Firefox Community Forum

I thought at first that the Master Password was for that, it seems however its purpose is only to protect access to the saved sites passwords. I set it up and it did in fact ask me for a password at startup but with just 2 tries to close the window, the prompt went away and did not prevent me to use Firefox further. It eventually appeared again but the result was the same. How can i prevent unathorized people using Firefox right at startup?

As we have observed on domain - "prod.detectportal.prod.cloudops.mozgcp.net" generating 1.5 crores of request on port 53(DNS) and action is redirect here i wanted to know the services why these traffic generating within one minutes, what will the reason? what will be the counter measure?

Hello All ,

Hope someone can help me on this. I am trying to access directly a device from Browser with an IP address. https://192.168.1.1 But i get the error : "Warning: Potential Security Risk Ahead"

Usually get the option of adnaced to proceed further. The Version is 130.0 (64-bit) and even set the about:config, security.dialog_enable_delay to minimum.

I have added the self signned certificate of the deivice to Firefox , but that is not helping, since i am accessing it with IP address and not FQDN. I cannot add it as exception in the exception list , since that setting also ask for DNS name.

Ip address access exception is no more available in this version , how can i proceed further and not downagrade to lower verion to support access via IP .

Regards, Zanoob

What should be my response to these messages? Dismiss closes the particular message, but it is immediately replaced with another similar one. I have no idea what the xxxx.mergenetworkprotocol is or how to use it. It is real or a phishing scam? Is it safe to simply tell Firefox to hide it?

I recently added an ADDON that function to, OPEN A LINK IN A NEW TAB.

I saw something about that the Addon wasn't monitored for security.

This lead me to ask this question:

DO ADDONS SEND INFORMATION TO OTHER ENTITIES BESIDES FIREFOX, FOR EXAMPLE DO THEY SEND INFO TO THE DEVELOPERS OF ADDONS?

Thanks for your help in advance, Kavin King

I found a potential flaw that can allow someone to gather all passwords saved by a user. It's pretty simple to explain, but also to exploit, so I don't want to do it publicly. Is there some specific team member that I should contact directly?

I don't want to use passkeys, and it seems that every site is checking browser support and wasting my time with passkey prompts before allowing me to log in with a password. How do I disable passkey support in Firefox?

Cannot delete cookies nor cache due to a grayish button. First it works fine, after a few hours, buttons are gray.

Also sync seems not to work anymore when this happens.

One of the typical configuration in linux is to turn off the user namespaces and/or network namespaces. This is because most of the exploits in linux have been related to namespaces vulnerabilities.

If there is a Firefox ver 127.0.2, running on Linux in which the user namespace is turned off then the following is observed in the Troubleshooting information, i.e. about:support Seccomp-BPF (System Call Filtering) true Seccomp Thread Synchronisation true User Namespaces for privileged processes true User Namespaces false Content Process Sandboxing true Media Plugin Sandboxing true

So how come with the username turned off, the content process and media plugin is still sandboxed? Also is having user namespace turned off, as given above, a security risk?

However if the network namespace is turned off, i.e. max_net_namespaces is set to zero, then it renders the browser unusable. Nothing works. Why is that?

Is there some documentation somewhere where these namespaces and their impact is explained in detail?

For System Administrative reasons, I want to disable automatic Firefox updates. Firefox can ask me if I want to install an update, but I get to choose whether or not to update.

Problem: Persistent 150 KB of Cached Web Content For several years, I have gone to “Settings” / “Privacy & Security” / “Cookies and Site Data,” clicked the Clear Data…” button, checked both “Cookies and Site Data,” and “Cached Web Content,” and clicked “Clear”, and consistently gotten BOTH “Cookies and Site Data,” and “Cached Web Content” down to “0” zero. Recently, I have been unable to “Cached Web Content” to go below “150 KB of disk space.”

         I have NOTHING listed in “Manage Cookies and Site Data” or “Exceptions -- Cookies and Site Data.”
         I have tried reinstalling, but the problem has persisted.
         On the assumption that this is malware problem, I have continued to use Mozzella VPN, but stopped using the program for browsing, etc.  Should I stop using it altogether until the problem is fixed?
         Can you tell me how to get rid of the last “150 KB” of “Cached Web Content”?

Hello,

My password saved are deleted every time I close FF. It used to be manageable because Google and other sites didn't require me to fill my passwords (cookies did the trick I suppose) but now I also loose access to gmail and Youtube every time I close FF. It's annoying to have to use 2FA every damn time. And keeping the passwords available.

I've tried every answer I found by looking around :

- tried to start in safe mode - disable hardware acceleration - I have no extensions

FF saves the passwords correctly (at least they appear in the saved password tab) but they are erased every time I restart FF. The cookies aren't automatically deleted (FF remembers my browsing history) but I need to relog into Google.

I getting frustrated.

How do I delete, remove, or otherwise disable that garbage "review checker" from the latest firefox update. It's useless, un-needed thing that I don't trust.

option to OPT out REMOVE/DELETE or completely DISABLE!

So Mozilla supports privacy rights- and I've supported Mozilla for that reason- but they want Whatsapp to be censored for "misinformation" ? How does that go together? Whatsapp was supposed to be encrypted and not even Whatsapp was supposed to know the content of messages. How would they know about misinformation? And how do they get to decide what's misinformation now?

Just for info this site works fine on other browsers on same machine, and on other machines. It is a Firefox issue.

Running version 127.0.1 on Linux.
