I've been experiencing problems with the newest update of Firefox since it came out. My toolbars don't right. It crashed on me several times, and now I've discovered that after the crash, it went back to default mode and wiped out all my usernames/passwords.

I tried a system restore on my Windows Ultimate 7, but that didn't do anything. And by toolbars, I mean the Yahoo! Toolbar for firefox.

I have version 43.0.4 as of today.

Look on your desktop. Do you see a folder called; Old Firefox?

FredMcD, this restore did nothing for me. Nothing was backed up and restored. Any other suggestions?

I did not say anything about a restore. Re-read my last post.

FredMcD, I'm so confused at what it is I'm looking at. What am I supposed to do?

Your flash and Firefox are both out of date. Follow the instructions above to update them.

FredMcD, firefox had the correct version. I did everything else as you requested. By the way, I encountered several more crashes before completing everything you said.

Not just Firefox, but Opera as well. And I still haven't recovered my passwords.

You first need to verify if you still use the old default profile or that Firefox has created a new profile.

How long go the bookmark backups go back if you check that in the Bookmarks Manager (Library)?

  • Bookmarks > Show All Bookmarks > Import & Backup > Restore

If there are only recent backups then it looks that a new profile got created.

You can check in Windows Explorer if there is a previous version of the logins.json file available.

FredMcD, yes, I tried that already. Nothing was restored. I have no clue why everything got wiped out.

Did you check if there are multiple profiles?

You can use this button to go to the current Firefox profile folder:

  • Help > Troubleshooting Information > Profile Directory: Show Folder (Linux: Open Directory; Mac: Show in Finder)

Go up one level to the Mozilla\Firefox\Profiles folder.

  • C:\Users\<user>\AppData\Roaming\Mozilla\Firefox\Profiles

Open this folder. What are the dates of the folders inside?

FredMC, one is 2014 and the other is 2016. Apologies for the late replies. College is kicking my ass.

Open the 2016 folder and use these files to restore your profile.

Type about:support in the address bar and press enter.

Under the page logo on the left side you will see Application Basics. Under this find Profile Folder. To it’s right press the button Show Folder. This will open your file browser to the current Firefox profile. Now Close Firefox.

These can't get your data back, but will help in the future.

These add-ons can be a great help by backing up and restoring Firefox

You can check in Windows Explorer if there is a previous version of the file available.
