I wish not to remove the old version because I have to get the extensions again + do the settings again.
What I did first is I checked for updates online via Firefox Options>Advanced>Software Updates>Firefox. It didn't detect that I need new version 1.0.1 or the the security update so I thought uninstalling old version is "the way to go" because if we can install over the top of v1.0, the built-in updater should be able to detect it.
Also, they noted in their Releases page:
Prior to installing Firefox 1.0.1, please ensure that the directory you've chosen to install into is clean and doesn't contain any previous Firefox installations
On my other box (a test box), I installed over the top to check if it will run normally, if the extensions is 1.0.1 compatible and if there's any other issue. All is well except what you've seen - 2 entry of Mozilla Firefox - 1.0 and 1.0.1.
I will proceed now to Secunia test pages and other sites test pages to check if the:
Security hole fixes are fixed <g>
22183 - Display hostname in title bar when address bar is hidden, to reduce the impact of the fact that web sites are allowed to spoof address bars.
260560 - Security and download dialogs can be spoofed by covering them partially using popup windows.
262887 - Secunia background tab security issues (SA12712).
273699 - 2 Frame Injection Vulnerabilities (popup blocking race condition & onunload event mis-firing).
275417 - Download dialog source spoofing (SA13599).
279945 - Image drag and drop allows to create executable files.
280603 - "New Updates Avail" popup in bottom right-hand corner pops up endlessly / excessive hits on update service.
280664 - Using Flash and the -moz-opacity filter you can get access to about:config and make the user silently change values.
282270 - Display IDN URLs as punycode by default (controlled by a hidden pref).
Thanks for the link to the discussion JR.
I downloaded the new version of Firefox 1.0.1 and then installed over the top of version 1.0. Noticed in Add/Remove that it showed both 1.0.1 and 1.0, so I deleted version 1.0. Well, the Firefox Icons disappeared including the one I had in the Task Bar. Doing a search, I still find stuff from the old 1.0 back to when I installed Firefox last year. I figured I made a mistake in deleting the 1.0, so for the first time in about a year I used my commercial GoBack3 going back to before the installation and regaining the 1.0. Still have the 1.0.1 downloaded but waiting to reinstall. Now, I thinking, something is just not right, after searching the CNet forums, finding no comments I went to the Mozilla forums and found about a dozen with the same sort of thing as my experience:
Some seem to suggest waiting about 10 more days to install. Another says that the 1.0.1 should be a update patch to install over the top and not delete the old. Another says he had no problems installing over the top (I didn't either).
Think I'll wait awhile to see how this all comes out before installing again. I'm not comfortable with two versions of Firefox in Add/Remove and the two versions in C:/Programs.
Only installed this on my WinXP (off the net & clearing programs running), after checking anti-virus, AdAware, SpyBot, and MS AntiSpyware, in case someone is wondering.;-)
