When I try to File > Save As on an .FLV movie, Firefox automatically changes the filetype to .mp4 while Chrome for instance retains the .FLV file type. I wanted to see why this is and how it can be fixed to work similarly to Chrome. Thanks.

Do you have an extension that allows to save FLV files?
FLV files are always played by a Flash player and usually can't be saved directly.

Such an extension may be doing the conversion or renaming of the file.


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

So if I went to www.mysite.com/sample.flv, loaded the page and went to File -> Save As in Chrome it will download the FLV. If I do that in Firefox it actually saves as an .mp4 instead of an .FLV.

Just to clarify you are saying that Firefox does not support the saving of FLV files from a website in the way I outlined above?

If that file is an FLV file then Firefox should save it as such and not change the file extension.
