How does one specify which program opens a .zip file after it is downloaded?

Presently, the download functions properly, but when I click on the file, VLC media player opens; have no idea why; how can I specify 7-zip File Manager instead?

Thank you. Appreciate.

Can't move Collections from my old phone to my new phone I have pressed sync BTW it still doesn't appear on the new phone. The photo is the two Collections containing 100 web addresses each on my old phone.

I'm trying to set up a bellsouth.net (ATT) account using the instructions at https://kb.uwm.edu/uwmhd/page.php?id=109671. The account setup flows perfectly until it's time to choose the Authentication Method for the Outgoing Server where the choice for OAuth2 is missing (see pic). Why isn't the OAuth2 option showing up? I'm using the most recent release of Thunderbird. Thank you.

My mother would like to export her very extensive address book in CSV format for safekeeping and eventually for porting it to a new email address. She recently updated to Thunderbird v. 115. I can find help for exporting address books in previous versions. In v115, under Tools, I can only find that a zip file of everything in the profiles directory can be made. Am I looking in the wrong place? Any suggestions besides downgrading to v. 102?

I am using Pop OS, which is based off of Ubuntu.

Somehow I did something, and it made the icon disappear for Firefox. I figured I could easily search the internet and find a simple solution.

I temporarily fixed it last night, but here it is missing again.

I could upload a picture, but I don't see what difference that would make. The dock at the bottom has a spot for firefox, but no icon, literally an empty spot, In the application menu it is a blank spot with Firefox worded underneath.

I have uninstalled, reinstalled, purged, deleted the application data in my user folder..

Just annoying. not a huge problem.

I recently installed Thunderbird on a new computer.I set it up to use my Yahoo account. It does receive emails sent to Yahoo but will not send. Every time i click SEND it asks for a password and always says it failed.

Under settings, there are 2 servers, IMAP and SMTP. Each has a different password, but at one point I made them the same. It does not matter because the outgoing server keeps changing its password to about 20 random letter and characters. At one point I copied these random characters into the clipboard and posted it in after it asked for a password...and it still FAILS.

I am using version 81.0.19 Until I get this fixed it is useless. An annoying thing is that each time I start Thunderbird, it asks for the password...on my previous pc it remembered it. Both machines are Windows 10. Can anyone help?

I download a file. It stops and speaks of a security risk. The website is https, but the file is http. Is there a location I can pre-approve all files from the url to override the objection? Thanks.

TB version: 115.1.0 (64-bit) Windows 10 (corporate laptop)

Fresh laptop, fresh install of TB.

When trying to connect email@example.com (not really my email), TB correctly detects that my domain is hosted at Google, configures IMAP and SMTP for OAuth2, and pops up the window to authenticate.

Instead of an authentication prompt, I'm met with this error:

URL: https://accounts.google.com/o/oauth2/auth?response_type=code&client_id=<CHOMP>aq8lmia8j<CHOMP>.apps.googleusercontent.com&redirect_uri=http%3A%2F%2Flocalhost&scope=https%3A%2F%2Fmail.google.com%2F+https%3A%2F%2Fwww.googleapis.com%2Fauth%2Fcarddav+https%3A%2F%2Fwww.googleapis.com%2Fauth%2Fcalendar&login_hint=user%40example.com

Text: Did Not Connect: Potential Security Issue

Thunderbird detected a potential security threat and did not continue to accounts.google.com because this website requires a secure connection.

I try using the pair feature but each time I scan, I get a page showing "Did you use the system camera? You must pair from within the Firefox app" Even though I did pair from the Firefox app. I have tried multiple times, always the same issue.

"OpenH264 Video Codec provided by Cisco Systems, Inc." plugin will sit in the "will be installed shortly" status forever if you have HTTPS-Only mode enabled. I have been pulling my hair out for the last few days trying to figure out why I couldn't play YouTube or many other sites videos.

