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?

Randomly after certain updates, the browser history gets randomly erased. The cookies are not deleted, so my sign in information is retained across my usual website (no issue here).

I wanted to report this as it happened twice around the past two weeks and it was inconvenient.

Im using Playwright with JS and when Im running ny test on FireFox i get a PopUp message to select the screen i want to screencast, even when im choosing screen and pressing "Share" its happened in the next test and not recording my tests. its happened only in FF. How im removed this PopUP ?Thanks. Using also Linux Ubuntu.

Hello Mozilla, When using Firefox I always have Enhanced Tracking Protection turned on - Custom, all four categories are checked, no exceptions are identified. Yet when I look at the Process Manager I consistently find third-parties (defined by me as NOT my OS, my browser, or any website I have visited during this session). As I write this I have just killed the following 4 processes, which I think Firefox should have caught. And in a few minutes when my active window is another application or when I take some browser tab to full-screen mode, these processes I thought I killed will reactivate. The current sample:

kampyle.com setpay.com signifyd.com trustarc.com

You may identify these as innocuous, but they are the very definition of third-party sites. Anything that calls itself TRUST is the first thing I'm going to question. Its exhausting having to police this constantly. What good is ETP if I have to supplement with my own time and energy, diverting me from my primary tasks?

Steps taken: Before submitting this I took a moment to check all the sites I have open or have had open on this device in this browser session. Clicking on the shield near the web address field, I have confirmed EPT is ON for each of them and I can see that many trackers, etc., are apparently being blocked. I also re-checked the related Firefox settings to ensure it remains as I selected.

Info: I work in remote locations, and carry my own hotspot with me. Its a cellular hotspot and I can have many devices as well as many tasks on any single device sharing the bandwidth. I started looking into this because these extra processes interfere with my use of my own devices and the bandwidth that I need and PAY FOR.

Thank you for your help. -LLD

For years we have been able to login to two different websites running on different ports on the same host with our Firefox browser (The last working version was 102.14.0-3.el7_9) our RHEL 7.x system. When I accessed the different sites, there was two Authentication Decisions, one sending one cert (We will call it CertA) to the system and the other listing sending a different cert (We will call that CertB) to the system, same hostname though.

I updated the Firefox browser to 115.7.0-1.el7_9 and ever since, when I navigate to the first website, it remembers the first Authentication Decision to send CertA to the system and works as intended. Then, I try to navigate to the second site and I never get prompted to pick a cert for the second site (CertB is what it should prompt for) and the connection attempt fails with a "Secure Connection Failed, Error code: SSL_ERROR_UNKNOWN_CA_ALERT" message.

If I go and delete the Authentication Decision for CertA, then go to the CertB site, I get prompted for the cert decision and I am able to login just fine. But, then if I try to go to the CertA site, I get the same error listed above.

I can use a band aid to check the "History > Always use private browsing mode" checkbox (Which never remembers the Auth. Decision) option in Firefox, then have to remember to close the browser each time I want to navigate from one site to the next. But I have never had to do that in the past and wondering if this is a new bug or if it is somehow considered a "Security Feature" or something.

I searched around the net a bit and couldn't find a way to manually add an Authentication Decision myself. Is that possible somehow with a config file edit on our Linux system somewhere?

Thanks kindly ahead of time for any consideration to my issue.

I have a local server where I host several apps (URLs such as http://192.168.0.101/). I've noticed that Firefox will not offer to autocomplete text boxes and forms on local pages.

I have the "Firefox will Remember history" option enabled, and autofill works elsewhere as expected.

I have tried using autofill for credit cards. The pop up to enter a password pops up and I fill that in. The credit card options are there and I click on the one I want and nothing fills in. I went to settings to turn off the request for authentication, unticked the box, and see no where to save that. When I refresh the screen, the box is once again ticked.

Здравствуйте. К своему стыду не могу разобраться. Поставил опции, во вкладке безопасность, удалять Куки и Историю по выходу из Firefox. При этом история сохраняется, при последующем запуске браузера. Так же при следующем запуске браузера, при авторизации на сайтах, автоматически заполняется поле "логин", "телефон". Как сделать что бы не заполнялся и была очищена история? Спасибо.

Currently, there appears to be only one option to tell Firefox to open a given site in a specific container; that is, from the URL bar, to the right.

Would it make sense to have this configuration option presented in "edit bookmark" and/or in a right-click pulldown menu "Always open in this container"?

I just installed FireFox but keep getting Chrome browser. How do I set FireFox as my default browser? My bookmark tab icons keep changing - how to change them back permanently ?

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

I use OnlyKey usb key as FIDO2 MFA with most of my accounts. On Firefox 123.0 on MacOS Sonoma 14.2.1 (23C71) however, I get presented with multiple pop ups to touch my usb key but the key expects only one input/touch and it fails when I touch it the second time. This was not the workflow that I used to use before and it still works fine on MacOS ventura with Firefox + protonmail.
