I have an issue with Firefox 127 not accepting a session cookie that I use for user authentication. I have an ASP.NET application with a login form that includes fields for login and password, and a submit button. When the button is clicked, an HTTPS/POST request is sent to the server. The server responds and sends back a session cookie named .Cookie.Name with the parameter httpOnly set to true.

When I check in Firefox's Developer Tools under the Network tab, I can see .Cookie.Name in the server response. However, in the Developer Tools under the Storage tab, .Cookie.Name is missing, which prevents the user from logging in. This problem does not occur in other browsers like Chrome or Edge, nor does it occur in Firefox version 126. The configurations for Firefox 126 and 127 are identical.

Could you please assist with this issue?

When going from Help on menu to check for updates receive the error message - Failed to check for updates.

Running on Windows 10 with NAV - problem is recent in origin but I can't be exact as it's not my regular PC.

So far I've manually updated Thunderbird from 115.11.1 to 115.11.2 (64bit)by downloading from Mozilla website, rebooted from cold several times, and applied the fix from Norton:" https://community.norton.com/en/forums/auto-update-norton-360-v2449067835-now-causes-security-exception-thunderbird " in case it was related. It appears to be unrelated because on my regular PC the NAV update occurred necessitating the fix to the security exception error but don't have the checking for updates error.

thanks

I just noticed that I can no longer re-arrange tabs by using drag-n-drop or create bookmarks in my bookmarks bar using drag-n-drop. Is this a new "feature" in 127.0?

I had trouble updating my email accounts due to an issue with the profile update. The solution for me was to delete the 42 copies of the profile and basically start over. Now I need access to some of the folders where emails were locally stored. I know where on the computer fined the folders/files of the old emails. How do I import them into my current TB profile?

While using Thunderbird, it mysteriously stopped connecting to Yahoo Mail. This happens every few years and I think it's related to Oauth2 credentials.

I generated a new secure mail key and copied it into Thunderbird but that didn't work. So then I checked online, and one of the steps in the Thunderbird instructions is: "Select 'Server Settings' for mail account; Set incoming server 'Authentication Method' to 'Oauth2'; Click on 'OK' ". But Oauth2 isn't one of the options. The choices are normal password, encrypted password, Kerberos/GSSAPI, and NTLM.

I'm using POP. Tbird version 115.11.1.

When attempting to add a second email address to Thunderbird, I get the same error message every time. I have tried updating TB and restarting my computer, here are the steps I follow, please let me know if I should include any diagnostic logs/how to get them as well.

Please note that I already have an account set up that actively works, both sending and receiving gmail. Settings > Account Settings > Account Actions > Add Mail Account Enter my full name, and email address, but leave the password field blank according to other advice on this forum, although I have also tried with entering the address. Press Continue, receive the "Configuration found in Mozilla ISP database." message. Select IMAP > Done. See a google sign in page, with my email already filled in. Select Next. Then I get a Google 400 error page, reading: "400. That’s an error. The server cannot process the request because it is malformed. It should not be retried. That’s all we know." If I close that popup window, there is now a message in Thunderbird saying "Unable to log in at server. Probably wrong configuration, username or password."

Images with more details are attached below, note that this issue persists after both an update and a restart. Please ask any questions that can help you help me. Thanks in advance.

Currently, Firefox opens OBJ files as text. I want to send them to the Microsoft 3D Viewer which is the default application in Windows for these kinds of files. All I can do right now is right click on the file, save the file, then open with the 3D Viewer. I have gone to settings/General then down to applications and I can't add any files there. (Why not?) It doesn't matter if I choose to save or open files, the OBJ file still displays as text in Firefox. How do I get Firefox to send instead of display these files as text?

Hi,

I can't watch live stream on youtube. I see only black screen on loading circkle. Ads working fine but after them i see what i said before. When live is over then i can normally watch it. I can watch twitch normally. There is problem olny on yt. best chris

I have the strangest problem. If Firefox is closed and I do a speedtest in another browser, download a file, or do other internet activity I'm getting about 200-250Mbps d/l and 100Mbps upload. As soon as I open Firefox, whether I load a page or not, the upload speed stays the same, however the download speed drops to about 25-50 Mbps. This only happens on one PC, the upload isn't affected, and resolves itself as soon as Firefox is closed. Here's what I have done without any change in this behaviour;

• Rebooted
• ipconfig /release /renew /flushdns
• Removed and reinstalled the network adapter
• Enabled, disabled windows auto tuning and tested (slower disabled)
• Updated Windows
• Refreshed Firefox
• Uninstalled Firefox, deleted remaining folders from Appdata (Local, Low, Roaming) as well as the program file directories and "Mozilla" registry entries. Restarted and reinstalled. Issue immediately resumed when Firefox was open.