Turns out the site that the library is downloaded from has a bad certificate installed: https://ciscobinary.openh264.org/libopenh264-2.3.0-linux64.6.so.bz2

``` Websites prove their identity via certificates. Firefox does not trust this site because it uses a certificate that is not valid for ciscobinary.openh264.org. The certificate is only valid for the following names: a248.e.akamai.net, *.akamaihd-staging.net, *.akamaihd.net, *.akamaized-staging.net, *.akamaized.net

Error code: SSL_ERROR_BAD_CERT_DOMAIN ```

Hi, I desperately need help please regarding Thunderbird Email. I factory reset my computer to get rid of a variety of bugs/slowness etc. I downloaded/printed the support info regarding profiles off the mozilla support site. i followed the instructions and saved my profile. there looked to be two profile file folders. i save them on an external drive. Reset my computer. put thunderbird back on, however the new version of Thunderbird doesnt seem to want to migrate my files back. Im really worried that Ive lost my whole history of emails. I have been with Thunderbird for more than 10 years and saved hundreds of emails in various email folders. Ive tried loading one profile folder, the other, then both and all other variations. ive made new profiles and tried to upload my old profiles and nothing works. I did manage to get a couple of my historical email folders to appear, and some sent items from years ago. But 95% of the stuff i still cant upload. Im not very IT savvy, but i believe ive followed the instructions properly. Is there anything else I can try. are my folders saved in the "server" somewhere that i can access? should i try an use an old version of thunderbird? any advice (in laymans terms) would be appreciated very much :) thanks jackie

I can't setup my email account on a new machine. I have Windows 11 pro

I tried a few times uninstalling Thunderbird and reinstalling. Deleting the Profile in between and restarting. It still gets stuck during set up on checking password.

If i try manual setup and Re-test, i get the message "incoming server already exists" HELP

I'm stetting up a testing environment. It's a closed environment with no access to the Internet when it's in use.

The environment is launched from AWS and consists of an Ubuntu 18 desktop and a Ubuntu Server running Apache. The desktop is able to successfully load the website, but with a cert error that the certificate isn't trusted.

When the Ubuntu Desktop launches, it has a fresh install of Firefox, and therefore all the directories in the users home folder are not yet setup for Firefox, including the database where the root CAs are stored.

I'm am able to add the Root CA certificate into the Firefox cert database AFTER the machine fully boots and I run Firefox for the first time. I'm using the 'certutil' package to do this. After I load Firefox, then add the root CA certificate using certutil, I'm able to load the website without error.

I need to add this certificate to the database with the startup shell script for the machine.

Any help is greatly appreciated. Here's the commands I'm using:

1. copy the CA cert into firefox

export ffcerts=`ls /home/testuser/.mozilla/firefox/ | grep default-release` sudo certutil -A -n "testcert" -t "TC,," -i /home/testuser/certificates/testcertCA.pem -d sql:/home/testuser/.mozilla/firefox/$ffcerts

These commands work perfectly after Firefox is run for the first time. I've even tried adding 'Firefox' (with several different switches) into my startup script without success.

I am on windows 10. My Thunderbird was upgraded automatically from 91.11.0 to 102.0. I've lost all my emails, folders, accounts, and profiles, including Giganews (usenet). I tried re-installing TB 91.11.0 and restoring my profile folder, but I still cannot access my old folders, accounts, or profiles.

What did I do wrong? Is there any way to get back to a working Thunderbird? I have numerous backups of my old Thunderbird profile folder.

52.9.0esr is claimed to be the last version for XP. Unfortunately it is not quite true. It is for XP SP2 ONLY. Trying to install on SP3 ends with the message that SP2 is required. IMO the installer is simply too strict on demanding exact version of SP ! https://www.mozilla.org/en-US/firefox/52.9.0/system-requirements/

I went through the list of versions (thanks Mozilla that they all are still available!) and found that the last version I can install is... version... 12.0b6. https://www.mozilla.org/en-US/firefox/12.0/system-requirements/

And indeed I installed 12.0b6 successfully but I would like to install 52.9.

Starting about a week ago, every time I try to download a PDF file, it opens in a new tab instead of actually downloading. I have to copy the link and paste it into the Google Chrome app to make it download properly. How do I fix this?

These are the permanent download links for the latest Thunderbird EXE installation packages:

https://download.mozilla.org/?product=thunderbird-latest&os=win&lang=[LANGUAGE] https://download.mozilla.org/?product=thunderbird-latest&os=win64&lang=[LANGUAGE] https://download.mozilla.org/?product=thunderbird-beta-latest&os=win&lang=[LANGUAGE] https://download.mozilla.org/?product=thunderbird-beta-latest&os=win64&lang=[LANGUAGE]

I found them here https://ftp.mozilla.org/pub/thunderbird/releases/latest/README.txt and here https://ftp.mozilla.org/pub/thunderbird/releases/latest-beta/README.txt

Are there any permanent download links for the latest Thunderbird MSI installation packages?

If not, I recommend creating: https://download.mozilla.org/?product=thunderbird-msi-latest&os=win&lang=[LANGUAGE] https://download.mozilla.org/?product=thunderbird-msi-latest&os=win64&lang=[LANGUAGE]

I just completed changing the storage location for Thunderbird email messages, from AppData/Roaming to a new Thunderbird folder under Documents. This was to ensure that my computer quick-backup utility would save emails. I followed Mozilla instructions and all went well, everything seems still to work just fine, except that one POP email account shows nothing in the appropriate Thunderbird Inbox now. Sent messages show up, and new incoming messages to that account go into the Inbox and show, but all the old ones from before the location change just don't populate the Inbox listing area. The Inbox file at the new location has messages in it, I can see and read them with Notepad, but there's no corresponding Inbox message list for that one account. What could have gone wrong, and is it possible to somehow 'activate' the old messages so they show, or move them again from the original AppData/Roaming location to the new one? Thanks!

I did this many years ago on an old PC but don't remember how. I have a new laptop and I'm trying to import my Outlook PST archive to TB. It contains 30 years of important emails. I'm trying to get away from MS's Office - it's become too expensive.

I tried to use TB's tools>import>import from Outlook but I get an error message saying "no profile is found".

Can I do this within TB or do I need a 3rd party app? If so, is there a reliable one?

Thanks in advance.
