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?

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.

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 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!