Also when connected to a VPN Firefox download speed increases to about 60Mbps and is consistent across other software. If I split tunnel another browser outside the VPN, it is still stuck at 60Mbps. If I close Firefox the speed increases.

This makes absolutely no sense to me, so I'm hoping someone can shed some light on this - but it does seem to be something Firefox is doing.

Thanks for any help anyone can provide.

Hello everyone! :)

I'm using Thunderbird for many years. Today I had to reinstall my Windows and obviously to set up my apps including Thunderbird. Unfortunately an error is popping up after I filled all of the required information. I restarted my PC. I reinstalled Thunderbird. I'm using the most popular email client in Bulgaria.

Nothing works so far. Screen shots are attached including the provided settings from my email client.

Thanks!

Hello!

I get this error often when I try to access various websites. This doesn't happen when I use Opera, so I assume the problem is not with the websites.

My OS: Windows 10. My Firefox version: 127.0 (64-bit).

Trying to use my old profile on a fresh install.

After trying a few things I ended up with an error that the profile couldn't be loaded or was inaccessible.

So I did the following:

1) started the profile manager 2) removed all profiles 3) created a new profile 4) changed the name of the folder in the file system 5) copied my old profile folder to the same spot with the same name that the profile manager gave it

When I started thunderbird, I was just expecting it to load with my old profile.

Instead, I got the Account Setup screen.

I don't want to setup my email account, as I'm worried it will start downloading all my emails, and store them in who knows what profile. I could not see a way to start Thunderbird without it successfully connecting to an email server in this setup process.

Any suggestions for just getting mozilla to start and load my old profile please?

Greetings support team. The problem is a bit complicated and I could't find anything similar to it on the net, so I'll try to explain in details what happened. One day after opening the browser I noticed that it didn't launch(there was no window). After opening it again I saw that all of my previously opened tabs were gone. After that I closed Firefox and went to check the task manager. I found that Firefox was still running after closing it. I couldn't wrap my head around it and killed the programm. Then I opened it again and got the same results: first launch: no Firefox window(nothing on the taskbar either), secound launch: one empty tab. After that I opened a new tab in Firefox through task manager and my screen "swiped right", I got access to Firefox window with all of my previous tabs, but all the other programms I had opened on the taskbar were gone. Somehow Firefox opens outside my screen on a "separate one" every first time I launch the app, and the only way to switch between "screens" is to open a new tab through task manager or launch a program that was previously active to switch back to previous "screen". It is also impossible to switch between opened windows on different "screens" using gestures on the touchpad or "Alt" + "Tab". I use a laptop and never even tried to attach/connect a second monitor. I don't have another monitor attached via bluetooth or any other means in device manager. I have the latest verion of windows 10 installed and updated. I have another PC, where I use the same Firefox with the same addons on the same Mozilla account, which has no such issues. I have tried renaming the file called "xulstore.json" to "xulstore.old" or deleting it entirely, this didn't resolve the issue.

Youtube audio is extremely slow, I reckon at 10%, but the video is fine and can be sped up or down. The problem persists even in troubleshooting mode, after cache clearing, hardware acceleration turned off, enabled DRM and widevine, driver updates, in private mode or not, logged in or not, firefox restarts, computer restarts.

But Youtube plays fine in Chrome and Edge.

I dont think I didnt anything drastically different, or updated win10 or firefox, or messed with anything. It was working fine a day ago.

Is there any way to reset something?

Thunderbird suddenly says "authentication failed" for my rocketmail email. Was working fine up til now. I can still log into the email directly via Yahoo. Any ideas on how to fix this.

v115.10.1 I made a mistake setting SMTP credentials, wrong protocol, and it just stays on Sending dialog. So I abort when I realize I made a mistake and come back to mail I was to send. - but 30-60s after I aborted comes an error message saying it timed out

So the cancel button does not really cancel the send attempt, it seems.

Not sure where to report bugs, so do it here. Thanks.

Fixed, see /questions/1450036 Solved 6/15/2024 problem of frozen screen

Apologies if I'm repeating a previous request - couldn't tell if it was submitted.

I'm running Windows 10. While changing the startup screen somehow an image I thought was deleted appeared and now is frozen, apparently on top of a Firefox window. I've rebooted, restarted and followed the Windows help suggestions with no success. Right now I don't know whether this is a Firefox or Windows problem. I updated Firefox today to the newest version before this happened.

Any help will be appreciated. I can open new Firefox windows.

P.B.
