I have several saved cards in 152.0.1 (64-bit). When on a payment site the drop-down list shows up as expected, so the extensions.formautofill.creditCards.supportedCountries is correct and working (GB). Also address filling still works, as does saved passwords,

However if I try to "Manage payment methods" the resulting list in "about:preferences#managePayments" is blank. (see image)

I have tried toggling on and off "save & autofill" and restarting, but nothing helps.

Adding a new card works, and the new card appears in the drop-down list on a payment form, but still nothing appears to edit or remove in the settings. How an I edit this list?

PS: I have disabled ALL extensions.

The summary says it all. Some time in the pas few days, my saved payment methods disappeared. If I try to use Add new payment method, enter my information and then save, the same things happens. It just disappears as if I hadn't done anything. Any suggestions on why it's suddenly refusing to remember my payment info?

When there is a field to fill in my credit card info, the info will appear and let me select the CC I want to use but when I move away from the field the CC info goes away.

I have credit card auto-filling enabled and several credit cards active. However, most of the time, when I go to use the autofill, though the card choices appear and I am able to select one, and it usually temporarily shows the fields to be filled, when the menu closes, the auto-fills are gone! It's worse than not having autofill at all. This seems to happen the majority of sites where I try to use it.

Issues with redirect. A group I am a member of uses Constant Contact. An email is sent with a link to a report. Receive this error:

Firefox can’t connect to the server at deuaxb4ab.cc.rs6.net. What can you do about it?

This worked last week.

Firefox 152.0.4. Win10

I'm trying to find a solution for having all tabs open across devices. Currently, my desktop has about 50 open tabs that I access regularly. Today, I installed Firefox on my laptop, signed in and initiated syncing. All bookmarks came over, everything looks great, except that none of my open tabs from the desktop browser show on my laptop.

I would like to have identical tabs open across devices. Is there a way to configure this where a new computer being logged in automatically receives all open tabs from the initial device and then tabs automatically sync based on whatever is opened/closed on either device after the initial tabs are identically synced?

I rely on Firefox entirely for my business. I'm really concerned that Firefox is become choked up - it is really slow to load pages. Am desperate to get it cleaned up ('serviced' so to speak) but am finding it difficult to get simple instructions to do this myself. Where can I get expert help?

When I use my bank's desktop website, I can use all services on the site except when I request a Proof of Payment. I can do it using Edge. How to fix in Firefox?

I have also entered the bank's websites (http version and https version) on the allowed websites section in Firefox settings. What else must I turn on or off?

Subject: Firefox Sync appears to have erased all bookmarks after setting up a new Windows installation

Hello Mozilla Support,

I believe I have encountered a Firefox Sync issue that resulted in the loss of my entire bookmarks collection.

Here is exactly what happened:

I have been using Firefox Sync for several years without any issues. This was not my first Windows reinstallation. I have restored Firefox through Sync multiple times before. Firefox Sync had always synchronized bookmarks, passwords, history, extensions and open tabs correctly across my Windows PC and Android phone. I had approximately 350 bookmarks, organized into folders. Timeline Yesterday I performed a clean installation of Windows 11. I installed Firefox 152.0.5 (64-bit). I signed into my existing Firefox Account. I did not immediately enable Sync, so nothing was synchronized at that point. Today I enabled Sync and waited for the synchronization to complete. Passwords synchronized successfully. Browsing history synchronized successfully (it took a little longer). Extensions were restored successfully. Bookmarks never appeared.

Immediately after noticing this, I checked Firefox on my Android phone.

At first, one of the bookmark folders still showed that it contained more than 300 items (I saw the item count), but when I opened the folder it was completely empty. After synchronization finished, all bookmarks disappeared from both devices.

Additional information Browsing history is still present. Saved passwords are still present. Extensions are still present. Open tabs synchronization continues to work. Bookmark synchronization is enabled. I am signed into the correct Firefox Account. The second local Firefox profile is empty. The automatic bookmark backup now contains only the current state (7 items), indicating that the original backup has already been overwritten. The current profile contains both places.sqlite and places.sqlite-wal. The only Sync error log is related to a temporary DNS lookup failure (NS_ERROR_UNKNOWN_HOST) and contains no bookmark synchronization errors.

Because history, passwords and extensions synchronized correctly, this does not appear to be an account or authentication problem.

What concerns me most is that I briefly saw the bookmark folder still reporting over 300 items on Android before it became empty. This makes me suspect that something went wrong during bookmark synchronization rather than the bookmarks simply never existing on the server.

Could you please advise:

Is there any server-side recovery or investigation that can be performed for Firefox Sync bookmark data? Are there any diagnostic logs that I can provide? Is this a known issue with Firefox Sync after connecting a newly installed device?

I would greatly appreciate any assistance, as this bookmark collection had been accumulated over many years.

I have a Sync error log available: error-sync-1783454370913.txt

It only contains a DNS error related to tabs synchronization: NS_ERROR_UNKNOWN_HOST

There are no bookmark-related errors in the log.

Thank you.

I attended a conference and can't open any of there links due to the fact it is on the cloudfare program???? website is https://s3.us-east-1.amazonaws.com/RETA/2026/files/index-table-2026-mid-year-update-.xlsx and the message

this is what I get back each time and I have never had this happen before:

Server Not Found

Firefox can’t connect to the server at s3.us-east-1.amazonaws.com. What can you do about it?

Try connecting on a different device. Check your modem or router. Disconnect and reconnect to Wi-Fi.

Hello I just filled out a pdf and the font or writing came out blue I want it in black is there some where in Firefox i can get it in black w font or writing please Advise thank you

I’m using the latest stable Firefox package from the official Mozilla repository for Ubuntu, on a system with 32GB of RAM.

I’m also using Microsoft Teams for work calls, in the browser (because Linux) and I notice that Ubuntu has killed the FF process twice last week because it was using too much memory - see attached image. I’ve only had 4 or 5 Teams calls last week so this isn’t a great success rate. It seems that after half an hour or so, FF has hogged so much memory that the OS feels the need to kill it.

If this is a known issue: are there any known workarounds?

If this is not a known issue :Can I help by providing troubleshooting data? How?

Thanks in advance!

Firefox updated its version on my iMac desktop two days ago and all my bookmarks are gone. There's a message at the top that says: "For quick access, place your bookmarks here on the bookmarks toolbar. Manage bookmarks..."

All my bookmarks are gone as if they were never there. I have a My Passport Backup hard-drive but I don't know where I can find them and restore them.

I get the following pop ups, the blue-green ones in images. When I click "CANCEL" I get the McAfee window shown. Can't find where the popups are coming from. I was able to get rid of on another computer by uninstalling Firefox, but lost stuff. I use ESet now and wouldn't go near McAfee again. Does anyone know how to get rid of this?

Beware of McAfee!!!! They act like crooks!!!

The built in VPN worked great for me for a couple of months, but now whenever I try to turn it on, it starts with the "Get Started" screen, which takes me to a page to confirm my account. When I press continue the VPN button just goes back to the "Get Started" screen & the loop repeats. I've tried signing out & refreshing my Firefox installation but I keep getting the same result. Before it started doing this the button to turn on the VPN was appearing but would not react to clicks.
