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 -- I'm getting quite a few page crashes that seem mostly tied to YouTube, although not exclusively. I only recently swapped over to Firefox from Chrome because I was having similar crashing issues with that browser as well. This is after a fresh install of Windows 11 Pro and a number of different benchmark tests (no known issues with CPU, GPU, or RAM).

Since there are so many reports that all seem different, could someone help troubleshoot? I really can't tell if it's a browser problem, maybe something with my MOBO or PSU or other hardware.

"Profile Missing" Error

Hello, When I went to launch Firefox after starting up my PC this morning, I was greeted with: "Your Firefox profile cannot be loaded. It may be missing or inaccessible".

I went right to the Mozilla forums and found the help page [https://support.mozilla.org/en-US/kb/how-run-firefox-when-profile-missing...] . In this article it detailed how I should go into my AppData, then Mozilla, then Firefox, and look to see where my profile.ini file is. My profile.ini file was there, alongside the installs.ini and a few other folders. I attempted also to launch the profile manager using run and the "firefox.exe -P" command, but I got the same profile error as when I tried launching the app. The help page then recommended deleting the profile.ini file and then launching Firefox to hopefully remake the default profiles.ini file and enable me to launch Firefox, so I attempted that. When I tried relaunching Firefox, the profiles.ini file did not re-appear in my Firefox folder.

I then tried deleting the Firefox folder itself, and relaunching Firefox. This resulted in it being remade, but with just 2 folders left: Crash Reports and Pending Pings. Obviously that's not ideal, so I right clicked the Firefox folder and used the Windows "Previous versions" feature to restore the Firefox folder to a backup of how it was this morning. I then re-tried launching and I still got the same missing profiles error message. I also briefly attempted manually making a new profiles.ini file with notepad, and pointing it towards my Profile withing my Profiles folder, but that still resulted in the same missing profiles error.

This is basically where I am at now. I have confirmed that I do in fact see my actual profile in my "C:\Users\****\AppData\Roaming\Mozilla\Firefox\Profiles" folder, and as far as I can tell my profiles.ini file correctly points towards it. I did another reset of my Firefox folder to a backup of where I was at this morning before attempting anything. I can confirm my Windows account (Admin, and only account on the computer) has full read and write access to all Folders and files within the Mozilla folder, although I will mention some of the files in the Firefox folder were marked with the "Read-Only" attribute (not sure if that matters, but I tried unchecking those and still no luck)

As far as I can tell I have thoroughly exhausted all the easily accessible tips on the internet for solving this, so I am wondering what to try next?

TLDR: Error: Your Firefox profile cannot be loaded. It may be missing or inaccessible" Already Attempted (And failed): -deleting and prompting a remake of the profiles.ini folder -using firefox.exe -P to launch Profile manager -deleting Firefox folder to prompt a remake of that -multiple uninstalls and reinstalls of Firefox -manually remaking profiles.ini file after it didn't come back after deletion

Will link images of (1) profiles.ini file. (2) Profiles folder.

I am having issues signing in to the playstation store using firefox. It works on edge (although I have the same issue in ungoogled chromium). I have tried refreshing but that didn't work. I uninstalled it and deleted all mozilla folders in appdata, then tried again without signing in to my mozilla account on a fresh install but i'm still having the issue. It might be a windows configuration issue because I don't see why this would work on edge but not on firefox. I've tried disabling all cookie and tracking protection features but I still have the same issue.

Today, Firefox stopped playing audio on Facebook videos and won't play Netflix videos at all (Netflix error code: F7701-1003). Youtube works fine and has audio, but several other video sites I've tried have video but no audio. It was all working fine yesterday and I haven't changed any settings.

These websites work fine with both audio and sound on Microsoft Edge on the same laptop, so this is a problem exclusive to Firefox. OS is Windows 11 Home 23H2, Firefox is latest version (129.0.2)

Things I've tried: 1. Refresh Firefox settings 2. Download and install fresh copy of Firefox 3. Toggle DRM content in setting on/off - no difference no matter what is selected 4. Ensure that 'remember history' is selected 5. Check for Windows updates 6. Uninstall audio driver, restart and fresh install of audio driver 7. Ensure it's not in private mode 8. Turn off all extensions 9. Check volume mixer allows sound for Firefox 10. Clear the cache and cookies

I can't find any more suggestions on the internet, so any further suggestions welcome!

I just switched to Firefox from Chrome, because Chrome was crashing all the time.

All I want to do is sync my computer, laptop, phone and Ipad's reading list. I want to be able to see an article on one device, add to the reading list, and have it on all devices.

I'm logged in under the same name on all, and it says sync is on, but the reading lists are different.

Hello, I'm experiencing an issue with tab groups in Firefox.

  • I use multiple tab groups in my browser.
  • Normally, if I close the browser (without manually saving the groups), Firefox restores everything exactly as it was when I reopen it including all my tab groups and their current tabs.
  • However, if Firefox crashes while the groups are open, I run into a problem:
 * When I restart Firefox after the crash and try to open my tab groups, all the recent tabs are missing.
 * Instead of restoring the most recent state of the tab groups, Firefox loads an old, manually saved version from the past.
 * Any recent changes to the tab groups are completely lost.

This has happened multiple times now.

    • System Info:**
  • Firefox version: 141.0 (64-bit)
  • OS: Windows 11

I'd appreciate any help or suggestions to prevent this data loss after crashes. Is there a way to make Firefox auto save tab group states more frequently, or restore the most recent session even after a crash?

I am trying to manage Firefox for company devices via Intune and would like to know if there is a way to uninstall all extensions/add-ons besides one or two approved ones.

I have been able to import the Firefox AMDX into Intune and have made a policy to install uBlock (which works without issue) and I can uninstall specific extensions/add-ins via their Extension ID (also without issue), however I can't see a way to uninstall all extensions. If I try and put a wildcard in the Extension ID field, nothing is affected.

We have a large number of devices with their own user-installed extensions so auditing this and then updating a policy manually with specific extension IDs may be quite painful.

Recently we've began installing Firefox 140.2.0esr to our environment via the .msi file that Mozilla provides, however we're running in to a very odd incident.

After approximately 24 hours from installing Firefox esr to devices, it appears that the application is "updating" to 141.0.3 on the "release" channel. As far as I'm aware, this shouldn't be possible to begin with. But we've applied these settings via GPO:

Computer Config > Policies > Admin Templates > Mozilla > Firefox Application Autoupdate = Disabled Pin updates to a specific version = Enabled = Set to 140.2.0 Background updater = Disabled Disable Update = Enabled Manual Update Only = Enabled

After applying the GPO, confirmed this appears within the registry:

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Mozilla\Firefox\ AppAutoUpdate = 0 AppUpdatePin = 140.2.0 BackgroundAppUpdate = 0 DisableAppUpdate = 1 ManualAppUpdateOnly = 1

At this point, I'm at a loss. We cannot have rapid release be what's installed in our environment. Is there something broken with 140.2.0 or are we doing something wrong here?
