I am getting notifications with the Mozilla logo or sometimes with McAfee logo saying "5 Viruses found, your computer is unstable" and various other warnings. They all also say "via qltuh.titanicooler.top" I have attached a picture.

I have closed the browser, I tried clearing my cache, I have scanned using both AVG, AVAST, F-Secure Online Scanner, and Microsoft Safet Scanner. I am not quite sure what else I should do.

Thank You

I am facing issue while downloading files in Firefox Private Browsing. Whenever I download my PDF files, as soon as I close the browser window, the files also get deleted automatically. What should I do to rectify this issue.

Hi, Before Firefox's Version 125.0.1 (64-bit) latest update I could download any file from my safe office environment, behind firewalls, VPN, ... Now despite of unchecking the "Block dangerous downloads" I'm still unable to download files. I have Windows 10 on my laptop.

Here are the steps: Click on a file, Save "File not downloaded. Potential security risk." Click on the message - Allow download The result is a file with content "HTTP Status 405 – Method Not Allowed".

Please help me to work the downloading again. I am aware of the safety but I want to switch off this feature.

Thanks in advance for help, Tibor

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.

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.

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?

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!

Hello, I received a Yubikey 5 and all is working fine using GPG with it, except integration with Thunderbird on Windows.

I followed this guide: https://wiki.mozilla.org/Thunderbird:OpenPGP:Smartcards including 64 windows section

I was able to successfully send mail to myself, but then thunderbird failed at decrypting this message: Thunderbird is indicating that key is not available and I see no prompt from gpg-agent. Key is correctly declared as GPG external.

If I try to decrypt tis email by storing it on file and using gpg in command line, it works fine: agent is asking for Yubikey PIN and gpg is decrypting the message. But this is an awful workaround, not user friendly at all.

I also did sanity check by sending to myself a message encrypted with a key generated by Thunderbird: all is working fine, the message is decrypted within Thunderbird.

=> How do you make Thunderbird decrypt message encrypted with key stored in Yubikey? How do you make the gpg-agent called by thunderbird?

There are multiple screenshots attached below, 2 of them showing setting marked in red. Those settings are pre-configured with the firefox.cfg file. I would like to also pre-configure a list of other settings. You can also find those other settings below.

Anyways, i remember someone from this forum told me there is no "official documentation" for the firefox settings which are listed in about:config. Is there an "inofficial documentation"? If you could reply with the exact setting that i have to change according to the screenshot attached below that would be awesome, otherwise an URL for some sort of documentation would be welcome..

Basically all the setting i want to change exists and can be manually edited using the firefox settings, but theoretically could be easily pre-configured with the firefox.cfg.

All i need are setting-names/ids.

A website MultiSafepay.com has saved my CVV number in Firefox.

How do I edit the autofill data?

I can't get to the same payment page, to be in a position to delete it.

Most links on this matter refer to:

 Options => Privacy & Security => Forms and Autofill

However in my Version: Firefox 98.0.1 (64 bit) running on an up to date Windows 10 this feature is missing or deprecated.

Can anyone say how I could edit/delete this specific entry, or point me in the direction of where this data is stored?

In the mean time I can't recommend using Firefox for entering critical security data, where websites can allow the storage of CVV numbers.

Firefox no longer supports Norton Identity Safe Mobile Unlock and Auto Fill UN/PW, anyone have a solution? I have Windows 10 with Norton Extensions enabled and Norton Vault is displayed but does nothing. Firefox is up to date also (that could be the problem; everything worked a week ago.)

I don't know why, it is NOT Ancestry, as I can sign in to it on other browsers. I get this error message below.

Access Denied Error 21 What happened? This request was blocked by security rules. Your IP: 73.94.12.65 Incident ID: 6eae587fcef92d46

I have no idea what security rules, but I am working on a genealogy project and have never had a problem signing into Ancestry in multiple tabs before today. How do I fix this? Besides getting rid of Firefox, I mean. I have the same security extensions on this browser as I use on Vivaldi, Brave and Chrome - I avoid Chrome, but use Vivaldi and Brave regularly, along with Firefox.

I have been using Thunderbird for several years for my GMail accounts, and have always preferred to download my messages using the POP and SMTP protocols, rather than use the IMAP protocol which leaves them all on the web. Google now inform me that "To help keep your account secure, Google will no longer support the use of third-party apps or devices which ask you to sign in to your Google Account using only your username and password. Instead, you’ll need to sign in using Sign in with Google or other more secure technologies, like OAuth 2.0. What do you need to do? Email software, like Outlook 2016 or earlier, has less secure access to your Gmail. Switch to Office 365, Outlook 2019 or newer, or any other email software where you can sign in using Sign in with Google." These changes are due to take effect from May 30th. How can I prepare for them and still use the POP and SMTP protocols after that date? Is OAuth 2.0 appropriate?

Hi Firefox is not showing Accept the risk and continue-button when advance button is clicked. Due to this i am not able to access server. Image is attached for reference.

I tried most of the things i know (reinstalled, clear cookies and data, cleared history) but it's not showing this option.

Using 96.0.2 (64-bit) on Window 10.

Pls support

Hello I'm referencing the topic where TLS 1.0 and 1.1 support was removed but rolled back to accommodate some government agencies / sites and support for COVID-19 data

https://support.mozilla.org/en-US/questions/1290040#:~:text=Mozilla%20and%20other%20browser%20makers,and%20performance%20of%20Internet%20connections.

Quoted answer "Right, support for TLS 1.0 and TLS 1.1 has been removed few months ago, but we reverted the change for an undetermined amount of time to better enable access to critical government sites sharing COVID19 information."

Since it was referenced as "undermined amount of time", is there anything currently on your roadmap/release schedule in regards to removing support again? I have some cutover decisions I need to make and knowing if ESR for example will remove this support in 2 months may effect the direction of those. If you have anything to share, i'd really appreciate it.

Regards,

-Chad

I'm unable to add any of my Gmail accounts into Thunderbird.

When I add a Gmail account, it goes through the process of logging in via OAuth2 using the default configuration, and I get the pop-up. I enter my email address and password, and it brings me to the Google screen where I approve of giving access to Thunderbird (this screen: https://www.google.ca/search?q=google+account+permissions+screen+thudnerbird&tbm=isch&ved=2ahUKEwjtpY2M7I_3AhXHg3IEHaaPCOkQ2-cCegQIABAA&oq=google+account+permissions+screen+thudnerbird&gs_lcp=CgNpbWcQA1CVA1jjDmDED2gAcAB4AYABgwGIAbcJkgEDNi42mAEAoAEBqgELZ3dzLXdpei1pbWfAAQE&sclient=img&ei=jiFWYu2mCceHytMPpp-iyA4&bih=754&biw=1600#imgrc=ZNXSyYRJ67bY4M).

When I hit Allow, the pop-up closes, and then Thunderbird comes back with "Unable to log in at server. Probably wrong configuration, username or password."

I have no problem adding Gmail to other apps; it's only Thunderbird that is having this issue. I've already tried a fresh install on a fresh profile, but it continues to fail.

Hello,

I noticed that a setting on the about:config page was removed: the "security.csp.enable" setting. I was using this setting to disable CSP to be able to load local JS scripts on some non-locally hosted sites, for debugging and development, work related purposes.

Was this setting really removed? Is there a way to disable CSP on Firefox on the latest version?

Thanks! Gabriel.
