"do this automatically for files like this from now on" is greyed out

Posted

The option to "do this automatically for files like this from now on" on my browser is greyed out.

It also not listed under General>Application.

It's a .rar file

One possible reason for that box to be grayed is if the website sent a generic "this is a binary file" content type for the RAR. I created an add-on to work around that problem, if you want to give it a try:

https://addons.mozilla.org/firefox/addon/content-type-fixer/

When you first it install it, the extension is snoozing (Zzzz button). Click the button to turn it on. From that point, all .rar files should be associated with the proper Content-Type, which is "application/vnd.rar". Any improvement?

Since the extension intercepts all page requests and downloads, it can slightly slow down browsing, so I suggest snoozing it until you find a site where you need it.
