Thread: Installing updates

  1. Installing updates

    I'm seeing a lot of conflicting info about how to do an update. I don't
    know if the safest way (safest for my definition is maintaining my
    existing extensions, my bookmarks, preferences, and my stability . . .
    btw, I DO realize that stability cannot be guaranteed, but at least I'd
    like to keep the add ons).

    On the "more info" link in the update window (release notes for 3.0.3),
    for example it says on the one hand:

    "Please note that installing Firefox 3 will overwrite your existing
    installation of Firefox. You won’t lose any of your bookmarks or
    browsing history, but some of your extensions and other add-ons might
    not work until updates for them are made available."

    This would lead me to believe that my extensions are at risk and I might
    have to go through the tedious process of reinstalling them all again if
    I let the update overwrite the existing installation of 3.0.1.

    And then it says:

    "Removing Firefox 3 won’t remove your bookmarks, web browsing history,
    extensions or other add-ons. This data is stored in your profile folder.
    Any version of Firefox that you install after removing Firefox 3 will
    continue to use the data from this profile folder."

    Which in addition to seeming to be in conflict with the first statement,
    leads me to believe that to be safe I should uninstall my version 3.0.1
    first and then install version 3.0.3 (the update) and back up my
    preferences file (which I should probably do which ever method I choose).

    The KB articles on this topic are confusing also.

    Or am I reading these things wrong??

    My preferences file is a javascipt file . . . prefs.js . . . isn't it??
    (I know where the prefs.js file is and I haven't made a user.js file,
    but I wouldn't think I would need a user.js file for this operation . .
    .. or would I?)

    So, since my goal is to preserve the extensions I have already
    installed, should I FIRST uninstall 3.0.1, or will that extinguish
    forever my existing extensions loading in the update?

    When you install a new version, this is what happens, in simplest terms
    Obviously a new exe file's used.
    On first run it scans all extensions to see their max version.
    If it's lower than firefox's version, firefox will let you know, then
    ask if you want to check for updated versions
    If you say yes it'll try and find them.
    If a compatible update is found, it's downloaded and installed.
    If no update is there, the extension will be *left* installed, but
    disabled.

    There are workarounds to get files to work with different versions. If
    you're fairly technical, editing the install.rdf file's maxversion entry
    to 4.* will do it, you can extract it from the extension file with
    winrar and then reinsert it. If you want to do this, ask or research
    first. Further, there may be another extension that suits you better and
    is compatible. Ask in here again if you find any you really need.

    And sorry for not answering this part :
    The extension data is stored in your profile folder, under Vista that is

    C:\Users\!!\AppData\Roaming\Mozilla\Firefox\Profil es\??\extensions

    !! is the windows user name.
    ?? could be one of several folders. Check for the one with the most
    recently modified date.

    My understanding is that these folders are left as-is on uninstall. I'm
    pretty sure that's the case from personal experience too. However your
    safest bet is to let Firefox upgrade itself after backing up your data.

    On that note, I *can* tell you from personal experience you can
    copy-paste all the data in the appdata folders to different PCs and
    windows users. Pasting them onto another user or PC puts all 'your data'
    on that PC, including bookmarks, extensions, the works. So you may be
    best served by backing up the mozilla folders in there (Vista has
    'Local' and 'LocalLow' at the same level as 'Roaming' in the above path)
    first. Then if things go badly you can copy your old settings back.

    Well . . . I took a chance and just downloaded the update and let it
    overwrite.

    It did it all very nicely and scanned for compatibility with the add ons
    (as part of the install process . . . as you said) and everything was fine.

    I assume if it had found one that needed updating to be compatible, it
    either would have told me which one it was or gone ahead and made the
    update to the add on.

    In any case, all my add ons were intact, and so also was EVERYTHING else.

    The update was trivial. It really went smooth.

    I suspect that was because the "leap" from 3.0.1 to 3.0.3 was small indeed.

    So now I'm wondering if I will have to do the complete uninstall dance
    when they come out with 4.0? Or will an overwrite just tell me which add
    ons need updating and disable them 'till they're updated to be
    compatible with 4?

    Sorry for not mentioning that you said this in my previous post. My
    statement that it would probably do all these things was really yours.

    No worries. The main thing's it went OK.
    As for V4, I doubt it, I haven't had to when updating from 1.x to 2.0 or
    2.x to 3.0 so providing the pattern follows, all good.

    On the MozillaZine forum, one of the MOD's said that version 4 would be
    a loooooonnnngggg time coming out.
