We write an SDK that needs to detect what subdomain a site is running on. For example to detect that app.foo.example.com.au and web.foo.example.com.au share example.com.au

In order to do that we check if we can set a cookie on `.au` that fails. Then `.com.au` also fails, then `example.com.au` and that succeeds

This is safe and fast and leaks no information not already available to any JS running in the page.

In most browsers this is fine. In Firefox it is also fine _except_ it logs a warning to the console that a cookie was rejected. This then causes users to open a support ticket with us in order to find out about "the error"

Is it possible for us to suppress this log?

So it looks like notifications stopped working with the lastest Firefox version 120.0.1. Specifically notifications functionality has stopped working for ForexFactory.com. The site says browser disallows notifications though the settings in the address bar indicate that they are allowed. This is also the case for other sites like MarketWatch. Wondering if there is a bug or my install is corrupted. Let me know if anyone else is experiencing this or knows anything about this. Thanks.

When printing a page to PDF, with headers & footers, the default setup shows the date in right footer. However this date format is in (for me) awkward US format . Is there a way to show the date according to system regional short date & time ?

info: OS: windows 10 pro

 date format: YYYY-MM-DD
 time format: hh:mm (24-hr)

FF: 120.0.1 (latest to date) FF about:config -> print.print_footerright = &D FF &D format: MM/D/YYYY, h:mm PM (12-hr)

cAPTCHA is recent problem in Firefox browser ... never before was it a problem. cAPTCHA keeps asking to choose an image but keeps on never verified ... I had to get Chrome browser to finally log in to a site I wanted.

Recently I´ve encountered problems with (mostly) accessing nba.com. I don´t get the resultbar. Today klicking on one of the menue items (Schedule) Firefix refused to load the page claiming "Not safe". As you can see I´ve accessed the page a number of times. /Leif Arvidsson

I couldn't find a category for Firefox accounts/Mozilla accounts, so this question will be posted in the Firefox forum.

TL;DR Is there any way to get in touch with someone at Mozilla who can correct a faulty notification email address for a Firefox/Mozilla account?

My best guess is that when I first created the Mozilla account, I used the Gmail address, and even after changing the primary and secondary email addresses for the account, the Gmail address still remains somewhere in some database in the backend and it can't be removed or changed by an end user. Is there any way Mozilla can fix this issue?

The full story

Today I received an email introducing the renaming of Firefox account to Mozilla account. The email was sent to my old Gmail address even though I've changed both the primary and secondary email address in my Mozilla account settings a long time ago.

Email notifications about sign-ins and/or changes that are made to the Mozilla account are sent to the correct email addresses that I've configured in the account. So the issue is with general announcement emails regarding Mozilla accounts.

I have not received the email about the Mozilla account renaming to the email addresses that are configured in the account. Somewhere down the line I will delete the Gmail account, but that will also mean that I won't get these kind of announcements and thereby risk missing important information regarding the account.

Fake MCAFEE SECURITY ALERT KEEP POPPING UP in the last 24 hours. How do I get rid of this? I do have McAfee and ran a scan. Scan results no virus. I do not want to lose the current tabs session that I have open, if possible??????

My regular profile has deleted all saved history, tabs, bookmarks, etc. This happened before and seems related to having private browings open. and to an update in progress or recent.

Opend a private window. Then noticed regular FF wasn't opened. I opened the usual profile and all saved info is gone. Also, my stuff to be synced is way out of date so can't restore from there (I always had sync up to date). My "backup" can't be opened to restore.

Where do I find yesrterday's info? How do I restore my session, bookmarks, etc?

Last time, I tried to follow directions I found soemwhere but the instruction werent clear at all and had to restore from a disk image.

Why is there stsill the private window deleting regular window?

Hello,

we have a BigBlueButton Server setup for our company. Until recently we used a TURN-Server to tunnel the UDP connections thrugh the firewall.

Due to performance issues we wanted to try and let the clients connect directly to the udp ports 16000 - 32000

In Chrome this works as expected.

In Firefox however when we set "media.peerconnection.turn.disable" to "true" FF does not find any WebRTC candidates. We checked the logs and it says there:

"relay only option is set without any TURN server configured" "relay/proxy only option results in ICE TCP being disabled"

But thats NOT true! The option "media.peerconnection.ice.relay_only" is definetly set to "false"

Tested on FF 115.5.0 ESR and 120.0.1

Does anyone have an idea whats happening here? Why doesnt FF even try to make a direct connection?

UPDATE: I just ran a test on our dev system. If we configure BBB so that it does not offer any TURN-servers, FF uses a direct connection. Sadly that is not possible, since we need the TURN server for external connections. When there are TURN-Candidates but TURN is disabled via FF config no connection is established at all. This definetly semms like a bug in FF, since the browser should still be able to simply try and connect directly.

Thank you for you support

Ok well i went to about config and tired off all the accessibility about the quick help bar and now my question is every time i try to go to google search and click on shopping no matter what item i am searching for I get a pop up at the the bottom i of the page every time i hit on shopping that say error update can not be added to this list or some thing like that. it was ok until the last update o of firefox and since i did that but am not sure why. doe not do it in Chrome just frefox. firefox is getting to the point b where i an thing king of leaving it. Thank you tried a scree n shot but it does not sty on long enough '

Hello, every once in a while Firefox on my Win 10 PC resets bookmarks, logins and saved tabs to ones that I used several weeks/months ago. I also remember that it once switched back to a newer instance a few days after switching to and older one. When I try to open the app, it also creates a new icon on my taskbar. This has happened around 4-5 times in the last year. Does any one have an idea what the problem might be? Thanks in advance!

Reopening https://support.mozilla.org/en-US/questions/1412054

As you can see from https://github.com/linuxmint/linuxmint/issues/577 this issue is caused by Mozilla not caused by Linux Mint as accused in questions/1412054

Can you be honest and address this?

I know this is likely to be a wont-fix resolution, but I'd like to confirm that.

So if a webserver has the extremely cautious content-security header:

content-security-policy default-src 'none';

Firefox will correctly not embed video from that same domain in web pages hosted by that domain.

Fine. Good. Totally right.

When the server sets the same flag on the media file itself, Firefox's media player won't play it in browser. Even if I directly open the URL as a user, signaling my user intent to accept the risks for the file, the default player Firefox creates uses the media file's content-security-policy FOR itself.

This means the media won't load, gives an unhelpful and incorrect error message about MIME types, and the only way to view it is to actively download it and view it in local media applications.

Now, given the risks of allowing exceptions in CSP, I will understand if the development team doesn't feel this is a safe change to make, and it's on website owners to prevent this, but I don't feel it's in keeping with the intent of CSP to prevent this case.

I normally have multiple FF windows open on multiple desktops. After a restart all of a sudden every time I create a new desktop, FF duplicates browser. If I open a new FF Window it will automatically appear across all open desktops.

Tried pretty much everything: Multiple restarts Cleared Cache Refresh Firefox General Settings changes

Any thoughts appreciated

Hello, I cannot get videos to go into full screen in FF as they used to before latest update. Tested on various sites. There are no controls shown on YouTube unless i either hide the taskbar or scroll down both of which is a nuisance. On some sites the task bar stays at the bottom which it didn't used to do. link text

In the latest Windows update Microsoft Edge has taken over my browser. Mozilla is the default browser but if I double click to open a page it automatically loads Edge. Is there anything I can do?
