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.

Hello,

We have a client using Azure Virtual Desktops. Most of the users prefer to use Firefox. We are having an issue that anytime we update Firefox and reimage the virtual hosts. When the users login they get a new Firefox profile. We have to remote in and copy their old profile data to the new profile.

Is there a better way for us to handle Firefox and profiling in and Azure Virtual Desktop deployment?

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

Once you add a new account, you have to race to open up the settings and turn off the "Download all mails" setting that is hardwired as the default. Even after having done that, I am left with GB of copies of mail messages that I don't want to store on my local system.

How do I get rid of those local copies? Compacting doesn't seem to do it - there's no "Compact now" button in any case. I don't know what "when it will save over N MB in total" means, exactly. Save compared to what? Now 50% off!

Likewise, if I have Message Synchronizing (Keep messages in all folders etc) turned off, but Disk Space - Synchronize all messages locally regardless of age is still selected, is it going to download copies anyway or no?

If it will download anyway, or if it already did download, if I change the Synchronizing setting to "only the last 30 days" will it remove the older local copies? When?

The only "recover disk space" option deletes both local copies and originals on the remote server.

There really should be a "purge local copies" action available in the client. It may be that it is OK to go out to the OS and remove certain files myself, but maybe it won't be in the future. Every note that is about "Simply open a Terminal window..." describes specific files that don't quite match what I see here in May of 2024 on a Mac. But the tool itself knows what can be removed safely.
