Hello, Attached are the messages I have been receiving ever since 6 October 2025. I've tried to read about fixing these myself, to no avail. (I mean, I can Read; I just can't fix this.) I've tried to Compact ALL folders individually. But that seemed to do nothing. (Before 6 October, the Thunderbird window would at least "flicker" a little after compact.) Trash is empty. Tried disabling McAfee AntiVirus & Firewall. And, no, this isn't happening because I'm using McAfee; I've been using McAfee since Windows XP and Thunderbird since before it "broke away" from Mozilla. They have, until 6 October, played nice together. I really like Thunderbird so I do not want to find another email client/program/what-have-you. There are LOTS of saved emails that I cannot move/copy to "save space", so...Help? Please?

Thanking you in advance, tonyg

P.S.-I am not computer illiterate. But, slow, easy to follow, non-BIOS changing, step by step directions would be preferred.

In the past I've been able to print pages generated from websites, such as ... https://www.bridgebum.com/short_suit_game_try.php

I recently used a well know "cleaner" to remove broken links etc ... Since then I've been unable to print these generated pages. I can still print documents that I've created. mail etc so it's not the connection between my PC (Windows 10) and the printer (canon TR7560)

I've tried the troubleshooting ideas in FAQ. I've reinstalled (without uninstalling) Firefox but neither helped.

Cheers from sunny Sydney Australia

Hi All,

I was using the following CSS to hide the navigation images and show only text labels on the context menu for the Back, Forward, Reload and Bookmark Page menu options...

/* Content Area Context Menu - Navigation Vertical Text */
#context-navigation,
#context-navigation > menuitem{
  flex-direction: column !important;
}
/* hide images */
#context-back image, #context-forward image,
#context-reload image, #context-stop image,
#context-bookmarkpage image{
   display: none !important;
}
/* show text labels */
#context-back:after, #context-forward:after,
#context-reload:after, #context-stop:after,
#context-bookmarkpage:after{
   content: attr(aria-label) !important;
   margin-inline-start: -19px !important; /* this pushes navigation text items to left, aligned with other menu items below */
}


It worked up until a couple of versions ago, but something has changed, and my CSS is now broken, and those navigation icons are back.

My context menu now looks like the attached image below.

Any help with showing only text labels on this menu is appreciated.

Thanks.

I am really really distraught right now. It took me two weeks to get the time and focus to write a long reply to a company's nice email to me. Stayed up till 2am to write it. Deliberately wanted to re-read it in the morning before sending. Gone. Nowhere to be found. I pressed "Save to draft" before closing my laptop. But not saved. This account actually has a "draft" folder, unlike most of my other accounts in Thunderbird, which I also cannot figure out and no one has helped me with.

When sending an email using the keyboard shortcut, the settings tell me that I can set TB to give me a confirmation prompt. Why can't I get a confirmation prompt when using the Send button? Is there any way to make TB do that?

I set TB to run a spell check before sending, and that gives me an opportunity to cancel the Send operation. But it only works if the email contains a misspelling.

Thank you.

Hello, I have spent the last couple of hours reading through other questions and posts but nothing seeemd to work. If I try to copy a shared link in OneDrive or SharePoint on my desktop and then paste that link into Outlook Web App, the paste function does not work. The option is there, but the actual pasting does not materialise. CTRL+V also does not work. The only thing that does work is if I paste the link into another window first and then copy again, and the CTRL+V works. Right click and paste never works. I have tried this in a private window and in safe mode. I have also checked the clipboard settings in about:config to make sure they are not working against me. It works fine on Chrome. I made a quick Loom to demo the issue: https://www.loom.com/share/911ae68d614947aa9ea6beaba0d2f5b0?sid=2257b601-939b-4d95-90d8-bb2c95b1ed81 Firefox is up to date, as is Windows. It has been like this since I moved over from Chrome a few weeks ago. Is this a common issue or a 'me' problem? I have seen all the workarounds, but I am trying to understand why right-click, paste just doesnt work. Any suggestions are much appreciated.

Hey folks, I recently installed a new NVME, clean Windows install, clean Firefox install. Recently I've had seemingly random crashes on tabs, happened a lot with YouTube and seems to happen fairly consistently if I go to my watch history. Other sites seem okay, everything else seems to be working fine, checked my drive, my RAM. This Firefox install is using my Mozilla account for passwords and themes. Included a recent crash report if that helps. Thanks if any of y'all can help
