I have telemetry (every checkbox under "Firefox Data Collection and Use") disabled, but noticed that the datareporting/archived directory contains telemetry files. Is this expected, or does this indicate a bug that shows that telemetry is being sent?

The file paths have the format:

<profile dir>/datareporting/archived/2025-09/<unixtimestamp>.<uuid>.main.jsonlz4 <profile dir>/datareporting/archived/2025-09/<unixtimestamp>.<uuid>.events.jsonlz4

I have all options enabled to save addresses and credit cards.

When I try to manually add a credit card, hitting the Save button does nothing.

When I use a credit card on a site, Firefox prompts me to save the card, I confirm that I want to save it, yet it isn't saved.

Kính gửi đội ngũ hỗ trợ Firefox,

Tôi hiện đang sử dụng iPhone 15 và đã cài đặt phiên bản mới nhất của Firefox. Tôi cũng sử dụng VPN qua ứng dụng Secure Access, được công ty cấp chứng chỉ trên thiết bị di động.

Trước đây, khi sử dụng phiên bản Firefox cũ hơn, tôi có thể bật VPN và truy cập trang web nội bộ của công ty mà không gặp vấn đề gì. Tuy nhiên, kể từ khi cập nhật lên phiên bản Firefox mới nhất, tôi không thể truy cập trang web đó nữa. Thỉnh thoảng, Firefox hiển thị lỗi "This Connection is Untrusted", có biểu tượng "Visit site anyway", và khi tôi nhấp vào, tôi có thể vào được.

Do trang web nội bộ của công ty đang sử dụng phiên bản SSL cũ và không thể thay đổi, tôi cần tìm một giải pháp để tiếp tục sử dụng VPN và truy cập trang web nội bộ như trước đây.

Mong đội ngũ hỗ trợ Firefox giúp tôi tìm cách khắc phục vấn đề này. Trân thành cám ơn

I joined a Microsoft Teams meeting through Firefox on the web on a Linux machine. When I tried to share my entire screen, I was asked if I wanted to share the entire screen in a Firefox pop up which I said yes. Then the "you are sharing your entire screen" came up, the sharing icon was red and the "stop sharing" button was red. See attached image. This all disappeared and reverted to the default state almost instantly.

Teams has a feature to "manage what attendees see manage what attendees see" where the meeting host can preview shared content before making it live.

I am concerned that the meeting owner was able to see my entire shared screen without me even knowing it through this preview.

Can someone help? Microsoft just sends you around in circles and I can't contact Mozilla.

Yahho search is on my home screen but not on my app list. I suspect malware. I use Bitdefender free for antivirus and scans sho no problem. I read that yahoo search can be hacked.What can I do

getting "SYSTEM WARNING" , " McAfee license expired " , " Trojan Detected " popup notifications continually after following a link on Linked In . Windows finds no threat in its quick scan . Popups occur even when Mozilla closed .

Why in the world am I seeing these tab Groups and Studies

After reading some posts on here I went to about:config and browser.tabs.groups.enabled was set to True. I changed it to false. I never set it to True and haven’t a clue to what Tab Groups are and don’t see any reason for me to have them. I only use about 4 tabs and have no use for any more. But I was noticing a Blue square box next to a tab and clicked on it and it said I had a Tab group which I deleted. Don’t know how a tab group was built, I sure didn’t ask for one and haven’t a clue what they are???

While researching this I seen something that about:studies could be the problem. I looked at it and it showed I was or had been in 4 studies!! All of the studies showed completed. I did not join or ask to be in any studies, what is Firefox doing signing me up for studies? I went to Privacy and Security and nothing under Firefox Data Collection and Use is checked including install and run studies. I have people’s secured data on here and if it gets out I could be sued!

I have run 3 full scans of different virus and all is clear. This must be something Firefox is doing without asking me for permission. I did find that browser.tab.groups.enabled was true, so I know FF must have done that during an update and I set it to False. Some post say FF will change it back to True?

What is really strange is the studies, it says they did 4 that are completed, yet it was not checked in the Privacy and Security section. Can't tell when as there is not a date.

These were the studies:

prefflip-push-performance-1491171•Complete hotfix-reset-xpi-verification-timestamp-1548973•Complete hotfix-reset-xpi-verification-timestamp-1548973•Complete pref-flip-screenshots-release-1369150•Complete

I would be grateful for some information on container behavior, i.e. I created "permanent" (as opposed to temporary) containers for sites where I want that site's cookies & site data preserved in a container, so I can click "Clear Cookies/History" (or "Clear... when Firefox closes) and the items stored in PERMANENT containers are left alone, while all else is deleted. "Clear ...." doesn't appear to be respecting the permanent containers I have set up precisely to preserve these sites' cookies & data.

I'm not sure what the point of Permanent Containers is, if not to preserve those sites' data, for the sites' later use when you set Firefox to Clear Cookies and Site Data whenever Firefox Closes (or Clear Cookies & Site Data with one click). I expected it to respect data in Permanent containers, as exceptions. Else why not just use separate Temporary Containers for everything? Why bother with Permanent Containers if everything is going to be deleted when Firefox closes, whether it's marked "Permanent" or not? Is there a solution for this? Thanks, -AnneF

I signed up & paid for Mozilla Monitoring Premium. I get monthly reports from then, but when I click on "automatically delete data from brokers," I'm asked to sign up for Premium again. Please help.

Good morning, I need to get off 2FA on my account Firefox kamilmian@gmail.com because by mistake I delete it in my phone and as I remember still have support phone in my configuration but 2FA blocks my option to login. Also I don't know where I have my codes, even after having acces to gmail account and phone. Please help.

Hello, When I try to use Mozilla firefox, using this rather than Google chrome I get the following warning from Malwarebyte: Exploit.PayloadProcess.Block, making me feel uneasy. Best wishes, Torbjørn Borgen Lindhardt, Denmark
