Firefox Support Forum

Hello, After the last update (September 2023), I've been having issues with in-game ads being blocked, even with exceptions added and Advanced Tracking options turned off.

I got them to work for a couple of days, but now they're being blocked again. I've cleared cache & cookies, restarted Firefox, reset permissions, all have not helped.

Please advise!

I'm using Windows 10 on an HP PC screenshot of website permissions included

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

Mozilla's issue, as the Chrome is working perfect.

You don't indicate what or where this certificate is coming from for any forum user to know what is happening or why it's not being recognized by the browser.

Hello,

I'm trying to change some of my old passwords and I want to use the 'generate password' feature in Firefox. However, this is only available on sign up pages and NOT within the about:logins page within Firefox. Is there a way where I could generate passwords from within the about:logins page? Or at least anywhere in Firefox that doesn't involve finding a sign up page to generate a password?

Thanks in advance!

I want to report that spyware named FindItPro which I, foolishly, downloaded. Well, it's a virus, right? But no antivirus can delete it completely. It comes back and you can't find the source. So, there should be some problem in your browser that allows it to live.

I'll send you a website where I got it. [link to suspected malware removed] BE CAREFUL. Virus will be downloaded along with Opera browser or something. I'll send this report also to some antivirus company. Yes, I was foolish, but I hope you will fix it.

I'm trying to set an exception to popup blocking. When I enter the URL of the website in question and click Allow, the URL ought to appear in the list of exceptions; instead nothing happens. This is a relatively new installation, and I haven't tried to enter an exception before; therefore the list is (and remains) empty.

I'm using Firefox 117.0.1 (64 bit) under Windows 11.

Hi there, i got different firefox issues displaying websites. my configuration: firefox 117.0 (64bit) cleaned 5 minutes ago addons deinstalled (all) kaspersky firewall deactivated fresh start on different sites an ad guard site pops up telling me protection for children when relaoding F5 site it tells certificate is not safe after reloading whit shift+f5 it tells site is not reachable

if i open the same website on chrome on the same laptop everything works fine. there are days when these errors do not occur. on other days it is simply impossible to surf the net. i do not have installed ad blockers or even adguard. but adguard website shows up. we got an avm fritzbox 7590ax to access fibre 500mbit. it seems firefox is not able to interact with something. maybe provider netcologne?

i treid everything to get these website going but nothing worked. and it is only firefox. chrome works. opera too. edge okay.... :-)

any suggestion where to start find out where this adguard websites comes from? any idea why firefox got so many security issues with just normal websites?

best regards wally

If I want to read a Pocket article, it asks me to sign in to Firefox. When I put in my user name, it does not advance beyond this page: https://accounts.firefox.com/oauth/signin?client_id= . . . I'm guessing that it may be allowing cookies, but it looks like cookies for Firefox and Mozilla are being allowed. Can you assist so I can save a Pocket story?

When filling out forms in Firefox, it offers to autofill everything - first, middle, and last name, home address, credit card info, just now it even showed it has my social security number. When I go into Settings/Privacy & Security/Forms and Autofill, and click to view Saved Addresses/Saved Credit Cards, there are no entries to edit or remove. Why does Firefox have this info saved, and how can I remove it?

Is spell-checking done locally on my computer, or is it done on the Mozilla website? I just found out that the Chrome and Edge browsers send my typed message to the home office, and that is where the spell-checking is done. Can I assume that this process is done locally on my own computer with Firefox?

I've been paranoid about security for many years, and every little bit of info I can add to my personal well-being lets me sleep that much better at night.

I am currently 82 years of age and have been using Firefox since it first became available, just because of its advertised security features. Quite happy with it and hope it stays on top of my needs.

And I have the same question regarding Thunderbird and its security properties.

Thank you.

I started getting screen flashes and then identifying pop up windows that go to adform dot com addresses, that are blocked on my computer so nothing other than a error shows up. Its annoying and random. I have checked security page and it says Block pop-up windows and this is blocked. Two exemptions are there which are acceptable. I have run virus checks on Bitdefender and Malwarebytes (Latest versions update) nothing is reported. - What is causing this and how do I stop it? After opening up the hidden window that flashes it tries different pages all fail then eventually the pop up window closes on its own.

Using latest version of Firefox browser 117.0.1 (64 bit) Don't get the pop ups on Google Chrome.

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.

HTTP/3 doesn't work regardless of my config:

network.http.http3.enable = true network.dns.httpssvc.http3_fast_fallback_timeout = 0 network.http.http3.priority = true

and https://cloudflare-quic.com/ and console still show I'm using HTTP/2. Tried on Firefox nightly and chromium (chromium works fine but firefox doesn't.)

I don't use McAfee. I recently downloaded Adobe Reader and it appears it comes with. How do I get rid of these constant pop up messages that appear to come from "Mozilla Firefox"?

Hi,

I noticed that in the last update, Firefox displays the list of login information options, in auto-fill mode, in alphabetical order and not according to the most appropriate address. For example, I get an authentication window for articles vpn.xyz. The first alternative I get is related to the address teach.abc (which does not fit at all) while the alternative for the address vpn.xyz appears in sixth place.

Thanks

I don't know how to turn the ad blocker off. The only thing I can think of that might be part of this problem is the f-secure system that is provided by Spectrum. I use Windows 11 and Firefox117.0.1 (64-bit).
