Hello StevenBeary, the 34.0.5 release it is for all users who download a fresh version of Firefox, or download it for the first time. This release will NOT be found via Firefox's update. Firefox 34, it is the latest release via update. You are OK.

see Tyler Downer's explanation.

thank you

Note that the only difference between Firefox 34.0 and 34.0.5 is that the latter sets the default search engine to Yahoo! if you are in the US timezone and haven't changed the default from Google.

See info above. I have re-run the update process at least 10 times on both machines running Windows 7 Pro (most recently this morning), and each time both machines running Windows 7 Pro (one is 64-bit, one is 32-bit) say that Firefox v34.0 is "up to date". I checked Mozilla.org, which states that Firefox v34.0.5 was released in mid-December, but it didn't say anything about whether that update was only for certain OSs. I have also run multiple anti-virus scans from different providers on both machines running Windows 7 Pro, and all scans indicate no issues. Please advise is there are different versions of Firefox for Windows 7 Home/Pro, or if I am having an issue. If I am having an issue, please advise how I can correct it.

One poster suggests that Firefox v34.0.5 cannot be accessed via the standard "update" method (click on "three bar", then "?", then "About Firefox") but rather, only via a "new" or "first-time" download, but that is how I got it on the machine with Windows 7 Home. It updated from v34.0 to v34.0.5. Perhaps the poster was mistaken?

We changed how updates were deployed for a test, which is why you likely had the 34.0.5 on one computer and 34.0.0 on another. The only difference between them is that 34.0.5 sets yahoo as the default search. You don't need to worry about having the different versions (which both were released at the same time BTW)
