Have been using the 104.9.0esr 64-bit release on Windows 11 for some time now (mostly for email, involving a number of email accounts) and have been generally satisfied...

...but discovered when I started looking into switching over to the 145 default release that I have a capital-P Problem. The first thing recommended on making that change is - sensibly - to back up one's Thunderbird profile. Only as far as I can tell, I don't *have* any such file anywhere on my system. [To answer the obvious question - yes, I've got "View" set in File Explorer such that it should be showing me hidden files.]

I have drilled downward through all the USERS subdirectories on my C: drive. "Default" and "Public" have nothing at all (as one might expect). My personal subdirectory has a Mozilla directory under "Roaming", and both a Firefox and a Thunderbird directory therein, but the only things in the Thunderbird directory are an empty folder labeled "Crash Reports" and a tiny "desktop.ini" file.

There is a "Mozilla Firefox" directory under Program Files, but nothing in that hierarchy looks applicable. There is a "Mozilla Maintenance Service" directory under "Program Files (x86)", but nothing there appears relevant. There is a "Mozilla [alpahnumeric hash]" subdirectory under "Program Data", but nothing there appears relevant.

And in fact, I begin to think I have a bigger issue than I thought I did...because the more I poke at my C: drive, the less I'm seeing...to the extent that I'm not at all sure where the Thunderbird program itself (not to mention a quite large accumulation of associated email) is being kept.

Which would be nice to know if one were attempting to back up one's mail before changing program versions....

Hello, this is AJ, I was thinking of signing up again but had a question.

Could you please tell me if your VPN service will work with YouTube TV? I'm trying to watch my local MLB team game through another US State or Country.

Thank you

A windows update occurred this AM 04/15/26 and it has affected my browsing. Don't know if this update effected my G mail. My U tube profile changed form browsing to history. example: when I click on to my U tube profile it brings up the last view I was browsing. I cannot refresh Firefox like before from the help menu, of which would select the profile I desire.

My email storage server has a limited space allocation. Because I keep most emails for future reference/recall, I have been moving important emails to specific folders I have created in LOCAL FOLDERS. The LOCAL FOLDERS resides in a local drive in my main desktop computer.

Lately I switched from POP to IMAP so I will be able to access my emails on my phone, remote desktop at home & on my notebook when I travel.

Because of limited storage space allocation, only the main basic folders (inbox, drafts, sent, junk, trash, etc........) reside on the server & appear on all my connected devices (phone, remote desktop & notebook).

When I am on the main work desktop, everything works flawlessly. I have access to whatever information I need. However, when I am on the other devices, all I see are the basic folders that reside on the server.

Could you suggest a creative way I could take the LOCAL FOLDERS along with me when I am outside the office? I was thinking of mounting the LOCAL FOLDER in the cloud, if that is possible. I will be the only one accessing it (single user) so colliding versions should not be an issue. I was thinking of copying the files on to an external drive then restoring to whichever device I use but the problem with this workaround is syncing back to the main machine.....a lot of extra work & steps.

Any suggestions? Hope to hear from someone soon. Thank you.

Whenever i try to connect to any site, it fails to load and displays the following error message:

This web site requires a secure connection. - The page you are trying to view cannot be shown because this web site requires a secure connection. - The issue is most likely with the web site, and there is nothing you can do to resolve it. - You can notify the web site’s administrator about the problem.

When i press 'advanced' it says: [Site name] has a security policy called HTTP Strict Transport Security (HSTS), which means that Firefox can only connect to it securely. You can’t add an exception to visit this site.

This happens on every site i try to visit. I am on a samsung phone running android version 15. Other browsers do not have this problem (i am sending this from opera), and firefox works fine on my other devices.

Once I delete a message, T-bird (147.0.4 on W11 Pro) begins compacting, and then I'm stuck until it's done. This is new behavior. Previously the system compacted occasionally, but now it's every single time I delete something from the inbox (which happens frequently during the day, of course, sigh).

Anyway, many thanks in advance for help/guidance and if it matters, I'm one of those who contributes monetarily for use versus freeloading. Also, no, we don't believe updating to the latest version is productive for our situation so I hope this is not the solutuion. -- Regards,

After the last update Cabela's and Bass Pro websites are blocked, won't connect. Teva has been blocked for over a year, and I can't find a page on here where you can instigate a trouble ticket.

Firefox has been a great browser until lately, I'm disappointed guys!

Firefox browser has stopped opening websites on my Dell laptop. Get "secure connection failed" error message. Other browsers work just fine. I have refreshed, uninstalled and reinstalled Firefox from both firefox website (using Brave browser) and from MSN store.

Best Buy Tech support took control of my computer today to get my printer to scan to the computer. After that was done, I went to my FIREFOX hompage only to see it completely changed from the way it was and I am now trying to get it back.

when putting in Yahoo.com in Firefox search window, it will open the link but then the page disappears after 2 seconds. I am on Dell Inspiron 15 laptop with Windows 11.

Je n'arrive plus à me connecter, voici le message d'erreur "Échec de la connexion depuis le serveur imap.sfr.fr avec le nom d’utilisateur beaudonnat.jean-luc@neuf.fr. Pouvez-vous me dire ce qu'il faut faire pour me connecter. A savoir j'ai changé mon mot de passe mais celui-ci ne me permet toujours pas d'accéder à mes mails.

Recently my system updated Firefox to version 149.0.2. It works great! However, it will not display my homepage which is yahoo.com. I can go to any other website and everything is normal. But when I click on the little house for "Homepage" it briefly displays and then goes blank.

This does not happen when I use a different browser.

Please advise.

When trying to search in Yahoo, using Firefox, About:Blank comes up instead in a new tab. I have to hit the X to close the new tab, and then hit enter again and I will then get my search results. I have 2 PCs and a laptop and they ALL are having this problem since the last Firefox update. I have tried ALL of the recommended fixes, I have refreshed firefox, cleared cache and cookies, turned off firewall, antivirus, extensions, etc. I have even tried some of the config recommended changes and NOTHING works. It is definitely a Firefox problem and NOT a yahoo problem because all works fine in Chrome and Edge.

Why cant I set it to always translate spanish to english??? That option is greyed out and every time i encounter a spanish page I have to manually translate it. Im getting tired of that.

I can't find latest Firefox apk for my android. It only shows play store link. I tried signing up for Gmail account but that requires phone number verification these days. Never in my life was creating a Gmail account so much hard. It doesn't even give option to get code on some other number. The only option it shows is to insert a sim and google will verify itself which is kinda annoying. Please share the latest official Firefox apk link. It's impossible for me to create Gmail account as there is no Sim in my phone.

Hello, Firefox has been giving me some troubles lately and I can't figure out how to resolve the problem. Since I haven't found any way to consistently reproduce crashes, it is very hard for me to tell if Troubleshoot Mode also experiences the crashes, and the time I can spend doing that is very limited. As previously stated, it is very inconsistent, but relatively frequent, sometimes it crashes very soon and several times in a day, others it doesn’t at all. Sometimes it crashes with several tabs open, sometimes with only one; sometimes it crashes while using a webapp, others it does so on the newspaper page. It might be more frequent while there are Electron Webapps open, but it's more a hunch than anything, since sometimes it happens without those. I have followed the steps in: https://support.mozilla.org/en-US/kb/troubleshoot-firefox-crashes-closing-or-quitting Been unable to find the cause so far. Here is the crash report ID from the latest crash: bp-60cd6ea9-9bd1-411d-a0ca-2f6fd0260415

The crash report does include information on my system, but please let me know if any other information might be useful.

Thank you very much in advance and I hope you're having a great day.
