Firefox Support Forum

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.

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?

Extension has permission "Access your data for sites in the abc.de domain".

The documentation says that such extension can read "data you enter into those web pages, such as usernames and passwords"

Can extension send such data away (for example to its developer)? What kind of permission is needed for that? Can you quote exact name of such permission/s from linked article so i can lookup that?

Greetings. I recently upgraded to Windows 11 and started using Firefox again. In order to be more secure and private I am reviewing all of my settings everywhere. I am concerned that the security certificates that are currently in my Firefox are safe, secure and current. I know the internet is worldwide and bad actors can from any country but when I see them from certain countries that does concern me. Is there a way to verify the certificates are good? Is there an harm in deleting certificates? Is there any suggestions of what countries, websites to stay away from concerning certificates? If the validity is expired should I delete it? I do not like to make assumptions. I try to make informed decisions. Thank you, bkh8611@gmail.com

Hello, i need help. If I create shortcut, and start firefox in another profile, like this:

"C:\Program Files (x86)\Mozilla Firefox\firefox.exe" -class FF2 --profile "C:\Users\mire\Desktop\TEST\Apps\Instagram" --no-remote instagram.com

And if i set in "user.js" --> user_pref("taskbar.grouping.useprofile", true);.

For some reason after firefox starts, or after second start, firefox icon on the taskbar turns into a private browsing icon!

I tried everything to prevent this, I tried to add:

user_pref("browser.privateWindowSeparation.enabled", false); user_pref("browser.privacySegmentation.windowSeparation.enabled", false);

Nothing works...

I checked million times that im not in private browsing, and i'm not.

Then, after some tests I found that if I remove the flag: "user_pref("taskbar.grouping.useprofile", true);" from 'user.js' and 'prefs.js', and start profile again, taskbar icon becomes normal firefox icon.

Is this a bug?

And what should i do if i want to have separate grouping for the PROFILE2, and i don't want to have that private browsing icon?

You can see in the picture what was happening...

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?

PC/WIN7 - I access my bank and get a login screen from them... when I enter my name and password I get a "FILE NOT FOUND" ... but it accesses just fine on my android phone or on my other laptop running WIN10... maybe a problem in firefox site permissions ?? Used to work up until about 4 mos ago....

Some sort of problem deleted saved passwords on my desktop passwords on devices are saved I can tried to sync them but nothing happends. Whenever the request to save a password it is not saved on desktop.

Hi, I have a lot (+1600) password stored in my profile and i would like to clean its and delete olds ones. So i look for an utility or an extension to mark only those i want to delete (or keep).

Can i make an export to csv file, open it with excel (or something else) delete these unused, save the new csv, delete all password in firefox, and import the new csv ? Have i to make an new synchronisation in all my pc,tabs,phones after deconnexion on its? Many thanks for help JP from France

I spoke to BT who proved that Firefox and not Edge was the problem and there is a need to know how to remove entries which appear under the Firefox through either Autofill or Autosave or finally Autopopulate. This need arises from a problem which has arisen under username entry and which cannot be permanently removed.

I need some advice on how to resolve this problem!
