Hello, I am from Ukraine and I use a translator, sorry for that. I have poor physical and mental health. I have Windows XP and there is no possibility to buy a newer computer. Yesterday all my browser extensions were disabled. They are very important to me. I accept and understand all the risks. I beg you, please let me use these extensions. Please help...

Hi,

I put some messages into folders yesterday and then created another folder and dragged the first folder into it to become a subfolder.

When I did this, I saw the new folder but it couldn’t be expanded to show the subfolders.

All other mail clients showed the correct hierarchy except Thunderbird.

Why is this happening?

Secondly, I post comments on the thunderbird blog regularly but they never show up. Where are they disappearing to? Are you receiving them?

There used to be a menu in the message header (lower right of screen) that included viewing the message source. I accidentally deleted it and cannot find how to restore it. I have looked through the Config editor and main menus and cannot find an option.

Hi,

I have a very old version of Firefox (51.0.1 64-bit) on Windows 7 Pro. I know it's well out-of-date. It's not my "main" browser, but there are some things I use it for because there are (were) some handy old extension on it. For example there's an extension that simply copies any text I highlight, without my having to press CTRL-C. I find the "scrapbook" invaluable for saving info offline.

Yesterday everything was fine. Today ALL the extensions have been disable because "[extension] could not be verified for use in firefox and has been disabled". There is no option to enable them again.

I have backups of the extensions (xpi files), but firefox is telling me that they appear to be corrupted.

Is there any way to either enable the disabled extensions, or force firefox to reinstall then from my backups? I have toggled "xpinstall.signatures.required" to "false".

Thanks for any help.

Hello, Thanks in advance for your help. I am having trouble logging into "trusted" web sites with Firefox and every update seems to add to my problem. By "trusted" web sites I mean sites like Charles Schwab, Spectrum and iCloud as well as my city's water department and my local hospital's portal. It doesn't matter whether I use "normal" Firefox or its privacy mode or safe mode-the problem persists. I am running Firefox version 134.0.2 but the problem goes back several months. I have Windows 10 and use Malwarebytes Browser Guard. The only other add on I use is Print Friendly & PDF. It doesn't matter whether these addons are running or not. The problem seems to involve either a loop, blank fields or very odd error messages. Some examples are below:

iCloud allows me to get to the point where it asks me to supply the 6 digit verification code. I enter the code and the site loads. Approximately 2 seconds later, before I can navigate to anything in iCloud, I am taken back to the log in screen to start over. The loops repeat as often as I want to try. Clearing cache and history does nothing. Since there is nothing abnormal (no error message or blank fields) I have not included a screen shot.

Spectrum allows me to enter my credentials waits a while and then gives me an odd error message about Feature Unavailable and suggests that I try logging in from home. I might add that all of these problems occur while I AM at home. Screen shot attached.

Charles Schwab allows me to get to the log in screen but the screen is unusable. There is a message that the session has timed out and I need to log in. The log in sections of the screen are blank which leads me to believe that the page is not loading all the way but that is a guess. Screen shot is attached.

I can log into all these pages with Edge (which I dislike using) with no problems at all.

I have Firefox set to automatically delete cookies and site data when closed. Privacy is set to Standard.

I would really appreciate any help that you can give me. Please note that the screen shots are BMP files that I had to rename to GIF files to get them to upload.

Thanks again,

Charley

very frustrated, and pissed at how programmers always screw things up that are working just fine by upgrading crap. Now, I have suddenly had all of my addons quit working, was forced to update my firefox. Nothing changed, and it still shows that I am using version 105, instead of the all-new, better and fancier, singing and dancing crap that is being forced upon me.

Please put Thunderbird back the way it was. I have several different email accounts in Thunderbird, I'm obviously logged into Google on one of those accounts, but for a while now TB constantly asks me to "Login to Google" - when I already am. i.e. It's asking me again and again, to login to one of the OTHER email/google accounts - and I don't want to, because I bet the moment I do, TB will popup the window again, wanting me to login to previous one. And so round and round we go.

Also the popup is poorly designed, because not all of it fits on the screen. i.e. It's oversized, so you can't see the top or bottom "bar" and there's no way I can see to adjust it. I detest this pointless popup, constantly appearing, having to first click on the white space, and then hit the ESC key to get rid of it (until next time). Why would you do this? We've always been able to have multiple email/gmail accounts, all with different login details, and all the email accounts still seem to be receiving email okay... so why add this annoying popup? Please remove it.

I received a PGP-encrypted e-mail which is just showing the encrypted text in mail preview and also in a separate mail window; it is not getting auto-decrypted, even though the correct key is present in the OpenPGP key management. I have this same behavior on two different setups on Linux Mint 21.1 Vera. Once I reply to the e-mail, the original message gets decrypted in the reply message, but not in the original.

I've got another setup on MacOS, same Thunderbird version, which also does not auto-decrypt the message, but in message preview provides a button "Decrypt" which does the job. But this button is missing in the Linux configs.

All setups have the correct PGP Key configured.

Any hint to resolve the issue is highly appreciated. Thanks for your time.

I am having issues with Thunderbird accessing emails from Comcast.net. This issue started over the past weekend. Nothing has changed with our Comcast setup or our Thunderbird setup. Please advise.

