Firefox Community Forum

I work in IT and unfortunately I am working on too many brand new and obscure devices, they have expired and self-signed certs and I can't just keep trusting them, even though thats not working. I need to be able to completely turn off all protections for SSL certs if I can.

I have 2 workstations and I use firefox as my primary web browser for both workstations. My office computer gets secure connection failed which is my main computer but I'm able to logon with my laptop computer without any issues. The site is internal which access our monitoring software for wireless. I'm able to access the site via other browsers, Chrome & Edge on my office computer without any issues. Not sure what else I can do to make this work on my office computer since this is the main computer I use. The following is what I get:

Secure Connection Failed

An error occurred during a connection to 172.20.251.12. 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

I recently migrated my Firefox profile from a windows 10 to a windows 11 computer. Everything seems to be working fine except saved payment methods.

My cc info appears when I go to type in card information on a website, but when I click on it and press enter or tab, it disappears. My saved payment methods in settings appears empty, and the add button doesn't do anything.

What can I do to fix this?

So, I use Fn + F7 which should stop or play the last active audio source.

Sometimes it works, sometimes it just refuses to work for one site at time, while the others work fine. So, for example, I have site x which plays audio, and site y which played audio some time ago, both windows open. Sometimes medias keys work as supposed, sometimes it doesn't work for site x for no apparent reason while it works for site y, or vice versa.

To get it to work, I have to spam it, move the tab around to the front (sometimes it works, it seems it gets priority, but it could be just coincidence) or completely close the tab and open another one with the same site. Whatever's causing this, it seems to be random, but it seems to be caused the most when having multiple tabs that can play audio, but not exclusively.

I just switched to Firefox and I don't really want to switch back, so it'd be great if any assistance is offered. On my last browser this wasn't the case.

This is what I've tried to solve the problem, but didn't work: - Go to about:preferences and turn off and then back on media.hardwaremediakeys.enabled - Open your Firefox settings (about:preferences); Uncheck Control media via keyboard, headset, or virtual interface. It is at the end of the page; Restart Firefox; Check that setting again

Additional information: - Here's the site that causes me trouble the most (this is a YouTube playlist loader for big playlists): https://youtube-playlist-randomizer.bitbucket.io/ - I use Windows 11

OS Version: Windows 11 Home, 23H2 Firefox Version: 127.0.2

I have several virtual desktops: Desktop 1, 2, 3 and 4. Case 1: Assume that there is at least one opening Firefox window in any virtual desktop. And, if I try to open a new window in Desktop x (x = 1, ..., 4), it will appears in Desktop x as expected. Case 2: Assume that there are currently no opening Firefox windows in any virtual desktop. And, if I try to open a new window in Desktop 2 or 3 or 4, it will only appears in Desktop 1.

When I move the cursor over the bookmarks bar the Tabs bar opens and closes causing the bookmarks to move up & down and prevent the cursor from using the bookmarks bar, How can I fix that?

Is there a functionality to view Tabs Side-by-Side, or Vertical yet? Or is there a plan for it; similar to the recent version of Edge Chromium? I have read several questions; and their work-around solutions of using a side bar or sing two windows and arranging them side-by-side. Neither functionality offers synchronized scrolling. I used Tile Tabs or We Tabs add-on in the past which was great.

I imported my bookmarks through an html backup but I dont see them on the bookmarks bar and when I sync my chrome browser data everything is all screwed up How can I import my chrome data minus bookmarks

I get this msg from FIrefox when I try to login from the webpage kp.org. I have no problem on Microsoft Edge.

"The page isn’t redirecting properly"

Also on NBCwashington.com/weather the video doesn't play on Firefox but does on Microsoft Edge. I contacted NBC Washington local station and they can find no problem on their web page.

Hi I have lost all my bookmarks. I bought a new device. On downloading Firefox the the bookmarks toolbar was Google's. Now Firefox on my other devices has the the Google bookmarks toolbar. Help please.

Updated my Win 11 laptop with latest changes and find the fonts on pages and on tabs is all messed up. I've tried Settings to choose larger size, set defaults to Arial and/or Arial Round .... does not help.

How do I either fix this, or undo this update, or is there a fix coming ASAP??

Bonjour, depuis quelque temps je n'arrive plus à me connecter sur mon interface du site https://www.leboncoin.fr/annonces/offres/provence_alpes_cote_d_azur cela fonctionne avec edge mais je préférerai rester avec Firefox. Le bon coin me dit que c'est un problème de configuration. pouvez vous m'aider ? avant cela marchait très bien. merci d'avance, V Paul

I see this is a known bug but this bookmark sidebar has suddenly started to appear on my desktop when ever I open Firefox and there seems to be no understandable method to turn it off although there are several arcane techniques that require me to go to weird places and change the names of files. No indication of what the unintended consequences of that might be. Is this something you can fix? Will the next update. This is really frustrating. Help please. So to be sure, I do not consider the challenge of getting into the pants of a program to fix a bug to be fun, exciting, interesting, etc. This is a tool and my browser is acting up. That is a pain in the butt not an adventure.

Hello, i want to know if i can use dark mode in the main web sites of mozilla, like support page or account page, becase it hurts my eyes when i want to switch from other sites where i at least can use some extension to fix it but all mozilla pages always bright white. What i have to do? Thanks

我已经打开了“在需要时显示触摸键盘”选项，但是经过我的测试，所有的软件、浏览器（Chrome、edge、Steam等等）都能够正常唤起触摸键盘，只有Firefox不行

I have turned on the "Show a touch keyboard when necessary" option, but in my tests, all software and browsers (Chrome, edge, Steam, etc.) are able to call up the touch keyboard properly, except Firefox
