Hello,

I have been testing all browsers I use (Firefox, Chrome, Edge) on Cloudflare Post-Quantum Key Agreement to verify PQC support. They all support the X25519MLKEM768 hybrid scheme (i.e. Cloudflare web page returns "You are using X25519MLKEM768 which is post-quantum secure").

The issue: When I run the test in Firefox multiple times by doing repeated hard refreshes (Ctrl+Shift+R), quite often the result is "You are using X25519 which is not post-quantum secure". Sometimes the very first run after opening Firefox gives the X25519 (failing) result. "Often" varies. Sometimes it's around 10 fails out of 50 tests, other times it's 1 out of 50. It seems random.

I have read that sometimes networking equipment or even ISPs can be the cause of PQC requests falling back to non-PQC due to the long keys in PQC, but I do not see this intermittent issue with Chrome or Edge on the same computer/network/ISP as Firefox. I have not seen a single failure so far on those two browsers. The only variable I am aware of is the web browser.

I also tried connecting to a cellular hotspot as well as disabling my Norton 360 firewall and the results are the same as above.

Looking for help to resolve this issue. Thanks.

I can open gmail but it does not refresh. If I clear the cache it refreshes the first time only. Sometimes I get a message saying that my account is temporarily unavailable but I can access gmail with no problem on my iPhone, android tablet and with Google Chrome without any problems. Turning off the Advanced Tracking does not resolve the problem.

I changed the password of my Firefox account recently, which logged me out of my Firefox iOS app. When I'm prompted to scan the QR code to re-establish the pairing, nothing happens. When I choose to use email instead, I get "unexpected error". This happens every time I try to re-pair. Please help me sign in to Firefox iOS.

Just this week I found it was impossible to get to firefox browsing until I chose an upsetting blob as my profile. Is there anyway to skip this step or at least to change that blob to something that makes a more pleasant experience?

I received an email message from earthlink which included a verification code that I did not request. Earthlink support told me to change my password immediately which I did. Now when I open open Mozilla on me laptop, it requires me to put in the new password. How do I change the password/login that Mozilla uses to access earthlink?

since v150 came out ive been having an issue where i get a flash of white on start up if i have Homepage and new windows as Firefox home with a wallpaper... i have re-installed firefox and tested it as default and it still happens. seems the wallpapers have a delay till it displays properly.

I've been using Tabliss on Firefox without any issues, but immediately after updating to Firefox 151.0, a frustrating new loading delay started happening.

Prior to the update, new tabs loaded instantly. Now, whenever I open a new tab, the page sits on a completely blank screen for about 2 seconds before the Tabliss layout, background image, and widgets finally pop in.

Because this issue did not exist at all before version 151.0, it seems like the latest browser update changed how extension-based new tabs are cached or initialized, causing a new rendering bottleneck.

I read the article about having 50 GB of free VPN use after I updated Firefox today to version 149.0; however, I don't see anywhere where I can enable the VPN. I've checked in the "Customize Toolbar" section, and I still couldn't find anything. I don't understand, the article made it sound like I should have access, but I've also read that it's not out for everyone yet?

Why can't I open?

This is what I get: Server Not Found

Firefox can’t connect to the server at water.weather.gov What can you do about it?

Try connecting on a different device. Check your modem or router. Disconnect and reconnect to Wi-Fi.

After upgrading to 149.0.2 (64-bit), when starting FF or opening an new tab, the preferred URL is not loaded. It is configured in Settings/Home/New Windows and Tabs All previuos FF versions were OK with the same URl (https://search.yahoo.com/web/advanced)

Firefox is my browser but unable to access email page, "Access denied. You don't have permission to access .... on this server". Internet operating ok otherwise. Also, I have an old Windows 7 laptop which works fine - emails available and open ok.

I want to change the default download protocol accessing the mail server from imap to pop3. I went into the account settings & changed the default selection from imap to pop3. But the change does not take effect. Tbird still accesses the server using the imap protocol.

Здравствуйте! При установке параметра "Настройки - Основные - Открывать Firefox автоматически при загрузке компьютера" в реестре создается запись HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run - Mozilla-Firefox-E385C0CFD98A494C: "путь-к-файлу\firefox.exe" -os-autostart Что за параметр командной строки -os-autostart? На на сайте поддержки Mozzila не нашел, ни интернет не подсказал. Я понимаю, что это автозапуск Firefox при запуске Windows. Но что конкретно делает данный параметр?

So, forgive me, I'm a little frustrated right now, but I needed to move an Open Tab to it's own window, without the use of my mouse (yes, it's having issues right now), but: I used to do this by tabbing to the TAB in question and pressing <Shift> F10, which opened a context menu with a Move To sub-menu. Now the menu didn't have that option. see pic below. ...Yes, I was able to do the same via, File | New Window, and coping the address to it with Windows cut/paste and <Alt><Tab>. Still I would like to know how to get to the TAB context menu option without the mouse.

My cat jumped on my keyboad and Firefox detected 'unusual activity' She probably hit a combination of keys which lead to said activity. Instantly, I had to verify whether I was a human. I did, but really, it was my cat. Neither my cat, nor myself have bad intentions. I just thought Firefox security should know that these things might happen.

I hope that my cat's activity didn't compromise my account. Maybe 'unusual activity' should be less strict, though I do understand that Firefox must be vigilant. Maybe it would be a good idea to let users describe what happened, before sending Captcha?

I don't know what to do when February 29 is in my calendar, 2026 is not a leap year. I've found nothing to help me. I have the latest version if Thunderbird. Thanks
