I have been using Thunderbird for a few months and changed my Google Password(even though Im not quite sure if the error wasnt already occuring before that), but now when I go on Thunderbird it gives me a popup window that says "Enter credentials for name@gmail.com on imap.gmail.com". Theres a field for the email-adress, but when I click "Next" theres the following error: "400. That’s an error. The server cannot process the request because it is malformed. It should not be retried. That’s all we know."

These are the things I tried: Entering the old or new Password. Checked if the config is set to OAuth2 in both incoming and outgoing servers and enabled on Gmail-Account. Deleted and tried to (unsuccessfully) reregister my Thunderbird-Account. The same error pops up when it checks my password after the configuration.

I dont know if the password change is actually the cause, since I think I remember the error message appearing earlier today, before I changed the password, but Im not sure. Also, I have another account linked to my Thunderbird, with no changed credentials, and while there is no similar error message, thunderbird suddenly also has problems connecting to it and asks to retry a few times (3-4) before actually connecting everytime I open it.

I am using 140.6.0esr (64-bit) and Windows 10. My Inbox disappeared. I was in it with no problems. Then I noticed two problems. I couldn't open new emails. It said connecting to server or loading content but email was blank. Also when I sent an email it could not copy to my sent folder due to network or file access errors. I could open and read all the other emails in my Inbox, just not three new ones. So I selected Inbox properties and repair. After the repair, my inbox is completely empty. It had thousands of messages. When I do a search for common emails I know were in my inbox, it only shows emails from subfolders. When I go to Inbox properties, it says number of messages: 0

Is there any chance I could talk with someone? Or that someone would call me? I'm not experienced in Thunderbird or email settings. And I don't like having to do it online. Richard Higgins Concord Mass

Hi, i synced everything, in your browser, checked it few times, i had all my bookmarks from chrome to firefox few months ago, reinstalled windows, downloaded firefox and connected to account its clean, no of my information is there, wtf? i forgot the password, so recovered it. Give back my data for fuck sake, or it was mistake comming from chrome to firefox?

When I click on an email, instead of just showing the email, it sets up a Reply screen showing From me and To Me. At the bottom there is an alert: "A unique identity matching the From address was not found. The message will be sent using the current From field and settings from identity......" (lists my email user name and address). Im not clicking Reply, I'm just double clicking the message to Read it.

Running Sequoia 15.7.2 on MacBook Air. It just started today. I have turned it off and on, no change.

I keep getting this message from google: "400. That’s an error. The server cannot process the request because it is malformed. It should not be retried. That’s all we know.” (see screen grab attached)

Get this error message I think since the update on September 2nd. See below

Unable to write the email to the mailbox. Make sure the file system allows you write privileges, and you have enough disk space to copy the mailbox. Also, I downloads a few old emails from September 2. If I delete them, they re-download when I click on get mail. I do get mail on my phone and on the Xfinity web site. I really would like to get this fixed as soon as I can. Thanks, William Dudzinski - <redacted>@comcast.net - <redacted>

How do I disable the cruft which appears in the URLbar? Specifically, the trackers detected symbol, the certificate verified symbol, the bookmark this page symbol, and the question mark symbols which appear on both the URLbar and the searchbar.

I installed firefox on ubuntu 24.04 following the guidelines from https://support.mozilla.org/en-US/kb/install-firefox-linux

I followed the direction from the section "Install Firefox .deb package for Debian-based distributions", adding the https://packages.mozilla.org/apt repository, prioritizing that over firefox snap from ubunto repors and finally installing firefox.

All good, now I have the latest firefox.

Question: what entry should I add to the "Unattended-Upgrade::Allowed-Origins" section of "/etc/apt/apt.conf.d/50unattended-upgrades" in order to enable unattended upgrades for the mozilla repo?

Googling this got me different contradictory recommendations that did not get my system to firefox 146 until I manually run the apt update/upgrade.

Thanks!

I am getting frustrated that I keep getting multiple folders with the same name. When I save my emails to a local drive I use ALL MAIL to save and retrieve. Now I don't even have the ALL MAIL folder! Vern

I accidentally clicked remember on my credit card when checking out from a cite. I do not understand how to delete it. Every guide online says there is a tab under "Privacy & Security", but when I look for it it does not exist. I have tried searching, cross-referencing its placement in the menu from the videos, but I cant find it. I've cleared my data from the last 2 hours, but still no difference. From the videos it should be between Password and History, but the setting is not there.

