Prior to update 125.0.1 corporate intranet users could download PDF files from our Line of Business applications / Webpages. Today after the latest update the PDF files download but are corrupted. The site was added to the trusted webpage without improvement.

Adobe Acrobat Reader could not open ********.pdf because it is either not a supported file or because the file has been damaged

Hi! On the latest version Mozilla Firefox 125.0.1 when i download .docx files i get the message 'File not downloaded: Potential security risk.' I select Allow download and the file downloaded can't be opened.

Thanks!

Quick background: I live in the US. I wiped my computer while traveling in the Netherlands. I installed Firefox while in the Netherlands. I quickly noticed that the default language was Dutch. No biggie, I looked around and "managed language" to English in the Firefox settings.

The problem is that Firefox is still stuck on Dutch mode. Even the spell checker is stuck. Internal messaging is stuck (e.g. the messages on the bottom of the page while loading a site). I just went to DuckDuckGo and it defaulted the page to Dutch.

I understand that I could reinstall Firefox while I am at home (US). But I think this is a bug. The browser should be able to switch languages in the settings, etc.

Let me know if I am doing it wrong.

I'm trying to migrate to the newest version of Firefox on an old installation of Fedora. I've downloaded and unpacked the installation files but can't identify the installer. All I probably need is the name, as I know how to make it executable and run it once I know what file it is.

For the past week, my browser does not auto-update. I have to download the update and re-download the browser.

I went into the settings and found the update section and when I clicked "Check for Updates", it kept saying "failed to check for updates". I tried with my proxy-settings on with VPN on, proxy-settings on with VPN off, proxy-settings off with VPN on, proxy-settings on, with VPN off.

This is in my personal laptop, where I am the only and admin profile.

My Firefox used to to auto-update but now it keeps saying I need to download the update, but my browser can't even tell if I have the most current version or not.

I am currently running Firefox on High Sierra 10.13.6 and have been advised that that OS will soon no longer be supported. I did have an option to do an update to ESR 115.1 in my Firefox app, however I was not home for a few days and when I returned planning to do the update it was no longer available. Now it just says my Firefox is up to date with 115.0.2... how can I get the update to the ESR 115.1? Thanks!

Hi, I keep getting this error when I try to download any extension. I also get an automatic download fail as soon as I try to download anything. I have tried several solutions such as changing privileges to reinstalling firefox entirely. I have checked other browsers on my computer and it is just firefox.

Can I download Firefox and save it to a flash-drive instead of installing it? The computer I need it on has a new install of Windows 7 with IE and it will not browse.

Prior to getting some desktop PC upgrades that required a new install of Windows 11 and a new install of Firefox, I backed up my entire PC (yea!).

Now that I have re-installed Firefox, I see that I have none of my saved bookmarks and so I want to restore the Firefox profile - all of it or at least the bookmarks.

I have tried following the Firefox instructions for this, but am apparently not doing it right.

I can't seem to locate the bookmarks file, for starters, in my backed up files. I find the profile but I don't find anything like places.sqlite.

Can someone help me so that I am locating the right (and complete) files, copying them correctly, and then switching to the new/old profile correctly?

Thanks in advance.

I want to create a link in the bookmarks toolbar to easy check and update firefox In chrome I can do that with creating a bookmark to: chrome://settings/help In edge I can do that with creating a bookmark to: edge://settings/help I have search for, but cannot find the equivalent in firefox

I am using a Samsung Chromebook Pro V2, running Debian, and installed Firefox using the Flatpak command "flatpak install flathub org.mozilla.firefox". The Firefox icon appears in the Linux apps group and I have opened Firefox using that icon.

How do I get links in my Linux apps to open Firefox and take me to the URL?

Thank you and Happy New Year, Abe

I'm having a problem with Win 11 that will likely require that I reinstall the OS. I decided to move most of the data in my User folder by right clicking and changing the drive from "C:" to "E:" in the Locations tab. Firefox was closed as a I did this, it worked fine, and then I restarted the PC. Upon opening Firefox none of the extensions are working and I'm not sure what to do.

Hello.

Lately i found strange bug in FF 119.0 (ppa - deb, not snap version), ubuntu 23.10 I can't download any file to mounted ntfs volume. Firefox instead creates thousands of empty files. Once it was 10001 or 10003 other time it was 20000 of files. I tried private-window, no change. I have removed all add-ons - no change.

