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?

I've been happily using Thunderbird for email for many years. Recently, the gmail OAuth2 requirement has made my POP3 accounts quit working. Currently on 38.5 for Windows 10.

Following various posts, I've tried to convert two specific email accounts to imap, and things are not going well.

My primary email is already imap and works fine. I've tried multiple times to convert the other two, and my current state is I've deleted those two accounts entirely (via Account Actions). When I try to install Existing Account, I eventually get to the point where the server config seems correct, but hitting "Done" results in the above message. I'd be surprised if imap.gmail.com can only support one email address. The emails are named differently, and use different passwords. Imap is enabled via browser based access to both accounts.

Incoming server imap.gmail.com:993 Outgoing smtp.gmail.com:465

"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 ```

OS: Fedora 36 Firefox Version: 104.0 (64-bit)

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.

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

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.

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

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?

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.

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 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.

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 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?

Starting today, I went to download a .pdf file to open automatically with Adobe Acrobat as I usually do. However, this time I got a pop-up from Microsoft Word stating, "Word will now convert your PDF to an editable Word document. This may take a while. The resulting Word document will be optimized to allow you to edit the text, so it might not look exactly like the original PDF, especially if the original file contained lots of graphics."

I went to Settings - General - Applications, went down Contents list to Portable Document Format (PDF), and tried the various settings under the Action column, to include "Save File," "Always Ask," "Use Acrobat Adobe 2020." None of these worked or made any difference. I open numerous .pdf files every day and I need to be able to just click on them in the website and have them open in my Adobe Acrobat program - as they have up until today. What do I have to do to fix this? I am using Version 102.0.1 (64-bit).

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!

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.

Why has this started up again? Pdf files are automatically downloading to my computer when all I want to do is look at the file. So many files that now need to be trashed after looking at them. This problem has happened in the past, but was resolved, only now I am finding it happen again. I do not want to have files saved unless I want to save them, not Firefox deciding that any file I open should be saved. I have Windows 11 & Firefox Version 113.0.1. Is there a way to revert to an older version of Firefox?

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.
