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.

My C drive needed replacement. I reinstalled Firefox and copied the profile from the old C to the new C. That did not work. I uninstalled and tried again with the report back that the files names were too long. The old disk is still in the computer with a new designation. I tried installing again to the old drive that has all the original data. That did not work. (I do have a saved copy of the profile) I'd like all my settings, but at least the bookmarks. Firefox doesn't seem to have importing from another Firefox, so I can do that. How do I import bookmarks from the Firefox on my old disk. Help would be appreciated. Thank you

On the ribbon go to the Annotate Tab. From there go to the Text Palette. Click on the arrow pointing at the corner. It brings up the Text Style box. From there replace all of the texts with ther warning icons showing or. Click on ‘Add’ to add new fonts. Font Xs

I'm having the following problem in my web application and it only occurs in the Mozilla Firefox browser: "Content-Security-Policy: Page settings blocked loading of a blob resource: https://sitename (“frame-src”).”

I am using the SheetJs library to export a .xls file in javascript, when generating the file using the writeFile method, the mentioned error occurs.

I've used a private browser, removed all extensions, cleared cache, etc.

whenever I am on Amazon.com the search window constantly fills with "solo con tu pareja," a movie I once watched. When searching for an item and even when trying to buy something the search window constantly fills with this phrase. This only happens using Firefox browser I've tried clearing cache, re-setting, etc. and while I got it to stop once, as soon as I re-started computer the problem came back.

On our online application we are facing with some strange behavior for a small percentage of our firefox users (<1%).

When doing oauth2 authorization, after generation of the authentication token we redirect to another platform but we are detecting that for a small percentage of Firefox the cookie (my_auth_cookie) with the auth token is not present.

GET: https://www.mywebsite.com/application/login Response:

new location https://www.mywebsite.com/otherapplication/redirect

set-cookie: my_auth_cookie expires=Mon, 04 Dec 2023 13:49:15 GMT; domain=.mywebsite.com; path=/; secure; samesite=lax; httponly

      2. GET https://www.mywebsite.com/otherapplication/redirect

          Set-cookie: mycookie: value

          Host: www.mywebsite.com

In cookie tab I see my_auth_cookie (value: xxxx, domain: .mywebsite.com, expires: Mon, 04 Dec 2023 13:49:15 GMT, httponly: checked, secure: checked,SameSite: Lax, partitionkey: empty, Priority: medium

I’ve tried to replicate but without success (with multiple extensions, including multi-account containers), with multiple configurations of Total Cookie Protection.

Again, this only seems to be happening to a very limited number of firefox users but for these, it happens 100% of the time. We see it occurring for versions 119 and 120 but now and then for older versions.

Feedback reports no extensions&addons.

Any ideas on what we could be dealing with? Any help would be greatly appreciated.

I've read a few old threads and checked both the DRM setting and the "-Vine" as they recommended. Still no luck getting it to work. I'm posting yet another thread about this here because I'm getting a bit frustrated, frankly. Firefox is my favorite browser by far, I just wonder if anyone has found another way to fix this.

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?

Hi All,

Deploying few  features for a system using firefox browser. 

In once scenario, on a user action , showing an alert box and redirecting page to new URL. On this , new page is loaded and after loading the page, the alert box disappeared This is working in my last system configuration, which is MozillaFirefox-78.9.0-112.54.1.x86_64

I am upgrading the system now I am using MozillaFirefox-115.3.1-150200.152.111.1.x86_64 In this configuration, the previous alert box is not removed when page is reloaded Any configuration/setting has to be done in firebox browser to automatically close the alert box?

Every day. Videos won't play. sometimes one restart of firefox will fix it. sometimes multiple restarts are required before it'll work. The loading bar at the bottom of the video (on the seek bar) indicates the video is loading but it won't play. There have been times where I have disabled every single add-on and it would not work. Add-ons do not seem to be the cause. I have tried it in a private browser window with no joy. I have refreshed firefox, I have uninstalled and reinstalled it. I have tried disabling my antivirus. I have tested videos on websites in other browsers with no issue. The issue seems to be with the video player itself. overlays seem unaffected, I can use the seek bar and it shows the captions. I have tested different websites including Youtube, Vimeo and Steam. I tried many tens of times to get it working today to no avail. finally when I closed nearly all my tabs, the video worked (but I had also opened TOR and run avideo in that), I am not sure if this is the cause. If the cause is having multiple tabs open, this is an issue for me. I have a learning disability and likely ADHD and I have a set of tabs as my homepages so I don't forget things. If It's not the mutliple tabs, then what else can I do?

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 '

Sling TV audio is intermittent ONLY with Firefox. I've tested the site with Edge and Chrome and both work. I prefer to use Firefox for other reasons. Is there settings I can change to fix this? Please help as I see that others have posted this same problem.

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

So I just picked up a new laptop (ASUS Vivobook 16x), and everything is fresh on it. Additionally, this only affects some video content in Firefox, with Edge browser unaffected. In brief, what is happening is that within a couple hours of having the browser open, certain video content stops working, specifically Twitter/X videos just spin, YouTube previews stop working, and videos continually load. Netflix videos continue to work, but hover previews stop functioning. I even check the 'Stats for Nerds' on YT and it shows 0 KB network activity in Firefox.

I've tried every basic action I can think of:

• Turning off extensions (only use Ublock and Bitwarden)
• Browser Refresh (x3)
• Reverting from 120.1 to 120.0, and now 199.0.1
• Clearing the browser cache
• Reinstalling NVidia and Intel Drivers
• Running in Safe Mode

Only by doing a refresh or completely closing/opening the app gets videos to function again. This doesn't affect the old laptop or my desktop, which makes me think it's a rogue driver--but then why would Edge function without error over the same period of time?

Are there any settings to play with in the browser that can help diagnose?

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
