix this? Thanks for any help and regards, Dan

I'm trying to sync my bookmarks from Firefox mobile (Android) to my laptop (Dell) for the first time but there's no "Sync and save data" option under the dot menu on my phone nor is there any equivalent that I can find. How do I proceed?

I am trying to move all the synced tabs brought in from android chrome and Firefox pc into the current active tabs I have on Firefox android.

I've only been able to get 1 at a time to move over, but I have well over a hundred open in putting the two other browsers together..

Everything I've been able to look up about it only deals either the syncing part.

And, is there a way to have am active sync? As in, I open a tab in Firefox on laptop, it opens that tab on my Firefox mobile? And vice versa.

I checked community and tried every single suggestion like; I did disconnect all devices and reconnected desktop version first and then synced with my iOS one, didn't work for me.
