Firefox for Android Support Forum

I am trying to sync my desktop Firefox data to my Android phone, a Samsung Galaxy S21+. In every help topic I read, it says to click the three dots on Android, go to settings and click "Sync and save data," then click "Ready to scan" and scan the QR code provided from my desktop account. The issue I am running into is that the "Sync and save data" option does not exist on my Firefox Android app. If I click on my profile on the phone, I can click "Sync" but it doesn't do anything. It does not work if I try to scan the QR code through the phone camera instead. I am at a loss for how to sync my Mozilla account on these two devices. My Firefox app is up to date. If anyone can help me I would appreciate it.

Good morning. I recently changed smartphone, activating Firefox Sync between both devices, making sure that the old one didn't have the setting that makes open tabs inactive. Now after a week I don't see anymore synchronized tabs with the old smartphone. How can I solve it? Thanks, Phil.

I accidentally cleared the Firefox app's data while my account was still logged in and now all of my account data is completely gone. Am I just done for or is there a way to get this back?

I've had no issues with Firefox Sync on desktop but frequent issues on Android.

I've reported issues previously here: https://bugzilla.mozilla.org/show_bug.cgi?id=1879003

Yesterday, it failed in a different way, announcing that I needed to sign into Sync. I've tried a dozen times yesterday and today using both QR scan and email confirmation. All fail in various ways. For example:

• After scanning QR code: "500 Error Oh dear, something went wrong there"
• After scanning QR code: "Pairing not successful. Error while creating the pairing channel"
• After scanning QR code and approving on mobile device and desktop, desktop says success, but phone stays on "Approval now required from your other device" Interestingly this page isn't open in the normal browser. If I click the three dot menu, it says "POWERED BY FIREFOX, Open in Firefox"
• After going through all the steps and it saying "You're signed into Firefox," yet when I go to share a tab, it asked me to sign in.

Any tips on getting Firefox Sync to work? I don't see any troubleshooting sections in the online help articles.

Hello. I tried to log into account with two-factor authentication. after entering the code, the error "missing parameter: %(param)s" appears. Thanks for spending a time

I am using a Android device, I am finding sync issues in login to my browser, a computer screen is active on my device may be through wch a shared browser is connected. I am not sharing my connection with any one nor I have a computer system for my internet access. While signing in its showing a authorisation error. My internet connection is totally private and confidential & personal wch I am the only user. Why is that I am finding authorisation error and who is the one who authorises me...?? I don't have any authoriser for my acount or browser

I sync Firefox between my desktop and Android. After I set up the syncing, I updated the login credentials for all of the websites I visit. I did this through my desktop. When I check my saved passwords on my Android, it shows all of the updated credentials. However, it also shows credentials that I had deleted. I do not show the outdated credentials on my desktop.

I tried uninstalling Firefox on my Android, restarting the device, then reinstalling it, but the problem persists. I could go through the credentials one-by-one, but that's literally hundreds of credentials to sort through, which would take a long time.

Any idea what's wrong and how to fix it?

I logged into my account on my mobile browser, and was able to see all my passwords and saved data that I had on my computer. I ended up signing by accident and when I logged back in all my passwords and bookmarks where gone. How can I restore them??

I have Firefox on my Windows 11 desktop computer. As of today, I cannot see my Firefox on my Android smartphone. The problem started when I saw that my computer desktop Firefox would not automatically update. When I tried to update manually, I lost my ability to use my Android Firefox. Don't know what to do next.

My computer restated itself with an update. Now Firefox and all my bookmarks and saved log in info is gone. I normally can solve this by simply logging in and syncing from my phone. Firefox will not open a log in page from any of the icons on any Firefox page. I can log in using Chrome but of course sync from there is not possible. I can log in on my phone also. The problem is either my Mac settings or the Firefox settings on that computer. I have searched FAQ etc. No clear solutions can be found.
