Firefox Support Forum

Embedded links in Outlook email on Windows 10 will not open automatically when the new email is first opened to be read if Firefox has been selected as the default Browser. This is a new issue !

The message is" if there are problems with how this message is displayed, click HERE to view it in a web browser " and then the Browser used is only Edge!

Restoring disliked Edge to be the default browser corrects the issue but Edge is a known tracking device.

Hello to everybody, My question: Opening local .mdb files (MS Access database) does no longer work in Firefox 120, but was ok in previous releases. The only choice is to save the file rather than onening it with MS access. Under Firefox settings/applications the file type .mdb does not appear. If I answer the question "What should Firefox do with other files?" with "Ask whether to open or save files" it has no effect at all. I expect to find an entry for .mdb files where to choose "always ask" as was the case earlier. Please help!

Still image quality good but videos are over-saturated in colour. Same videos in Chrome videos are not over-saturated. Many people have this issue but no solution in search results.

I tried to pay my Wells Fargo VISA bill online as I do every month. This morning it listed all my accounts correctly on the 'Accounts' screen, but when I clicked the options to transfer money, depending on the screen I was on, it gave a message "you do not have two accounts to transfer money from and to" (not the exact wording.)

I tried to use a different path to do the same thing, and on that screen it displayed the 'FROM' accounts correctly but the "TO" account area was blank.

I had to close Firefox, load Edge, and was able to transfer the money from the checking account and pay the VISA bill.

This has never happened before and I have done this transfer and pay operation every month for years. Something has changed in the browser and needs to be fixed.

I have installed Mozilla Firefox 120.0.1 on Ubuntu 22.0.4 server as a root user and can launch but when I login into another user the browser gives me the error message "Your Firefox profile cannot be loaded. It may be missing or inaccessible"

Please help me how enable Firefox browser for all Linux users

I have been accessing my Virgin media account for years from the Firefox browser. I like to access my email from Firefox. But now it won't work. However I can get into Virgin media straightforwardly from Microsoft Edge. I've tried clearing the cache (though I don't know if I did correctly) but it's made no difference to the Virgin problem.

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

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.

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 '
