I am running Firefox 126.0-1 on an Arch Linux system. Most websites are failing to connect for security reasons.

Some sites, including google.com and nytimes.com, fail with an "SEC_ERROR_UNKNOWN_ISSUER" error, and their certificates confirm that they are respectively issued by Google Trust Services LLC and DigiCert Inc.

The website archlinux.org errors with "MOZILLA_PKIX_ERROR_MITM_DETECTED", stating that "Software is Preventing Firefox From Safely Connecting to This Site", citing in particular ISRG Root X1 as the problem. The certificate confirms that it is issued by Let's Encrypt.

The website duckduckgo.com simply errors with "SEC_ERROR_PATH_LEN_CONSTRAINT_INVALID" and states "Secure Connection Failed"

I have confirmed in preferences that my proxy settings are set to "No proxy" and the problem persists across troubleshooting mode and making a new profile. I have also tried removing the cert9.db file in a given profile folder.

When I visit an http site and specify a non-standard port, it automatically changes to https, which is not a site redirect but something Firefox changes. This site already has an https service, and the http service will redirect to https. I reproduced the same situation in chrome. Accessing the http service with a non-standard interface was normal. After accessing the https service once, the service with the non-standard port was also changed to https. Clearing the data will restore it. Is this cached? My HTTPS-Only Mode is turned off, and set an exception for this site. thx.

Hello, Microsoft Defender did a scan tonight and apparently detected a trojan script, located in the folders for Firefox extensions for both profiles I use on my computer

Trojan description: Trojan:Script/Wacatac.B!ml

Files: C:\Users\[user]\AppData\Roaming\Mozilla\Firefox\Profiles\[default profile]\extensions\langpack-fr@firefox.mozilla.org.xpi C:\Users\[user]\AppData\Roaming\Mozilla\Firefox\Profiles\[second profile]\extensions\langpack-fr@firefox.mozilla.org.xpi

This scan happened at 9pm, and a previous scan at 6pm didn't show anything. When it detected the script, MS Defender contained it and apparently deleted it when it asked me to restart the computer, I then did a full offline scan and nothing else showed up, same with a full scan with the free version of Malwarebytes. I didn't do anything unusual between 6pm and 9pm, so I'd like to know if there's a way to determine whether that script was an actual threat (instead of a false alarm)? If so, any way to know how long it has been on my computer? Any further risks to take into consideration? Other steps to follow? Thanks for the help

Hi.

I need to print out my saved passwords. I have no cellphone to access, just my laptop and printer. I only use Firefox and no other browser. If my laptop gets hacked or breaks down, then I need to use someone else's computer to access my passwords in an emergency, and can't access my passwords to do so...so printing them out periodically is the smartest thing I can think of.

Help, anyone? This is pretty important to me. Thank you!

Hi Everyone, My Bank has suddenly decided that ALL cookies must be allowed before letting their customers in -- a requirement with which I wholly disagree. My FireFox is set to block anything that moves, and supported by Ad Blockers and Ublock too. Is there a way in which I can configure FF to allow me into the Bank site without having to change my "secure" settings every time? I am no computer genius - so please make it simple for me.

Thanks everyone.

Hi, I accidentally allowed notifications (while using Firefox) from a particular web site only to find out that now I get numerous notifications regarding phony virus alerts, etc. I am unable to block the notifications.

I searched the web for how to block a notification from a web site, but have not come up with any solutions.

In particular, I went to about:preferences > Privacy & Security > Permissions > Notifications. The web site is set to Block, but still the unwanted notifications continue. Perhaps the notifications are coming from a different web site that seems to be hidden?

I also quit Firefox and restarted Firefox, but the notifications continue. I also restarted my Macbook Pro, but that didn’t help either.

Here is the link I originally clicked on, but I obviously wouldn’t want anyone to click on it:

I've looked into this situation, and none of the solutions submitted online work.

I went to about:preferences, and set "security.certerrors.mitm.auto_enable_enterprise_roots" to false, but "security.enterprise_roots.enabled" is set to true and locked; I can't change it.

