Firefox Community Forum

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.

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

Hi,

Please tell me exactly WHAT AI, WHERE that AI is, and EXACTLY what DATA is transmitted, on an option that's enabled BY DEFAULT on Firefox.

"Use AI to suggest tabs and a name for tab groups"

And the same question for ALL other AI features.

There is ZERO transparency on this issue, and I'm mightily disgusted that you feel the need to, by default, force share the EVERY WEBSITE VISITED with a third party AI system.

Has any body else found Firefox relay to be mostly useless? I put up with the annoyance for a few days and then had to get rid of it.

I did use it once to get past the id page for a purchase just to look at the freight cost. Too much, so the tab was closed straight away and the masked email did not leave my computer.

The problem is that signing up to new accounts or providing your email online is something that is done only very rarely compared to the number of times your email has to be used to login to an existing account but relay has to be in the way every time.

Just a hint to the developers, those accounts already have my email and they will never lose them. Also if I need to use my email to sign in, giving a mask email is not going to work very well.

Relay is a great idea if only it could determine the right time to get in the way.

Recently transferred from Chrome. My understanding was Firefox private browsing was supposed to work similarly to chrome incognito mode; once you close the browser, all local files are deleted and cookies are cleared.

However, with Firefox it maintains my logins. If I log into an account while private browsing and the close the browser, I’ll still be logged in next time I go to the website even if it’s days later (and I have never logged into this account in a non-private browsing window!)

I never had this issue using chrome incognito, so it seems to be a Firefox problem.

Is this just not something Firefox supports? Is there any way to prevent storage of cookies and private data?

If I were to delete my Mozilla account, would I be automatically signed out of both my Mozilla account and my Mozilla Support account across all devices?

Also, when deleting my Mozilla account, is any and all information related to both my Mozilla account and my Mozilla Support account deleted?

   DuckDuckGo Privacy Features: The Fire Button [duckduckgo.com]
   Ever wish you could wipe the slate clean online? Our Fire Button burns away traces of websites that you’ve visited (like cookies and website caches), browsing session information (like open tabs and URL history), and permissions you’ve granted to websites (like geolocation, camera, and microphone settings).

Having spent a frustrating weekend being unable to log into Coventry Building Society's online banking app, I phoned them this morning to be told they consider Firefox insecure and no longer support its use. The app accepts my username & password, tells me they are going to 'phone me with an access code' and then displays "Page not found". Anyone know of any other bank or similar who would believe Firefox to be insecure?

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

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.

With the change in the Privacy policy and TOU for Mozilla, it's been mentioned in several official responses that certain functionality will not be possible going forward without those changes.

If I never use suggestions, hints, or any mozilla services with firefox. Just what functionality becomes a problem that you need to change the "We will never sell your data" and the other equally disturbing "you grant mozilla a irrevocable non-exclusive royalty free right..."?

How about some clear transparency instead of the opaque non-specific statements you've been making?

Loyal users of firefox for the last 20+ years deserve better than this.

Oh, and why can't I remove the search shortcuts for bookmarks, tabs and history, I'd like to map those keys to something else.
