Firefox Community Forum

the metamask extension has quit working. The error message appears: MetaMask had trouble starting. This error could be intermittent, so try restarting the extension. Error details An unexpected error occurred.

This has been going on for a week now. There might be a bug in firefox?

Hi

We are looking to block the ability for a user to store or access saved credentials in the built-in password manager within firefox on mac and we used the following plist to push out a policy via JAMF

While we were able to get the password autofill/prompt disabled, we can still access the manager to view or add credentials manually.

Looking to see if there are some other parameters that can be used to accomplish this ?

<plist version="1.0">

 <dict>
   <key>DisableMasterPasswordCreation</key>
   <true/>
   <key>PrimaryPassword</key>
   <false/>
   <key>OfferToSaveLogins</key>
   <false/>
   <key>OfferToSaveLoginsDefault</key>
   <false/>
   <key>PasswordManagerEnabled</key>
   <false/>
 </dict>

</plist>

I get asked to update Mozilla every time I get on my computer.  It asks if I want to allow it to make changes to my device.
I never had to do that before. Why is that happening now? Is this Update request legit?   how do I disable it or customize  so that Mozilla asks me for an update only when there actually has one?

I have dismissed this request for the last week or so. Today, my browser would not work till I hit the Update button. What is going on? Is this from you Mozilla or have I been hacked? (I have McAffee security) I also updated my system to Windows 11 a few months ago. bold text.

Any Ideas what is going on? About July 21st, 2025 I started noticing with a couple of browser tabs open, a new tab opens autonomously and flitters in the new tab name area, what "looks like a TagID", then closes by itself. I define "looks like a TagID" as something that looks like a tag at end of article link in popular newsletters I see, and appears in the url bar of the linked article.

The occurrence of the new tab happens when I open the browser, within 1 minute and occurs randomly during the session, perhaps every 20 minutes.

My first suspect/assumption is I am always signed into Mozilla when I open Firefox 141.0 (64 bit), processing an update now, Aug 5 2025. I have subscriptions to VPN and Monitor and I have sync (passwords and bookmarks) with my mobile instance of Android Samsung Galaxy phone.

My Desktop is set up as Windows 11 pro with one employer InTune acount for Microsoft but I limit that work to Edge browser.

We have an enterprise web application that utilizes Primefaces for frontend UI. With a newest version of Firefox ESR 140.2.0 we noticed that input field values history is not saved. So the values are not proposed to the user wen he enters form data again. Problem is not available in Firefox ESR 128.14.0. Old input field values saved in 'formhistory.sqlite' before Firefox was upgraded to 140.2.0 are still available for the user.

Hi,

I clicked refresh firefox before I uninstalled the old version, then this "Old Firefox Data" folder was generated on my desktop. After installing the new version, I think I don't need this backup folder, but I was not able to delete this old data folder. It's telling me I don't have the authority, but I am the administrator. Can anyone here tell me how to delete this folder please ?

Thanks!

The text size used on both the menu bar and tool bars is way too small. I've tried a couple of 'fixes' I found online, but neither of them worked. Surely there must be a way to increase the minuscule fonts used on the menu bar and toolbars?

Unfortunately, this solution from 9 years ago also completely removes the preview thumbnails for images that we drag on pages. Isn't there a way to disable the tab preview thumbnails only?

I am aware that Windows 10 will continue seeing support for the foreseeable future, but what about older versions and builds of 10?

I ask because I'm currently on a machine that physically can't update beyond version 1909 build 18363.1198 due to an issue that occurred on my machine in November 2020. So I've been stuck at that version and build of 10 for basically the last five years. While I'm trying to see if I can update it to 22h2, the last known version of Windows 10 with the hopes of enrolling in the extended security updates, that may not be feasible due to how old the mahcine itself is. Will Firefox continue to support all versions of 10 for the foreseeable future and not just those on the ESU? If so, great. If not, what version will be the last that can support the version I'm on? I don't have a Windows 11 machine yet on a full time basis (I'm testing an 11 machine out, but I may not end up keeping it) and I prefer 10 to begin with, so I would like to know when I need to stop updating Firefox itself, so that I can be sure I'll be able to keep using the browser with my current OS.

Mudei de computador e ao entrar com a chave de recuperação de conta, é informado de que ela está inválida. Ao tentar alterar minha senha sem a chave é informado erro, que não é possível realizar a operação. Quando tento alterar minha chave de recuperação , só tem opção de fazer a alteração entrando na minha conta, sendo que estou tentando alterar por não ter a chave de recuperação. Como posso sincromizar novamente ou gerar uma nova chave?

I clicked on a link in a forum site - pentaxforums.com - that should have pulled up image from a private web site but I think the url has been hijacked, the image didn't appear and instead the browser started pinging alerts. I have run avast anti virus and malwarebytes, these found suspicous malware (trojan, key clone) and rebooted, but these alerts still keep appearing, however I am wondering of the browser alert system itself has been compromised. See screenshots. if I click on one it seems to be trying to go to a suspicious url. any advice appreciated Marcus Brown
