Firefox stopped working on my computer. Every time I try to open it I get an error message that says "Windows cannot access the specified device, path, or file. You may not have the appropriate permissions to access the item." I tried to uninstall and reinstall with no success. Our IT dept tried as well and nothing we have tried has resolved the issue. Thank you for your help.

For some time I cannot access any more Gmail messages from my Thunderbird.

When cancelling my email address in Thunderbird and trying to reopen it as new address, I'm getting the message "registration on the server failed".

Then I tried to open my email address on the laptop of my wife in her Thunderbird: there it works perfectly.

In addition I tried to open her email address on my Thunderbird: I'm getting the same message "registration on the server failed".

We have both Thunderbird 128.12

I'm working with Windows 11.

She is still on Windows 10.

Any ideas?

Thanks!

Hi,

Not sure if anyone else is reporting this but ever since the last update - 140.0.2 Firefox Release, June 27, 2025 - many of my general sites, yahoo, news, company sites that I use everyday, do not load. I have to use Private Browsing, keep refreshing or change URL for the site to load. Anywhooos, I do appreciate you guys! keep it up!

Am getting this message along with a recurring download of a specific email (keeps coming back even after deletion) that does not allow any other new messages to be downloaded. I do see new emails on my phone but will not read into Thunderbird??

Error: "Unable to write the email to the mailbox. Make sure the file system allows you write privileges, and you have enough disk space to copy the mailbox."

Tried: Troubleshooting, closing Thunberbird and reopening, rebooting windows system, compacting, etc. to no avail....

Hello,

I have no idea who is going to read this, but I was in my Cell Phone companies’ site today and got an error message that Firefox would not show the bill details. Some stupid thing about other web sites and sealing my information. I needed that page and could not see so I had to use another browser (not Chrome or Edge) to get the bill to display.

I then had a coupon to print from an e-mail from my Pharmacy. Again you gave an error message but did download the coupon to where I save things.

I do not want to use Chrome or Edge as they track the S**t out of you. I have another that is laid out like Chrome but supposedly isn’t and I use that. I have to pay for that one. The main thing these browsers don’t have is the Menu Bar at the top and you cannot put it on. I use that to free up screen space that is lost the way they do things.

Can you PLEASE get things right in Firefox so I don’t have to waste my time or worse have to use this other browser I hate.

Ever since the most recent firefox update, my screensaver doesn't appear after laptop has been idle. According to the Mac Activity monitor, Firefox is blocking it. I've tried quitting Firefox and restarting, and also restarting laptop, but no solution.

Bonjour, Thunderbird a interrompu la connexion d'un compte email Orange d'un ami. L'adresse et le mot de passe de messagerie sont corrects (ils permettent d'accéder au compte en ligne). Thunderbird n'arrêtait pas de demander le "nouveau mot de passe" et le rejetait constamment. Nous avons d'abord essayer de supprimer, puis ajouter le compte. Cela n'a pas marché. Nous avons désinstallé puis réinstallé Thunderbird. Puis, nous avons tenté d'ajouter le compte (avec protocole IMAP 993 SSL/TSL mot de passe normal et 465 SSL/TSL mot de passe normal). Cela n'a pas marché. Nous avons redémarré l'ordinateur à chaque fois. Que pouvons-nous ou devons-nous faire? Merci d'avance. Cordialement, Hélène RF

Hello, Thunderbird has interrupted the connection to a friend's Orange email account. The email address and password are correct (they allow access to the account online). Thunderbird kept asking for the ‘new password’ and constantly rejected it. We first tried deleting and then adding the account. That didn't work. We uninstalled and then reinstalled Thunderbird. Then we tried adding the account (with IMAP 993 SSL/TSL normal password and 465 SSL/TSL normal password). That didn't work. We restarted the computer each time. What can or should we do? Thanks in advance. Best regards, Hélène RF

Hi,

 Only in Firefox on my windows 10 pro pc do I have to keep on signing into Homedepot.com with a security code?
 So I looked up the problem and one of the solutions (I tried a few) is to clear the old chache and cookies?
 Trying to do this.... get link after link after link.....after link.

How do you do it?

  Wish I can upload something... but can't upload what you can't find?

Thanks, Julio

I am trying to use Firefox and when I click on the Icon nothing happens. I run it as Administrator and the browser open but I can not load any web pages. The only web browser that works is Duck Duck Go. Google Chrome does not work either.

Hello -I am having problems opening files in thunderbird -I keep getting '"This file does not have an app associated with it for performing his action. Please install an app or, if one is already installed, create an association in the Default Apps Settings page." I have uninstalled and reinstalled t/b several times but nothing works -any solutions please. I cannot even open 'help' on my desktop - I am using another computer to write this

I play a video game and it has a /wiki <thing> chat command that is supposed to open my browser tab to a search result of <thing> on that games wiki website. Firefox has stopped doing this. I can not find, or figure out, what settings to change to allow this to work.

I have been trying changing cookie settings and Firefox will have a pop about it already running, but not responding. I click cancel because Firefox seems to be working fine other wise.

Does anyone have any idea what I can do?

I am subscribed to a mailing list from Wordsmith.org, and I get an email with a different word each day. See today's example below:

iteroparous

PRONUNCIATION: (IT-uh-ro-PAR-uhs)

MEANING: adjective: Reproducing multiple times in one’s lifetime.

The email has a link to an mp3 audio file with a voice recording of the proper pronunciation. Today's word: https://wordsmith.org/words/iteroparous.mp3

The file omits the first part and says "____perous". It is not just this one instance, it is all the time, every day. Chrome also has the same fault, but Microsoft's Edge plays the mp3 completely, as it should.

Hello, all. My first post here. My problem is that: When I'm done using Firefox and close the app, several copies remain and need to be closed separately. It's a minor annoyance, but I'd like to fix it. Any suggestions? Thank you.

you have mager problems with with your fire fox system i have trouble with video links to chat but i don't have any problems using google chrome but it does not have the memory back like your site does i think it might be to do with your software updates i cant find any other logical reason for this problem
