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?

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 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

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.

Samsung Galaxy S9 plus.

I mistakenly uninstalled Firefox, then reboored and reinstalled it. How do I recover my saved passwords?

I tried going to the Data folder, but there is only 1 folder there, "export messages", for an app that lets me print out or save existing text messages .

Help!!

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

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]

Hello, I get the 500 Error screen when trying to sync Firefox on my phone. When trying both scan or email. ( I had to erase the app after having signed out, to try and fix a bug. The app kept freezing) Can't seem to find any help from Firefox's... elaborated support system. I'm probably dumb. But I don't have any more time for that. And I can't speak with anyone anywhere apparently.

Waiting for a potential answer here, or switching back to Safari in 24h.

Thank you !

Firefox on laptop says to seek and save data with food, open Firefox go to menu at shoes sick and save data but there is no option for this. How could I tell if I am synced and how to do it?

Hi,

I have a plenty of tabs accumulated in my FF on Android, v119.1.1 (Build #2015984795), 2a75e15258+ GV: 119.0.2-20231108221453 AS: 119.0.

Within Tabs menu there is Share all tabs option. When clicked, the Save as PDF, Print, and typical android sharing options are presented.

Click on Save as PDF does nothing. Sharing to other apps works partially (text list is shared, but some parts of it are not kinks but a concatenated text of tabs titles combined together, not clickable, not https:// part).

The phone has lots of tabs, many of which are deactivated.

I want to backup them and review on bigger screen, but can't do that :)

Sharing to other devices connected via Mozilla account shares only subset of tabs, not sure about the logic, the most recent ones for sure + some deactivated but not all of them.

I’m devastated. Please tell me how to recover all the tabs I lost.

I had disabled the sync feature weeks ago, but when I opened Firefox just now, it had 1) synced with my MacBook 2) lost every open tab on my iPhone

Please please someone respond to this. Why is there no solution offered in this forum? Clearly a number of people have had the same problem.

Thank you
