Hi guys.

Need some help. I can't download any files using Firefox. It always says, "Failed".

I tried other browsers, and I'm able to download just fine.

I already tried this guide, https://support.mozilla.org/en-US/kb/cant-download-or-save-files, but still same.

I haven't tried to re-install Firefox because I have a bunch of workbook marks that might get lost. So, I want the re-install option as a last resort.

Thanks~

Hello,

James here. I CAN NOT find the Firefox application file location. There is no option to show file path upon right click of the desktop icon and I can not locate it in File Explorer. I have done an entire (C:) drive search and turned up nothing. C:\Users\(username)\AppData\Local\Mozilla Firefox does not exist in my file system. I am at a loss here and it's driving me bonkers!

I get bad request from the official Mozilla repo: Err:8 https://packages.mozilla.org/apt mozilla/main all Packages

 400  Bad Request [IP: 34.160.78.70 443]

Did the URL change or smth?

Hi there,

On the 23. of Mai I first noticed that I am unable to download any files whatsoever. I tried downloading .exe files and also a .csv file. When I try to download one of these files it appears in the downloads window but immediately goes to the status "Failed". Any retry fails as well.

The same thing goes for extensions. I cannot download any extensions or plugins using my Firefox browser. Since I reinstalled Firefox I can now also not use Plex because Firefox can't install the required plugins.

I will attach screenshots of all the errors I get.

All of the above worked when I tried it on the Edge browser.

Firefox version: 126.0 Windows 11

Things I have tried to fix the issue:

• Use the network connection from my phone instead of my home network
• Disable firewall and windows defender
• Reinstall Firefox
• Refresh Firefox
• Downgrade to version 125.0.1 and 122.0
• Reset router to factory settings
• Flush dns
• Restart PC
• Manually delete profile folder
• Delete temp files
• Change download destination
• Disable "Block dangerous and deceptive content"
• Troubleshoot Mode

Is Firefox using some other temporary folder for downloads?

Any ideas on how to fix this issue would be appreciated.

Thank you.

I've gone through most of the questions asked regarding this and have tried to follow all of the directions but none of them work. Let me begin by saying this is the worst time I've ever had at migrating from an old computer to a new computer using TB ever. EVER! This is the worst. I am moving from an ASUS Win11 to a HP Win11 so there shouldn't be that much of a problem. I've done this more than a few times so I know the drill of copying the %appdata% from one place to another. I have installed uninstalled deleted reinstalled, uninstalled reinstalled deleted three times and keep getting the same problem and have been doing this going on three days. I donated to get his copy and am about to ask for my donation back if I don't get a very simple answer. I keep getting that error message no matter what I do. I need a very simple walk through on how to get what I am able to save from the old computer into the new computer without a lot of magic and rain dancing and click here and delete this and see if this sticks. I need a very simple take your profile.zip and unpak it here then open TB and do this. PERIOD. The profile is on the same computer not a server. If I cannot get a quick down and dirty answer please just tell me and I'll ask for my donation back and move to MS outlook and deal with their FU'ed POS. I really don't know why TB has taken a turn for the worst here. But it's not looking good IMHO.

I am running 115.11.0 on Ubuntu 22.04

I changed email SMTP servers, incoming and outgoing. First I migrated IMAP on the cloud between old host and new host. I connected Thunderbird using existing a profile, just changed server information. After that email started coming into Thunderbird. I discovered a bunch of the filters had been disabled with no destination folder. Not all of them. Just maybe half. It knew the destination folder for the filter because it was at top of window when I would look at filter rule. I had to use that as guide as to what destination folder it should go to, and it filters fine.

Why were all these filters cleared of destination folder?

No idea what the cause is but I cannot download ANYTHING on my browser for some reason. Pictures, documents, executables, browser extensions. Tried downloading documents from email attachment.. fail Tried downloading VLC... fail Tried every default recommended solution, clean install, you name it. Mind you all of these files downloaded just fine perfectly via Microsoft Edge.

Noticed another abnormality. Changed the download folder to a custom one. Download failed and DELETED the folder for some reason.

