Hello, I've been happily using Thunderbird for a few years now. Since yesterday, I have been unable to send emails in Thunderbird, but I can receive them. I can send emails directly through my Skymesh Webmail, but in Thunderbird when I try to send an email, I get the following notification, even if I am sending it to only one recipient. Sending of the message failed. The message was not sent due to exceeding the allowed number of recipients. The server responded: Insufficient system storage. Please help.

My friend recommended this browser to me. When I tried to customize it, I couldn't find an option to change the hotkeys to my preference. I consider this feature important since I use it for work. Can I do this somehow, and is there any plan to add such a feature to the settings?

I'm afraid I picked up malware despite Sophos due to this message upon routine searches, e.g. "Where's the nearest pet store". About this page Our systems have detected unusual traffic from your computer network. This page checks to see if it's really you sending the requests, and not a robot. Why did this happen?

It's preceded by the reCaptcha request to check the box stating I'm not a robot.

Thunderbird message header pane is so large that I can't read messages. The top 2/3rd of my screen has the list of messages, header bar, files, etc. The bottom 1/3 is for the actual email message, but the header takes up nearly half of that with just the "From", "To", and "Subject lines taking up more than half of that space. Depending on the text of the html message, sometimes I can only read one line at a time, which makes it difficult to actually comprehend a message while scrolling, particularly if it's a long message. I can't resize it to make it larger, though I can make it smaller. My eyesight isn't quite as good as it used to be so I use a larger font than I used to, ie: 12pt rather than 10pt, and that makes it worse. Any suggestions?

I get a notification that includes this message when I try setting up my outlook account and this prevents me from getting mail to my email in Thunderbird, not past or new emails show up and I can only view an empty inbox, contrasting my other emails which work perfectly fine.

When I try setting up my email It says my username or password is wrong when it isn't and when it input, and that I have to put in my login. I put my login in and it says my username and password are incorrect even though my login info is correct I don't know what's going on, the error info isn't very helpful.

I cannot sign in. I see a box showing Mozilla Thunderbird below above it says Micros I see my Micros account. I have 10 password I haven't used any them that I remember. If I try too many times I am blocked. I was able to see what I would have to to get a QR code but not anymore. When I tried to get code last a few days ago There were black vertical lines moving from left to right so I could not take picture using my S23. I did some search and it I have to change some setting on my S23. I have new version of Thunderbird on my S23. No password since I have not been able to take QR image. This is not working for a week now. No emails to my S23 account. Please help me.

I'm experiencing problems across numerous sites using the above version of Firefox, detailed below. Other browsers are OK, as are other versions of Firefox on different devices.

Outlook365 email - "Your message can't be displayed right now" Fantasy Premier League - unable to log in, hitting 'Log in' doesn't respond Faceboook - content does not load Ebay - html on formatting in listings is screwed up Duckduckgo non-functional - returns the message "Ugh, it happened again! The server encountered an error and could not complete your request." The Guardian - images do not load Nextdoor - messages do not load

I used to get my emails from IMDp on my email account. I am not sure what I did to change something but I can no longer get emails.

What did I do to screw this up? Where do I go in the help list to get my emails back?

Thank you

Firefox update today 1-14-26 says Restore FF with a backup file" Instructions say go to Settings/Sync/Backup/Manage Backup. My Sync has no Backup option, only shows: Sync Manage account Device Name Syncing: ON You are syncing these items across all your connected devices: Bookmarks Open tabs Add-ons Settings Connect another device . How to proceed?

(I don't recall setting Syncing to "On" before; it also showed me as automatically logged in to my account.) Assistance appreciated! Thanks!

Since awhile while, the items I send, don';t show up in the sent folder of that account. The complete folder is empty, which means that I also lost messages. I didn't make any changes to the settings, it might have happened due to an update maybe?

My other accounts work still fine. I checked all settings I could think of that might affect it, but haven't found a solution. I'm getting pretty desperate and hope someone can help me out.

It's an IMAP account. I've selected the 'sent folder' in subscribed. 'When sending messages, automatically' the 'place a copy in' is checked and directed to the email address. Also tried it with checking 'other' and select email address. I also just tried to 'local folder', but nothing happens.

I hope my description is fine. If more info is needed to tackle this problem, I like to hear!

I upgraded from windows 10 to 11 My son was able to recover my e-mail folders, but some large folders are missing and the remainder only have e-mails from 2019 or earlier. How do I recover those e-mails? I am no longer conversant with the current technology or terminology. I need simplistic instructions.

When accessing important accounts on websites, like financial websites, I've always heard you should close your browser when you're done with the secure website. If you log on in a PRIVATE window and close the private window afterword but leave the main FireFox window open, is that the same thing? I think it is and the private window will delete any login or activity info as if you closed the browser, I just want to confirm with someone more knowledgeable before I make a bad assumption. It also seems to have the added benefit of deleting anything you might download and save elsewhere from the download folder so you don't have to delete it from the DL folder and then the recycle bin. Seems like it's good practice to use the private window this way. Again, just looking for a 2nd opinion.

Thanks,

I am using version 146.0.1. When I try to change accounts order from "Account Settings" by dragging and dropping the account and restart TB then it is returning to previous order. So I am not able to change the accounts order. Thank you. Ulvi
