Can anyone tell me how to blacklist incoming emails from selected addresses?

I can get T-bird to send unwanted emails to the "Junk" folder, but there are some that I would prefer not to even show up on my end, but rather delete them before they even get here (Facebook being the prime offender - hundreds of people I have never even heard of sending baby photos, etc.).

I contacted my ISP and was told that I needed to do this from the T-bird end. I cannot find anything in the Support section that addresses this problem. Thank you, Wolfgang

You can see from the first image that I had unchecked the "Block pop-up windows". But then if a page wants to pop up the windows like running "for(let i = 0; i < 24; i++) window.open("about:blank")", the result will be the second image. Firefox still keeps blocking despite my setting. And there is no even option like "allow the pop-ups" in the Options menus on the info bar.

Hi,

I'm blocked because for my company i have to make a GPO that will setup the default handler for pdf files. I picked up different codes on internet but it went the same way for all of them, it didn't work. Im pretty sure that's not a GPO application issue because actually all the others setings are working perfectly.

The json code was paste on the Handlers settings as u can see in the attachement.

Hopefully that i will find help there.

Cordially.

Hi,

On what port does the firefox extension update on does it use port 21? I need the extensions to be auto updating like set and forget knowing that my firewall is not blocking the required port

Thanks

I am on Firefox Developer Edition 120.0b9 (64-bit macOS). Using sites like whatismyip and whatismyipaddress, I am seeing that I have a VPN or Proxy enabled. When I use Chrome, I don't see this. I went through all the settings and turned off anything that could even remotely be related, and still get the same results. Does Firefox have a built in VPN that I am unaware of? Is there a way to turn it off?

Hi, I want to delete my acccount entirely and start fresh, I login to the website just fine, but when going to the "Delete Account" button I keep getting an "Incorrect Password" pop-up.

I've changed the password twice now, logged in just FINE, yet keep getting told I'm using the incorrect password when trying to delete my account.

I've tried on multiple different browsers now to delete the account and it's just not working.

I really wanted to swap over to Firefox but everytime I try, I get some insanely stupid issue that never ends up being resolved, I've found another thread from 2021 about this and they stated it never got fixed and they had to make a whole new email just to use the service.

The queries don't even reach the server. On Windows 10 I don't have this problem. Both have the server parameter set to https://192.168.1.x/dns-query/. I have tested versions 102.7.0esr and 109.0.

Hi,

I know how to turn on OS authentication to reveal passwords in about:config (signon.management.page.os-auth.enabled = true) But is there any way to turn this on in registry?

So I have two different accounts for one website. However one of them I use very rarely, maybe once in 2-3 months the other one i use almost daily. Therefore I have saved both logins in Firefox and I can see them in my passwords.

The problem is that whenever I try to access the website, Firefox auto-fills the "second" account, the one i only use rarely. What this means is that instead of me being able to just press login i have to delete the username filled in by Firefox and select the other one. So what i would like to do is to maybe tell Mozilla that I want it to use the other account for auto-fill.

My Windows Task Scheduler contains an entry called "Firefox Default Browser Agent". If I delete it, it returns. If I disable it, it re-enables itself. Can't be modified either. How do I turn it off permanently?

I already have telemetry and automatic updates both turned off.

In about:config default-browser-agent.enabled is set to false

After some basic research, it was suggested that the Outgoing Server should be set to Oath2 but I am unable to change this.

During my absence my house maid created a Google account for herself on my Firefox browser, which is confusing my browsing as it is also a default account. I wish to remove my maid's account but cannot find how. Please help. I am using Windows 10.

Update to the latest version Download Firefox

I just downloaded FireFox because it's the browser that's recommended by the IT administrator for using the company proxy. I've set up the proxy settings but with the proxy set I cannot connect to any site.

I get this message in the browser window Unable to find the proxy server

Firefox is configured to use a proxy server that can’t be found.

   Check the proxy settings to make sure that they are correct.
   Check to make sure your computer has a working network connection.
   If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the web.

I've double checked the proxy settings and they are correct. I can connect to sites with other browsers to I have a network connection. My computer does not have a firewall set.

Also FireFox connects to websites when I disable the proxy. I've also confirmed with other colleagues that they are using the proxy so the problem is not that the proxy server is not correctly set up.

Can anyone help me troubleshoot?

Hello all, First of all thank you for the good quality of mozilla products. I am using mainly firefix and thunderbird on linux (Ubuntu) on all my computers, that of my children and of any friend I can convert to open-source computing.

I have done all possible documented actions to configure firefox for blocking pop-ups, including standard (permissions in privacy & security settings) and advanced (filter on autoplay parameters in about:config) options available. I keep receiving pop-up windows with unwanted videos, e.g. on my paid subscription to a local news website. See the attached screen capture, where I right-clicked on the pop-up window. You will see that a "digiteka" player keeps appearing and I never sollicited these videos. I hate this. It's not even pub, it's news, but when I'm reading an article I don't want to be bothered with other news that I'm not interested in. Plus, I don't want any unauthorised software like this digiteka player running on my computer without my permission. It's not a firefox module, it's probably silently downloaded over my connection with my news provider with no notice. I could go as far as blocking autoplay so the video will not start playing automatically, but I would like to completely block the apperance of such windows and any download of something executable on my computer. What could I do in addition? I there any way, other than stopping my subscription to this site?

Many thanks for your help. Patrice.

I have search separated from the url bar, and I have Firefox Suggest configured to only use history for tab completion. I've noticed a couple problems.

• Search is being prioritized over options in my history. I have the separate search box, if I wanted to search I would use it. If I type a single character I want the most common result from my history to be the result of hitting tab.
• I've noticed recently that I'm getting sponsored results even though I have them disabled. It's somewhat inconsistent, and I've only noticed it in one of my profiles. Specifically I am used to "w <tab>" taking me to weather.gov but I'm getting sponsored results for AccuWeather. I clicked the "feedback -> not interested" button but this is concerning that Firefox is ignoring preferences and there's a pattern of sending data to Google and AccuWeather despite me configuring the browser not to.

Am using FF 109.01 (64) and the latest Windows 10 (64) ver. I uses their Virus program.

With my bank security settings I have check marked to not use 2FA Bank home page asks for a security code anyway.

This has happened to me months ago and all of a sudden everything was OK. ... and now it has happened again. When I use Edge, Bank home page does not ask for a security code. This is the way I would like FF to perform.

I have phoned the Bank IT Help desk and they are bafflled. They had me try a bunch of acrobats but nothing works.

Obviously there is something in FF to tweak. I am using

I have searched and searched on internet, but no solution. I have used FF since it was a baby, and I want to stick with it. Thanks

I set a password to login to Thunderbird.

However if you simply press the cancel button on the login (keep pressing it when it re-shows) the email app opens and all emails are visible.

How is this useful? I put a password on it to make email inaccessable when i am away from my PC.

At present anyone who has acess to my machine can open and view all my emails.

thanks
