Firefox Community Forum

I have DuckDuckGo as the search engine in my Firefox Browser. When I type a question in the screen box the words automatically populate in the address bar. How to fix?

I lost all my data after installation of new firefox. I have lots of important data in that profile.

I forgot the password to sign in and when I reset, a new profile was created for me and all my data are gone.

Now, I even know the original password. I did not know, I will lose my data. How can I get my data back? Please help.

I changed ma mozilla acc password and when i try to log in with new password on mobile "unknown error" occur. I can login on desktop with same password just fine. What to do?

Over the last week or so my personal websites (such as Banking, Amazon, Facebook, etc.) suddenly started asking for (text or email) verification to sign in successfully. This only happens after a restart. (Sometimes I run a 'restart to untangle some glitch - but some Windows updates do a restart automatically.) And I have to go through all the verification stuff again! VERY ANNOYING!! Some MS tech this morning had me uncheck Cookies and other data in the Privacy and security category. But that didn't help. I just did a restart and AGAIN my bank(s) websites asked for a texted CODE. So did Facebook, and Amazon. Once I complete the CODE requirement it stays good until the next restart. And when I went to change that "cookies" option was nowhere to be found (to change it back) In SETTINGS>PRIVACY & SECURITY - NOW shows just the green button and box that says "STANDARD". I don't want or need this annoying added verification on every site that I use daily. I don't know exactly how or when this started...(maybe about a week ago).

I've started getting Virus/Trogen warnings from McAfee popping up every few seconds on Firefox. There was a McAfee file on my Acer desktop but Not installed. Windows Defender and Malwarebytes do not detect a Virus or Trogen. Is this a SCAM by McAfee to get money from me? I cannot delete the McAfee install file as it says it is in use!

Issue: When Firefox starts after a system reboot, it starts on the incorrect desktop. This seems to be off by one; that is, I have Firefox assigned to Desktop 3 (using the Dock icon's Options menu). Under normal operation, it starts on Desktop 3, but after a reboot, it seems to start on (more recently) Desktop 2 or (earlier) Desktop 4. Unsure about what causes it to prefer 2 vs. 4.

This seems to happen after I've shut down (quit Firefox normally, shut down without reopening windows on login, power goes off, power on, log in, then click on the Firefox icon in the Dock) or after a system update (which reopens windows on login for me after rebooting and installing the update). It does not seem to happen after a Firefox update or after quitting Firefox normally and then restarting it from the Dock icon right away.

Pretty irritating, as I have major applications assigned to specific desktops, and Firefox is the only one that seems to forget which desktop it should be on.

Details:

Firefox 150.0.3 (aarch64):

• Settings > General > Startup > Open previous windows and tabs > TRUE (checked)

macos 26.5 (25F71) Tahoe:

• Settings > Desktop and Dock > Mission Control:
• ---> Automatically rearrange Spaces based on most recent use: FALSE
• ---> ...switch to a Space with open windows for that application: TRUE
• ---> Group windows by application: TRUE
• ---> Displays have separate Spaces: TRUE
• Dock > Firefox application icon > [Right Click] > Options > Assign To > This Desktop (i.e., Desktop 3)
• Apple Menu > Shutdown > Reopen windows when logging in: FALSE

MacBook Air M4 2025 24 GB RAM:

• No external displays connected

I get REAL tired by the amount of resources Firefox eats up with each open window. For whatever reason, having multiple windows open prevents Facebook from loading. I'll get 1 story and a "shorts" bar but THAT'S IT. Even clicking the story to rate or comment does nothing. If I start to delete windows; it will decrease the memory usage and then it will open.

However, I DO NOT WANT TO CLOSE MY WINDOWS IN ORDER TO OPEN FACEBOOK! Firefox should not be eating up that many resources. The open windows are of text and/or picture archives. There is no sound or video playing in the multiple windows open. My system literally has 128 gigs of ram memory so it seems very odd to me that Firefox is using between 11-13% with nothing running in the 15 windows I have open.

I've noticed for awhile that when exiting Firefox (currently 150.0.3) open tabs no longer close. When I re-enter Firefox (new start) I no longer get my home page. I've tried all key combination of exiting as well as the X. I searched this community and WWWeb and found nothing usefull.

Thank you for your attention to this matter. Rodney

I frequently need to access logs in HTML format from a particular application. I find Firefox more comfortable for this, so I visit the parent path directly in the browser. However, the default sort order is by name; since these are logs, it's more useful for me to list them by last modified time. Is it possible to make this sort order the default when visiting file:// paths?

I've attached an image of what I typically visit for completeness.

Thanks.

После недавнего обновления браузер перестал открывать сстраницы или открывает их очень медленно. Я очистил кеш, отключил производительность и ничего не помогает. Как решить это проблему? Пс. Хром работает отлично на этом же ПК.

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?

Firefox dropdowns, menus and popup menus do not appear after resume from suspend on Ubuntu 22 or 24 This has been happening for only the last few weeks. Even dropdowns on web pages do not appear. I can click the dropdown and cursor down then hit ENTER to change a dropdown's value but I cannot see anything while I'm doing it. On the menus, I can use hotkeys if I remember them but the menus themselves do not appear. Right-clicking to get a context menu also does nothing but it behaves like it did. If I right click something, nothing changes on screen but if I then click another link or button, the first click is swallowed to dismiss the non-existent popup.

Other apps on the system work fine including Chromium browser.

This only occurs if I start Firefox then suspend the machine and then resume from suspend. After resume, the menus, dropdowns and popups no longer appear.

I am running Ubuntu 24.04.4 LTS on a Dell Optiplex 3050, Core i3-7100x4 , 16 GB ram, Intel HD graphics 630 (KBL GT2), Gnome 46, Wayland windowing system.

I tried Firefox safe mode, clearing the caches, etc. Nothing worked.