Two-factor authentication helps protect your account if someone else tries to log in. When there's a login from a new device or browser, we'll ask for a login code or other verification method to confirm that it's you. You'll need to set up two-factor authentication to keep using Facebook.

I usually download and install manually the custom install of Firefox on Windows.

Recently, a new version was automatically installed without my permission and destroyed all my customization. THIS IS UNACCEPTABLE. I had to restore the older version from backup and I was going to stop updating.

But I see that the manual custom installation is still available for download.

I want to make sure that if I use it it will not wipe out my customization again.

Please confirm.

While following this step in order to reduce CPU and memory consumption of firefox [content-prefs.sqlite file], I accidently deleted the Profile folder itself.

After this firefox wasn't opening and was stuck on not responding in activity monitor.

I reinstalled firefox, multiple times even after a shutdown, removing any old files in the Library folder. Still it's stuck on the same issue, firefox doesn't opens up even once.

my windows 11 was crashed and browsing was not working so i repaired my window, thunderbird lost all profiles and data from the program but all the emails and folders names i had are visible in local directory, so i tried to setup new account and then change local directory to my old directory. i did this few times before and it worked perfectly but now this method is not working and only handful of emails imported i need help and solution, these are years of emails and very important last few weeks important emails are missing

I am in the process of migrating to a new Windows 11 PC. I am a long-time user of Firefox and have version 126.0 - 64 bit on my old PC. On my new PC I apparently downloaded it from the Microsoft Store during all my software installs. That version shows as "Windows MSIX Package Mozilla – MSIX – 1.0”

Are there differences between the 2 versions and should I do anything such as reinstalling from Mozilla?

Thanks, BillT

I need to migrate the complete profile (all settings, bookmarks, passwords etc) from a snap install to an apt install on the same system. Currently I have both versions installed, but i want to remove the abomination that is snap..

I tried copying ~/snap/firefox/common/.mozilla/firefox files to ~/.mozilla/firefox but that doesnt seem to work. Since this is a multi-user system i dont want to rely on mozilla accounts to sync everything to the cloud.

What do i need to do in order to migrate all the data from one install to another?

Unable to access HydroOne.com website. Get error message - Service Unavailable HTTP Error503. Only happens with Firefox browser.

A computer is still running Thunderbird 102 happily. That is the plan -- the user is NOT prepared to deal with 115 and later, and the changes therein. Somehow, even though it was supposedly set to only install updates when you told it to, it downloaded and began the process of installing 115. So it's up and running now at 102, but says that when you restart, it will go to 115. Please don't tell me how wonderful 115 is; been there, done that, it's not my machine but it's someone near and dear to me who detests computers in the first place but has to use them so gratuitous changes are utterly unwelcome....

So is there a way to delete something and tell Thunderbird to just keep running 102 and not do the upgrade? If I have to reinstall 102 on top of the old profile, which contains many gigabytes of IMPORTANT mail, I can deal with that. I assume that the profile hasn't been munged yet by the update so I'm asking now. Thanks!

Hello! I have tried to install the normal Thunderbird on my PC for months now. Everytime all it does is count more and more files, folders etc. I can't get it to install. The two screenshots were made within a few minutes. I let it install for around an hour one time and it simply counted more and more files without ever moving in progress. I really don't know what to do. Restarts, redownloads, nothing works. Maybe someone knows what's wrong. Thanks!

After recent update to Thunderbird 115.11.0, I can't send emails through my hotmail smtp server.

Error message: Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) smtp-mail.outlook.com timed out. Try again.

I read the Thunderbird update for 2024 information that recommends changing Normal Password to OAuth, but OAuth is not an option on the drop down list of methods. (see attached)

How do I fix this? Thanks

I've been getting error messages when I send emails using thunderbird about server timing out. As a last resort I tried removing all accounts, and just set it up again. But then I started getting the error message during manual configuration step "Thunderbird failed to find the settings for your email account". I've already tried creating a new profile I'm still getting the same error.

here's the manual configuration I'm working with Incoming: IMAP, port 993, SSL/TLS, Normal password Outgoing: port 587, STARTTLS, Normal password

our team uses GoDaddy for email domains - not sure if that's relevant or not. other teammates have been able to set it up successfully. Same configuration, account and password.
