Firefox Community Forum

I can no longer use my camera on firefox, firefox displayed some message about camera when we were trying to chat, but I missed it, I have granted relevant permissions on the site, that we use reularly. The camera icon on the address bar appears red, and I noticed that in Windows security, it lists firefox access requests, but shows no way to grant these requests.

I am not tech minded so please if anyone could keep it simple, I would appreciate it.

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”?

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?

Hello,

i am following instructions from here:

https://support.mozilla.org/en-US/kb/automatically-fill-your-address-web-forms#w_turn-address-autofill-on-or-off

but i don't see option to enable autofill on desktop. On mobile, autofill only shows USA ans Canada. Why Chrome allow me to use address autofill and Firefox not?

Hi,

Just the other day I started getting these popups from "anti virus service" that keeps popping up on my screen. I do not nor never did have McAfee on my system. I did a deep search, and there is no program on my computer, nor in my startups, nor in my popups allowed relating to this. It is only a problem with Firefox. Any solutions?

Thank you, John

Switching to Protected Browser... COULDN'T LOAD XPCOM.!! it stopped a month ago and yet to get an answer , from you guys. It seems no one want to answer or try to find the error issue. Uninstall firefox and reinstall!!! No by doing that you will lose all of your data thats attached to firefox anywhere from you bookmark to user names and so on, Thas not a good solution AT ALL!!

Hi! After a routine update today to Mozilla Firefox 127.0 for Linux Mint, Firefox is asking for my master password before letting me continue. Sync does not appear to be enabled.

I'd really rather it didn't do this, because my password manager is now always open and accessible. Previously, the master password request was only triggered when I came on a site that needed a password.

Anything I can do to fix this?

Thanks for any pointers!

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?

OK - I must be missing something. On my previous browser, Opera, if I wanted to see details of my passwords then I needed to put in the computer password, so keeping them quite secure. However, Firefox seems to let anyone using the browser to access the full details of all my passwords, even offering to copy them! This has to be the most insecure approach possible - surely this can't be correct, can it?

Dear FireFox, I am writing this E-mail to address a critical issue. So i wanted to set up a password for my firefox browser so that only I can access it. i set a primary password, and it asks me to enter the password when i open my browser. However, when the message appears asking me to enter the password, you can just click "cancel" option or press 'x' it ignores the password and lets me in the browser, essentially rendering the purpose of the password useless. thus anyone can access my browser. i request you to fix this problem.

OK, I have Firefox (Windows 10 AMD64, desktop) configured to delete history when I close it.

So, I see that regular webiste cookies are deleted.

But are the HSTS website "super cookies" deleted?

https://ipleak.com/articles/what-is-hsts-super-cookies What are HSTS Super cookies and why are they dangerous?

thanx.

One of the add-in permissions is "Access your data for sites in the “named” domain". I looked at that and thought, "That certainly cannot include passwords"; BUT the explanation for this permission is: "The extension could read the content of web pages you visit in the specified domain, as well as data you enter into those web pages, such as usernames and passwords. "

I was stunned.

That means that addins that get this permission have access to my banking/medical/etc. usernames & passwords. This is not acceptable. Can a permission be developed that would be: "Access your data for sites in the “named” domain" (except usernames/passwords).

The permission "Access your data for all websites" is significantly worse in that it applies to all sites.

When I access a location-aware website, I'm asked if I'll allow it to use my location. My problem is that the pop-up window won't allow me to do anything. I can't block, allow, close the window — nothing. Is there a setting I'm missing somewhere?

I have a Yahoo email account and Firefox has the saved password for it. I've changed the password for my Yahoo email account recently. When Firefox prompted me if I want to update the saved password I must have chosen "NO", I don't remember. I stayed logged in the Yahoo email account for a few days after I've changed the password. I've logged out of the Yahoo account. Now I can't log back in because I don't remember the new password I've created.

I'm wondering if Firefox has the new Yahoo email account password saved somewhere in its cache.

OS: Windows 10. Firefox: 127.0.2 (64-bit).

When using Firefox (latest) and attempting to login into a website I get an error (see attached image) generated by the host's server's firewall. It appears it thinks I'm a bot. When I use Firefox's privacy mode I don't get this error. I would prefer not to use privacy mode. I contacted the administrator of the website I'm attempting to access and he couldn't offer any help.

When I use Google Chrome browser I don't encounter the above problem. This leads me to believe it's not an issue with my Avast Anti-Tracking and Antivirus settings.

Any help would be appreciated.

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.

Are Firefox extensions sandboxed from the rest of the operating system? Suppose I have installed a malicious extension/add-on on my system. Would it be possible for the extension to access and tamper with my operating system? I do not care if it tampers with the browser tabs or data inside the browser as long as it does not have a way to tamper with my OS. Using MacOS Sonoma

Hi, I would like to know which version of Mozilla used this setting of network.trr.excluded-domains: 'sbl-xbl[.]spamhaus[.]org, localhost.that.never.exists'. The default is 'undefined' as I checked in 127.0.1 and the older 124. I also contacted support of extensions that I used, no evidence of both excluded domains. Can anyone help me? Thanks a lot \!o!/
