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 keep getting a popup about using an older version and creating a new profile. I already created a new profile a few days ago so I cannot keep creating new profiles every time firefox deploys a new version and would need to open firefox to update the browser version.

This is really annoying. I've had that feature disabled since I first started using Firefox as I feel it defeats the purpose of incognito tabs to make it obvious when you have them open, and I prefer keeping all my tabs organized in a specific way

I've checked about:config and that feature is still set to false, I've checked about:studies and there's nothing that looks like it would impact private browsing. I've tried restarting both Firefox and my computer, the tabs are still separate

Anyone have any ideas on what to do now?

Every time I try to make a comment to an article in Yahoo News, it gets rejected. I can't even post the word testing and it gets rejected. Attached is a screenshot.

Hello,

I am on a LinuxMint machine (21.2 - Cinnamon), using Firefox for LinuxMint 001-1.0 - 127.0(?)

When trying to access https://onlineradiobox.com/us/draculascastle/, Firefox reports a playback error. Chromium is opening it with no problems.

Firefox is also opening other stations on the onlineradiobox, without a problem. Tried all kinds of setting changes to no avail.

Can you please HELP?

Thank you for your time.

Have used Firefox for decades and suddenly it is having problems. If I surf around and have a few tabs open, some of them might crash. Firefox tries to restore them and sometimes it works and sometimes they just crash again immediately. I can go to Amazon and the page won't load completely so I can't do anything. If I try and close Firefox it won't close, it is frozen. And often, pages just load very slowly even though my internet connection is strong. This just started about a month or so ago. I have refreshed Firefox, updated it, and checked the systems on my computer. All my internal diagnostics returned "no issues." So it has to be the program.

When I reboot a Windows 10 computer and click once on the Firefox icon on the Taskbar, (1.) Firefox does not open full screen although when closed it was full screen. (2.) A second Firefox window opens with Yahoo on a Tab and also not full screen. Please fix!

Need to know why this problem of Firefox (on Linux) suddenly arose. When attempting to make audio or video calls it responds with, Does not work on Firefox browser. Yet it continues to work with about half my contacts.

Hi,

For some time now, when I download a .pptx, .xlsx og .docx Firefox changes the file format to .pdf when downloading the file. I then have to manually choose the correct app for opening the file, overrule error messages and delete the ".pdf" when re-saving the file even though it recognises it is not really a pdf file.

I've tried to change the Firefox settings, clearing cache, restarting or deleting in config and other small attempts to reboot whatever suddenly started to cause this problem. As far as I can see, it is not an unknown issue, but I've not yet been able to find a solution to my problem, which is getting on my nerves.

Hope you can be of help.

I haven't downloaded anything recently (at least not that I know of) and for the past two days now every time I open up firefox, the search bar and images glitch white. You can't see what you're typing and when you go to images on google, all of it turns white. It happens to every website I go to, certain things turn white. Doesn't happen with Chrome, just Firefox. I've cleared the cache and data on it but that doesn't do anything. I've restarted my laptop and tried to make sure it wasn't my laptop that was the problem. I'm nervous to uninstall and reinstall cause I don't want to lose my passwords saved here.

i keep getting sent to .ca sites instead of the .com that i had typed in and wanted to go to ie: yahoo.com discovery.com

There was no yahoo.ca or hotmail.ca when i got my email accounts and i only deal with originating networks Discovery.com not ripoffs like ctv.ca/discovery.

Firefox is my default browser...but when i open it.. MSN Browser opens first and i have to 'click' the+ add button to go straight to firefox...why is that happening? I have checked how to stop MSN browser loading from youtube video...adjusting the reg-edit process..rebooted and redone a few times....but still when i click on my firefox app...this is what happens every time?

Hello, I am currently facing a problem. Yesterday, I passed a message from https://firefox-source-docs.mozilla.org/setup/linux_build.html#building ---The official documentation for firefox on Linux compiles and installs a Linux system with aarch64 architecture on an Ubuntu host with x86 architecture. In fact, I only modified a file called ". mozconfig" and added the following information: "ac-add-options -- target=aarch64-linux-gnu mk-add-options MOZ-OBJDIR=@TOPSRCDIR@/obj-aarch64-linux mk-add-options AUTOCLOBBER=1". After compiling for a while, I obtained a folder called "obj-aarch64-linux". I used the command "file /obj-aarch64-linux/dist/bin/firefox" to check the properties of the knowability file as follows: " firefox: ELF 64 bit LSB shared object, ARM aarch64, version 1 (SYSV), dynamically linked, interpreter/lib/ld Linux arch64. so. 1, for GNU/Linux 3.7.0, BuildID [md5/uuid]=6b1bede035b0d0bc9930d0d4d88c3c14, with debug_info, not stripped ”. I think I have completed cross compilation, so I compressed the "obj-aarch64-linux" folder on a USB drive and copied it to my aarch64 architecture development board. And when I tried to launch the browser on the development board using the "./obj-aarch64-linux/dist/bin/firefox" command, I received an error message saying "Couldn't load XPCOM". It is worth mentioning that firefox is installed by default on my development board, but I need to compile and install its source code, and local compilation cannot be achieved on my development board, so I made the above operation. So, I want to know how to solve this problem, or if there are any errors in my cross compilation process. Thank you for your help and look forward to your prompt reply.

