Diễn đàn hỗ trợ Firefox

Hello team,

I'm not sure what happened, but I was not able to open Firefox after restarting my PC. I currently run Windows 11 on a fully upgraded rig.

Up until today, I have been trouble free. Error 1: "Firefox is already running, but is not responding. The old Firefox process must be closed to open a new window."

I tried several options - and have been googling/trying several steps for a couple of hours (after each step, I restarted the PC):

1. Uninstalled and then Reinstalled a fresh copy of Mozilla 2. Attempted to use Command Lines to open Firefox https://wiki.mozilla.org/Firefox/CommandLineOptions 3. Opened Profile Manager and attempted to create a new profile - when I did this the new profile would not display in the Profile Manager, but it would display in the Profiles folder under Appdata [I tried this multiple times] 4. Deleted the profiles.ini file

After deleting the .ini file Error 2: "Your Firefox profile cannot be loaded. It may be missing or inaccessible." 1. Uninstalled and then Reinstalled a fresh copy of Mozilla 2. Opened Profile Manager and attempted to create a new profile. After following the Profile Wizard, another error pops up: "An unexpected error has prevented your changes from being saved."

I am completely stumped. I hope you can help, Sean

A while ago I made a Firefox account with my Yahoo email address as the primary email, and my Outlook email address as the secondary email. Eventually I realized that I didn't need my Yahoo email account anymore, so I deleted it, forgetting that it was being used as the primary email for my Firefox account. Now I can't remove my Outlook email from my Firefox account without verifying my Yahoo email account, and I can't even delete the Firefox account since it was made under the Yahoo email account as a primary email address.

Now I can't use my Outlook email address to create a new Firefox account either.

Problems that I faced: 1. There is no firefox window opened, but "new staff train - google drive" window name still appear. Please see attachments. ( the "new staff train" was a window that was closed long time ago) 2. Normally, when one minimises a window and clicks the firefox, the minimize window will pop up, but now it won't.

I did try to delete, uninstall and reinstall firefox, but the problem still exists. Please advise what I can do to solve this inconvenience. Currently, I'm using Firefox 89.0

So far i asked a handful questions here. Some are being replied while others are ignored. How do i get more attention on my questions and how is determined if they are important or not? support.mozilla.org behaves in a wired way here, it's not like a Forum. Im certain admins have full sight over all topics here while a normal user like me, feels pretty lost.

Why do some questions show the amount of views while others dont? -See attached screenshots https://i.postimg.cc/QtyPZ0Nh/1.png https://i.postimg.cc/q7QSjp9t/2.png

Hi there,

I'm using my PC for local web development. I use Firefox as my regular browser and recently, in order to distinguish between personal time and development time, I've established a new profile just for development purposes.

The local website I can't reach is "site.local.dev". My OS is Ubuntu 20.04 and that URL points to a local IP on my network (resolved via /etc/hosts file on my PC).

Funny thing is that: - In dev-profile: site.local.dev does not work => "Unable to connect" and the URL bar shows https://site.local.dev even if I force it to http:// - In personal-profile: site.local.dev does work :P

I have tried with CLI tools like "wget", "hosts", "ping", "telnet" and so on and the site loads ok. Even I have used Dillo (damn simple web browser) and the site loads ok also.

Things I've tried so far: - Suggestions at https://support.mozilla.org/en-US/kb/firefox-cant-load-websites-other-browsers-can - Suggestions at https://support.mozilla.org/en-US/questions/1011327 (similar issue, not exactly the same).

It must be a silly thing but I'm out of options now. Perhaps anybody has faced to this situation in the past: any suggestion on this issue?.

Thanks in advance, Ibon.

Can someone confirm if mozilla-api[.]com is an official Mozilla domain? It was registered 7 months ago with Namecheap registrar. I am unable to find any overlap with official Mozilla infrastructure and I suspect this is a malicious domain.

Greetings everyone,

I know this may sound like a strange question, but I'm very serious.

I just read an article that says Firefox is in danger of being shut down

I've always seen Firefox as the most trustworthy web browser and so I was planning on using Firefox as my main web browser for the long term. However, after reading this article I've become very anxious.

Article link: https://news.slashdot.org/story/20/08/15/1955237/can-firefox-be-saved

I'd really appreciate any advice.

On one computer I have deleted everything from Firefox including the folders within Apps Roaming except for one folder. There in one folder "41A66E7EE5E1" within Profiles which I cannot delete. It holds the files prefs.js and sessionCheckpoints.json which were created at 20/02/2021 and I cannot delete those.

My new installation is dated 24/07/2021.

There is nothing in the properties of those two files to suggest an issue. I do find however that when I seek to change the Property/Security to Administrator (I should be able to do that) I receive a dialog box that "the file or directory is corrupted and unreadable".

Please advise on how I address this.

I just allowed an update to my computer from Mozilla called software updater and now I can't use duckduckgo to search the web. I had to use google to get to this page for help. Let me know right away how to remove the mozilla updater from my computer and get back to the firefox browser that works. This is interfering with my web searches and banking. This is extremely urgent.

As the title says, I cannot get MP4 files to play in Firefox, which renders several websites unusable. These sites work in Edge just fine, but I cannot get them to work in my preferred browser. Everything is up to date, and I have all the codecs I could ever need installed, as well as the Windows N Media Feature Pack. The browser has been tested several times in troubleshooting mode, and I've even gone as far as running Windows in safe mode with networking to try to isolate the issue. I cannot get it to work at all. This is the 2nd device I've had this issue on, and it's driving me up a wall.

Any help or advice would be greatly appreciated.

I'd like to permanently delete an account that was set up on a former employers email address (email which I can no longer access). Unfortunately I have no secondary email address recorded in the account and all the options on my account page require that I authorise any changes from the email account which I can no longer access.

Is it possible to delete the account?

I have stated this issue once before after trying to find a solution by myself.

My query: https://support.mozilla.org/en-US/questions/1363376

Whenever I boot up my laptop, firefox starts running in the background taking up a lot of memory space and cpu utilization. I have been with ffirefox since I started using laptops which is 7-8 years back. I never thought of switching browser or finding an alternative of firefox until for some months the issue is occurring. Now I am really annoyed to open up task manager every time and close firefox which is running in the backgroud. I have seen nothing unusual in the "about:performance" tab of firefox.

Please help me to continue my journey with firefox.

I need to report a situation which may be of interest to Mozilla administration personnel where a major Canadian corporation is stating inflammatory remarks about Firefox security and is restricting Firefox access to customer online accounts. Not knowing a more direct alternative, I am seeking a contact within Mozilla management through this forum with whom I can privately discuss the situation. Any directives would be appreciated.
