Firefox used to save unknown files according to the save files setting. i.e. ask where to save files. Now if opens unknown files as text in a new tab.

How can the correct behavior be restored?

Alternately, can the Linux snap be fixed to allow saving of new file types? {The procedure shown in https://support.mozilla.org/en-US/kb/change-firefox-behavior-when-open-file is not present in the firefox 141 snap.

I am unable to enter or browse for a location to save downloads in the settings for this browser. The box to type in a destination does not allow me to type any text and the button labeled "Browse" does not pop up any additional window after I click it for me to choose a destination folder for downloads. I need to be able to alter these settings or will have to resort to using a different browser all together. I have been able to modify these same settings within Safari. Any assistance you can provide would be greatly appreciated!

On macOS the previous behaviour in Firefox was that the text content from the drag&drop was sent to the application I dropped to (and still works this way when doing so to the open application). But now Firefox downloads the image preview that I use to enable the drag&drop with into a temp folder, giving it a serial name. Is there any setting to revert back to the old behaviour? And if, not can you implement one please?

In Settings I have "Save files to" set to Desktop. Under Applications, I have PDF Files set to "Save File." If I download any other type of file, it is saved to the Desktop, as instructed. However, when I open Firefox, the Save dialog shows PDF files will be saved to Downloads. If I change it to Desktop, the file will be saved to the Desktop. Other types of file, as mentioned above, show Desktop as the default in the Save dialog. Once I set Desktop for a PDF file, it will be remembered until I close and reopen Firefox. It will then switch back to the Downloads folder, but again, only for PDF files. Why? This is something that has stated happening sometime over the last couple of months.

Windows 10 Pro 22H2, October 2025 patches installed. Firefox v144.0.2

I have the box checked 'Always ask you where to save files' but Firefox saves them to the default folder which I can't delete. it's a real pain in the a** to have to go back and move files. How can I change this?

Hi

Recently, I have been testing the functionality of my website using Puppeteer, but I found an issue with the file names when operating the Firefox browser through Puppeteer. When the user clicks the download button, my JS code generates a series of special file names. However, when I use Puppeteer, the file names seem to be truncated. Additionally, I have configured the BIDI protocol while using Puppeteer.

For example: When I manually open the firfox browser and click download button, the file name I get is ANTLMonitoring_MRBTS-530377530377530377_Wroclaw_class._2!__________+-=~,*@#$^&*()￥'.{}[]*;中文Приве..*TEST_123_20251028-0409.csv But when I perform the same steps using Puppeteer, the downloaded file name is ANTLMonitoring_MRBTS-530377530377530377_Wroclaw_class._2!__________`+-=~,_@#$^&_().csv (puppeteer)

Comparison: ANTLMonitoring_MRBTS-530377530377530377_Wroclaw_class._2!__________`+-=~,_@#$^&_().csv (puppeteer) ANTLMonitoring_MRBTS-530377530377530377_Wroclaw_class._2!__________+-=~,*@#$^&*()￥'.{}[]_;中文Приве.._TEST_123_20251028-0409.csv (Manual)

In both manual testing and Puppeteer testing, I used the default browser configuration. The operating system tested is Windows 11, and the browser version is 144.0 (64-bit). Can anyone help me with this issue? Thank you very much!

Bonjour, Comment forcer Firefox à toujours ouvrir un fichier .msg (outlook classic), au lieu d'avoir la fenêtre qui propose d’enregistrer (par défaut) ou bien d'ouvrir avec Outlook (mon choix) ? Merci.

When I do "save as " action for an image in the browser it opens dialogue window to save selected image. Unfortunately it displays files and folders in some random order, rather than my preferred order (sorted alphabetically by name, followed by sorting by type).

I can see no rhyme or reason to the way Firefox lists files and folders in the dialogue window, so every time I am saving an image I have to sort things by name and type before I can find what I want.

This is not permanent so I have to repeat this action every time I save an image.

How do I, please set application preferences? to make this setting permanent?

I was for reason having to default to LibraOffice and I really did not like that. I switched to FireFox so that I can open files through this browser instead. For some reason I download the files and it should take me to view the file in FireFox. I cannot view it at all. I wanted to be able to view the files in FireFox and then I can sync it with Google Docs and then open some of my files into google docs and I do not have to deal with LibraOffice. Why can I not view my files?

What follows describes what I think is an annoying bug, and as I'm writing a draft of the bug report, I thought I'd post it here first to make sure it's understandable, and if possible to get others to confirm the bug.

In Tools - Settings - Files and Applications, with the following settings: - Always ask you where to save files is ON - What should Firefox do with other files? is set to Ask whether to open or save files

If a file type is not defined in the Applications list/grid, Firefox 140.4.0esr displays the Open or Save box (only Save for .exe files) If you click Save, FF opens a save window according —logically— to the path defined in Tools - Settings - Files and Applications - Downloads, so - The list of files shown to the right is correct, - But the path shown in the toolbar above it is wrong (> ComputerName > C:\ > in my case), - And the selected folder in the navigation column to the left is also wrong (ComputerName in my case)

and that always throws me off.

The bug appeared before FF v140.4.0

Test downloads - Go to https://openexr.com/en/latest/test_images/TestImages/AllHalfValues.htm and click the link below the AllHalfValues.exr title - Go to https://www.picsellia.com/post/tiff-tag-image-file-format and right-click on one of the pictures at the top, select Save Image as from the context menu.

Please post a brief message below to confirm or invalidate my finding. Thanks!

Hello, Firefox won't save my download history between sessions, history is set to remember. I tried doing the refresh on the installer and even reinstalling firefox and deleting all mozilla folders in %localappdata% and %appdata% before reinstalling. it just forgets all downloads once I close firefox.

Although I have checked "Always Ask" to specify my download location, duplicates are still being saved in "Downloads". I recently "upgraded" to Windows 11 but do not know if it is connected. FF version 138.0.3 (64-bit). How can I prevent this please?

Hi — I used to be able to option-click (on a mac) a link in a firefox window to download the linked file directly to my selected downloads folder. This has seemed to stop working. Can you help me get it going again?

Many thanks, Mark