Thanks. Sam Orner

I've just updated Firefox to 136.0 and found the "return closed tab" key became blank and ineffective. I read the update log but didn't find infomation about this change. The function was useful to me and I hope to get it back.

I've tried the troubleshooting steps outlined in the FAQ but have not been able to send any email messages. This just started a few days ago and I've tried these things with no luck:

• Disable firewall
• Disable anti-virus
• Change SMTP settings
• Change email account PW

Windows 11 Norton 360 NordVPN

I don't know if this has any bearing on the issue, but at the same time as I began having trouble sending email, I attempted to install the UPS label printer software. It also looks like there was an update to my AV/Firewall software, but since I have disabled both, as well as disabling the VPN, and there's still no success, I'm ruling those out for now.

NOTE: I have no trouble sending or receiving email with my phone, so I tend to thinnk it's not the account settings. I've tried using the phone as a hotspot to send from my PC but that also was not successful.

Thanks in advance for any assistance!

Hello,

Please apologize my errors, english is not my mothern language. So, my vocabulary may have some lack, and the terms i use to describe some menu's elements are not the one used on the english version.

Last friday, Win 10 update itself. Cause a lot of trouble. I've uninstall this update and all seem to be well again. With Thunderbird, the main problem was i was unable to send a message : smtp problem (which is not due to thunderbird nor from my mail provider, but from W10's update) But there still a problem with my beloved thunderbird : - the templates i use are inactives. When i double-click on them, nothing happen. Even with right-click, "new message from template" : nothing

The only way to use them is to right-clic > open > open in a new [tab/window] > copy and paste in a new message... Even "Modify as a new message" is not working except if i first open it in a new window (and then, when in this new window, CTRL+E).

Before that mess, i was running 128 ESR (up to date).

In desperation, i've done that : - Testing new install of 128 ESR with no uninstall of previous version : same problem - Testing new install of 136, with no uninstall : same problem - Done these both again with uninstall : same problem.

Restarting my computer each time, off course (some much time lost from this morning... ) That's feel me crazy !

I will be grateful to have some help.

PM

PS : W10 because it's my work's computer. No choice for the moment

The other day I discovered all my extensions have been disabled. I have an old Mac and am not able to upgrade to a newer version of Firefox. Is Mozilla going to offer a solution for people like me who find their preferred browser to now be frustrating and inefficient? I would love to restore my add-ons. Thank you.

My automatic address has recently been changed in your system from: [edited private information from public] to: [edited private information from public] Please delete the second and revert to the first. Thank you. Roger

apparently, programmers don't understand how aggravating not having backward compatibility is to the rest of us, so please bear with my extreme aggravation here. IF IT AIN'T BROKE, QUIT FIXING IT.

 firefox disabled my addons, thus forcing me to upgrade, and now I am angry. Tried downloading the new version several times. My os is as updated as it can get. Using the APT link from this site, it just shows garbage. Using the download for linux 64 bit link, it makes me jump through hoops and looks like it is working, but it looks different and none of my bookmarks transferred over. Closing it down and reopening it, I see the old version, thus making it look like I am possibly running both versions separately. Once the *all new singing and dancing special that is supposedly so much better than the old that some ignoramus decided I MUST use it instead of the old and functional one* is closed out, I see no way to reopen it. And neither version will enable or allow me to download singlefile. That is the only program I need from firefox at this time.
 Will somebody please show me, step by step, as if I am 5 years old, a back door that will enable my addons, before I go nuts and start beating programmers to death with reams of algorithms?

I am able to use quick search on all of my folders EXCEPT the Sent folder and it's sub folders.

Example: When in the Inbox, I type part of someone's email and I see all the emails with that as part of the email address. BUT, when I do this for the SENT folder and any of the sub folders and nothing comes up. Even folks that I email several times a day it does not find them

When I put Thunderbird into Troubleshoot mode, the quick search works.

Another issue is when doing a global search for all folders, I will see something in sent, but when I click on it, Thunderbird does not find the email. This happens with the SENT folder only.

I have tried a few solutions, including rebuilding the Global Database and making sure this folder is part of that.

what am I missing?

Thanks for any help Chris

After Update 128.8.1esr installed on 3/19.2025, I cannot receive or send messages. Worked fine in the morning on 3/19 and after update I get nothing. I have an AOL account for my email. I can get my email by going through the AOL internet site, but nothing through Thunderbird. The previous update was 128.8.0esr installed on 3/7/2025, and that worked fine.

This is a strange issue. I've been using Thunderbird for over 15 years, and today, while working with a client, I attempted to click "New Event," but it was greyed out. After ending the call, I started troubleshooting.

Steps I’ve Taken:

• Re-added all existing accounts—no change.
• Tried adding a fresh calendar—received a strange error (which I didn’t copy) about encryption or a "request missing required authentication credential."
• Uninstalled Provider for Google Calendar and removed all accounts.
• Same authentication error—Google sign-in system wouldn't appear.
• Searched Google for recent similar issues—nothing in the past 30 days, nothing within the past year.
• Restarted my computer.
• Was able to re-add all accounts, but nothing is syncing.
• At this point, I’m completely baffled. No system changes have been made. I'm running Windows 10 with the latest version of Thunderbird and its extensions. My system clock and timezone are correct.

Any help would be greatly appreciated!
