Firefox no longer asks what to do for each file by default
You are not prompted to choose a helper application or save to disk before downloading a file, unless you have changed your setting for that type of file, for Firefox to always ask what action to take:
Downloads panel automatically opens
Every time you start a download, Firefox will automatically bring up the Downloads panel by default, so you can experience minimal interruptions and easily find your downloaded files (to avoid having to close it several times, the panel won't show if there are multiple downloads in progress).
To hide this panel when a download begins, right-click on the downloads button 
, and uncheck the option .
Downloaded files are saved to disk
The files you download will be immediately saved on your disk. Depending on the current configuration, they will be saved in your preferred download folder, or you will be asked to select a location for each download. Windows and Linux users will find their downloaded files in the destination folder (this is usually the Downloads folder). They are not put in the Temp folder first.If you have security software installed on your system, such as an antivirus, it can scan any files you download. If you notice that downloading large files takes a while to complete, sometimes increasing the CPU usage, this is not done by Firefox, but by the security software.
Set a default app to open a file type
When you set an application to open files of a specific type in your Firefox preference settings, those files will open automatically, even files served by the website with content-disposition: attachment. The same applies to PDF files that are set to open in Firefox by default. This is a fix to bug 453455.
“Always Open Similar Files” and other Downloads panel options
When you download a file that can be opened with an installed application, you can add a preference to always open similar files, from the Downloads panel context menu for the file. Right-clickHold down the Control key while you click the file to see this menu item and other available options for that download. (The Always Open Similar Files option is also available for files listed in the Downloads Library window.)
The following options are available. You will not see some of these options for files that have been deleted, renamed or moved from the download folder.
- Always Open Similar Files: Make Firefox automatically open downloaded files of the same type with the system default application. (This option may be missing in some cases, such as files served by the website with the wrong content type, or executable files.)
- Show In Folder: Open the folder that contains your downloaded files and select the file used to open the context menu.
- Go To Download Page: Open in a new tab the page from which the file was downloaded, even after leaving the site or closing the tab.
- Copy Download Link: Copy the download link to share it, save it, or for any applicable use.
- Delete: Remove a downloaded file from your disk. It will appear in the list as File deleted.
- Remove From History: Remove a file from your list of downloaded files. The downloaded file is not deleted from your disk.
- Clear Preview Panel: Clear the list of downloaded items in the preview panel that opens when you start a download.

Frequently asked questions
The What should Firefox do with this file? dialog was a helpful way to see when something downloaded. How do I notice this now?
The Downloads panel will show automatically after you start a download.
I want to approve each download before it happens, is there a way to do this?
Firefox no longer shows the dialog by default because downloads are usually intentional. Having to click a second time for a download to start is usually unnecessary. Once a content type has been set up on the Settings page, you can change its action from Save file to Always ask. The steps are listed below under “I want to configure a different behavior for some files. How do I do that without the dialog?”
If you prefer to have Firefox ask you what to do with files that do not have an action defined on the Settings page, you can go to the bottom of the Applications section under What should Firefox do with other files? and select Ask whether to open or save files.
When you choose the setting Ask whether to open or save files, you will see a What should Firefox do with this file? prompt when you download any file that has no defined content type.
Why does Firefox keep asking me where to save files?
This will happen if you have configured your Firefox settings to always ask you where to save files. To check your download settings:
- In the Menu bar at the top of the screen, click and then select or , depending on your macOS version.Click the menu button and select .
- In the panel, find the Downloads section under Files and Applications.
See Change where downloads are saved for more information.
When I open a file with an application, why is it also saved to my Downloads folder?
Before Firefox version 98, files you opened in Firefox with an application were also saved to the system Temp folder on Windows and Linux, even though you may not have been aware of it. Firefox no longer saves files to a temporary folder because of the downsides to saving files in a location that is hard to discover. Instead, files are saved to the Save files to folder location shown in Firefox settings, in the panel Downloads section under Files and Applications. (Firefox will not ask you to choose a folder when opening files if you have selected the Always ask you where to save files setting, to prevent unnecessary interruptions.)
I want to configure a different behavior for some files. How do I do that without the dialog?
When you select Always Open Similar Files in the context menu for a downloaded file, it will set Firefox to always open that type of file with the system default application. If you want a different behavior:
- In the Menu bar at the top of the screen, click and then select or , depending on your macOS version.Click the menu button and select .
- In the panel, go to the Applications section.
- Select the type of file you wish to change and use the drop-down menu to change the download action, such as using another application to open that type of file or having Firefox always ask you what to do.
