Hello,

Can you please follow these steps and provide the value for the configuration 'browser.download.useDownloadDir'

1. In the Location bar, type about:config and press Enter. The about:config "This might void your warranty!" warning page may appear.
2. Click I'll be careful, I promise!, to continue to the about:config page.

Can you please provide the values for the following keys

1. browser.download.useDownloadDir
2. browser.download.lastDir

Thank you

You can try to delete the mimeTypes.rdf file in the Firefox profile folder to reset all file actions.

• http://kb.mozillazine.org/mimeTypes.rdf
• http://kb.mozillazine.org/File_types_and_download_actions#Resetting_download_actions

You can use this button to go to the Firefox profile folder:

• Help > Troubleshooting Information > Profile Directory: Show Folder (Linux: Open Directory; Mac: Show in Finder)

gnittala:

browser.download.useDownloadDir;  user set  boolean  false
browser.download.lastDir   user set   string   I:\Excel\Rampart\Monterrey Village

The browser.download.useDownloadDir setting as false would mean that Firefox needs to prompt you for download actions. I will suggest you to try the option of deleting the mimeTypes.rdf file as suggested by cor-el. Please try that and let us know if it helped in resolving the issue.

Thank you

I deleted the mimes.rdf file and it didn't help. I reset firefox on the troubleshooting page and it didn't help.

Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).

• Do NOT click the Reset button on the Safe Mode start window.

I started Firefox in safe mode and attachments still wouldn't download. I get a brief message saying "scanning an attachment" but then it goes away and nothing happens. As far as I can tell, nothing is downloaded, nothing is opened.

What really has me puzzled is that some days, it will work just fine for a couple of attachments, then it goes back to doing nothing. I assume it is a Firefox issue since I can still download email attachments on Chrome.

Hello,

Is there an anti-virus running on your machine? If there is one running can you please check its activity log to see if it is deleting any of the downloaded files.

Thank you

Is it a Yahoo! mail attachment? Common issue in recent weeks. Try:

• Clear cached files per Firefox will not download attachments - I have to switch to Safari to do that :(

• Copy the address from the Chrome address bar to the Firefox address bar, and bookmark that new address, and delete your old bookmark

Any luck?

Actually, instead of a bookmark, your home page address might be out of date, so you would need to update that. These articles have tips on that:
