When I try to go to my webmail I sometimes am presented with a Deceptive Site Ahead warning.

I am quite happy that although the SSL might not be current that the website is safe for me to go there. How do I stop this annoying feature from activating?

when clicking an email link this is shown

"Thunderbird is already running, but is not responding. To use Thunderbird, you must first close the existing Thunderbird process, restart your device, or use a different profile."

How do I make Thunderbird instead open a new email?

This is on Fedora

Hi, Firefox Mobile doesn't launch Teams app when I press 'Join meeting', nothing happens. 'Get Teams' works. 'Open links in apps' are enabled in Settings. If I share the link to Chrome it works fine.

The layout on the Roblox website, https://www.roblox.com Has appeared to break, I've seen the website on Google chrome and Microsoft Edge and it's good to go. I am not aware as to how this has happened. I have disabled every Addon I have, This issue is not caused by the Addons I have installed.

CTRL + F5 has Fixed My Issue! Thank You cor-el!

I wish to try K-9 Mail on my Android - eventually I want Thunderbird. When I start K-9 it offers me "IMPORT SETTINGS" and then says CHOOSE FILE. What file(s) do I need to bring over from my Thunderbird profile to get 1. the address book(s) and 2. the email account data?

Since Thunderbird updated to 115.7.0 yesterday, I can see message headers for new emails, but not the message content. Messages received before the update appear normally. When I click on a new message in the inbox, it will say "loading message . . . " , but then it does not actually load the message, and the message pane is entirely blank. Not getting any error messages. What do I need to do to get it to actually load the message?

Some hours ago my iCloud account stopped working on Thunderbird; I already tried re-entering the password, deleting and trying to add the account again, but it isn't letting me add it again, my account is working fine on all Apple devices and I have access to the mail on browser.

I've tried using the main iCloud address, the "alias" address, and using the real password as well as the unique "App Password".

Thunderbird version is: 115.7.0 (64-bit)

As I said in the Subject I just bought Total AV this month, now its disabled on Firefox. Is this a permanent action? or is this a temporary action? How can/will I get my Antivirus back in action on Firefox?

I frequently open new tabs by right-clicking the current tab and choosing "New Tab" from the context menu. Naturally, I want to start typing a URL or search term.

But the focus/cursor/caret is nowhere and typing does nothing. I have to click on the address bar, and then I can type.

I'm not using New Tab Override and I have Firefox's new tab set to a blank page.

I tried disabling all my add-ons, but I still had the problem.

I tried setting new tab to the Firefox home page and for a short while I got a cursor in the address bar. But the problem returned after a few hours

Any clues on what might be wrong? Firefox version 120.0.1 (64-bit) on MacOS Ventura 13.5.1. Thanks!

(A similar problem is described here: https://support.mozilla.org/en-US/questions/1420220 -- but in my case this is not a container tab.)

Firefox periodically says I am "forbidden" to enter my Kaiser website (KP.org). I know what Mozilla recommends as a fix, which is to clear data and cookies. But this creates more problems because I have to re-enter passwords and other settings. This is a problem Mozilla's website reports has been occurring for YEARS! Why can't Mozilla/Firefox fix this? Please tell me there is a better way to fix this problem.

Hello, I have a problem with setting up HTTPs only Mode in my Organization, I read a lot about that, but I dont see the "dom.security.https_only_mode" switch in GPO, we have the newest admx for Firefox. We need that to specific container, but still I dont know how to set it up, even via regedit, or preferences. Can someone describe me when can I set it up ? It could be using json file (which exactly file and how?), registry or just gpo. Regards, M.

I have Thunderbird set up with two email accounts. Until today I han problems with outgoing or incoming email and had saved passwords. All worked fine. Then I had to change my internet modem and somewhere along the line my incoming password for one of the two email accounts got deleted. No idea how. So I went into Settings and deleted all saved passwords. After that I sent a test email for both accounts and was able to re-save my passwords. But when I "Get Email" for either account, nothing happens. No email arrives (there are new emails on both accounts if I check via webmail). But I also am never prompted to save a password for incoming email (mail.comcast.net) for either account.

Why isn't Thunderbird prompting me to save the incoming password, and how can I manually enter a password? I'm baffled and at wit's end.

Thank you!

I accidentally deleted a fairly large email, namely 3GB in the Thunderbird application, but when I checked in junk/trash the deleted email didn't appear. When I checked locally there was a file called Trash (no file format) with a size of around 3GB and in it there was an email which I deleted previously. How do I return the email back to the inbox?

I loaded the postcode lottery website but it's completely blurred. I last checked the same website last month, and it worked fine. I have cleared the cookies from Firefox, but the result is the same. It appears clear for a moment, then blurs. No pop-ups asking to accept cookies. It works fine using Chrome. Any idea why Firefox won't display it properly? It loads the National Lottery website, so it's not about gambling sites I guess.

Hey,

I've been having an odd issue with Firefox where tabs where I attempt to access youtube.com will immediately crash. This issue first arose when I attempted to log in to Youtube, and had never occurred before. When I did that login, the tab crashed, and I have been unable to access the website since (100% crash rate).

Basic details: The website does not visually load at all. However, the URL bar icons for the website do briefly appear prior to tab crash. (Autoplay button, etc). The crash is never reported in about:crashes.

I've tried the following tests, unsuccessfully: - Logging out of all Google accounts separately - Disabling all extensions - Transferring all of my data to a new computer - Reinstalling Firefox - Rebooting Firefox in troubleshooting mode

This problem does not occur on my Windows machine but occurred on my previous intel-based Mac and now on my current Apple Silicon Mac.

The only success I have had is in creating an entirely new Firefox profile. However, I would prefer to fix the issue, as I assume that porting all my settings to the new profile would... also probably bring the bug along.

Thanks for reading & any advice is appreciated.

i have just downloaded Firefox and i go to open in and it flashes open an close immediately. the occurs every time that i open the program. i have reinstalled it multiple times to see if that's the issue, used the Microsoft store to download it, the website, i tried to get the beta that didn't help and i was just wondering what the issues was and wondering if you could. i looked in the error message folder as well and its empty.

Somehow my Thunderbird email password was changed and I didn't do it. How do I reset my password? Email [edited] @sbcglobal.net when or if you have an answer. Thanks.
