Firefox Support Forum

Today Firefox stopped altogether and dimmed the entire window and popped up a "Try the Firefox VPN" message. I use Firefox specifically to get away from disruptive, intrusive violations like that. This needs to be removed immediately and never ever happen again. It's completely antithetical to the core values of Firefox.

Furthermore, several users have reported it breaking their browsing. See this Reddit thread:

https://www.reddit.com/r/firefox/comments/13rnt88/why_is_firefox_windows_11_version_showing_me/

This affected me on Windows 10 running Firefox 113.0.2 64 bit.

Hello,

I am a developer on an emergency intervention hotline for sexual assault.

Firefox is now throwing up psuedo-modal advertisements for it's VPN above pages. See attached screenshot for example.

It is absolutely IMPERATIVE that our visitors do not receive these new modal advertisements that Firefox is throwing at them. What can I do to prevent Firefox's new browser-hijacking advertisements from showing up on our hotline pages?

I experienced this on Twitter, and it 100% was not part of the dom. It also greyed out the tab bar, and prevented me from opening the menu with alt. I know how to make it not show up anymore on my machine, but how can I prevent it from appearing on visitors to my website, who are in some of the most vulnerable times of their life.

Hi,

My primary email is in the .ru domain and I have lost access to it due to Ukraine goc restricted access to it. How can I change it or set up alternative authentification method without confirmation via email.

I still have access to Account settings from my phone Just have new OS on my PC and faced this problem.

TY BR, Serhii

Hi folks. The title of this question started 2 weeks ago. Was fine before, but now a yellow triangle on the padlock.

Running test sites show everything secure. I have certificates. No other browser shows a warning. I read your help article and all is just like it should be. .htaccess redirects domain.com to www.domain.com and http: to https: just as it should. But still this "error". It must be images in my header, footer and sidebar, but I cannot change the path for those in any way I can find.

How can I correct this?

Thanks!

2FA login on sites works with Chromium but NOT WITH Firefox (Linux)

Present setup:

Does NOT work firefox 102.7.0esr on debian 11.6 bullseye 5.10.162-1 (x86-64) firefox 110.0 on Ubuntu MATE 22.04 LTS 5.15.0-58 (x86-64)

Works chromium 109.0.5414.119 on debian 11.6 bullseye 5.10.162-1 (x86-64)

I am able to register and authenticate with security devices Yubikey NEO (without FIDO2) and Yubikey 5 NFC (FIDO2 compliant) on several sites (eg. pypi, google..) using Chrome or Chromium but now not with Firefox at all. It has not worked for at least the last few updates. Changing settings in about:config or plugging/unplugging keys, stopping every Firefox plugin etc. don't help. Neither does a fresh Firefox install without any super-security-settings.

Testing sites like Yubico's own or Okta's works fine using Chromium but not Firefox.

From what I can see this is not especially related to FIDO2 (Webauthn). pypi seems to use U2F which should work just fine with Firefox since way back.

I haven't tested Firefox for Windows but Chrome browser for Windows 10 works fine (which I tested first when Firefox didn't cut the mustard), I therefore expect it to work also on Chrome browser for Linux. Just to check if this was related to a debian bullseye package, I tested it on Ubuntu MATE too, which didn't do the trick. Haven't done any more testing than that on MATE.

This seems like a strictly firefox problem. -What to do?

Yours, Kaare

I am new to Firefox and I am trying to set my account up. I have put passwords in and so far I have had to change them. I have tried putting a authentication code in and it won't accept it after checking it. A Liverpool address came up and I don't live in Liverpool..

Block autoplay not working on 112.0.2. I've tried going into about:config and changing settings. Doesn't help. Also under "Settings \ Permissions \ Autoplay" shows default for all websites as "Block Audio and Video" and under Websites "About:Welcome" shows as "Allow audio and video." I've changed the About:Welcome to block audio and video. I've also tried clicking the Remove All Websites button to delete the exception. Neither works. I save changes, exit Firefox, and restart. Same settings as before, and autoplay still starts.

Hi,

Is there any reason firefox would flag an mp4 file legitimately?

• The file extension and file type are absolutely mp4.
• There seem to be no mp4 related zero days.

Does Firefox perhaps just treat all downloads from suspicious domains as malware? Is there a zero day I missed? Is this based on some missing metadata on the file or something?

Thanks for any advice you can give here, I'm scared.

Hello dear Firefox Community,

I have been trying for a while now to set up a proxy on my own and have Firefox connect to it. Since there are a few options on how this can be accomplished in theory, the only way I way able to get it working was by using an Http Proxy. I looked at the connections Firefox is initiating towards the proxy using Wireshark. I was shocked to say the least. When trying to use an HTTPS Proxy, Firefox doesn't encrypt the connection to the proxy at all. So the domain I'm trying to connect to and the Credentials I use to log into the proxy are visible in cleartext. That is an absolute No-Go! Is there a way I can configure Firefox to encrypt the connection between itself and the proxy? If not, are there any plans on implementing this kind of functionality?