First of all, I am not using Avast, AVG, Kapersky, etc. antivirus; I'm using Win 10's built-in security suite, so it's not my antivirus causing it.

To double check that, I opened the Registry and went to " HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Mozilla\Firefox\" and "HKEY_CURRENT_USER\SOFTWARE\Policies\Mozilla\Firefox\", looking for a Mozilla\Firefox\Polices key, and neither one had any Mozilla keys.

I even checked the Autoconfig settings, and found no settings in the JS file that had anything to do with Enterpise Roots (I renamed the file temporarily to disable it), but I still can't disable security.enterprise_roots.enabled

I have no "Organization"; I'm an independent home user, so needless to say I'm concerned that Firefox is suddenly saying some organization is controlling my Firefox.

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.

I have tried the suggestions as described in the following article: https://support.mozilla.org/bm/questions/1273784 However, am still having the issue. It's as if the settings are totally ignored. I am using version 108.0a1 of Firefox developer edition. Ideally what am trying to achieve is away to disable all features of ETP. I figured setting it to custom with all values unchecked would have done the trick but it's not working. What works is if I add the site to the list of Exceptions for Enhanced Tracking Protection, then I will see all Ads loaded just fine on the page. However, this is not viable for me as I have a large list of sites that I visit, and I need to see the ads on them.

Does anyone know of a way to get around this feature in FF?

Is there another setting am missing from the previous article?

I have a (quite old) Iomega 2 NAS in my local network. I have to connect to the admin page to change some settings, but FF responds with SSL_ERROR_UNSUPPORTED_VERSION, with no option to bypass.

It's my own NAS, in my own local network. How can I bypass this (in this case stupid) restriction? I know it's safe, I know no harm can be done, still I can't get to this page.

When using the Export Logins feature to create a .csv file, the last few fields don't seem to translate into any known date-stamp format in Excel. The data seems to have relative chronological value, but I can't make sense of it in a spreadsheet.

Can a developer check this and modify the output of those fields so it's more compatible?

Example:

Hello!

I always use private browsing so I thought that my history was totally not being saved, but discovered recently that when I started to type within the search field, that many of my past searches were listed in the search field with the type highlighted in purple. I had to manually go in and delete all of these past searches. I don't want any search history to be saved. Is there a setting in preferences that I'm somehow missing? Why is Firefox saving these past searches if I have it set to Always Use Private Browsing?

Thank you!

Here are the steps: Click on a file, Save "File not downloaded. Potential security risk." Click on the message - Allow download The result is a file with content "HTTP Status 405 – Method Not Allowed".

Please help me to work the downloading again. I am aware of the safety but I want to switch off this feature.

Hi all :)

From a fresh Linux Debian Bullseye I try to connect to a local machine with Firefox (v97 64-bits) by its hostname (avahi server with default domain "local") with the port 6180 bound to a remote web service port (61 is the distant machine IP and 80 is the forwarded port).

When I want to open this URL : http://bionic.local:6180/ FF displays "We can't find this site ... Unable to connect to server at bionic.local ... check your network connection and firewall"

BUT ping bionic.local works perfectly and resolve the good IP address from the Chromium navigator the same URL works without a problem, I can open the distant web site.

This workaround works : add a static resolution in the /etc/hosts file : 192.168.0.71 bionic bionic.local => so FF works in the expected way for now ! But as I said this a workaround and a bad solution.

I supposed too the port was blocked because I accessed an unusual port. So I tried this without success.

How the hell make that FF v97 allows me to use an unusual port ? Or is it bound to the domain "local" which is no more accepted by FF ?

Thank you in advance for your help. With adelphity, lnj

Google offers to use a Google login for many websites in the top-right corner of Firefox, for example, when I start Twitter. I don't remember this behavior more than a few months ago. This is on desktop Firefox, not mobile. I never login to Google unless I want to use Gmail or Blogspot, and then I logoff and kill the browser when done. Can this offer be disabled?
