The icon for private browsing has recently re-appeared on my taskbar despite having browser.privateWindowSeparation.enabled set to false in about:config.

I've had this setting configured ever since the update which completely changed the appearance/behavior or private browsing and it has worked correctly up until today (14/06/24).

Is there a new setting that I have to adjust in order to "merge" the windows together as I'm not a fan of having the private browsing icon on my taskbar.

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?

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?

As of a few days ago whenever I start Firefox the window appears with the Bookmarks sidebar panel already opened. I click the "X" on the sidebar and it will close - until the next time I start Firefox. If I choose Menu->View->Sidebar->Bookmarks and uncheck it the panel will close - until the next time I start Firefox. No matter how the Bookmarks sidebar is closed, it will always reappear when Firefox is restarted. Even if I switch to some other sidebar, Bookmarks will replace it on startup.

I've searched about:config and found no setting which seems to control sidebar behavior on startup.

I assume this is the result of some recent update. Is there no longer a way to permanently disable the Bookmarks sidebar?

Today for the first time after the latest update 127.0 (64-bit), my many firefox pages and tabs crashed and closed and a pop up to send crash report.

So I have fired up firefox again to find only a single page opens up, I have lost probably 16+ pages with multiple tabs on each, been like that for months, I have 32GB memory so there is normally no issues or slowness. However after the crash, even though only a single firefox page is open, windows task manager shows Firefox (20) and if I expand the task, I can see each firefox is taking lots of memory.

So it looks like the old session pages/tabs are still there somewhere but not accessible, I would like to get them back if possible. I went through reseting it to default, disabling the add ons etc but nothing has worked.

Hello!

Started up Firefox today and these whited out boxes started appearing over my search bars and random part of the screen, such as the descriptions of different articles on my home pages, extension and theme information in my settings, and different tabs (see pictures 1 and 2). The text is also white, making it almost impossible for me to see what I'm typing or selecting in the search bar (picture 3).

I've already tried some tips that I found on the forums such as changing the hardware accelerator, making sure my extensions and add-ons were up to date, etc. When I go into troubleshooting mode, the boxes disappear and Firefox functions normally, but when I tried turning off all my add-ons and themes on the regular browser, the problem still wasn't fixed. I did a full refresh of the browser, hoping that would help to reset whatever was causing the issue, but that didn't help either.

Any advice or troubleshooting tips would be greatly appreciated!

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.

Is it possible to install Firefox (or at least the profiles) onto an external SSD (i.e., not the C: drive)? If so, how?

Note: this is not about migration/backup/recovery of profiles. Nor is it about where files are downloaded by default.

Windows 11 is consuming nearly all of the C: drive. I badly need to get Firefox (and later Thunderbird) onto my E: drive. I further note that the installer gives no options whatsoever as to the destination drive.

Most of the help I've found on the web is clearly outdated.

In previous versions I was able to open around 15-20 tabs before X button disappeared from them and I was no longer able to close them without activating them first.

Now this happens much earlier - only 10 tabs is enough on my 1080p 100% scaling desktop and 9 tabs on my 1080p 125% notebook.

X button is present if you have 10 tabs or less, but disappears with 11 tabs, when there is still plenty of space on tabs to click on X!

I compared it to brave and in brave you can still have 22 tabs opened before X button disappears!

Anyone has any method to force presence of x button? This is really annoying as I often have much tabs open and close only 2-3 of them. Now I have to open each one again to be able to close it.

Hello!

I am a heavy user of Firefox: daily & around 8 hours a day.

I usually use alt+shift+left/right-arrow to select a few words to the right / to the left. With the latest update (mandatory because this is a work-administered) laptop, the new behavior is that tabs are changed.

I want any solution to revert this to standard (past) behavior (preferably not an extension). Looked around in about:config but could not find anything to toggle on/off.

This is highly annoying as I've had this workflow for literally years. Even opening this ticket I encountered the issue more than 3 times as I was phrasing the message and had to delete & rewrite some stuff while also have other tabs open in the same Firefox window.

Would highly appreciate your timely response!

Thanks a lot! -- John

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?

When using Firefox (latest) and attempting to login into a website I get an error (see attached image) generated by the host's server's firewall. It appears it thinks I'm a bot. When I use Firefox's privacy mode I don't get this error. I would prefer not to use privacy mode. I contacted the administrator of the website I'm attempting to access and he couldn't offer any help.

When I use Google Chrome browser I don't encounter the above problem. This leads me to believe it's not an issue with my Avast Anti-Tracking and Antivirus settings.

Any help would be appreciated.

Back in October 2022, changes were made to how private windows appear, separating their icon in the OS taskbar, giving it a new icon, and putting a badge on the top right of the window.

At the time, support threads (such as this one https://support.mozilla.org/en-US/questions/1393494#answer-1542568 ) suggested changing three options to revert these changes: -browser.privateWindowSeparation.enabled -browser.privatebrowsing.enable-new-indicator -browser.privatebrowsing.enable-new-logo I really dislike how these changes look, and so immediately followed this advice. In my advanced options, every one of these is still set to "false" to this day. However, after a recent Firefox update (my current version is listed as 127.0), these no longer seem to have any effect making the new look the only option.

I would strongly prefer to at least re-combine the taskbar icons for standard and private browsing into a single icon. Is there any way to do this in the current update, or is this change permanent going forward? If it is permanent, would reverting to version 126.01 risk losing my current Firefox profile?

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.