How can I get a list of all the sites that are set to "always open" in a specific container? For example, I want to see a list of all the sites set to always open in the Work container. I would also like to edit the list without needing to manually visit each site.

Hello, We run a website that uses a bookmarklet button which allows us to capture the current URL location and save it. This is placed on the Tool Bar where its easy for a user to use. Until now, its been working perfectly but with this latest update to FireFox we are seeing the pop-up blocking being activated with the yellow message bar at the top. Now this would be ok if we only had to allow the pop up once (by clicking allow site), but unfortunately the bookmarket button has to be able to work on all sites, which is the whole point of the button. So its impractical to keep allowing it every time its used. Disabling the pop-up blocker completely then works, but then the browser is open to other pop-ups. Is there any way to allow bookmarklets to display a pop up and not display a pop-up message? Without having to disable the entire pop-up functionality. Can the FF developers allow for user placed bookmarklets to not be pop-up blocked. Maybe an exception added for that. They are placed manually by the user so are allowed by the user only.

Thanks for reading. Paul.

Before you reply, look at the last lines if you do not want to make fools of yourselves (by answering a question that was not asked).

Two or three years ago, a number of people complained about the lack (loss of possibility) of removing many login/passwords entries. I believe you could do that a few years back, before the infamous Lockwise.

As of today (14 Feb 2021), you have to delete unwanted entries ONE BY ONE, confirming each with a click. Typically designed for tablets and phones, forgetting that the desktop-rest-of-us still can use a keyboard shortcuts and such.

For example, if you want to remove cookies that relate to SITENAME, you just have to go to the Manage Data section of cookies, type in SITENAME, select all, then remove the selection. Done in 1'.

Currently, solutions that are still recommended are:

- reset the key password, hence deleting ALL passwords - remove the logins.json file

I do not want that, because (as for the requests I have seen on this topic https://support.mozilla.org/en-US/questions/1276054), I have around 950 logins stored in there (yes, been using firefox for more than 15 years, and Netscape before that).

So, no, I don't want to remove everything ; no, I do not want to spend even 30' clicking.

"When a server requests your personal certificate" my preference is set to "Ask you every time" but Firefox is remembering the certificate I used last time for a site and does not allow me to select a different certificate. How can I change this please? My Firefox browser version is 84.0.2 (64 bit). Thanks

Hello, im a web developer and have come accross a problem which only occurs in the firefox browser.

When i design a website, i use the www version of it always, and have redircts for all other instances, eg; mydomain.co.uk > https://www.mydomain.co.uk http://www.mydomain.co.uk > https://www.mydomain.co.uk https://mydomain.co.uk > https://www.mydomain.co.uk

So they all end up at the secure www version of the website. This is done in the .htaccess file and works great in Chrome, Edge, Explorer etc just not firefox.

In firefox i get the error

Warning: Potential Security Risk Ahead

Firefox detected a potential security threat and did not continue to boothandco.com. If you visit this site, attackers could try to steal information like your passwords, emails, or credit card details.

What can you do about it?

The issue is most likely with the web site, and there is nothing you can do to resolve it. You can notify the web site’s administrator about the problem.

Ignoring it then procceeds to the full https://www. but that warning screen will be enough to put potential visitors off no doubt.

Is there an "easy fix" for this or is the only way to solve the problem to use up more SAN's and double up on www and non-www versions of each website?

Any help is greatly appreciated.

Thanks Chris

I set my primary password yesterday since I was leaving my laptop with a service person. Today, Firefox tells me the password is incorrect. I am entirely confident I know what I intended the password to be, and it seems wholly unrealistic that I made the same typo twice in one entry, yet I've trial and errored almost every possible typo I can think would cause this. I am really not sure what to do now, all my accounts are locked behind a password that is not the one I set less than 24 hours ago. What can I do?

We run Firefox on all our clerk computers at the public library where I work. Since the most recent update, our online circulation website which we use to check out books, receives a pop-up blocked message every time we try to print a hold receipt for an item. The website has always been added as an exception to our pop-up blockers, and until just after the most recent update, the blocker had no problem allowing the website through. Now it does. I have tried clearing the browser caches, removing and adding the website to the exceptions list again, and restarting the browser, as well as adding different variations of the website to the exceptions list. In the end, we just had to turn the pop-up blockers off. I searched online for anyone else who had this issue, but the ones I found dated back to 2014-2015, and the solution they came up with no longer seems to exist in the Firefox settings. So I'm hoping to find an answer here! Thanks.

At the top of the about:preferences page, in a gray box, it says, "Your browser is being managed by your organization". Why? This is my home computer! How can I manage my own browser?
