How to return to Firefox 3.6?

Firefox 4 is not a supported browser for the University I attend. It does not work for online courses, and I need to go back to Firefox 3.6. Help, please! Thank you.

Downgrade to Firefox 3.6 first of all uninstall Firefox 4, but do not select the option 'remove my Firefox personal data '. If you select this option, it will delete your bookmarks, passwords and other user data.

Then you can install the latest version of Firefox 3.6 available to http://www.mozilla.com/en-US/firefox/all-older.html - it will automatically use your favorite courses, passwords etc.

I recommend, to avoid possible problems with decommissioning, accessing your profile folder and delete the following files if they exist - extensions.cache, extensions.rdf, extensions.ini, extensions.sqlite and localstore.rdf. Delete these files will force Firefox to rebuild the list of installed extensions, check their compatibility and cancel the toolbar customizations.

For more information on how to find your profile folder, see https://support.mozilla.com/kb/Profiles

  • How to return to 24 of Firefox

    Upgrade to FireFox 25 on 05/11/13 and could get some information on a site immediately not much confidence I took for granted with FireFox 24. I use this feature A MUCH (MUCH!) Every day. But now I can't. The site allows you to display certain information automatically but seems not to do. By default FireFox reset or what you call does not solve the problem. How to return to 24 of FireFox to see if that solves the problem? The forum thing doesn't have the answer I can say. Your website doesn't even have it.

    Hi WarrenSmalley, to replace your current bookmarks + historical database with the former, you need to open both files at the same time, the release of Firefox, then copy the old file (I suggest copying rather than moving so that you can keep a non-corrupt copy).

    To open your current profile folder, either:

    • use the help > troubleshooting information > "view file" button.
    • type or paste everything: in the address bar and press Enter > "view file" button.

    You already know the location of your old profile folder (Desktop-old data from Firefox).

    After the release of Firefox, allow a few moments for the files to be updated before making the change.

  • How od I return 22 Firefox

    If I had known you were going to change my UI (skin) I wouldn't have updated! Now that the toolbar of the URL (something that I rarely use) is attached to the tabs, I lost a quarter of an inch from my view. I keep this default toolbar. I wish you had warned me that your toolbars would crowd on my tab display area. Seems like a small problem, but not for me. I wish that you offered to let me and all of us the opportunity to keep the same interface and just download security fixes. Its form current Firefox 22 was very good and I knew where everything was. When I disabled the menu at 22 bar, I had a full half inch of display area. Now its less than an eighth. So please tell me how to get back 22 and keep my information intact. In the future please offers the skins separately from security updates for people like me who like the interface that they can keep them. Thanks David

    Is this possible?

    Creating a profile will return all of your default settings of Extension/add-ons, you will need to re - install the Extensions/additional custom modules in the new profile

    Most of the settings that you have probably set different values are in about: config, then filter = network.http (I watch 24 elements in Firefox 6, all with the 'status' = default)

    • Those that are displayed in the lower panel in fat and as a user set are items that have been modified by you and/or an extension/add-on.
    • You can right-click on these elements, in your case those typically shown as "whole" types and choose "Reset".
    • Those who re - appear after restart of Firefox are possibly be changed/added by an Extension; There were / are many extensions to change these settings
    • After "Reset", not with an empty value (there should be none in network.http unless you added), will be deleted when you restart Firefox. those are elements that are not the default set of preferences hidden in your version.
    • Make a list of what you change hidden preferences (topic: config) so that you can reverse these changes later if needed.
    • List of preferences network.http: _ http://kb.mozillazine.org/Firefox: _FAQs_:_About:config_Entries #Network.
      • The list is not entirely current or complete, but is the best we have at this moment
      • Do not add new products to your preferences, unless you know what you're doing
      • Do not delete all the elements of your preferences, unless you know what you're doing
