I-Firefox Community Forum

I am getting repeated pop up "alerts" from Firefox, McAfee and others about Trojan Horse and other viruses. I did not click on the links offered. How do I stop them from coming?

Following a recent Firefox update, 1.48.0 I think, the search box in the middle of the page no longer works, any attempt to type there ends up in the address bar. I have tried setting "browser.newtabpage.activity-stream.improvesearch.handoffToAwesomebar" to false and other suggested fixes on the internet but it made no difference. I am running Windows 11 Pro, fully updated. Hope you can help Regards Keith

I went to [https://support.mozilla.org/en-US/kb/firefox-backup] and under "Create a Firefox backup file" at step 3 it says, "Scroll down to Backup, and click Manage backup" but when I went there no such "Manage backup" option exists as you can see in the attached screen capture. So what gives? How can I "Create a Firefox backup file"? I am using Firefox v147.0 (64-bit) on Windows 11 Please instruct. Thanks RJB

How to edit shortcut keys for the extension- Read Aloud: A Text to Speech Voice Reader ?

When trying to assign a new shortcut of my choice, it gets deleted automatically.

I was able to do so in Chrome and Edge browsers.

Please help me to assign the same shortcut keys in Firefox also..

My passwords have been randomly disappearing from my PC. My android has the passwords intact but it will not sync in either direction. I have followed every instruction that I can find with no success.

On a couple of occasions, a successful sync has happened randomly a couple of days later.

On this occasion no syncing so far. (two days)

I am feeling that Firefox is becoming somewhat unstable, which is a shame as I have been using the browser since Noah was a lad.

Any ideas?

I know you can block it and opt out of the AI options in Firefox, but just wanted to voice my opinion.

We did not ask for it, nor do we want or need it. The bubble's gonna pop soon and then we are stuck with these AI artifacts.

By default the AI options should be blocked/off/opt out. If we want to use it, we'll opt in ourselves.

I am currently using Windows 11 (64 bit). I have installed Firefox in a separate drive instead of Local C to save space. Now that I have done so, the automatic update fails often which causes me to try and find the custom installation on the Firefox download page. I use https://support.mozilla.org/en-US/kb/custom-installation-firefox-on-windo... page to try to find the correct installer.

Unfortunately, the download page that I was directed to, I can't seem to find the custom installation setup. When I click download, it keeps giving me the automatic Firefox Installer and proceeds to add Firefox on my C drive rather than the Mozilla Firefox Setup Wizard.

Can someone kindly direct me to where I can download the Mozilla Firefox Setup Wizard to update Firefox?

Hello Mozilla Support Team,

I am writing to request assistance with recovering my Firefox Sync data.

I recently reset my PC and after reinstalling Firefox and logging back into my Firefox account, my bookmarks and saved passwords are completely gone. I believe the sync may have overwritten the server-side data with an empty local profile after the reset.

Account email: [edited from public] @gmail.com Approximate date of data loss: 02 25 2026

I had been accumulating this data for approximately 1 years and it is very important to me. Could you please check if there is any backup of my sync data on your servers that could be restored?

Thank you for your help.

When using the AI chatbot in the Firefox browser, I cannot click to the left of a certain coordinate only when Claude is open. This issue does not occur with other AI bots (such as ChatGPT or Gemini). What could be the cause? My environment is as follows:

OS: Windows 11 Pro x64 Firefox version: 147.0.4

Additionally, tabs are set to vertical display, and the sidebar expands only when the cursor hovers over it.

Thanks.

When I am using the Firefox browser and am on a site that asks for my email, there is a Firefox dropdown with a list of email addresses. There are many email addresses on this drop down list and I cannot find where I can edit that list.

Nothing is the Autofill settings comes up. Where is that list of autofill email addresses?

Good day! Initially, I installed Firefox version (x64 ru) 147.0.3. After updating via the "Help - About Firefox - Update" menu, I received version 147.0.4. However, there are two entries about installed Firefox in the Windows section "Installed applications": 1. Mozilla Firefox (x64 ru) 147.0.3 and 2. Mozilla Firefox (x64 ru) 147.0.4. Although one instance of the program is installed. How do I remove an extra entry? Thank you.

I have a question about deleting a Firefox profile. When I access the profile screen via "about:profiles," I see two profiles: "default-release" and "Default User." The "default-release" profile is fine because it displays the message "This is the active profile and cannot be deleted." But is it okay to delete the "Default User" profile? Should I also delete the files in the root directory of the C: drive and the local directory? If I delete the "Default User", will it be deleted as well?

Hello,

This morning Firefox stopped loading new tabs, which usually means it is due for an update and restart. On my work computer, updates are managed by my organization, so I cannot prompt it to check for updates directly, but rather can just restart the application and it updates once closed. Today when I closed the window then clicked the shortcut to reopen, it notified me the exe file had been removed and prompted me to open the Windows store and reinstall, which I did. I have no indication as to why it uninstalled. All of my bookmarks and other history appear to have been wiped.

I have been trying on the support site to see if this data is recoverable, but nothing has panned out so far.

I have used Firefox as my primary browser for almost twenty years and frequently encourage friends and family to use it if they don't already. I have never experienced anything like this before. I am hopeful somebody will be able to assist me where reading through support center options hasn't yet, but if this is not resolvable, I'm done- the crash helpfully wiped everything clean, after all.

Any suggestions or response is greatly appreciated. Best, Z

Chrome based browsers display dark pdf correctly. Firefox does not. see attached images. all extension are disabled.

I had to remove the Recommended stories from the home page. every source was a left leaning outlet. How is someone supposed to get a balanced news snapshot if all the sources have the same biased tilt?

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.

bold text Firefox has been my browser forever. When I tried to open it this morning I was invited to create a profile, so no profile, no Firefox..... I've never had to do this before and am reluctant because of the apparent threat of losing all my passwords and bookmarks. I'm 85 years of age so don't need this complication. Any help would be appreciated, complicated high tech answer will probably be beyond me. Brian.