I'd appreciate all help that I can get :) Thanks

Over the past 2 or 3 weeks, I've noticed that firefox tabs are crashing more often out of nowhere.

https://crash-stats.mozilla.org/report/index/4a42f4cd-2203-40ba-a40c-616590251210#tab-details

Here's one of the links for the most recent tab crash. Other crashes pretty much were all the same. I can't read or understand this, so I was hoping someone who can is able to tell me what is wrong.

I fear that it might be hardware related, as I've had tabs also crash on Edge and on a new install of Firefox Developer Edition (which I downloaded simply to test if things crashed there as well.) I've also noticed programs like Discord & Elgato Wave Link sometimes randomly crashing as well - but I'm unsure how to pull logs for those, Firefox was the easiest.

My laptop's hardware specs are as follows:

Lenovo Legion Pro 5 - 16IRX9 Processor: Intel Core i9-14900HX (2.2GHz) Installed RAM: 32 GB GPU: GeForce RTX 4070 Laptop GPU Windows 11

If you need more information, please let me know.

Here are some previous crashes that I've reported as well:

An elderly friend uses Thunderbird on her laptop, and up until recently it has been fine. Then it just sits there and doesn’t show any new emails, just kind of frozen. She can send emails but not receive them.. Previously another friend had downloaded BT software to act as an alternate to access her @btinternet.com emails…. Strangely she hadn’t received any emails for a few days…. I found that her emails were being auto forwarded to an unknown email. I disabled that and her emails arrived and were visible on the BT site. I downloaded the thunderbird app to her mobile and attempted to set her account up , with no luck.

Any suggestions. Should I delete the thunderbird stuff on both laptop and phone and re-install?

Thanks

I have the latest version of Firefox on my Mac with macOS Tahoe latest version.

I open a new Firefox web page, all is OK BUT suddenly without my interaction it “zooms” to an unusable size.

I tried to reload but, this makes no difference. The only solution is to open a new Firefox web page.

I went to the community support page and typed in the problem.

I then tried “Share Data” > this opened a new page.

I then discovered that my input on… https://support.mozilla.org/en-US/questions/new/firefox/form ...had been erased. I had to start again.

Firefox is generally my favourite secure browser, but this issue needs to be fixed.

Thanks AJ

Maybe a red herring: I was in the middle of doing a Documents folder backup when I decided to open Thunderbird for some reason. Got an Unable to Load Profile type of message. And my attempts at a fix seem to just send me further down a rabbit hole. I started out by renaming my profile.ini file, but I really didn't know what the heck I was doing and possibly caused more harm than good. Then I tried to find my profile file/folder itself, using the Thunderbird > Troubleshooting > Profile Folder path and doing an import from inside TBird but that ended up with various problems such as drilling down to the profile folder from within TBird but then when I clicked Select Folder in Thunderbird, that didn't trigger any sort of import.

I also spent a good deal of time trying to find my AppData folder, finally being able to view it (a hidden folder, apparently), and saw several recently-dated profile types of folders, but again, I couldn't manage to "hook up" any of those folder/files from starting inside TBird and selecting Import... I ended up just stuck inside a folder, not triggering any Importing activity.

Finally I found a profile folder (5yed...) at a higher level on my PC than inside that long AppData Roaming Thunderbird path. THIS profile was inside: D:\DOCS\Thunderbird\Profiles

Now THAT folder I managed to get an Import to trigger. But the result was an Error Message telling me to go find my Error Console. Can you please see the attached Error Code display screengrab and tell me there's hope that this was at least the right file but just poor results that I can fix somehow???

The following is my copy/paste of the text I see in the Error Console display that's in my screengrab after trying to import the above 5yed... profile, in case it helps you see it better:

Also attached below are also:

• a screengrab of a set of profiles I found, but when I drilled down to them from within TBird's Import selections and clicked Select Folder, as far as I got was an open folder, or something like that.
• Thunderbird's Troubleshooting Info "Profile Folder" path.
• Message telling me to see the Error Console. The message appeared right after I tried importing the profile that's stated in TBird's Troubleshooting Info "Profile Folder" path.

Here's the copy/paste of the Error Console message display after my try at importing the profile that is in the path that TBird's Troubleshooting Info page "Profile Folder" states (maybe it's the same as my 5yed...profile import try's Error Console display, dunno:

Thanks for any help in getting through this.
