Hi, after the last update I got this message that resides above my browser window:

The security sandbox is disabled. Your configuration is unsupported and less secure

I'm on Windows 11.

Right below the search bar my browser has a warning "The security sandbox is disabled. Your configuration is unsupported and less secure."

I am on Windows 10. I have tried uninstalling firefox, removing appdata and all other firefox files and settings, resetting about:configs settings, disabling my BitDefender antivirus. Nothing fixes it. Completely fresh install of firefox still gives me that message. Sandbox level is default (9).

Any help would be appreciated.

On Windows 10 with 64-bit Firefox, after updating from version 144 to 145, some local HTTP-only servers stopped working and became inaccessible. When I enter http://<local server name>, after a few seconds it automatically changes to https://<local server name>, and since no HTTPS service is running, it ends with a “Server not found” page. It seems to be related to DNS — accessing http://<IP address> works fine.

I tried a clean installation with a new user profile, but it didn’t help. Downgrading to version 144 fixes the problem, but at the cost of losing the user profile (which is a disaster). I also tried to check the HTTP-only settings (which I’ve never modified), but that didn’t help either.

Is anyone else experiencing the same issue?

Seriously - it could be as easy as to just click "view certificate" so it opens up in Windows's standard certificate window where I can easily import it to my cert store, but someone decided it requires a bunch of useless and forgettable tasks so that FF recognizes it.

Ich habe über die Sicherheitssoftware "Trend Micro Security" eingestellt, dass keine heiklen Daten wie Kreditkartennummer, Debitnummer, Kontonummer etc den PC verlassen, ohne dass ich zustimme. Nun bekomme ich, wenn ich Mozilla Firefox öffne, ständig die Warnung von Trend Micro, dass die Sicherheitssoftware verhindert hat, das Mozilla eine von den gepeicherten Nummern übertragen wollte. "Die Funktion zum Schutz vor Datendiebstählen hat verhindert, dass geschütze Daten den Computer verlassen." Angegeben ist das Programm "Firefox.exe". Was passiert da bei Firefox im Hintergrund?

Hi, I recently visited what I thought was a valid website only to get bombarded with ransomware popups. They state that my McAfee account has expired, an account that I never had, and they insist that I click their link to repair it. It doesn't appear to be a hack or that it is currently mining any info from my account. Obviously, I know better than to click on the link ( one of which is: d3venj8hubcc73ch6bp0.texonnerro.co.in TROJAN VIRUS FOUND Click here to secure your data. There are 4 different messages but all have the same URL address). It's really just annoying at this point. Also, it is specific to my Firefox browser. I have no issues when I use MS Edge. I looked to see if I could uninstall Firefox but did not find any way to do that. I know I would lose all my settings, etc doing that, but if that's the only solution, then so be it. Any assistance you can provide will be greatly appreciated.

Thank you.

Hi,

Since last week I am unable to properly use some websites that are failing due to CORS requests, but they were working before. Some examples are es.webuy.com or a local Jellyfin instance. After trying to enable/disable some settings that I thought could be related to the problem, like security levels, I ended up creating a new profile. In this new profile everything works, but as soon as I synchronize my Mozilla account, then these websites start failing again with CORS requests errors.

Any idea about what setting might it be the one causing problems? Or any idea about how can I debug/troubleshoot it myself?

Thanks!

When creating a password on Linux Desktop version 144 it shows the password text instead of hiding or at least provding a option to hide when typing out the password.

Attempting to follow any number of Ubuntu 24 HOWTOs to connect the Firefox I installed from the ZorinOS App Store to the smart card reader and they are all failing miserably so far.

I am trying to use...

Module Name: OpenSC PKCS#11 Module Moduel filename: /usr/lib/x86_64-linux-gnu/opensc-pkcs11.so

I've tried a few other pkcs11.so's on other paths and FireFox just immediately crashes. This one it at least says it can't add it. The module is owned by root and has 644 permissions so I think it should be readable. Brave Browser is working well with cert auth via CAC and I already have the machine fully set up with logging in via CAC, locking screen automatically when CAC is removed, etc etc so I know that at a base level the CAC is working well. Just can't seem to find the proper link glue.

This is NOT the snap version of Firefox either, I am pretty sure. sudo snap firefox commands say firefox isn't installed.

I have two bank accounts. Both have been hacked and both banks traced it back to digital on line banking. they both claim that somehow hackers are getting to my personal info thru my computer. I do not use the phone of banking...and Firefox is and has been for a long time my default browser. Can hackers get my info from Firefox?

H&HNY2U&2U I'll appreciate your help! Please clarify if the alert containing a Firefox logo (pictured in the upper right corner of the image I attached), which flashed repeatedly while viewing the Apple page, is actually from Firefox or is a fake. thanks, HJK

I was googling something related to my game and i clicked on a Reddit search result, which i made sure is the official Reddit website not some shady one, then an empty .htm file from moz-safe-about resource got downloaded randomly. I didn't open it, i uploaded it to VirusTotal which came out safe and then i instantly deleted it and ran a virus scan with Windows Security which also came out clean. i tried to recreate this by opening the same website again both on Firefox and other browsers like Zen(Firefox based) and Chrome but nothing happened.

is this a harmless bug or should i worry that it could be a virus that didnt get detected?

I'm sick of having to turn off ai features in every freaking thing, if the product was any good you wouldn't have to push it so hard!

This is bad for my data security and privacy. Bad for the environment. Spreads falsehoods. And promotes plagiarism.

I'm already starting to look around for other browsers so I can switch over and delete this account if you don't stop this garbage.
