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?

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.

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?

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

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

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?

Hi,

I factory restarted my computer and reinstalled Firefox. When I signed into my Firefox account, all my bookmarks showed up but none of my tabs were loaded. I figured out how to load my tabs up from my previous session but all my bookmarks then deleted. I tried to re-sync but none of the tabs showed up. When I try to restore my bookmarks from the manage bookmarks library, it does not appear. I do not have a backup file for my bookmarks.

When logging in to the online bank at DNB with Bankid, this error appears:

"A communication error has occurred. We are experiencing a communication error between your browser and the user site. The reason may be slow internet or problems with your browser. Try again in a little while. You can also try to delete cookies and browser data in your browser or try a different browser. Error code BID-5000 Reference DXP4VKOE Date 12/06/2024"

No other browsers show this error. I've tried Edge, Chrome, Vivaldi, Brave, CC Cleaner. The error starts after version 125.0.3. Today a new version 127.0 arrived. The same error appears.

I have uninstalled the latest version and reinstalled version 125.0.3. Then no error message appears. I have deleted cookies and browser data, but the error message persists. To your info, I've tried also on other PC's and the same Firefox version, and the same errormessage appear.

I look forward to you having a solution to the problem, otherwise I will have to use browsers that do not show this error. As I prefer Firefox, I don't want to use other browsers. But if the bug can't be identified and fixed in newer versions, I'm not happy with firefox and will use other browsers..

I want replace firefox Windows Mozilla MSIX 1- 0 package browser from ms store with regular downloaded version but I do not want to lose all my settings.

How do I go about this?

Thank you!

The bookmarks disappeard on the toolbar or in the library even though the sites that were previously bookmarked are still marked with the blue star. Comically it still shows my recent additions even though they are nowhere else to be found.

On mobile the bookmarks are still there but resynching, reinstalling, restarting didn't work.

When i want to bookmark the disappeared ones again, they won't be saved and are gone again the next time I start the browser.

It's really annoying, I had a lot of them and I don't want to use desktop shortcuts or use another browser but I might just have to.

I woke up this morning to my home directory having been remounted as read-only (it has its own dedicated hard drive at /dev/sdd1). I ran e2fsck and things looked good, so I restarted and things were fine again.

However, whenever I open Firefox, it hangs for about 1 full minute before it goes haywire and renders the entire system essentially unusable since being able to access my home directory is vital. The following is visible in dmesg:

All other programs that I use daily do not cause this issue. No clue what to do here. LibreWolf works fine - that's what I'm using now that Firefox breaks everything and basically forces me to restart if I want to use my computer normally.
