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.

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?

"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 ```

Most of my old mails are stored in a MBOX file (previously gmail). I would like to import them. The import/export NG tool is not compitable with version 115. Any other add-on doesn't work. The normal import function of T-bird can't handle a MBOX file directly. Importing the zip won't work. How can I get my old mails imported?

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.

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.

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'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.

Hi there!

I'm attempting to migrate my Firefox (106.0.3) profile from the Linux Mint V20.3 on one SSD to a new installation of Linux Mint V21 on a separate SSD. I'm using the information supplied on this page:

https://support.mozilla.org/en-US/kb/back-and-restore-information-firefox-profiles

Step 4, under Backing up your profile says: Right-click on your profile folder (e.g. xxxxxxxx.default), and select Copy.

This folder, qspfoqtl.default, contains 1 file, named times.json, the contents of which are:

{ "created": 1618792039414, "firstUse": null }

Clearly, not my Firefox profile.

There is, however, a folder named nnob5aww.default-release that contains a bunch of directories and files (505.4MB) with names like bookmarkbackups, browser-extension-data... storage, weave.

Is this documentation incorrect as of this release of Firefox? And, should I be using the nnob5aww.default-release folder as the profile? I'm a little confused. (Most often, I'm a lot confused.) Any help would be appreciated.

Thanks in advance,

- Ralph

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.

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.

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.

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.

Hello, I recently got a new Android phone. On my previous Android phone I used Firefox without creating an account and saved hundreds of bookmarks. I would like to move those bookmarks to Firefox on my new phone. Please tell me how to do this. Thank you!

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.

I have set the synchronization target to be 90 days inside the account settings.

Upon compacting the folders and restarting thunderbird, the messages outside of that range is still in their respective folder.

Is there a way for me to delete the ones out of range, but keep a remote copy on gmail?

Dear community,

As I use a few self-made unsigned add-ons, for several years now I have been using the Firefox unbranded builds on Linux with great joy. In the past these became available for download shortly after a regular Firefox was released. Lately though things have changed. The current latest release for unbranded is stalling at version 107. So it's getting further and further away from the official Firefox, which is at 109 at the time of writing.

Obviously I'm concerned my unbranded Firefox is not getting the same security updates any longer. I do realize there's alternatives for supporting unsigned add-ons. Running a Firefox nightly or developer-edition is something I'd want to avoid, so for me these aren't real alternatives. I've also tried tracking unbranded info on bugzilla.mozilla.org, but couldn't find anything relating to this 'lag'.

Where can I find more info on this topic? Are these unbranded builds being discontinuated?

Thanks for reading, keep well!

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

on debian live:

$ uname -a Linux debian 5.10.0-18-amd64 #1 SMP Debian 5.10.140-1 (2022-09-02) x86_64 GNU/Linux

I am running: $ thunderbird --version

Thunderbird 91.13.0

to download all the data in my gmail account via POP3, but Thunderbird seems to be making assumptions about where to put your data and I haven't found a way to tell it where to put it; so, since it uses the user's home directory, the only way I think you could easily put the data where you want is by changing it, but I can't:

$ usermod --move-home --home "${_NEW_HOME}" "${_WHMI}" usermod: user user is currently used by process 1141 $ sudo ps -aux | grep 1141 user 1141 0.0 0.1 15600 9144 ? Ss Nov05 0:00 /lib/systemd/systemd --user user 50636 0.0 0.0 6244 712 pts/0 S+ 06:42 0:00 grep 1141

Unless they both try to exclusively access /etc/passwd, I can't understand how /lib/systemd/systemd could possibly relate to usermod.

Why is it TB doesn't have --data-type (POP3 or IMAP, ...) and --data-dir options you could enter in the command prompt at start up?

I am hacking my way around to be done with it. I am sure you have a very solution to my kind of problem. Any suggestions?
