Idk why but sometimes firefox just doesn't prompt to generate secure password, I even have to download some extensions to generate secure password (Secure Password Generator) meaning more secure issues.

My guess is that you guys probably hardcoded something like {if "type: password" then prompt}, but it's still partly fault at developers too for bringing these huge chunks of javascript.

In screenshot there's element examaple in which i input password but no prompt whatsoever.

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.

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?

Firefox is suggesting usernames on multiple websites that I access regularly. However, I have the saved logins feature turned off in Firefox.

When I access Settings > Privacy & Security > Logins and Passwords - it shows all of these options turned off.

When I access Settings > Privacy & Security > Logins and Passwords > Saved Logins... - it indicates No Logins Found / No Synced Logins found.

I do have Firefox Sync turned on to sync between devices, but since it indicates "No Synced Logins" it doesn't appear this is coming from another device. I have checked multiple devices and found they all show "No Synced Logins"

Only happening in Firefox. I am not getting these suggested logins in Edge or Chrome.

Happening across all my Windows 10 and 11 devices that have Firefox sync enabled. 2 x Windows 11 Pro 22H2 (build 22621.819) 1 x Windows 10 Pro 22H2 (build 19045.2364)

Firefox 108.0 on all Windows devices, but it started before updating to 108.

I have not yet tried resetting Firefox - hoping to use that as a last resort.

Any suggestions on where else to look or what I should try?

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

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 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?

Zoom.us renewed their DigiCert Global G2 TLS RSA SHA256 2020 CA1 certificate on 03/31/2023 and I now get a persistent error message (Error Code 6: ... certificate is not trusted.

Since then Zoom has not worked for me and their Artificial Intelligence says to open my browser and check my internet connection, time settings, updates, reinstall everything etc. - the usual responses ...

Zoom responds with "Error code: 6" and/or "Error code: 100068000"

 but do not stipulate whether these are Zoom Error codes or certificate error codes.

The Artificial Intelligence insinuation is that FireFox is not trusting this certificate.

Is this something FireFox can help me with? Perhaps, how to make this certificate "trusted"?

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 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?

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

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 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?

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!

Today, after browsing about whether or not I should continue using Firefox as my password manager, I decided to mitigate the most important security flaw in browser based password managers, by setting up a Primary Password. I choose to use an easy to remember 8 word long passphrase as my Primary Password. I noted down the passphrase in my diary. Due to problem while loading YouTube, I decided to restart Firefox by going to about:profiles and selecting "restart normally". This issue where Firefox starts to struggle connecting to internet is a relatively common occurrence on my Firefox install, and restarting Firefox fixes the issue. When Firefox restarted, I was prompted to enter the primary password. I confidently entered my passphrase, but it was rejected. I tried to typing to it more carefully several times. I got my diary and checked it to make sure I was entering the passphrase correctly. Following troubleshooting steps on a similar thread, I restarted firefox, no luck. I than rebooted my computer, issue persisted. I decided to restart Firefox with extensions disabled, and also in troubleshooting mode. Firefox still rejects my passphrase. I have my Firefox account synchronized with two Android phones. Will reinstalling Firefox and syncing with my Firefox account solve the problem? In a similar troubleshooting thread, renaming key4.db and logins.json is suggested. However, it has not been explained very clearly. My logins.json file was modified an hour before disaster, even though I had made no changes to any of my logins or the master password. Is my logins.json corrupted causing the issue? I will like to point out a design flaw in Firefox which might have caused the issue. I usually want to see what I am typing when I am entering an encryption password. This is to make sure that I don't mistype something. However, in Firefox Primary Password configuration window, there is not option to see what you are typing. Firefox relies on low probability of typing the wrong password twice. I don't think devs should be so worried about shoulder attacks to not even allow users option to view what they typing. My case might be that low probability situation where I made the same mistake while typing the passphrase twice.

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'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
