Blank .mht icons

Post by kltpzyxmrm »

Windows 10 pro, creators update, Firefox 54.0b10 & 53.0.3x64

I use mozilla archive format which allows me to save .mht files from Firefox.

The problem is the files have a "blank" where the Firefox icon should be.

I remember having this problem in the past with XP. If I'm not mistaken I used "Folder Options > File Types" to associate .mht files with the Firefox icon.

In Windows 10, the "File Types" feature has been eliminated.

Firefox is the default browser.

I tried a third party tool, FileTypesMan, which works similarly in most cases, and pointed .mht to the firefox executable for the default icon.

I went to "Associate a file type or protocol with a specific program", and it shows that .mht is associated with firefox, but there are quite a few file types there with "blank" icons, including .mht.but doesnt fix this problem.

thanks

You should check for the proper Registry keys: HKCU\Software\Classes\.mht key should have default value of "FirefoxMHTML". Then below that, HKCU\Software\Classes\FirefoxMHTML\DefaultIcon should
have default value of ""C:\Program Files\Mozilla Firefox\firefox.exe", 1" (if your FF install location is different, adjust accordingly).
