Is there an easy way to downgrade back from the beta channel to stable? The downgrade protection feature seems to be a major blocker of just installing the latest stable version. Noticing high RAM usage on Firefox 100 and crashes which is making it hard to use for a daily web browser.

Hello, since migrating from Chrome to Firefox, I have used the Import Wizard to successfully transfer over my bookmarks and history, but I just can't seem to get my logins/passwords over. The wizard finishes saying that it successfully imported saved logins and passwords, but nothing shows up in the password manager. I am running Windows 10 64bit and Firefox is up to date. Anybody have any suggestions?

Thanks

Every week, for work, I need to download at least one large video file from Microsoft OneDrive and then upload it to YouTube. (These are MP4s in the range of 200 - 800 MB.) For the last couple of months, maybe longer, the download keeps failing in Firefox. When I switch to Chrome, the same MP4 downloads with no problem.

Any idea what might be going on? Usually the file starts downloading just fine; I see the bar gradually filling up in the notification area, but then it suddenly stops and says "Failed." If I retry, the same thing just happens again.

I'm not using any kind of download manager (that I'm aware of), just relying on Firefox's default download behavior when I click on the "Download" link on the OneDrive web page (sample URL: https://olucdenver-my.sharepoint.com/personal/YADA_YADA/_layouts/15/onedrive.aspx?id=LONG_QUERY_STRING_HERE).

Thanks in advance for any help you can provide!

I've always used the "Always ask you where to save files" option when downloading. Recently (beginning of April 2022), files go directly to the Downloads folder. The "Always ask" option is still selected in Settings.

I've tried un-selecting and re-selecting, restarting Firefox, restarting my computer - basically every iteration of 'turn it off and on again' that I can think of.

When you go to preferences>Privacy & Security and you click on Learn more about the privacy issues of remote content (or any other further information which is in a blue font) you get a page that says Secure Connection Failed When you run diagnostics you find that Google Location Service Key and Mozilla Location Service Key are missing Please tell me how to resolve these 2 issues

Hello,

Whilst helping a friend recover data after she killed her laptop, my Windows 10 will no longer boot.

I have tried the steps in various posts to move my profile to another TB installation without success. The version number on the crashed machine is 68.7.

Can anybody suggest how to recover my email? The only thing I can see when I move the profile is some of my email account names, but none of my local folders.

I hope to fix the crashed PC, but I need access to my past email.

I am looking for a new email service provider, and Proton mail seems to always be near the top of the list. Searching Thunderbird support yields only help from a year or more ago. How well do proton and Thunderbird mesh currently?

I need help importing Outlook 2007 data into the current version Thunderbird. I was able to import the data into Thunderbird Version 31.8 but when I go to Help | About Thunderbird it says it's the current version and there is no upgrade to current link.

I copied all the files from the V31.8 profile to the v91.8.1 profile. I then deleted Thunderbird installations, installed v91.8.1 and launched. TB launched and has been trying to do something for the past several hours.

Thoughts?

My PC crashed and lost most programs including Thunderbird. I am logged in to my account and downloaded and installed the program. However in the "Set up your existing email address" I get an error message.

I've read all the articles here about importing my passwords and history, but the Import Wizard is ONLY giving me the option to import my bookmarks. Even if I can't get the browsing history I need to be able to migrate my (extensive) password list.

I've exported my Safari passwords as a .csv file, but there doesn't seem to be an option to import a .csv file.

The page here regarding it says the feature is 'disabled by default' but does not say it's unavailable and I can't find clear instructions for how to activate the feature so that I can import my passwords. Can anybody help?

Cannot download Thunderbird.

The page [https://www.thunderbird.net/en-US/] has no download link. The page [https://support.mozilla.org/en-US/pro.../thunderbird] has a "Download" button but that just takes me to [https://www.thunderbird.net/en-US/] which has no download link.

I have spent a considerable amount of time looking at every page I can find, and there is no download link anywhere.

Apparently, I need some sort of telepathic powers to find Thunderbird, or, you just really, really don't want anyone to use Thunderbird.

I don't get it. (Literally and figuratively)

Thank you Stan and David for your replies which were helpful but unfortunately I didn't express myself clearly enough for which I apologise.