Hi, Since the update today to 127.0 My sidebar bookmark will not load when I open Firefox. Here is what I have done so far,

Uninstalled Firefox and use the restore on reinstall. didn't work deleted the xulstore file in 3 location. didn't work Removed Firefox using Revo Uninstaller and installed from the local setup file. didn't work Uninstalled ad-ons that used the sidebar, IE Video DownloadHelper, Sync my account, and tryed the step above again. didn't work I use Revo again and did a search for any firefox file, deleted old firefox folder on desktop and any file I could find with a link to the browser. Reinstalled from local file.

When Firefox started this time there was no profile to log in my account "" password etc "", I did a test and the sidebar was working correctly. I then activated my account and the side bar stop working on restart. Not that I did a sync after removing a few ad-ons, see pic for left addons.

I use Firefox (currently on version 127.0) and starting this weekend I noticed a strange behavior. When I initially go to the NPR.org site (and only that site) everything works fine, but once I scroll down past the first two articles all of the links on the page stop working. The cursor that usually changes from an arrow to a finger does not change, the links do not change color as they should.

This only happens on NPR.org, and it only happens with Firefox (I can use Chrome at the site works fine.) Therefore I assumed that something changed at NPR.org so have reached out to them, however, I thought I would ask your team if they knew of anything going on?

Thank you tom balent

Whenever I try to download anything, it automatically fails. The problem just started recently and I don't know what could have caused it because I haven't done anything that could affect downloads to my knowledge. Things I've already tried are

• Reinstalling firefox (including full uninstall via "Revo Uninstaller"
• Updating firefox to the latest version (127)
• Disabled all firewalls
• Chose the save location
• Disabled all parental controls in windows
• Chose the "don't enable HTTPS mode" (https://support.mozilla.org/en-US/questions/1414064)
• Tried firefox & windows safe mode (https://support.mozilla.org/en-US/questions/1442742)
• Chose a different save location inside my computer (a folder other than downloads)
• Cleared download history
• Ran a chkdsk on windows

The thing is that everthing else of firefox works (browsing the web, watching videos, etc), it's only the downloads. It's also not a computer problem I think because I can download on other browsers (such as chrome and pale moon). Any help asap is appreciated.

Why can´t my email within Outlook not be shown. "error" Your email cant be shown at the moment. Try again lather or check your Internet connection.

In other browsers an android phone there is no problems. P.s. I have just updated Firefox. to version 127 for Linux Kind regards Bent

For a while now, I've been having recurring issues with Firefox desktop freezing and becoming totally unresponsive. If there's any pattern to what causes it, I haven't been able to notice it; sometimes it happens as soon as I open the browser, sometimes it happens after several hours, sometimes it happens twice in ten minutes, sometimes it happens twice in a few hours (however, I can count the number of days it's happened less than twice in one day in the past few weeks on the fingers of one hand). When the browser freezes, it becomes totally unresponsive - it doesn't fade or display "Not Responding", and Task Manager shows nothing abnormal, but it doesn't accept any input at all, any video or other animated material that may have been displaying freezes, and it can only be "fixed" by force quitting from the task manager and reopening. This is exclusively a firefox issue; other programs open at the same time as the browser freezes are not affected.

The only real lead I have as to what could be going on is that sometimes, things don't freeze all at once, but in a cascading effect. For example, tabs, bookmarks, etc. might not highlight when moused over, but still accept the clicks, or selecting another tab might causes the address bar to display the URL of the selected tab, but the screen displayed in the window will not change. Once these cascading changes start, they generally progress to total freeze before I have a chance to do much with that information (only a few seconds), but it's unusual enough behavior to be worth noticing.

Things I've already tried that haven't fixed the issue:

• Reducing the number of tabs used and otherwise reducing Firefox's system resource usage has not impacted the problem in any way.
• Running in Troubleshoot Mode has not had a consistent effect on the problem (the most recent time I did, the browser ran stably for longer than I could stand to use the internet without my ad blocker, but this is only one data point in an already inconsistent spread; prior instances of the problem have occurred in Troubleshoot Mode)
• Disabling hardware acceleration has not fixed the issue.
• The issue has persisted through multiple refreshes and at least one full uninstall and clean reinstall.
• The issue persisted after creating and switching to a new profile multiple times.
• The issue persisted after renaming places.sqlite
• The issue persisted after clearing cache and cookies multiple times.
• The issue persisted after clearing downloads and history.
• And very likely some other stuff that I'm forgetting, I've been trying to fix this on my own for a while now.

Hi,

I have an issue with color profiles that I'd like some help with. For my setup, I'm using a thinkpad with a wide gamut display running in fedora.

The issue is that an image exported from Darktable looks overly saturated in Firefox. I found I was able to fix this by specifying the color profile using the flag `gfx.color_management.display_profile`. However that profile is the OS default, and according to Firefox it should've been picked up when querying the OS.

How can I see what icc/color profile Firefox is using? Alternatively, what method is Firefox using to query the OS for its default profile? Thank you.

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?
