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?

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

Thunderbird 115 included in 24.04 LTS installation.

My profiles are located on the SD card working well on other two laptops running ubuntu 22.04. Swap SD cards between two laptops is my way of working with Thunderbird since 13.04.

After installation 24.04 LTS (and Thunderbird 115 included). Following the instruction for adding old profile to the new Thunderbird. Help->thunderbird information->about:profiles. Creating new profile. 1) Using the function CHOOSE FOLDER indicated the path to the profile /media/VB/AB49-E208/Thunderbird profile 2) The path to the folder shown by Thunderbird is different (and strange): /run/user/1000/doc/58235/Thunderbird

When looking into the directory tree the folder is empty (obviously). Thunderbird therefore cannot reach the profile located on SD card and doesn't work.

QUESTION: Is there any way to overwrite the profile folder path in Thunderbird 115 ?

Hi there. I wiped my C Drive and reinstalled windows 11 on my PC. Completely from scratch.

The first few thing I did is download firefox. I believe in the first boot of firefox, I can download things fine, I installed Ublock Origin add-on and a few installers for the app that I need to use. I can't recall when, but after a few reboot, I noticed that Firefox can't download anything, every download link I click on, the download fail instantly, I can't install add-ons as well.

I tried reinstall firefox, changing download folder target, nothing helped.

Can you take a look please? Thank you!

Hi when i have to download my bios updates i am being forced to use misrosoft edge or chrome none of which i use , so the question is can i use firefox safely thanks . Lee
