Hi,

I'm a recent convert to Firefox.

Today, it crashed and I was given the option of Safe Mode or Refresh. I chose Refresh probably thinking that it would not change anything.

When I logged back on, I got the vanilla Mozilla setup. I keep getting asked to save passwords on each site, all of my history has been lost and all of my add-ons have been lost. I'm in the process of restoring as many a I can remember.

Was this the result of Refresh which is really Initialization ?

Is there anyway to recover my previous settings ?

Thanks,

jkur416

Chosen solution

Refresh will reset Firefox to its factory settings and setup. Safe mode will temporarily reset Firefox to its factory settings and setup for diagnostics.

When you reset Firefox then a new profile is created and some personal data (bookmarks, history, cookies, passwords, form data) is automatically imported and the current profile folder will be moved to the desktop to an "Old Firefox Data" folder. Installed extensions and other customizations (toolbars, preferences) that you have made are lost and need to be redone.

Wesley.

I was afraid that it was due to the Refresh. I'll look into backing up profiles and see if I can still recover from an old profile.

Thanks,

If your old profile was behaving badly, this might not be helpful, but I'll mention it as an option... a procedure to revert to your pre-Refresh data.

Check inside "Old Firefox Data" folder that Refresh adds to your desktop for a folder with a semi-randomized name. If there's only one, that probably has your old settings and add-ons. If there's more than one, you'll want to work with the one that was updated most recently.

Once you have identified the profile folder you want to restore, here is my suggested "old profile resurrection procedure":

Overview

These are the steps described in more detail below:

  1. Create a new Firefox profile
  2. Remove everything from that new profile folder
  3. Copy in everything from the old profile folder

Create a new Firefox profile (Windows)

Exit Firefox and start up in the Profile Manager by pasting the following into the Start menu search box, or the Start > Run dialog, and pressing Enter:

firefox.exe -P

Note: Any time you want to switch profiles, exit Firefox and return to this dialog.

Click the Create Profile button, assign a name like OldSettings, and skip the option to change the folder location. Then select that new profile in the dialog and start Firefox.

Open the New Profile folder in Windows Explorer

Firefox in the new profile should look like a factory fresh installation. Open the Troubleshooting Information page using either:

  • "3-bar" menu button > "?" button > Troubleshooting Information
  • Help menu > Troubleshooting Information
  • type or paste about:support in the address bar and press Enter

In the first table, click the "Show Folder" button. Firefox will launch your brand new profile folder in Windows Explorer.

Leaving that folder open, switch back to Firefox, and Exit using either:

  • "3-bar" menu button > "power" button
  • (menu bar) File > Exit

When Firefox closes, the profile folder should be front and center, or you can activate it using the Task bar.

Copy Old Data in Place of New

In that new profile folder you just popped open -- NOT the one on your desktop -- select all the contents (you can use Ctrl+a) and delete (you can press the Delete key on the keyboard).

Leaving that window open, open or switch over to your Old Firefox Data folder. Drill down into your old profile folder. At this level you should see a folder named bookmarkbackups among other things.

Select everything (Ctrl+a) and Copy (either right-click > Copy or Ctrl+c).

Switch to the empty new profile folder in other window and Paste (either right-click > Paste or Ctrl+v). This may take a minute since some of the files are large.

Start Firefox

Firefox should start up in that "new" profile with the resurrected old profile data. Success?

You can use the profile manager to switch between profiles as needed/desired to research settings and figure out what you want to copy over. Please don't use the Profile Manager's "delete profile" button without a backup -- it's just too easy to delete the wrong one by mistake.

jscher2000,

Wow. Thanks for the detailed information.

I've restored many of my settings, but I'll see if I can can use your methodology.

Thanks again,
