When entering a local domain in the URL bar Firefox sends the request to a search engine instead of the DNS server. How can I stop this behaviour and switch back to how it was before?

I don't know why, it is NOT Ancestry, as I can sign in to it on other browsers. I get this error message below.

Access Denied Error 21 What happened? This request was blocked by security rules. Your IP: 73.94.12.65 Incident ID: 6eae587fcef92d46

I have no idea what security rules, but I am working on a genealogy project and have never had a problem signing into Ancestry in multiple tabs before today. How do I fix this? Besides getting rid of Firefox, I mean. I have the same security extensions on this browser as I use on Vivaldi, Brave and Chrome - I avoid Chrome, but use Vivaldi and Brave regularly, along with Firefox.

Up until the last update of Firefox I was able to access my router, 192.168.1.1, enter password and check it.

Now I get an error message "connection not secure" "Your connection to this site is not private. Information you submit could be viewed by others (like passwords, messages, credit cards, etc.)

None of this is part of looking at my router, Asus GT-AX11000.

suddenly I ca no longer log into iCloud. I get a security issue. I refreshed / uninstalled and reinstalled. no help. any assistance would be appreciated. see images.

Hi, I planned to block my users from installing extensions/add-ons. I found an article that might be the answer (https://support.mozilla.org/en-US/questions/1308646). I tried to create a simple policy (below), but somehow it does not work (I can still install any add-on/extension). What is wrong with my script? I'm using Firefox ESR 78.11.0 (64-bit) by the way.

My "policies.json" looks like this:

{

"policies": {
  "ExtensionSettings": {
    "*": {
      "blocked_install_message": "Blocked!",
      "install_sources": ["https://addons.mozilla.org/"],
      "installation_mode": "blocked"
    }
  }
}

Sincerely, Jonathan

I am getting notifications with the Mozilla logo or sometimes with McAfee logo saying "5 Viruses found, your computer is unstable" and various other warnings. They all also say "via qltuh.titanicooler.top" I have attached a picture.

I have closed the browser, I tried clearing my cache, I have scanned using both AVG, AVAST, F-Secure Online Scanner, and Microsoft Safet Scanner. I am not quite sure what else I should do.

Thank You

I had a personal certificate installed in Firefox and it was working well. It expired, so I got a new one from the same provider. Both appear in Firefox under "Privacy & Security" -> Certificates -> View Certificates... The previous one is not valid any more, and every time I try to access some page with a certificate, it uses the old one. So I tried to delete the old one. Nothing has worked so far. Doing the straightforward way of selecting it in the Certificate Manager and deleting it makes the certificate disappear from the manager menu, but if I enter the certificate manager again, it is there again. I tried to delete both certificates, same issue, both reaper in the manager. I tried to delete them, close firefox, delete cert9.db, cert8.db and key4.db and nothing. Only thing left is delete my current firefox profile and start again... Any other idea or something that I might delete before to solve this?

Ever since updating to the current version of Firefox (112.0 64-bit, according to the settings), every time I close the browser, I'm logged out of every single service I'd been logged into. This was not an issue with previous versions of the browser, and old forum posts on the subject don't seem to contain correct, up-to-date information. Is there some setting I'm missing, that I need to update?

Noticed geo.provider.network.url setting in about:config no longer works in firefox 102.0 ubuntu. I use it consistently so it was easy to notice that it no longer had any effect after updating.

tested both on https://maps.google.com and https://browserleaks.com/geo

Is it possible to revert to an older version without losing my data?

Scroll down until you find "PERMISSIONS" and find for "Camera". Click on "Settings" that is parallel to "Camera". Now, select/type all websites, that you want to give permission/access to your camera.

Never used a webcam before, but i did that... the site is there, it says allow... i'm on the website now, says webcam not found... am i forgetting something? do i even have one? i'm at the library...

I asked this question some time back here: https://support.mozilla.org/en-US/questions/1362859 I'm asking again to reframe the question. The problem is - if my experience is a guide to the rest of the world - VTT files (which are used to caption HTML video) are no longer read/loaded by Firefox when it is viewing the HTML file locally (i.e. file://). On the web they are loaded as expected. Presumably there's a security setting somewhere in Firefox that now refuses to load the VTTs locally. Maybe under Help > More troubleshooting information there is a setting to change to fix that?

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

How to do

I've saved and can use the log-in details for a particular site, but they doesn't show up in the password list, so I cannot edit/delete them. Whilst it may not be relevant and may confuse the issue more, the reason I want to delete log-in + password is because I have to create a new account every 2-3 months, which I then save. So when loading the home page, the current and all previously saved log-ins get listed. I've tried to manually delete one when on the home page, but unlike keystroke searches which do get deleted, this one remains in the list. I suppose I could clear everything and save all the log-in details for each site again, but why are the log-ins for one particular site not showing up ?

Thanks

I installed the Firefox browser (version 113.0.2 (64-bit)) onto a new PC running Windows 11. When attempting to clean up the Firefox cache with another utility, I noticed that the amount of space recovered was much smaller than expected. When I tried to check my profile using the Troubleshooting Information page (to open the folder) I received a message that the location was not available. I double checked with Windows Explorer and this was the case. Searching for "cache2" in Explorer located the folder/directory in a different location.

The Firefox Profile Folder should be in this location, according to Firefox's Troubleshooting Information page (anonymized information in square brackets):

C:\Users\[username]\AppData\Roaming\Mozilla\Firefox\Profiles\[character string 1].[profile name]

The best I can tell, the actual Profile Folder created in Windows 11 is located here:

C:\Users\[username]\AppData\Local\Packages\Mozilla.Firefox_[character string 2]\LocalCache\Roaming\Mozilla\Firefox\Profiles\[character string 1].[profile name]

The cache folder for the profile is located here:

C:\Users\[username]\AppData\Local\Packages\Mozilla.Firefox_[character string 2]\LocalCache\Local\Mozilla\Firefox\Profiles\[character string 1].[profile name]\cache2\entries

I am not sure if this situation is unique to me, or if this is a common occurrence with Windows 11.

The use of the Packages folder may be the result of installing an application that is not fully "Windows 11-native" or it may just be the new way Windows deals with some applications. I am not sure if the data in character string 2 is consistent, or if it is a unique string created by Windows when Firefox was installed.

If I go to the Settings and clear data, the folder that is a sub-folder of Packages is cleared, so Firefox "knows" where the data is, but the Troubleshooting Information page is confused.

If this is a common occurrence, a tweak to this page in a future release would be helpful. If it is a rare occurrence, a help article may be, well, helpful.

Thanks.

On my laptop, I run FDE as my daily driver, with the release version to handle my webmail. I also use portable firefox (from portableapps.com) as a browser to use while at work, from a thumb drive. While using that portable verison, I usually just go to google image search, and a work site that would definitely be secure.

My question: I don't like to update the installation on my thumb drive very often, and occasionally work computers are very slow anyways. So if I were to update it no more often than once a month, which version of firefox would be most secure: Release, Beta, or Nightly?

If doing this is just dumb, then which version gets updated less often--it would be Release, correct?

How do I shut off "Firefox prevented this page from automatically redirecting to another page"? I have pages that need to refresh automatically and this function is preventing these pages from automatically updating. I have searched settings multiple times and have not been able to fix this. This just started after a Firefox update a month or so ago. PLEASE HELP!

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.

Win 10 Home Ver. 22H2 OS Build: 19045.3086 Windows Feature Experience Pack 1000.19041.1000.0

Antivirus/Firewall: Windows 10 Security

Firefox: 114.0.2 (64 bit)

I was trying to sync my settings to my new laptop with my login and PW (which was correct) and it kept telling me it wasn't right. So, I decided to change it but my MFA on Google for Firefox got wiped once I switched phones. I had to use a backup code to get in and want to re-enable the MFA.

Unfortunately, and for no real reason, it won't work. I scan the QR code in Google Authenticator, it sets up and gives me a code, I enter the code, and then it tells me it's the wrong one. I even tried to do it by manually setting it up and it made no difference. Now I can't re-enable it because it won't work right.

What the actual hell is going on here, guys?

The rumble video interview of Jonathan Cahn by Greg Hunter is NOT visible in my linux version 91.12.0esr(64-bit) of Mozilla Firefox, straight from an openSuse software repository and directly installable under yast, which is their administrator program over the linux software including the software manager

The web page in question is https://usawatchdog.com/only-way-to-save-america-is-turn-back-to-god-jonathan-cahn/ but the java script code is grayed out on this page

!function(r,u,m,b,l,e){r._Rumble=b,r[b]||(r[b]=function(){(r[b]._=r[b]._||[]).push(arguments);if(r[b]._.length==1){l=u.createElement(m),e=u.getElementsByTagName(m)[0],l.async=1,l.src="https://rumble.com/embedJS/ugdmvn"+(arguments[1].video?'.'+arguments[1].video:)+"/?url="+encodeURIComponent(location.href)+"&args="+encodeURIComponent(JSON.stringify([].slice.apply(arguments))),e.parentNode.insertBefore(l,e)}})}(window, document, "script", "Rumble");

I have used other browsers, such as Opera, Brave, Google Chrome and the rumble video is clearly visible and playable.

What do I have to change in Firefox so that this video becomes visible on the page?
