For a few weeks, I've been unable to download Nightly updates via Help>About Nightly because Nightly thinks another instance is updating. I have found no solution or information on this issue. I never run more than one instance, though I usually have 50-60 windows open with many tabs each. Am I hitting a hard coded assumption that more than one instance is running if some number of windows and/or tabs is implying multiple instances? Nothing else seems to make sense so far... This issue just appeared one day; I recall nothing out of the ordinary. Was just trying to download the latest Nightly as I'd done for years and am now stuck with this issue preventing access to updates.

Files previously downloaded by earlier versions of Firefox as .webp cannot be opened by 115.19.0esr. Firefox keeps asking what application to use, and I have selected Firefox. When I OK the selection, it opens a blank screen with the same question (what application to use). This goes on forever, opening a new blank tab again and again, each with the same question about what application to use. My old Mac operating system 10.13.6 retains its original version of Preview installed, and of course, that version of Preview does not know how to open .webp files.

For many years now I've had Firefox clear

  • browsing & download history
  • temporary cached files and pages
  • saved form info

but not

  • cookies and site date
  • site settings

This worked flawlessly until Firefox updated to version 136, at which point all cookies were deleted and I was signed out of every account on every website.

Looking at the settings page, the option to delete cookies and site data when Firefox is closed is now enabled. I don't remember what this setting used to look like, but I did not change it recently.

Unchecking the box seems to work, but I shouldn't suddenly have to do this, and the "damage" is done.

Why did the update to version 136 sign me out of every website, and how do I protect myself against this happening again?

I want to get back ability to use websites without using passwords every time I log in. I inadvertently deleted all cookies and data from websites I use.

I'm having this weird issue where youtube videos will play fine as long as I don't seek the video. If I do seek a couple of times, the image will freeze but the audio continues. The subtitles also continue if enabled. Firefox Release 134.0.1--January 14, 2025 Fresh install from Flatpak. No addons installed.I have tried both on and off hardware acceleration but the issue still persists even in troubleshoot mode.But no problem with other firefox based browsers like mullvad,librewolf,zen.

i asked this already but no answer. I have two recovery keys, how can i check which is the one set for my preferred installation of Firefox. One was for my en-CA install, the other for an en-US install made a week later due to an update glitch. I had to use my en-CA recovery key to recover my settings to the en-US install, which then made a new recovery key.

I want to get rid of the spurious en-US install. -en-CA is in it's original location c:\program files\mozilla firefox

-en-US is in "C:\Users\%username%\AppData\Local\Mozilla Firefox\firefox.exe" the directory trees appear the same except en-CA has a locale.ini file that the other does not.

Does the original recovery key STILL apply to the -en-CA install or has the -en-US install's key replaced it.

And can I delete the -en-US folder with consequences?

Firefox is not letting me access my Windows or Microsoft account. (using WIndows 11) The login popup is asking for School or Work email, which is not applicable to me. I input my usual login information and Microsoft pop-up says account does not exist. When I login to Windows, using a different desktop (Windows 10), I do not have login in issues.

What is the browser setting that needs to be updated.

Did Firefox lock me out of my emails? I can see them but when I click on them, they will not open. I was to verify my secondary email and have not as yet. We have had several screen chats and due to my lack of understanding, I still do not know what to do. I know nothing about computers and do not know all the basic terms used. I graduated from college 53 years ago. I hate feeling like I have no intelligence at the age of 76 but it may BE TRUE. Yawl have been very patient and kind and I do apologize for disturbing you again. Thanks in advance for any help you could give me.

I have built an HTTPS server using Apache/2.4.62 in a Linux environment using CentOS Stream release 9, but if you change the port number and access it, the behavior is different from Chrome/Edge, so please let me confirm this.

Client authentication is enabled when using port 443 or 44999 in /etc/httpd/conf.d/ssl.conf.

The server certificate has been imported to the client PC, and the client PC certificate has been imported to the server.

I attached index.html to /var/www/html/ on the server side and set it up so that test.html would open on port 44999 when the "Start" button on index.html was pressed. When I do this in Chrome or Edge, a certificate selection screen appears and when the client sends the certificate, the result is successful.

However, when I try this in Firefox, the certificate selection screen does not appear and the result is a failure. Why does the certificate selection screen not appear?

Also, when I capture the packets at this time with Wireshark, it appears that an empty Certificate packet is being sent in response to the Certificate Request from the server.

If you enter https://IP address:44999/test.html directly into the address bar, you will be able to access the page successfully.

And the contents of index.html are as follows: <title>connectTest</title> <meta charset="UTF-8"> <script> function connectTest() { var request = new XMLHttpRequest(); var testUrl = "https://192.168.137.149:44999/test.html"; request.open('POST',testUrl,true); request.send(); request.onreadystatechange = function(){ if(request.readyState == 4){ if(request.status == 200){ alert("Success"); } else { alert("Error"); } } } } </script>

コネクションテスト

<button type="button" onclick="connectTest()">開始</button>

test.html just displays "Hello World".
