Latest install 43.0.4 on Mac 10.6.8 is working, but the icon will not install on the dock; replaced by a question mark.

No round Firefox icon appears anywhere after download, so I can't drag it to the dock. That space on the dock is a persistent question-mark. The FF icon was still on the dock as recently as last week with an older version of FF.

Hello forestseeds, try one more time, but to download firefox full dmg package :

1. Download a copy of the latest firefox from (full dmg package)

2. Trash the current Firefox application to do a clean install.

3. Install the version that you have downloaded.

Do not select to remove your personal data, your profile data is stored elsewhere in the Firefox Profile Folder, so you won't lose your bookmarks or other personal data.

Very puzzling. I did the complete new install in the sequence you suggested, and removed the previous version, and FF is working--but still doesn't appear on the dock (instead there is the question mark).

Also, when I did the install, it got filed on the Mac hard drive separate from Applications. According to Spotlight, they are in Documents--but the Documents folder is empty. So it seems that the full dmg package is still not installed somehow.

Further ideas?

This may provide another clue: in the current, apparently incomplete download, any short video I try to play, crashes Firefox!
