  • I need access to older versions of FireFox and checksums for these files.

    For each version listed below I need the installation download file and md5/shaXXX checksum from Mozilla for each download.
    WindowsOS: Firefox v3.5, v3.6
    Solaris 10 x86: Firefox v3.5, v3.6
    Solaris sparc: Firefox v3.6.17
    filename: firefox-3.6.17.en-US.solaris-10-fcs-sparc-pkg

    Everything you want for current Firefox 3.6 is on the FTP server here:
    * ftp://ftp.mozilla.org/pub/mozilla.org/firefox/releases/latest-3.6/
    There's two big files for all MD5 and SHA1 sums of everything. Solaris is under the contrib dir.
    The current version of Firefox 3.x is 3.6.23. Firefox 3.5 is no longer supported and Firefox 3.6 is considered a direct update (aka minor update) to Firefox 3.5; when Firefox 3.5 users check for updates they go directly to 3.6 for security and stability fixes.
    If you really need an old version for testing purposes, you can get any version of Firefox that ever existed off of the FTP server:

  • Since installing Firefox 4.0 I cannot scan on my HP Photosmart C4480 printer/scanner/copier. Do I need to use older version of Firefox?

    Installed Firefox 4.0 after using Internet Explorer for many years. Everything works fine, except cannot scan on HP Photosmart C4480 printer/scanner/copier. Can copy and use printer, just cannot scan pictures in any more. HP help center will not open.

    Firefox 4 requires at least OS X 10.5 and an Intel Mac.

    For Mac OS X 10.4.11 or Mac OS X 10.5.8 you can look at:

  • Why do websites think I am running an older version of Firefox when I have version 4 installed (Mac OS 10.6.7)?

    Certain websites like my banking website and another one that tests for system compatibility seem to think that I am running Firefox 2 when I am actually running 4.0.1. What would cause this to happen and how can I fix it? I am on a MacBook Pro running Snow Leopard (v 10.6.7).

  • Do I need to remove the older version of firefox before installing a new version? If so, then how much do I remove, and how?

    I have an older version of Firefox and adobe on a Sony VAIO. I keep getting pop-ups telling me to upgrade, and also frequent failures when I try to use the browser. I try to upgrade. I go thru the download step, then try the run step and get a message "not allowed". I have checked and I have admin privileges, and I've turned off the firewall security software thinking that it's blocking the install, but nothing works. Does anyone know if the older software is causing this and does it need to be removed before the latest version can go on. Also, if this problem is resolved am I going to have the same problem with Adobe?

    What Firefox version is currently installed on the computer?
    You can find the full version of the current current Firefox release (37.0.2) in all languages and all operating systems here:
    *https://www.mozilla.org/en-US/firefox/all/
    If you have a very old Firefox version then you could consider to uninstall that version to clean up existing registry keys (especial the uninstall key).
    Make sure NOT to remove "personal data" when you uninstall Firefox, because that will remove all profile folders and you lose personal data like bookmarks and passwords including data in profiles created by other Firefox versions.
    Check the Firefox program folder and remove the Firefox program folder if there are still files left in it.
    *(32 bit Windows) "C:\Program Files\Mozilla Firefox\"
    *(64 bit Windows) "C:\Program Files (x86)\Mozilla Firefox\"
    It is important to delete the Firefox program folder to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.
    *http://kb.mozillazine.org/Uninstalling_Firefox
    Your bookmarks and other personal data are stored in the Firefox profile folder and won't be affected by an uninstall and (re)install, but make sure NOT to remove personal data when you uninstall Firefox as that will remove all Firefox profile folders and you lose your personal data.

  • I need to apply for a student loan and I am told that the version of firfox is not supported It recommend I download an older version: Mozilla Firefox 3.5.x and 3.6.x How do I do this?

    I'm told to download an older version of firefox that supports the application for federal student loan. They want me to download: Windows 7 - Mozilla Firefox 3.5.x and 3.6.x

    The fafsa.gov site does not currently support Firefox newer than version 3.6.x. That is their choice.
    You can install Firefox Portable version to use only on that site and use your installed current Firefox version for everything else. Firefox Portable is not produced by Mozilla (but is based on Firefox released versions) and is not supported on this site -- has its own support forum (see below). Firefox Portable installs in a separate folder on your hard drive so that it does not interfere with your currently installed Firefox version settings or personal information (bookmarks, passwords, etc.). You can also install Firefox Portable on a USB/thumb/pin/jump drive.

  • What steps are needed to download an older version of Firefox for testing an Oracle certified version?

    I want to download an older version of Firefox for testing Oracle certified versions (for PeopleSoft PeopleTools). I found the directory of older versions but need instructions for the steps needed to download the desired version, which is version 17. Thank you for your help.

    Firefox 3.5 is an antique version that is chock-full of security vulnerabilities.<br>
    Firefox 3.6 also contains security vulnerabilities; it stopped being supported on April 24.
    * [https://www.mozilla.org/security/known-vulnerabilities/ www.mozilla.org/security/known-vulnerabilities/]
    If you can't run the latest version because your system doesn't meet the requirements, it's highly recommended that you use another browser that is secure. TenFourFox is a third-party build of Firefox that is kept up-to-date and runs on Mac OS X 10.4 and PowerPC Macs (as a side note, I've never seen the site go down; whatever problems James noticed 9 months ago must've been a fluke).
    * [http://www.floodgap.com/software/tenfourfox/ www.floodgap.com/software/tenfourfox/]
    If your system can run the latest version, but you want to downgrade because you've experienced problems, please start a new thread and someone will try to help you.
    If you understand the security risks but want to downgrade anyway,
    * Firefox 3.6: [http://www.mozilla.com/firefox/all-older.html www.mozilla.com/firefox/all-older.html]

  • I downloaded  reader 11.3, do i need to uninstall older versions ?

    i downloaded reader 11.3 ,do i need to uninstall older versions ?

    If you have Reader 10.x or 11.x installed, there is no need to uninstall.  Older, or much older versions should be uninstalled before installing a much newer version.

  • How can I get back to an older version of Firefox? I have an add-on that is not compatible with version 5.0 but I need it !

    I have installed Firefox 5.0 but this version does not work with some of my add-ons.
    There are no new versions of the add-ons yet.
    I want to uninstall Firefox 5.0 and install an older version of Firefox.
    How do I do that?

    The latest versions of Firefox require at least Mac OS X 10.5 and an Intel processor. You can revert to Firefox 3.6.xx for Mac 10.4 by downloading the installer from http://www.mozilla.org/en-US/firefox/all-older.html

  • I need to reinstall the older version of Firefox since 4 doesn't work with my laptop - where is it?

    I updated to 4 but now it won't open. The install replaced my older version of Firefox. I can't figure out how to uninstall 4; and will that make my older version available again? If not, is it available for download on the Mozilla website?

    There is a third party version of Firefox 4 that runs on OS X 10.4/10.5 and PPC Macs, for details see http://www.floodgap.com/software/tenfourfox
    If you prefer, you can get the latest version of Firefox 3.6 from http://www.mozilla.com/en-US/firefox/all-older.html
