Firefox Support Forum

When attempting to update my Mozilla account from my Firefox settings, I was unable to add my secondary email address because of an error message stating that the secondary email account exists...

Repeating this action in case of a bug resulted in being locked out of that particular window.

I have no idea what that error message means, nor how to circumnavigate it. Please help!

Thanks, MGB

Why am i seeing this, and how can I get it to where I am the one controlling my browser and not an "organization" I don't know? This was the big issue I have had in the past with your browser. I cannot find a way to change it.

Firefox version 122.0 Mac: Sonoma 14.1.1 apple silicon

The problem emerged about a little over a year ago (around September 2022). It started with an installation of firefox on another machine running BigSur, and I guess the problem got ported when I restored a time machine backup on this current machine. I attempted to troubleshoot the issue by following mozilla support and reddit threads but to no avail. I, at the time, settled on monthly time machine backups, but now finally decided to address it properly.

Troubleshooting steps that I have followed:

• going into the about:config page and changing the places.history.expiration.max_pages and places.history.expiration.transient_current_max_pages to 2147483647 then to 999999 after reading about how a value too high might be ignored (both values didn't seem to change anything)
• going into the about:config page and changing the places.history.expiration.transient_optimal_database_size to 85534800
• removing the add-on/extension manager as seeing that it might remove history for some reason (from a [thread] by IceTemple)
• In the privacy and security tab, history is set to Firefox will use custom settings for history

Things I suspect might be the problem:

• I originally used the Chinese version of firefox (downloaded from the .cn website) and reinstalled the international version (from .com) after getting annoyed by the built-in ads. For convenience sake, I ported the profile folder over which might have carry the problem over. That being said, I don't think this problem existed when I just started using firefox but appeared awhile later.
• result of an update, don't know which though
• certain extensions (I haven't went through them individually since I installed a lot)

My questions:

1. How to stop Firefox from doing this ever again?
2. Alternatives of storing history if nothing works
3. Why did my troubleshooting steps not work? Is there something wrong with my version of firefox that prevented the about:config changes from working?
4. If I have to resort to backing up the places.sqlite history file, how do I restore/reintegrate them with current history file?

English isn't my first language so I apologize for any confusion that may arise due to how I articulate. Any help is much appreciated

I had set Google to be my default search engine. But that seems to have been replaced by yahoo! [I have tried to put a screen shot here but Firefox won't let me] I searched for Google in the search box which put the following in the url.

https://uk.search.yahoo.com/yhs/search?p=google&hspart=iba&hsimp=yhs-syn_weatherprince&param2=9dUI1n2R0BLDxNuWfiP4aSFOTltNdSPoIx38%252BUf%252FiXrvPdoGmStdlfwLFZYDv ...

In Settings>Search, there is no Yahoo. Presumably it has hacked my computer. How can I get rid of it? I am running Windows Defender (3 1/2 hours to go) and I have Reset Firefox. Win11, 64 bit, latest Firefox

Before updating Firefox to 123.0.1 (64-bit) + MacOS Sonoma, I could use FIDO2 on OnlyKey and login to my proton mail. Now, however something has changed on Firefox that I get presented with two prompts to touch my usb key, but the key itself doesn't respond to the second prompt and login fails.

I first get this prompt as before. I select 'Authenticate' and would be presented with the second picture. Since my key is not expecting to be touched, nothing happens when I touch it and login fails with the message displayed in the last picture.

Release notes for Firefox v120.0 https://www.mozilla.org/en-US/firefox/120.0/releasenotes/

Among these release notes, "Firefox’s private windows and ETP-Strict privacy configuration now enhance the Canvas APIs with Fingerprinting Protection, thereby continuing to protect our users’ online privacy." How good or bad is the feature? There's the canvas blocker extension which might now be obsolete, then again without details this is impossible to anser. How exactly does the Canvas API enhance Fingerprinting Protection with this new update? The release notes don't explain that, where do i find details? Firefox should use this for all windows not only private ones.

Among the relase notes, "Firefox is rolling-out Cookie Banner Blocker by default in private windows for users in Germany during the coming weeks. Firefox will now auto-refuse cookies and dismiss annoying cookie banners for supported sites." I'm not german but would still like to use this feature as the cookie agreement popups are extremely annoying and time intensive to dismiss. Apparently in about:config "cookiebanners.service.mode" is the precise setting name. Does it have to be set to "1" to be active? This setting seemingly has the potential to replace extensions such as "Cookie AutoDelete" or uBlockOrigins Filterlists/Easylist cookie notices. Firefox should use this for all windows not only private ones.

Among the release notes: "Firefox has enabled URL Tracking Protection by default in private windows for all users in Germany. Firefox will remove non-essential URL query parameters that are often used to track users across the web." I don't get why this would only be active in private windows and germany. Firefox should use this for all windows not only private ones.

Among the release notes: "Firefox now imports TLS trust anchors (e.g., certificates) from the operating system root store. This will be enabled by default on Windows, macOS, and Android, and if needed, can be turned off in settings (Preferences → Privacy & Security → Certificates)." I've no idea what to think about this, is it a good or bad change and why? Don't try to fool me here, i want honest ansers no BS... is there potential for abuse? If Firefox uses CA's from the OS then what happens to firefox internal CA's, remain unchanged?

