I downloaded. I donated. Then a screen come up with an envelope and some love hearts saying "one more step". But there is no indication as to what that step is or how to take that step! How does one install this program?

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~

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 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.

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

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!

I'm having problems with the Cardbook add-on but it is up to date based on my version of TB. When I go into Preferences->Advanced-> Update 'Check for Updates' shows I'm up to date. However, when I check archived versions it looks like the last version that worked with a MAC release of less than 10.12 is 78.14.0.

I'm confused if I can upgrade to 78.14 and how I would do it?

Thanks for any advice

P.S. and yes, it's a very old Macbook from 2009.

I am posting this on my Mac Monterey; but the problem is on my Windows 10. It is similar to my last post about Firefox on that system. Updating is hanging. About Thunderbird shows an update available, just as that feature on Firefox did last week. However, though it indicates that it is attempting to download, it shows that nothing is downloading. So, there is a spinning icon on the left, but zero bytes downloading, just as Firefox did. After a restart last week Firefox applied the download. The same action occurs now with Thunderbird. To contrast, that same update just downloaded and applied on this Mac Monterey. The version on Windows 10 is 115.10.2, 64-Bit. There is a general Windows Update problem on that system. Edge, on the other hand, downloads its updates without any problem. I just ran a Troubleshooter that Windows makes available under Settings, Update and Security, Troubleshoot. Right now I am about to restart that computer.

This is my Mac Monterey. My Windows 10 is in Safe Mode With Networking. The last update will not download. That version is 125.0.3. What's available under Windows updates does not download either. Now I am running my antivirus on my Windows to see if it runs clean. I do not know why I cannot apply these updates.

Had all my emails stored locally. Accidentally uninstalled Thunderbird. Reinstalled. Unable to Import my old settings from my "profile". Error message says "Unexpected error" Was able to import configuration alone, but it was all wrong. Can't set up my gmail account. Error message "Malformed server" Please help

Firefox only offers seven filetypes for handling (open or save the file). How can I enter more, for example what to do with an xlsx file? I want Excel to open the file, not download it.

I am migrating from Thunderbird to Office 365. I have moved the email by putting the Gmail details into Office 365. However could you please advise how I can migrate Tasks , Calender and Contacts from Thunderbird to Office 365 without having to pay for an Mbox to pst conversion tool.

This is the error while trying to download Microsoft Office application "Office Timeline" "\??\C:\Program Files(x86)\Mozilla Firefox\firefox.exe." Cannot start or run due to incompatible with 64-bit version of Windows
