Firefox Support Forum

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?

I have had an issue for months where streaming services like Netflix, Hulu, Max, and Amazon Prime will not work on Firefox. I am updated to the latest version, 127.0 (64-bit), and am able to successfully log in to these streaming services, but without fail get an error message when I attempt to stream a video. Netflix returns a F7531 error, Max returns an error code, and Prime Video says I cannot stream without the latest version of the browser even though I am up to date. I have restarted and updated Firefox multiple times, have toggled and uninstalled extensions and nothing has worked. The extensions I currently use are Auto Tab Discard, Google Analytics Opt-Out, Honey, Return Youtube Dislike, Search by Image, Shinigami Eyes, Sponsorblock for Youtube, UBlock Origin, To Google Translate, and Video DownloadHelper.

Until a few days ago, my Firefox would save all the tabs from the previous session. But now it does not, and I still have all the necessary settings enabled. I noticed that it will save the previous session IF I use the Firefox "EXIT" from the "File" menu. However if I use close the session using the upper right hand corner Windows close box (where the "X"), it does NOT save the tabs from the session. I also notice that when I close the Firefox window using the Windows close box, that Firefox (several) show still running under the Windows Task manager, but not when I use the "File:Exit". Running the current FIrefox version 127.0 (64-bit) under Windows 11.

Hi! I don't like the automatically updated extensions -feature, it seems to have been turned on nowadays, it has been maybe a year or two when you had control to update them by hand! I don't like this feature and it seems to now be in every browser that I use, Firefox, Opera, Brave, Vivaldi! Is there a way to turn this function off? Maybe a commandline function or an editable thing in a configuration file! Other browser developers should also think about this! I think Firefox has been a good browser to use, I used to use Opera but changed to Firefox quite accidentally when having to install things again!

Send is a free file sharing service launched by Mozilla under its Firefox Test Pilot project, which is mostly a bunch of experimental features for Firefox. While the majority of applications under the Test Pilot project are essentially plugins for the main Firefox browser, Send is a standalone service, that can be accessed via any browser. It works on a web interface and allows the user to easily upload any file to Mozilla’s servers and then download it to the other device with the help of a shareable link. What’s more is that Mozilla offers great privacy due to the encryption of the data being transmitted. Now that you know what Firefox Send is, let us discuss how to use it.

How do I enter Firefox SEND menu?

I have been trying to contact support about an issue regarding being able to change my account password to the page at https://support.mozilla.org/en-US/questions/new/mozilla-account/form, however I cannot seem to submit any information. When I try, the page reloads, followed by multiple uncaught errors observed in the console, including a cross site origin request block error (in the latest stable Firefox). My browser settings use the standard browser privacy setting, and custom DNS.

Regarding the error I was trying to report, I am unable to change my password, receiving "incorrect password" despite entering the correct current password. In the browser console, a POST response with error 400 is shown.

I've been trying to install an add-on that is in the .zip format. I set xpinstall.signatures.required to false and restarted the browser, yet Firefox keeps telling me the add-on cannot be installed because it's not verified. Is there a way to change this?

With some emails in Outlook on Firefox, clicking on a link within the email gives me a new blank window, with its address line saying something like this: (name of original site, then) ".list-manage.com/track/click?u=ca38acd 82fe622b7" etc etc... This doesn't happen with all emails, but often enough and in some of my most-used sites... I'm on a new HP desktop. Can anyone help?

I can open an email or a google search for this particular website, Sundance, click on an item which then opens on my screen but Firefox is unresponsive when I click within this item screen for details like available sizes and colors. This is the only site that this has occurred.

Hi,

Just the other day I started getting these popups from "anti virus service" that keeps popping up on my screen. I do not nor never did have McAfee on my system. I did a deep search, and there is no program on my computer, nor in my startups, nor in my popups allowed relating to this. It is only a problem with Firefox. Any solutions?

Thank you, John

Firefox version is: 127.0 (64-bit)

My problem is that Firefox seems to be ignoring "#:~:text=highlight this".

Maybe there's something under about:config? I can't find it.

Thanks

Can you suggest any functions or apps that I must or should avoid? It's important that I NOT use a VPN, and that I use 'open-source' in a probably 'shared access' situation. GRM PL

I went to this site, no worries, nothing there but asks you to click...which you should not do. It says to copy the fix and paste it into the windows shell... sounds obvious, it's a scam. Except, this is a major funding company.

So the question is, is this legit from firefox? Or is that what? Go to myforwardsavings.com and you'll see what i mean. Or, see image i have included.

Hopefully someone up the chain in firefox can let me know. As i intend to report them if this is nefarious. Thank you.
