When I select emails to move to another folder, Thunderbird 143.0.1 (64-bit) will not show me the number of emails I have selected.

I have tried every 'online' fix out there, and none of them seem to work.

Can someone please help me?

sincerely, Ken Wagoner Harrisonville, Missouri

I get messages in my spam/junk folders that are not spam. I have tried marking the as "Not Junk" many times but they still wind up in the junk folder. The recommendation I read in your Forum is to "white list" (or is it "whitelist" ?) them but I can't figure out how to do that. Please help.

Hi everyone,

After enabling `privacy.resistFingerprinting = true` in `about:config`, I noticed that Firefox’s built-in PDF viewer (`pdf.js`) is always displayed in **light mode**, even though my system and browser themes are both dark.

I understand that RFP forces `prefers-color-scheme: light` to prevent fingerprinting, but this also affects internal components like the PDF reader. Unfortunately, the PDF viewer doesn’t provide a manual dark mode toggle.

Is there any **official or safe workaround** that allows keeping RFP enabled while still having the PDF viewer use dark colors?

Thanks!

Hi. I am trying to migrate Firefox from my wife's laptop to her new one, using sync. I've followed the instructions, set up sync on the old one, then set up sync on the new one with the same account. Nothing changes! Where am I going wrong? Or will I have to do a manual transfer instead?

Thunderbird is deleting mail from my inbox every time I download new messages. I double checked my settings and they are correct, so this should not be happening. How do I prevent it?

A website has moved a while ago, but when I type in the first few letters, I still get the URL to the now defunct site suggested. I tried long-pressing the entry under "Firefox Suggest", but do not get any options to remove it.

Since the defunct URL starts with the same 10 or so characters as the new one, I always have to type a lot to get to the correct page. On the other hand, I use it to rarely to warrant a bookmark.

У меня Windows 11 Pro, скачивал firefox с прав администратора, но обычно после установки в правом верхнем углу появляется значок входа в аккаунт фаерфокс, которого сейчас у меня нету. Прошу если кто-то знает ответ или сталкивался с проблемой - помогите, мне срочно нужны пароли, которые остались на аккаунте

On all our computers it seems impossible to sign into Outlook...several laptops and 3 desktop...even a new Apple device. Enter your email address and then taken to the next page (see attachment). sign in works with Edge! This has been happening for maybe a month. Very frustrating! NEVER opens the next security window, the 'spots' just keep moving forever...selecting "Back" just repeats the cycle.

My problem is the following. The website of my favorite football club regularly embeds videos within their pages. Clicking of the video within the club webpage shows the video without leaving the webpage. Recently opening the club site with mozilla stopped enabling me to see the embedded videos. An example of what I see on my screen now when using mozilla is in the first image uploaded below - instead of showing the embedded video, all I see is a small red rectangle with a "play" button in it. If I press the play button, the video starts, but shows within the extremely small rectangle and I cannot watch it.

This is not so when I use Edge or Chrome, as shown on the second image uploaded below, showing the exact same webpage (the address is https://levski.bg/video/%f0%9f%94%b5-%d0%bb%d0%b5%d0%b2%d1%81%d0%ba%d0%b8-31-%d0%b1%d0%b5%d1%80%d0%be%d0%b5-%d0%b3%d0%be%d0%bb%d0%be%d0%b2%d0%b5-%d0%b5%d0%bc%d0%be%d1%86%d0%b8%d0%b8-%d1%80%d0%b5%d0%bf%d0%be/ ). The embedded video is clearly seen in its full size within the page, and when I click the play button it starts showing the video normally within the webpage without leaving the site and sending me to youtube, for example.

My question is, what is wrong and what can I do to start seeing the embedded videos normally again?

Thank you, Georgy Ganev

I joined a Microsoft Teams meeting through Firefox on the web on a Linux machine. When I tried to share my entire screen, I was asked if I wanted to share the entire screen in a Firefox pop up which I said yes. Then the "you are sharing your entire screen" came up, the sharing icon was red and the "stop sharing" button was red. See attached image. This all disappeared and reverted to the default state almost instantly.

Teams has a feature to "manage what attendees see manage what attendees see" where the meeting host can preview shared content before making it live.

I am concerned that the meeting owner was able to see my entire shared screen without me even knowing it through this preview.

Can someone help? Microsoft just sends you around in circles and I can't contact Mozilla.
