Firefox Support Forum

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.

I've been unable to play amazon prime videos on firefox for some time now. It comes up with error message 'video unavailable'. I've followed all the advice on amazon website and google searches but nothing works. what do i do ? (this is on asus zenbook laptop) I've tried checking for updates on firefox and add ons, restarting Firefox, restarting laptop, clearing cache , checking DRM settings and deactivating proxy servers.

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.

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

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.

I use Google Meet multiple times a day for work meetings. After switching to Firefox from Chrome recently, I have noticed some persistent issues to do with audio from devices external to my laptop. I have a USB external microphone, a USB sound card that powers external speakers, and wired headphones that I use through the laptop's headphone jack. In macOS my default audio input is the external mic, and default output is the wired headphones.

The first issue that I noticed when using Firefox in meetings was that people reported an echoing effect on my audio. Audio from everyone else sounded fine to me. Changing my microphone source in Meet or in macOS did not seem to help, nor did disabling echo canceling in Meet. What did help was disconnecting the USB microphone completely. The impression that I got was that Meet was taking audio from both the USB mic and laptop mic at the same time, even though only the USB mic was selected. This has happened every time I used Meet.

The second issue that I noticed just happened for the first time today. (Note: I now have my USB mic unplugged until I can resolve the mic issue.) In macOS I had my wired headphones set as the audio output device. I joined a meeting, and I was hearing the meeting audio in my headphones and the external speakers (USB sound card) at the same time.

I've used Meet with Chrome for the last few years and never had this type of issue.

Something I have noticed that may be relevant is, when I open Meet in Chrome and go to the Meet settings, it shows my USB sound card and wired headphones as audio input/output options that I can select, in addition to the built-in laptop speakers. But when I open Meet in Firefox, the settings only show the USB sound card and laptop speakers for output - they don't show my wired headphones. FWIW, media.setsink.enabled is set to "true" already - I saw this mentioned as a solution in a similar question from 2022.

Is there anything I can check, or debugging data I can capture when this issue happens, which would help figure out the root cause?

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?

I am trying to zoom in and out on a webpage JUST the elements. I DO NOT want the text to zoom in or out when I do this. I was able to do this within the last couple of days here, but cannot remember How I did so..

Dear Community,

Been having a problem with downloading for about 2 weeks now.

I am doing a course in Ethical Hacking, and have been told to download an .ova file from the internet. The download is 8.5 GB.

However, it has failed on, now, 8 occasions. The nearest it has come, is it has downloaded 5.1 GB.

Could anybody recommend another tool to download files better and quicker? This course is now almost halfway through and I still have not managed to download the software. Any suggestions would be most welcome. Could it possibly be the case that my anti-virus, Microsoft Defender, is not letting the download through? If so, how could I switch the anti-virus off, please?

HOW DO I STOP the background from being black? I can't read the URL i am selecting to copy in the URL address box. In prior versions, the use systems color option used to work. Now it doesn't. Plus the pull down that shows up is the most god awful seaform green i've ever seen. I WANT MY SYSTEM COLORS BACK

This problem just started recently, where I can't unmount an external USB drive without getting this error message:

The disk "Projects" couldn't be ejected because "Firefox" is using it.

I hate to keep quitting FF just to unmount a USB drive - that means logging in again to various web accounts.

My only extensions running right now are Enhancer for YouTube, Grammarly, and Facebook Container.

What's preventing me from unmounting a USB drive?

Thanks!

I installed Firefox on a new laptop and synced it. The bookmarks all were transfered. But when I log into some websites they do not recognize the password, even when the passwords are correct and still work on my previous computer/Firefox brow’ for ‘Firefox.

Hi all, I had a firefox account years ago that i forgot about. Ive just switched from google to firefox by downloading ff and when i opened the browser it had all my old bookmarks and things across the top. I deleted that old account and signed into ff using a new email yet my old bookmarks remained. I then did and 'import' from chrome hoping it would overwrite the old things but it did not. So i am now with a new email / account stuck with older bookmarks i do not want, id like to have all my current bookmarks/passwords and the other things ...

What can I do about this?

Thanks

Downloading each page of a subscribed newspaper takes about 30 seconds. How do I eliminate the slow response? By the way, I deleted Firefox and reinstalled it. That fixed the problem only temporarily.

Thank you, Mike
