Running Firefox 133.0.3 on Windows 10 22H2

The last week or so, when I try to download my photos from iCloud, Firefox blocks the download, saying it contains a virus or malware. Of course it does not - it's a zip file of screenshots! Running a scan on the folder once unzipped confirms there is nothing malicious in it. Can you fix that please?

Some Keyboard Shortcuts No Longer Work.

Hello. This question concerns the Windows 11 desktop version of Firefox.

I have long used the Home and End keys on my extended keyboard to scroll to the very top of any given page in Firefox (Home) or to the very bottom of that page (End).

But, lately, I notice that, for no reason I can figure out, Firefox no longer responds to those shortcuts. Now, when I tap Home or End, the page may, at first, scroll up or down slightly but not to the top or bottom. If I press Home or End again, nothing happens at all.

Sometimes, if I press Ctrl + Home simultaneously or Ctrl + End the page will scroll to the top or bottom respectively.

Why has Firefox's behavior apparently changed? Is there an issue with my keyboard or operating system settings? (I use a Logitech G915 keyboard.)

Please let me know how to restore Firefox's shortcut functionality, where I can tap just Home to scroll to the top of a page or only End to scroll to the bottom of a page.

Thanks and be well.

Hi, We are using Horizon VDI terminal server. Firefox is installed on these servers. Some users get Firefox is already running but is not responding error. Ending Firefox via task manager does not work. I log off the user and have them log in again, but it does not work.

When I check, I see that the user's profile file cannot be created on any terminal server.

Is there a solution to this problem?

Firefox 136 broke my custom new tab page, how do I fix it?

I'm on Linux.

I've been using this method to setup a custom new tab page for Firefox for almost 4 years, and it has worked great: https://jamesnorth.net/knowledge-base/article/firefox-new-tab-page

---

Navigate to /usr/lib/firefox.

Create autoconfig.cfg:

// var {classes:Cc,interfaces:Ci,utils:Cu} = Components;

/* set new tab page */ try {

 Cu.import("resource:///modules/AboutNewTab.jsm");  
 var newTabURL = "file:///home/james/ff/index.html";  
 AboutNewTab.newTabURL = newTabURL;  

} catch(e){Cu.reportError(e);} // report errors in the Browser Console

Create defaults/pref/autoconfig.js:

// pref("general.config.filename", "autoconfig.cfg"); pref("general.config.obscure_value", 0); pref("general.config.sandbox_enabled", false);

---

However, upon updating to Firefox 136, I only get a blank page. All of my autoconfig files still exist in /usr/lib/firefox.

When I create a new tab with Ctrl+T, it's a blank page. When I create a new window, it loads the local page I want it to load with the file path in the URL (which it never had before; the URL bar was blank in Firefox 135). So it seems to be partially working.

Any tips?

On websites, thumbnails will not display but appear instead as white boxes with small blue question marks. I am using a two year old ipad and my internet speed is 180.

This is a new bug, as of today.

If I click on each thumbnail the image displays just fine, but that is not ideal.

On a reddit forum, someone suggested typing about:config into the search bar but nothing happens when I do that.

Any ideas?

iCloud has stopped signing in on the Firefox browser for Windows. I contacted Apple Support and they told me that this is an issue on Firefox's part, and told me to try signing in the next morning and they guarantee it'll work. It did not. In fact, it has been over a week, and it still does not work.

When I enter my Apple ID and Password, the website gives me an error "Failed to verify your identity. Try again." The website does NOT send me to the 2fa screen, yet it still sends a 2fa code to my iPad nonetheless.

As Apple has said this is an issue on Firefox's part, I am posting this here. Attached is a screenshot of the error.

Recently I have had several experiences with captcha when paying for something with a credit card. I check the box saying I'm not a robot, get a green arrow, but then the purchase does not go through. Error message says I failed to satisfy the captcha, even though I was never shown the grid of images. Just now I tried the same operation with the same company invoice using Chrome, and it went through successfully by just checking the box I'm not a robot. This is very inconvenient.

I'm using Firefox v136.0 on a Windows 11 host.

Each time I open Firefox the software prompts me two times (via a dialog) to enter the primary password. (I previously enabled and defined a primary password.) I'm also prompted twice to enter the primary password when I open the Firefox's SETTINGS page. This happens in "regular" and SAFE mode. I do not have any extensions installed nor themes installed/enabled. The only plugins that are installed are "OpenH264 Video Codec provided by Cisco Systems, Inc." and "Widevine Content Decryption Module provided by Google Inc."

When I delete the primary password, the browser does not prompt me to enter the primary password on startup or when opening the SETTINGS page.

FWIW, I've tried the following sequence, but the problem persists:

  1. Uninstall Firefox
  2. Delete as many temporary files as I can in $HOME\AppData\Local\Tmp\
  3. Delete $HOME\AppData\Local\Mozilla\
  4. Delete $HOME\AppData\Roaming\Mozilla\
  5. Reboot
  6. Reinstall Firefox
  7. Open Firefox and add a primary password
  8. Close and reopen Firefox

When I reopen Firefox, it prompts me twice to enter my primary password. When I open Firefox's SETTINGS, I am prompted twice to enter the primary password.

Any suggestions as to how I can convince Firefox to not prompt me twice for the primary password when opening the browser would be appreciated.

Hi there,

I’m using the Firefox Multi-Account Containers extension and would like to remove a site that’s been set to "Always open in [X] container." However, I don’t see a “Manage Site List” option anywhere in the container settings as seen here: https://support.mozilla.org/en-US/kb/containers

Here’s what I’ve tried so far:

   I’ve clicked the Containers icon and selected the gear ⚙ to edit a container.
   I enabled privacy.userContext.siteAssignments.enabled in about:config and set it to true.
   I restarted Firefox (with session restore on), but still no option appears to view or manage assigned sites.

I’m on Firefox Desktop (Mac), and I’ve confirmed that I’m using the official Multi-Account Containers extension.

Is this a bug, a UI change, or something I’m missing? I’d really prefer not to manually edit the containers.json file if there’s a built-in way to manage these assignments.

Thanks so much for any guidance!

Hello,

Suddenly some UI elements became color-inverted or almost completely black, such as the tab icons in the tab bar, the website icons on the New Tab page and some icons in the settings menu. Also, some websites appear to have this issue, but the Samsung website is the only one I found so far with this issue.

On the same day it happened I switched to an OLED HDR-capable monitor, so I assumed it would be related to HDR, but I played around with some settings and I'm not sure anymore.

What I tried: - hardware acceleration on and off - HDR completely on and off - default light theme and dark theme, no customs themes installed - all extensions disabled (I have no extensions that would influence graphics or colors anyways) - latest update already installed - nothing else changed in the Nvidia control panel as far as I remember

None of the above helped. Any advice on this is appreciated. Attaching some pictures with the issue. Using Windows 11.

Thank you!
