Hi,

I'd like to ask if there are plans in the near future to support FIDO2/WebAuthn authentication for Firefox Accounts.

My question is motivated by the fact that right now there's no way to add a secondary MFA option as backup, and the industry-standard backup codes are very clunky to store safely and use in general.

Losing access to the MFA for an account which hosts all data (and essentially the day to day optimizations of workflows - saved data, bookmarks, etc.) and starting from scratch is a terrifying prospect (I've gone through it before), especially given that Firefox Accounts right now does not have any recovery options after that point.

It would be beneficial if one would be able to add, for instance, a pair of FIDO2 keys for this purpose, or even more broadly speaking any other WebAuthn providers (like Windows Hello). Those would not only provide a better security standard, but also better failover options.

I'm sorry if this is not the right place, but I've not found a dedicated forum for Firefox Accounts issues specifically - please direct me there if there's one.

Best regards, Artur Ciesielski

I purchased and installed Avast One for protection of my laptop. Since doing so, I have frequently found I cannot access certain websites. Examples of a couple websites: Lowes, Ticketmaster, Craigslist are a few I cannot access. If I use Google Chrome, I can access the websites. Firefox is my default browser and I do not want to use separate browsers when I cannot access websites on Firefox. Prior to installing Avast, I never had an issue accessing websites. Is there a conflict with Avast and Firefox? Prior to installing Avast One, I had used the free Avast malware protection and had no issues.

I'm using version 117.0.1 (64-bit) just installed Firefox Notes and now that is the only sidebar that appears, my bookmarked favourites sidebar has disappeared. All the help says go to 'View' check the sidebar for favourites if checked always on, fine but where is 'View' I have been through every dropdown i can find and there is no 'View'

Firefox Notes looks useful but not at the expense of losing my favourites sidebar.

Help please.

I accidentally saved a login with the user name blank and the password filled in. of course it does not appear on my saved password list. When I go the website and try to enter my user name on file with the password, Firefox rejects it.

How do I either delete the saved login or edit it to include the correct user name?

I run a small online photographic gallery. There is a problem when using a Firefox browser all other browsers display the page correctly. At the bottom of the thumbnails there is a date which is added when the photo is submitted to the gallery. With the Firefox the date is displayed incorrectly. (See attached photo). Any idea why Firefox is not displaying dates correctly?

Hi All,

I recently made a post that was resolved where enabling "Remember search and form history" would hang my browser.

In regards to this option, I really want to keep the "remember search" function but disable the "form history" option.

I'm aware that in about:config, the option browser.formfill.enable removed the form but is there a separate option to enable remember search?

Thank you

I had a hard drive fail and needed to do an entire new install. One of the very first things I do is install firefox and sync so I have all my sites tabs and passwords.

I did this and got the Secure connection failed errors instantly thereafter. no reboot nothing fixed it. Bing chrome opera all fail to work. refusing all secure connections. It will load microsoft but I cannot log in. It will load 1000 other sites as long as they are not the SSL pages. No other browser will load either.

This is instantly after signing in to sync.

I was left with no choice but to assume something got corrupted and wipe and redo windows AGAIN on this new drive.

This time I downloaded everything with bing and edge. Then when I was done after two days. I downloaded FF and tested it.

Worked great.

Signed into sync and BAM, all browsers and all websites refuse connections.

I have signed out of sync. I have deleted firefox. I have cleared SSL and DNS and every other setting I can think of or that chat gpt suggested. from cmd line. hard.

No remaining browsers will load. New firefox with no profile and no sync will load.

Whatever sync DID remains totally systemic and persistent and ONLY a total wipe of the drive fixed it last time.

Why will FF simply DO something like this and WTF did it do?

We are distributor of Firefox extension for dragon professional. ( We are self distrubutor of the the firefox extension )

It’s ID is dgnria_pro.firefox@nuance.com

Now we have done some modification to the same extension, while publishing it shows error as “Duplicate add-on ID found.”

Earlier we have used same ID for the Firefox extension in the year 2018.

Currently we have opened new account with same ID “dgnria_pro.firefox@nuance.com” and faced the mentioned issue.

We are expected to publish our extension with the same extension id as we don’t want our existing customers get affected.

Is there any way with which extension id “dgnria_pro.firefox@nuance.com” can be deleted from backend , so that we can reuse it.

We need solution for this ASAP. Please hlep us on this.

I tried to connect to a website and I received the message in the subject. I have been connecting to that web site for months on Firefox with no trouble. I connected without problems using Firefox just yesterday. After the Firefox problem, I connected without problems to the same web address using Microsoft Edge. I don't understand why Firefox suddenly has this problem.

Firefox cannot access my bank account. Bank says hello to my name when I log in, but then keeps saying "loading" and can never show me what is in my bank accounts. Why?

When opening Firefox, I downloaded a random file called 9Xjh-hy_.htm. the file weighs 0B and is empty when opened. I don't know what this file is and whether it is a virus or not.

Suddenly when I click on 'Preview' to an email PDF attachment it will no longer show the PDF file, but instead says 'We are having trouble previewing this file' ~ see screenshot. My only option is to download the file, and then open it. This is happening with both incoming and outgoing email PDF attachments. Any suggestions??

Ubuntu 22... Firefox was frozen, i closed it. couldnt open it again. Restarted pc.. kys.db last edited by firefox 1 week ago. I lost all my passwords, bookmarks, places... Files are changed 1 week ago.. No copies on mozilla folder... No fucking nothins... There is no copy of them, i changed it 3 days ago and Fx crashed...

Some companies gonna ask me for my personal id, finger print and photos.... Are you fucking serios? Where are my passwords?

I need them, now!

I am developing a website (using AstroJS, but i don't think that's the problem) and since yesterday I am experiencing issues when opening devtools. Once I open devtools the whole FF tab becomes unresponsive, I cannot even refresh the page until they are done loading. I can change devtool tabs from 'inspector' to 'console' to 'network' etc but especially 'network' and 'debug' tabs are blank.

I run a 'performance' capture and got these results. In the test I have only opened the devtools and switched to the inspector tab which is unresponsive. The CPU usage is at around 90% however, I don't really know how to read the finding and understand what the problem is.

So anyone that can help me understand what is going on here?

I just got a new laptop and downloaded Firefox for it. But I am getting pop up ads which say they're coming FROM Mozilla Firefox. I have to click them away, as small pop ups in the bottom right corner of the screen. They're typical of any spam. But some also create their own tabs!
