Firefox 125.0.1 update breaks all self signed certificates

After the latest auto update I can no longer access any of my management screens on my private network with self signed certificates. This is a real problem. I have attached a couple error screen grabs, but ALL of themn are the same. The information link says there is no workaround!

So how do I recover access? Chrome works just fine ... so it is def. a Firefox problem.

bsky.app cookie continues to be loaded on computer even after I continually delete it, privacy set to strict and blocked under "managed exceptions, why is it being reloaded when I don't access the site. None of the sites I access are linked to it, only visited once and if this alternative to x continues to set cookies, how can I permanently block it, thought the exceptions list was supposed to keep blocking it. So far it's come back three times, I'll screenshot it next time and attach.

Firefox was working well on HTTP websites until a few days ago, but now HTTPS-Only Mode seems to be permanent. Despite changing settings to 'Don’t enable HTTPS-Only Mode', when HTTP sites are selected I get the same message as for 'HTTPS-Only Mode'. Also, if I select 'Enable HTTPS-Only Mode in all windows' and add exceptions, I get the same result.

Hi,

I know how to turn on OS authentication to reveal passwords in about:config (signon.management.page.os-auth.enabled = true) But is there any way to turn this on in registry?

I cannot find a way to add websites to the location permissions in Firefox Windows PC. I can easily get to the "Location Permissions settings " but there is no way to add, only remove. When I display the access icon in the URL address bar, it shows " you have granted the website additional permissions" , but the site does not display in the FF Settings-Location Box, and the target website does allow me access based on location. Is there another area where location is restricted? would appreciate some help, thx.

When I try to go to my webmail I sometimes am presented with a Deceptive Site Ahead warning.

I am quite happy that although the SSL might not be current that the website is safe for me to go there. How do I stop this annoying feature from activating?

Is there a security setting that allows me to show all my passwords rather than having to toggle them on each time?

I am a recluse. There's never anyone looking over my shoulder. I just don't want to have to mess with it anymore.

If there isn't, could some kind developer please make an add-on?

I am using two computers: an iMac (late 2009) running 10.13.6 (High Sierra) and a Macbook Pro (13-inch, 2012) running 10.15.7 (Catalina).

Thank you!

I have a HUGE problem with Firefox memory usage. Some open instances of firefox are taking anywhere from 600mb to 2.8gb of memory. Since firefox opens MANY instances even with only ONE active window, this very quickly uses all available memory (4gb) causing a full laptop crash.

More concerning is that CLOSING the worst instance of memory usage STILL leaves the single open page/tab open, so what exactly was the memory eating instance actually doing ???

I have included a screengrab of the many remaining instances of firefox in windows task manager AFTER closing the main culprit.

I have also included a screengrab of all the adblockers I use which I believed would limit unnecessary memory usage, but does not seem to be effective.

Many Thanks

I am using Firefox for windows on my laptop and I have this issue where it stopped filling in my credit card information. I tried to follow the steps of turning it on/off in settings, except no "Forms" or "autofill" appear anywhere in my settings, nor privacy & security. Going into config, it appears that form and autofill for credit cards are both switched on and available. My browser is updated and everything else seems in order. How do I fix this?

The camera won't turn on in the Firefox browser for Google Meet or Zoom. It says it can't find the camera or that it's turned off. I have checked my Windows 11 settings and desktop apps have access to the camera. I have also checked the settings for each of the sites and use of the camera and microphone are allowed. Autoplay is enabled too. The camera works fine in other apps and in other browsers.

I'm using 107.0.1 vers. At this link it states: https://support.mozilla.org/en-US/kb/view-pdf-files-firefox-or-choose-another-viewer#w_use-a-different-pdf-viewer-for-downloaded-pdf-files

Disable the built-in PDF viewer and use another viewer

You can also set a different third-party PDF viewer to handle PDF files, instead of Firefox’s built-in PDF viewer. To switch from using the built-in PDF viewer to another viewer: 1. Click the menu button and select . 2. In the panel, go down to the Applications section. (SO WHERE IN THE HELL IS THIS SECTION???) YOU CAN'T DO I never selected Mozilla to open any pdf and there's no where to opt out or change based on what all the troubleshooting tips say... All these tips must be located on a much older version of Firefox cause they ain't in my version OR they are hid under some dubious section... Pretty frustrating....when you want to use Adobe and can't cause I'm locked in under Firefox....don't know how that has happened unless it was done automatically under one of the many current upgrades that have been coming down over the last month.

I am a UK user and have just installed and started to use Firefox on a brand new Linux Mint installation. As I am transferring from a Windows/Chrome environment, there is a lot of setting up to do. Firefox transferred most of the chrome info for me, and so I was able to get up and running with bookmarks and logins quite quickly. However, there is one problem that I can't seem to resolve.

I have been able to set up my credit card details, and these are prompted when needed, BUT, Firefox will not remember my name, email, phone or address. Thus for every form that I have to fill, I have to enter these details, again and again (and again).

I have looked at settings and see that the 'Autofill Address' option is not present (see attachment).

I have followed and implemented the fix proposed elsewhere, to update/add GB as an address format. This has not made a difference.

Can anyone please help.

Mark

Popups for Smithsonian magazine keep appearing, sometimes 2 at a time, despite having popups blocked. I need them to stop. They are annoying and cover up content of web pages.

I'm trying to connect to my Schneider XWPro Gateway for access to my solar inverter, and security policy on Firefox no longer't allows access. I can access using Safari by explicitly allowing access. Error from Firefox is as follows:

Secure Connection Failed

An error occurred during a connection to 192.168.1.120. You are attempting to import a cert with the same issuer/serial as an existing cert, but that is not the same cert.

Error code: SEC_ERROR_REUSED_ISSUER_AND_SERIAL

   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

Your error message states there is a problem with a certificate conflict, however there is no apparent way to tell which certificate is causing the conflict, so there is nothing I can do about it. This is a new problem, I have been able to access this device in the past.

Any suggestions?

I have 2-Step verification on Gmail. When I go to log in I get this: Insert your security Key into the USB. I cancel out of it and get this: Your phone can’t locate your device. Move your phone closer to the device where you’re signing in, and then try again. I "Try another way" and I try to get a "one-time security code" and it forwards me to a website where the cycle begins again. If I try "Auto-recovery" it sends me to google. I can access Gmail on the same machine via Chrome, but would rather not. I can also get it on Firefox on my phone.

I did recently turn on two-step and it asked if I wanted a key, and I thought it might mean Google Authentication, I think it meant a USB key.

Any thoughts? I rather not give up Firefox.

I use FF 116 on windows 11. For months, I have had problems logging in to web sites. At first I thought the problem was with the web site, but I have come to the conclusion it is an FF problem. GlobeandMail.com, gem.cbc.ca and rbc.com for example ask for me to log in. I go through the steps giving my password and login name and the web site seems to accept these without complaint but it continues to want me to log in. I end up having to use Edge which works fine. Is there a solution?
