I use Firefox Developer, on many sites, for no apparent reason, the error "Error establishing a secure connection" started popping up (error code: PR_CONNECT_RESET_ERROR. Even on YouTube, where everything was ok before, it's all crap now. HELP PLEASE

Hi, Can't get rid of the funtion "threads" in Thunderbird. What I want is to ignore any connections between original mail and answers to it. I would like just to have every new mail adressed to me as new unread mail. Not deleted, not visible or marked as "read". The funtion "ignore threads" don't seams to give me that option. Except for that, Thunderbird is great. Better that Outlook since it is able to sync it's caledar with google.

I have recently updated my Windows 10 machine to Windows 11. I went to Microsoft.com and clicked Sign In to log into my account but the page will act like you're hitting the TAB button on the keyboard over and over and also hitting enter. Since it tabs through the hyperlinks on the website and acts like I'm hitting ENTER it opens a new window/tab to https://www.microsoft.com/en-us/servicesagreement/. If you have pop up blockers on it will keep blocking the page while tabbing through all the hyperlinks on the page. I have recreated this issue in both the Firefox standard download version(Currently on 136.0 64 bit) and in the Microsoft Store windows app version of Firefox. I have tried clearing my cache/cookies and Private browsing as well to help keep some weird data sync from occurring. I checked my SSO settings in windows and don't have anything that would cause it to try and auto-login with that either. The "Allow Windows single sign-on for Microsoft, work, and school accounts" is not enabled. I noticed this ONLY happens when you try to login to Microsoft with the login.live.com link instead of the login.microsoftonline.com link. I tried recreating this on my phone on Firefox for Android and it does not happen. Chrome and Edge do not have the issue either. I did not have this issue on Windows 10. I have not tried uninstalling the browser since the Microsoft/Windows App version of Firefox had the issue and I had never downloaded/installed that version before. I did not log into my Mozilla account on that version either to try and help figure out if this was an account data problem. I tried to report this on the report a bug but the bot auto closed my bug report. If anyone could help I would appreciate it. Really don't want to switch over to another browser for such a small problem like this. I can't add any image since the page constantly opens a new window/changes. Thanks!

Somehow, my desktop started showing a beautiful scenic picture, that it changes several times per day. I can right click and get more information about the picture, but I find no way to turn this off. It not only is distracting, but often the lack of contrast make folders on my desktop hard to read.

How to use FireFox as incognito without sending my identification tracking information? I have read a bunch of information about privacy with Mozilla and am quite confused.

I would like instructions that are simple to understand and implement.

I have heard that when some airlines know that you are looking for tickets ... the ticket prices are increased when you go to their website over time and time again.

Thank you

Is there anyway to force actual mozilla pages to be displayed in a dark mode instead of the blinding white background that hurts my eyes to view ? Thanks, David

I am using light visual mode. Whenever I am viewing a dark image, e.g. a relatively dark photo in a newspaper article, this darkens the entire page, including the menu/bar area. This happens as the dark image is scrolled to become visible. Normal bright views are restored once the dark image is out of view. And similarly my youtube music page, which has a black background, is horribly black now. I a musing windows11. Thanks.

Since the last Firefox update I can login in my outlook email-program, but after login the screen remains blank. In my banking account I can do transfers, but if I want to download a receipt (what earlier always was function properly) the screen remains blank.

For the past several weeks I have been having issues where some parts of websites don't load like on Twitch and amazon, and YouTube videos are choppy and pause playback frequently. I have a 7800 X3D CPU, 32 GB of DDR5, and gigabit Ethernet so its not a problem with outdated hardware. I also reinstalled the newest drivers twice, updated my bios, updated Windows, and reset my router so I'm not really sure whats causing the problem. I tested twitch and youtube on Edge and the issues are kinda there but considerably better. I was having similar issues on youtube several months ago when I was using opera, so I switched to firefox and it seemed to fix the problem until now.

I switched to using Firefox about six weeks ago, from Chrome. At first, it all worked perfectly. Now, I have a 100% reproducable problem: YouTube "short" videos never play. It will display the video player in the proper aspect ratio, and displays the overlayed text from the video's thumbnail and other meta data, but the actual playing of the video fails with a message typically like:

An error occurred. Please try again later. (Playback ID: C8SVj-KCLVM2m_DW)

Windows 11, current patched. on serious Core I9 system with 32 GB of ram, fast video card, etc.

Regular YouTube videos display perfectly. Using Google Chrome browser works perfectly.

The help message talks about clearing cache, but I can't seem to find that. I can see how to delete site-specific cookies and data. I really don't want to clear all cookies for all sites.

Recently Firefox has been randomly crashing the past 3 weeks multiple times, Is anyone else having this odd issue ? I'll be watching a stream or youtube video and bam out of no where the Browser goes black for like 20 or 30 seconds then crashes. I sent in about 3 crash reports and wondering if the Firefox team is aware of this issue.

Hello there. Over the past few days iv had some problems while using twitch.tv . Im not able to use the chat because it says "failed to load module" .

At first i assumed this was twitch, so i tried chrome but its fine completely fine, there's no failed to load module error

I then deleted my cookies and cache but the error still persists. Its also fine when using the private/incognito mode.

Im on the latest version as well

Hello, I've got the french version of Thunderbird on my laptop. I want to have it now on my smartphone Android. But impossible to find the function "move to mobile" in the parameterss... Please help me !

We use Firefox ESR in our environment today, Is it possible to have a policy that would display "update required" message to end-users, or have it automatically update without users opening the browsers.

Although listed as one of the options for default language, the current version of Firefox, which is my default browser, does not accept Brazilian Portuguese as the default language. It only accepts the Portuguese version, from Portugal which, to me, who speak Brazilian Portuguese, with all due respect, is a pain in the butt. I have tried, dozens of times, to delete the Portuguese version and set the Brazilian version as the default language. It works until I shut down the computer. The next time I turn on the computer, to my eternal dismay, Firefox cancels my previous language setting and reverts itself to the damn Portuguese version, which I dislike to the extreme.So I am, hereby, taking the issue to you with high hopes that this abdomally be straightened out once and forever. Many heartfelt thanks and wishing you sucess. Damião

My facebook account keeps getting double logins and ip4 logins rather than ip6 addresses. I think my ex-employer has installed a certificate into firefox on my laptop. I know absolutely nothing about certificates and have never knowingly installed one into my firefox web browser. But after looking I seem to have a certificate, is this certificate something that is allowing someone else access to what I view on my browser or allowing access to my cookies? Would users normally have their own firefox user certificate installed that they are unable to remove with a year on the date? I have added 2 screenshots. Hopefully someone can help Best regards David
