The V21 "offer" pops up, and when I click on it, I get the downloading symbol but it never completes. I have had several tries, and left in on for hours. I know that when I had a Windows PC I sometimes had to switch off the Firewall or even the anti-virus for some downloads, but I don't know whether that would even be possible with an iMac, and if it is, don't know where to start. V20 runs fine, with one exception - the icon for Firefox disappears from my dock every few days, and is replaced by a question mark. Clicking on that brings up the icon, which I can drag back to the dock ; but this is only a minor irritation.

Hello Dorsetman, if you have problem with update firefox the better way is to download and install the new version.

1. Download a copy of the latest firefox from http://www.mozilla.org/en-US/firefox/all.html

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.