For example i was trying to download https://fedorapeople.org/groups/virt/virtio-win/direct-downloads/stable-virtio/virtio-win.iso and i ended with (only few last lines):

-rwxrwxrwx 1 root root 0 2023-10-27 22:23 spice-guest-tools-latest-9989.exe -rwxrwxrwx 1 root root 0 2023-10-27 22:23 spice-guest-tools-latest-998.exe -rwxrwxrwx 1 root root 0 2023-10-27 22:23 spice-guest-tools-latest-9990.exe -rwxrwxrwx 1 root root 0 2023-10-27 22:23 spice-guest-tools-latest-9991.exe -rwxrwxrwx 1 root root 0 2023-10-27 22:23 spice-guest-tools-latest-9992.exe -rwxrwxrwx 1 root root 0 2023-10-27 22:23 spice-guest-tools-latest-9993.exe -rwxrwxrwx 1 root root 0 2023-10-27 22:23 spice-guest-tools-latest-9994.exe -rwxrwxrwx 1 root root 0 2023-10-27 22:23 spice-guest-tools-latest-9995.exe -rwxrwxrwx 1 root root 0 2023-10-27 22:23 spice-guest-tools-latest-9996.exe -rwxrwxrwx 1 root root 0 2023-10-27 22:23 spice-guest-tools-latest-9997.exe -rwxrwxrwx 1 root root 0 2023-10-27 22:23 spice-guest-tools-latest-9998.exe -rwxrwxrwx 1 root root 0 2023-10-27 22:23 spice-guest-tools-latest-9999.exe -rwxrwxrwx 1 root root 0 2023-10-27 22:23 spice-guest-tools-latest-999.exe -rwxrwxrwx 1 root root 0 2023-10-27 22:23 spice-guest-tools-latest-99.exe -rwxrwxrwx 1 root root 0 2023-10-27 22:23 spice-guest-tools-latest-9.exe -rwxrwxrwx 1 root root 0 2023-10-27 22:23 spice-guest-tools-latest.exe

I can download the same source files to the same location with other browsers without problems. Thank You for Your help!

I have a slight problem. I'm currently using Firefox 116.0.3 and it seems that it can't update. The automatic updating will run, and then it will fail (this is all the time when using Firefox). It will recommend me to download the newest version from the website, but then the CDN will and I will be presented with the "connection was reset" error. This happens both on my Windows 10 and Windows 11 machines. Both are running Firefox 116.0.3.

Funnily enough I tried to see if I could download the newest version on Edge (Chromium), which it could but the version I got from the website was the same version I have now. I wonder if this is something to do with my region as I'm based in China and I'm aware that some software can have...problems.

Also, when trying to download version 122.0, it is fantastically slow and will often fail to complete.

Is there anything that could be suggested as I really don't want to use Edge.

Recently Firefox always has the error "failed to check for update". I have tried restarting my pc and running as admin. I am on windows 10.

I have been able to manually install the latest version by installing it over the top of my current install, how can I fix the error to be sure that my browser will auto update?

Thanks

It has been observed that when a user uses the Firefox browser and tries to download a DDD file, the file format is .pdf instead of .ddd. In the devtools, it was observed that the content-type is text/plain in the response to the request. I changed the content-type to application/octet-stream, but the error still persists

After a crash earlier today within my 32bit install of Firefox, I upgraded to the 64bit version. Since then I have not been able to play videos from sites that utilize DRM.

I have tried the following:

1. Check and Uncheck "Play DRM content"
2. Check for updates while in the addons related page.
3. Checked my hosts file which is blank
4. Stopped my AV and attempted to update as well as Enable/Disable Play DRM
5. Get a 404 when attempting to go to "redirector . gvt1 . com" site.

When I looked in my profile directory, I noted that both the "gmp-gmpopenh264" and "gmp-widevinecdm" directories are empty. I found and downloaded the most recent openh264 dll for windows 64bit. Firefox continues to say "OpenH264 Video Codec provided by Cisco Systems, Inc. will be installed shortly." I have not found the most recent wildevine version so I have not tried to update it manually.

Could there be something squirrelly with my user profile that needs to be rebuilt? (I can export the bookmarks, etc) The 32bit Firefox crashed with no messages while watching a live YouTube stream. I just installed over without uninstalling the previous version. I was afraid of losing my current settings. The crash caused my "previous session" to be lost.

Hello, please is there any chance to add Firefox download for Linux and aarch64 platform to the download list? The attached image shows that you currently offer a binary package for the aarch64 platform only for Windows. Thank you.

I am running version 125.0.3 (64-bit) on Windows 11, and I can't check for updates and have to manually download each new version after given a popup telling me that the latest Firefox update couldn't be installed. I've tried restarting the computer, tried running the Mozilla Maintenance Service, and installing the latest updates for Firefox and Windows 11. Nothing I've tried has worked, and no other help article has helped me thus far.