My USB Thunderbird back-up is from a LENOVO Laptop. The Thunderbird version is 91.2.1 (32 bit) running on Windows 10.

I have new DELL Inspiron with Thunderbird 91.8.1 (64 bit) running on Windows 11. I have successfully found in Mail -

• Local Folders which contains .msf Filter Rules DAT folders for Trash (File), Trash.msf (MSF File), Unsent Messages (File), Unsent Messages.msf (MSF File)
• pop3.iprimus.com.au folders for Drafts, Drafts.msf, Inbox,

Inbox.msf,
.msg FilterRules,
.popstate

Sent Sent.msf Trash Trash.msf

In the LENOVO back-up Thunderbird there are no matching like named folders or files to input into the DELL. nor are there any storage files with the extensions (mbox) or (sbd) folders.

SEPARATELY when I initially setup the new DELL I put the back-up USB is port and Thunderbird initial set-up provided a command to load data from that drive which worked ! In that case I selected the top option IMA ?which stored data on the cloud based server ? not the POP option.

What led to this major issue was a need by DELL to delete and repartition the SSD to resolve a problem which I discovered with AVAST and resolved. It was one of these parties that suggested that Thunderbird would automatic convert the old files and set-up appropriately. In all there were 6 individuals involved in at least 2 countries. I have spent countless hours on this new DELL PC with Windows 11. My time is quite stretched hence my delay in responding to your good responses.

Hopefully there's some additional info here which will help resolve the problem of retaining all msgs, folders and addresses.

Thanks again for your time in considering my problem and providing possible solutions.

I set up a new Dell 5510 Inspiron with the latest version of Thunderbird which runs well in Windows 11 environment. Previously when I set up a new PC I followed instructions which created a backup from the superceded Windows 10 Laptop on to a USB file Mozilla Thunderbird. I installed Thunderbird and compared the files and discovered 1 file which had no data in it and copied that data directly into that file and it worked perfectly - bringing across everything contacts, folders etc.

On the new DELL I followed the setup prompts and had no success - I activated the top box to store data, not on cloud but to retain on server. I uninstalled and tried again this time activating the box under the top one to store most historic data on Laptop - again no success. - comparing data was fruitless as there was no file with 0 data

It has been suggested that (with Thunderbird closed, I just copy the Back-up USB Folder "Mozilla Thunderbird" from the Window 10 Laptop over the "Mozilla Thunderbird" in Apps under Settings in Windows 11 and magically all (Contacts and email history in folders ) is supposed to happen. Reason is that the new Thunderbird App does all the conversion and set-up.

reluctant to do this as it's taken 2 weeks to reach this point and I don't wish to over-write those Thunderbird that have been received in that time.

Your advice would be appreciated. I the process as it has been suggested above OR is there another process to be followed ?

Thanking you in anticpation of your time to digest the above and respond accordingly.

Some how Yahoo jumped in and displayed a yahoo Home page with no way of deleting it. I tried installing Firfox..But it became stuck half way..what should I do to get back to Firefox ?

I have a MacPro which runs three different OSes. I want to boot to any of them and be completely current with my email, so the goal is to locate the Thunderbird Profile to a neutral, non-boot drive that is always available. I have an internal drive in one of my drive bays that is perfect for this. I tried to follow the directions for changing the "profiles.ini" file on my current boot volume, but even with that done, it still makes a new folder. I just want Thunderbird to quit referencing the old location and start referencing the new one. I thought I had updated the "profiles.ini" properly, and, having deleted the actual profile folder within the Profiles folder inside it, it still wanted to create a new one with all the default stuff empty. So it obviously was not looking to the Profile folder I had copied earlier to the neutral drive, even though I put the path in the .ini file and changed the path under [Profile0] and set IsRelative to 0. Should I also have changed the path to the [Install712DAF5A23ABECDC] portion of this .ini file to the new one and unlocked it?

Is there a way to ALSO have the "profiles.ini" file and all the apparatus around it on the neutral volume so that EACH version of Thunderbird, no matter which OS is currently booted, accesses this info from there?

I wish this kind of instruction was explained better.
