The Firefox website is telling me that the Adobe Flash Plugin is a critical update. But when I click on the button to download it I get the message "413 Header Length too large" - so I am unable to download the update. I am using Firefox 46.0.1 on a Mac running OS 10.9.5.

That's an unusual message. It may mean that Firefox is trying to send too many cookies to Adobe's site.

Does it work any better to download from the following page:

https://www.adobe.com/products/flashplayer/distribution3.html

Scroll down to the first table and look for the line that has Mac for Safari, Firefox and Netscape Plug-In.


If you need to clear Adobe cookies, while viewing a page on the site, try either:

  • right-click (on Mac Ctrl+click) a blank area of the page and choose View Page Info > Security > "View Cookies"
  • (menu bar) Tools > Page Info > Security > "View Cookies"
  • click the padlock or "i" icon in the address bar, then the ">" button, then More Information, and finally the "View Cookies" button

In the dialog that opens, the current site should be pre-filled in the search box at the top of the dialog so you can remove that site's cookies individually.

Then try reloading the page and downloading again. Does that help?
