Firefox Support Forum

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 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.

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?

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

Hello I'm referencing the topic where TLS 1.0 and 1.1 support was removed but rolled back to accommodate some government agencies / sites and support for COVID-19 data

https://support.mozilla.org/en-US/questions/1290040#:~:text=Mozilla%20and%20other%20browser%20makers,and%20performance%20of%20Internet%20connections.

Quoted answer "Right, support for TLS 1.0 and TLS 1.1 has been removed few months ago, but we reverted the change for an undetermined amount of time to better enable access to critical government sites sharing COVID19 information."

Since it was referenced as "undermined amount of time", is there anything currently on your roadmap/release schedule in regards to removing support again? I have some cutover decisions I need to make and knowing if ESR for example will remove this support in 2 months may effect the direction of those. If you have anything to share, i'd really appreciate it.

Regards,

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

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...

Hi,

No matter what I do, a google dialogue box encouraging me to use google for password management, pops up every time I go to a site, new or existant.

I've gone into my google account to disable such requests, and, indeed, otherwise use google for nothing....not even search............but they keep coming anyway.

am using ubuntu 20.04, and no other utility or code is giving me this trouble.

I want to stop this dialogue box and eliminate any code in firefox or ubuntu which supports it.....as I have no idea why this box showed up....one day it just started.

Many thanks!

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!

Taking a look at the screenshot attached below you will see the librewolf browser which is a fork of firefox, blocks system font detection by default. How does librewolf do that? I hope by reading your reply i will be able to achive the same outcome with firefox. I'm also interested on how to block system local time readout/detection with firefox as i have so far not found a solution to this issue. As a privacy focused person i do not see any reason why any website would be interested in the timezone of my operatingsystem. This information is most likely not even necessary for functionality. From my knownledge the android browser named bromite (source: https://www.bromite.org/) does block timezone detection by default, since firefox is a privacy browser i fail to understand why this feature is not included to the settings tab.

PS: I'm not interested to making any suggestions anywhere, i want to modify firefox to block both system font and system timezone detection, any help is welcome...

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!

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?

p.s. Greg Hunter is interested in this reply too

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!

I was surprised today to visit a site and notice the "permissions" icon appear at the left of the address bar, showing me that cross-site cookies were allowed for this site. I have Enhanced Tracking Protection set to "Strict", so obviously this was a worrying thing to happen.

Looking into it a bit further, it seems Firefox provides a backdoor for cross-site cookies: https://support.mozilla.org/en-US/kb/third-party-trackers?as=u&utm_source=inproduct#w_managing-cross-site-cookies

• "While cross-site cookies from trackers are blocked in Firefox by default, a site may signal to the browser that it needs to use them for important functionality. In this case, Firefox will allow a third-party website to use cross-site cookies the first five times (or up to 1% of the number of unique sites you visit in a session, whichever is larger) without prompting you. After that, Firefox will prompt you to block these cookies. Without your consent, Firefox blocks these cookies from that point because a site requesting access that many times may be a tracker."

This is most definitely not what I want!

I want every cross-site cookie to be blocked by default, unless and until I explicitly approve it. Is there an about:config preference I can set to achieve this?

Hello, I can't access the home router. 192.168.1.1 results in "Secure Connection Failed" and nothing can be done. How can I solve the problem?

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?
