Firefox Download Window Missing

firefox.pessimist953

After my browser automatically updated to 157.0, when attempting to download files on MacOS 27 (Golden Gate) the download window does not populate but a .part file appears in the default download location.

Hello,

To fix this, click the Apple menu, and select system settings. Next, select Privacy & Security, and scroll down and select "Files and Folders", then look for "Firefox" in the list. If it is there, make sure the toggle switch next to your Downloads folder is on.

Next, open Firefox and go to menu > settings > general, then scroll down to the files and applications section, then under downloads, select the option to "Save files to" instead of "Always ask you where to save files". After that, click the choose/browse button and re-select your downloads folder.

Lastly, you can try clearing your download history. To do so, go to menu > help > troubleshooting information, then under the application basics section, find the Profile Folder row and click Open Folder. After this, close Firefox. Then, in the finder window that is opened, look for a file named handlers.json and rename it to something like handlers.json.old or move it to another folder. After that, relaunch Firefox.

Oh, God bless you! Thank you so much.

Unable to Download Outlook Attachments After Upgrading to Firefox 157

Hi Firefox Support Team,

We recently upgraded Firefox to version 157, and since the upgrade, users are unable to download attachments from Microsoft Outlook on the web.

The issue started immediately after upgrading Firefox to version 157. Before the upgrade, downloading Outlook attachments was working normally.

Issue details: - Browser: Mozilla Firefox - Version: 157 - Application: Microsoft Outlook Web - Issue: Unable to download/open attachments from Outlook - Impact: Users are unable to download email attachments - Occurrence: Started immediately after the Firefox 157 upgrade

Could you please investigate whether there is any known compatibility issue or change in Firefox 157 affecting Outlook attachment downloads?

Please also provide the recommended workaround or fix. If there are any Firefox settings, security policies, permissions, or configuration changes required to restore attachment downloads, please advise.

We would appreciate a solution as this is impacting normal business operations.

Regards, Sunai
