For the last week or so, Firefox on my desktop has opened to a blank new tab screen, and won't load any other pages. It won't even load support.mozilla.org, I'm asking this on my phone! I've had to use Edge on the occasions that I CAN'T use my mobile for the task; printing shipping labels, downloading a better art program, that sort of thing. I'd really rather NOT use Edge at all, thanks.

I just added 2 gmail accounts yesterday to Mozilla Thunderbird. I'm fairly new to Thunderbird, but I was pleasantly surprised that all went well, and I received/sent mail from/to those accounts.

Today I sign into Thunderbird, and it retrieved the emails fine. However, it would not send emails. It kept popping up a box to enter credentials for that gmail account. I entered the email address, but it will not move past that screen. It just keeps reloading the "Enter Email or Phone Number" screen for gmail.

What I have already done (after researching):

 -Access to less secure apps is already turned on for both accounts.
 -I changed authentication method to OAuth2 for both accounts.
 -I have updated to the most recent Thunderbird version: 78.8.0

I have restarted Thunderbird after doing all of this, and each time I try to send the draft, the screen to enter credentials pops up again, and the loop continues, never letting me enter the password. Now it will not even check my gmail email account for new mail without that screen popping up. Please help! I don't know what changed.

TB has worked well for the last 10 years, but sometime in Nov or Dec we can't send emails through Comcast. They say it is a Thunderbird problem because the ports and security are configured right according to them. Lately it will work okay in the morning but not in the afternoon or evening. Today it won't send at all. I get a message as follows:

"An error occurred while sending mail: The mail server sent an incorrect greeting:  resomta-ch2-13v.sys.comcast.net resomta-ch2-13v.sys.comcast.net Excessive failed authentication, ESMTP server temporarily not available."

Why does it work sometimes and then not at all? I have had to revert to a gmail address or send comcast emails using the web. Wading through the mechanical twit that answers the phone at Comcast and then explaining repeatedly on every call to the agent is getting old, and I don't have the 2 to 3 hours it takes to converse with them. If the call gets escalated, it results in a determination that they will have to call me back, and they never do. Then, when I call again they say the case has been closed. Anybody experience this nonsense? What can be done to get the outgoing mail to work again?

I am currently running thunderbird v68 on 4 linux (Xubuntu AMD64) machines using the same profile which is synchronised from machine to machine. However this profile is getting to be unwieldy and contains a number of inconsistencies and anomalies. For example it still thinks it's got emails from 2013 although these were offlined and deleted 7 years ago. History, cache and deleted items are cleared out and folders compacted daily yet the profile (excluding 1.9GB in the mail folders themselves) is still about 1GB a large chunk of which is in global-messages-db.sqlite. I could create a fresh profile but with 6 POP3 inboxes and an IMAP account plus a dozen or so addressbooks accumulated over the last 20+ years it's a bit of a daunting task. Is there any neat way of refreshing the Thunderbird bit while leaving the user data intact or at any rate restoring it automatically? Tks in anticipation of your help jg

When I try to add an existing email account It gives me the message configuration not found! I have checked and double checked all settings, username. password and they are correct. But it denies me and gives an ERROR. See screenshot. Help solving this problem, please. I have tried avery setting and combination ( I mean the choice for protocol, SSL, authtentication methode) Nothing is working. Why?

So the deal is I reinstall my parents windows 10 . The sync on Firefox was on , but they forgot the password after resting the password i lost all my data. The Question is i got access to old Firefox folder and i can see there folder Bookmarksbackup can i restore my bookmarks somehow with this file ?

Hello,

I successfully installed TB over a year ago and yesterday started the process to update the program to the current version. I get a message "Setup - Your computer must be restarted to complete a previous upgrade of TB. Reboot or restart the PC."

I've tried several times...either restarting or rebooting...and keep getting the same message over and over. I went to the Windows 10 app area and tried to remove TB to start over but get the same message when I try to remove TB. No joy.

What next?

Regards,

Monty

How can I get a response to my questions when the replies are no-reply e-mails? I have lost my local folders when I migrated to version 68.11.0 (32 bit). There is no view folder so I cannot use your instructions. Morley Verdier

I selected the new HTTPS-Only mode in Firefox 83.0, and some URLs are being blocked, followed by the "Secure Connection Not Available" message. Yet, when I click "Continue to the HTTP site," the site URL is HTTPS, and the grey lock in the URL bar is in the fully secure position. Please let me know what this means, or whether this is a bug to be worked out. Thanks in advance.

The Mint20 software updater just pushed a TB update from 68.1.0 to 78.7.1 and now, I too have a folder pane full of useless whitespace between folders.

I've read what I believe to be every one of the threads on this problem in 78.3.x, but even after setting toolkit.legacyUserProfileCustomizations.stylesheets true, locating the current profile folder, and creating the /Chrome/userChrome.css file, *none* of the various .css hacks suggested for reversing this change or regression work in 78.7.1. All such changes are ignored.

If anyone has a way of reversing this bug or regression in 78.7.1, I'd surely appreciate it.

When I activate the QR scanner on the Firefox UI on my iPhone to read the code on my laptop, iPhone Firefox says I used the iPhone camera and should use the reader from within the app. I did that as far as I can tell, so what went wrong? Can anyone please help me with this. Thank you

How do I disable the ANNOYING message box I get every time I want to send a message to the trash folder. Thunderbird keeps asking me if I want the message deleted to save disk space. This just started in the past week. I want my deleted messages to go to the trash folder and I will manage that folder. I can't seem to find anything in settings that lets me disable this option.

On certain websites I can't login, firefox keeps opening new tabs with the same login page. For instance, I try to login on Zulily, I click the 'sign in ' link in the top right corner of the box (image 1),I enter my email address and password (image 2) and click the 'shop now' button. I'm redirected to the first screen (screen 3), I did not just rename image 1 as image 3 and re-upload it. Image 3 is the actual 3rd window I'm redirected to. I have cleared cookies and caches and histories and deleted possibly corrupt cookies.sqlite files. I have cleared the startup cache and disabled add-ons and logged in in safe mode. I have uninstalled and reinstalled firefox. It's not all sites with logins, either. just certain sites, and it remains consistent which sites I can or can't log into. I have googled this problem with as many different re-wordings as I can come up with and no one else seems to quite have this exact problem. I'm running Firefox 86.0 64 bit for linux mint on Mint 20.

I got a bug, or a hack, or a virus that corrupted my FIREFOX so had to uninstall and re-install.

Have got most of it fixed except I can't get the BOOKMARK "BAR" to display [see pic attached].

If I select "Bookmark" on the top bar, it opens the bookmark window but I want it where it has been for over a decade, between HISTORY AND TOOLS.

I downloaded the current rel 86. My first FIREFOX copy was ~2004/2005 ver 1.0.

Hello. In any firefox windows, the glitch (see attached images) is present, Any time i mouse over an interactive elelment, all of the speckles change position, and sometimes color. they look to be very random, sometimes being absent from a large part of the page, and other times being very thick throughout it's entirety. the only way i have found fix it is by downgrading version, however i still would like to know if there is a solution for fixing this version. in chromium browser, this glitch isn't present, it also only, in the past, displayed on pdfs, and some iframes (HTML term for embedded websites in windows), but now it covers the whole page, it isn't unusable but sometimes is hard to look at. This glitch has been present for at least a week (current date is march 1st) but definitely longer. Thanks.
