Firefox 技術支援討論區

M2 MacBook Air running macOS Ventura. When I open a website which wants access to my camera I am asked if I want to allow this. I say "Allow", and the light next to the builtin webcam turns green, but I see nothing in the camera sub-window on the webpage which was granted access. No error message, just no camera video is shown by the webpage. In the menu bar is a camera icon which I can click on and confirms I have "Allowed" camera access. Setting / Privacy / Permissions / Autoplay is set to Block Audio. I have verified the camera works with other apps (Photo Booth). How can I diagnose this?

I am currently experiencing a technical issue with the Firefox browser that is impacting our workflow. After accessing a specific URL, we encounter a problematic page that we're unable to bypass. This is reminiscent of a past issue that was resolved by modifying certain configurations in Firefox's about:config page. Unfortunately, the previous fix is not effective this time. I have attached the error page with this ticket.

The settings we've adjusted are as follows: - security.insecure_field_warning.contextual.enabled = false - security.certerrors.permanentOverride = false - network.stricttransportsecurity.preloadlist = false - security.enterprise_roots.enabled = true

Can anyone tell how I can bypass this page?

Mod - please delete. I couldn't find a way to delete my question so I edited it. I had an issue but I think it's due to my Firefox being Enterprise managed. I tested the same thing on my personal laptop with Firefox and no issue.

Thanks!

I am an 84-year-old newbie! I have enabled 2 FA. But... when I click on Firefox in the taskbar F/fox opens and I can access all the bookmarks in the bookmark bar without any more security.

When does the 2FA come into this?

I want to visit a unsecured web site (camping site). I notice these mom and pop websites are unsecured. How do I visit it. I'm a big boy and dint like to be told where i can visit. However, I don't mind a warning.

We have enabled the "Prevent changing proxy settings" policy from the Group Policy Management Console. However, we've encountered an issue where Firefox browser overrides this policy. It has come to our attention that Firefox is the only browser that allows users to change the default Windows proxy settings directly from the browser itself.

To address this, we want to prevent users from changing proxy settings via Firefox browser as well. Could you please provide guidance on how to disable this feature?

I have moved to another password manager, and would like to completely remove my saved logins from my Firefox account and stop using the auto-fill, auto-suggest feature. However, no matter how many times I delete my passwords and Sync, they keep appearing in my Android Firefox app. I have cleared the app Storage and Cache, I have reinstalled it from scratch, but no matter what I do they reappear. My (also Synced) PC on which I deleted the passwords has not shown it again since I deleted them there.

I just want to completely delete all my logins in my Firefox account, permanently and across all my devices. How can I do this?

I have enabled privacy.resistFingerprinting in Firefox. I have also set my default zoom level to 133%

When I open a website (e.g. https://github.com/), it is zoomed to 133% as expected. If I then navigate to a page on that website (e.g. https://github.com/pricing) using the menu at the top of the page, then the new page is still zoomed to 133%. So far, so good.

However, on the new page (https://github.com/pricing) if I increase the zoom over 133%, then navigate back to the original page (https://github.com/) using the menu at the top of the page, then my zoom level is reset to 100%.

Is this expected behaviour? I would have thought that the zoom level would be reset to 133%, not 100%.

I found this, which seems somewhat related: https://bugzilla.mozilla.org/show_bug.cgi?id=1609880

In some recent update firefox privacy and security settings changed from saved logins to saved passwords. I find this much less useful. Can i change back to saved logins?

Hi,

I'm developing web app. I created and set up ssl auth for localhost with self signed cert.

When I hit my endpoint with firefox I see:

Secure Connection Failed

An error occurred during a connection to localhost:8081. SSL peer cannot verify your certificate.

Error code: SSL_ERROR_BAD_CERT_ALERT

   The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
   Please contact the website owners to inform them of this problem.

How to disable security in FF so I can test my endpoint?

I'm using the current Firefox-ESR for Linux x86_64. Under Settings > Privacy and Security > Cookies and Site Data > Manage Exceptions, I blocked http:174.138.51.92 and https:174.138.51.92 several weeks ago. But Manage Data shows 10 cookies last used 45 minutes ago, and Remove Selection for these cookies fails (incidentally retaining the "last used" value), even when repeated multiple times as fast as I can mouse the select, then Remove Selection, then Save Changes then Manage Data .

How can I delete these cookies and site data? And why does it fail for this site and this site only? And how can I block them permanently, short of black-holing that site in /etc/hosts?

Hi,

I've been using Firefox on my laptop and my phones for years. I have a concern about my saved passwords in Firefox. If I need to lookup a password, I go settings, saved logins, put in my pin# and search and copy my password. Many times; however, when I get to the enter password on a website, Firefox comes up above my keypad and will let me just hit the down button to pick my credentials and automatically fills in my credentials without asking for my pin! It will also come up above keyboard to unlock Firefox? Please help me to clear this mess up. I want to have to put in a pin for my passwords. Anyone could get into my websites if my phone were taken, etc. I know I un-installed the app for passwords from Firefox when it was no longer available, sorry can't remember name of this app. I hope there is an easy way to make this happen. The only way I want to look for a password is with a pin #. It's a pain but I am OK with this.