Among the release notes: "Firefox supports a new “Copy Link Without Site Tracking” feature in the context menu which ensures that copied links no longer contain tracking information." While this is a welcome change, i'd be much much more useful to replace “Copy Link Without Site Tracking” with “Open Link Without Site Tracking”... Otherwise there's the needless waste of time manually open a new tab and paste the link... This completely lacks any logic if you ask me, why didn't mozilla make it as i suggest above in the first place? Why the manually klick klick waste of time?

Lastly a question unrelated to this update, when RFP is enabled and the browser-screen-size is spoofed, if i go into fullscreenmode by accident, will this expose my true resolution or not?

Hi dear Community!

As of recent, my AntiVirus software is flagging Firefox.exe (Full path: C:\Program Files\Mozilla Firefox\firefox.exe) as a vulnerable application. I have been using firefox for years (Because I love it, you guys are heroes) and i have been using Kaspersky for years. Firefox has only been flagged as of recent.........

I hope someone knows why, has this too or can calm my paranoia

Some Additional information:

Have you clicked any suspicious links? No i have not. The links i have visited were all https, checked and acknowledged by Kaspersky and i can say with full certainty that the sites were legit

Have i downloaded any files as of recent? Yes, but from reputable sources and always checked using Hashes and validating using KSN (Kaspersky security network).

(For the Mods, im sorry for previously posting this in the wrong forum.)

CNN website being blocked. This notice comes up:'''' We apologize, but your web browser is configured in such a way that it is preventing this site from implementing required components that protect your privacy and allow you to view and change your privacy settings. This functionality is required for privacy legislation in your region.''''

After inputting my master passwords, the browser only loads 16 of the 100+ passwords I had stored with it.

I am able to access them through the deprecated Lockwise app I have on my phone but they won't load on my desktop browser, even after doing a sync on my Firefox profile.

Is there a way to recover the lost passwords?

Hi, I use windows hibernate a lot. One vulnerability of hibernate is that the contents of RAM get written to the hard drive in unencrypted form in a file called hiberfil.sys. This means that any encryption keys in RAM used to access encypted files will be written to hiberfil.sys and can be extracted if a malicious party has physical access to the drive.

Thus, the question:

Does Firefox store encryption keys, passwords, or log in details in RAM at any time while in use?

Thanks.

I set up a Primary Password, but I can easily get around it by clicking 'cancel' then clicking 'home' icon. then I can get into ANY of the links. For others who have access to my computer NOT having that access is Exactly why I set up Primary password in the first place. Surely there must be a way to fix this???? haas2128@comcast.net Thanks.

I was trying to troubleshoot a black screen of death issue with Windows10 that first started appearing after Firefox adopted the new Private Browsing icon. In the process of doing so, I tried every combination of Firefox settings imaginable. Nothing worked as far as Asus, Windows, or Firefox settings, rolling back/ updating various drivers, etc. So, I decided to refresh Firefox and when that did not work, I decided to uninstall and reinstall Firefox. I'm not sure if that worked as far as the original black screen of death issue is concerned because now Firefox no longer remembers my cookies and site data allowed exceptions (my only exceptions were my bank websites, which worked as expected until the uninstall/reinstall). I've tried selecting always use private browsing and always delete cookies and site data when Firefox is closed (my previous settings), but every time I close Firefox and return those three exceptions are missing. Any ideas would be most welcome. BTW, does anyone know how to use that folder Firefox puts on the home screen labeled "Old Firefox Data" because I was expecting there to be a .exe file to click on to reload all the previous settings in one fell swoop.

Each time I connect to the Sam's Club website I get a popup box that says "Let us know your human (no robots allowed)" even before I try to login. There is an "X" in the upper left corner of the message that I can click on twice and the box goes away. I then can click login and my password saver fills the boxes at which time I get the same box. I click again on the X and a message says there is a problem, try again later.

Hello,

When I call up a website that a user requests a certificate.

Can I tell Firefox to save my decision.

How can I delete this decision afterwards?

I can't find anything about this. Delete website setting does not help.

Only resetting the whole profile would work.

But I don't want to do that.

When I check Firefox for add ons (Manage your extensions), I see the two that I installed. When I use "Help -> Troubleshooting Information" "Application Basics": Multiprocess Windows "Remote Processes" , I see in addition: Amazon.co.uk Amazon.com DuckDuckGo eBay Wikipedia

How do I eliminate these?

I have a local only test ca and test web server. How do I load the CA certificate into Firefox. Adding it via "settings" did not work, the browser says Adding a root via "settings" does nothing. When I access a web server it says "the original certificate provided by the server is untrusted", in the issuer name field. It never actually shows the certificate. Adding a file to the appdata area (this is on windows 10) also fails; changing the enterprise ca settings does not work. This used to work.

Im trying to halt fingerprint tracking, whoever designed Firefox's privacy.resistFingerprinting rule makes fingerprinting even more prevalent.

With privacy.resistFingerprinting set to FALSE, my resolution is reported : 1920x1080x24, set to TRUE its 1920x968x24

1 in 6 browsers has resolution 1920x1080x24 1 in 6000 browsers has resolution 1920x968x24

Who in Firefox decided this config rule? and what is the logic behind it? Looks like intentional sabotage to make peoples browsers more trackable.

Whilst leaving resistFingerprinting set to TRUE, How can I force my resolution to the more generic 1920x1080x24?

Is there another setting in about:config I can change? if there isnt, where can I request this feature? Id rather not resort to an extention for something so small like this.
