Hello people,

I have a problem. At the moment I am running a Firefox version 143 on Linux with different windows. At the top left you can then select which windows you want to use. Only now it has disappeared. You get a home page. I have tried several solutions. Anyway, how do you get the rest back? Thanks.

How I did this :

If you’ve reinstalled **Firefox** and now have a folder called **“Old Firefox Data”** on your desktop — that’s actually **a backup** of your old Firefox profile. It contains your bookmarks, passwords, history, extensions, etc.

Here’s how you can **restore** that old data into your new Firefox installation:

---

      1. 🧭 Step-by-Step: Restore “Old Firefox Data”

1. **Close Firefox completely.**

2. **Find the Old Data folder:**

  * On your Desktop, look for a folder named something like
    `Old Firefox Data`.
  * Inside, you’ll see a subfolder with a random name, e.g.
    `abcd1234.default-release`.

3. **Open your current Firefox profile folder:**

  * Open Firefox.
  * Type in the address bar:
    ```
    about:support
    ```
  * Press **Enter**.
  * Under **Application Basics**, find the line **Profile Folder** and click **Open Folder**.

4. **Replace the new profile with the old one:**

  * Close Firefox again.
  * In the opened folder, go **one level up** (so you see multiple profile folders).
  * Delete or rename your current profile folder (e.g. rename `xyz.default-release` → `xyz.default-release.backup`).
  * Copy the old profile folder (from “Old Firefox Data”) into this location.

5. **Launch Firefox.**

  * Firefox should now start with your old bookmarks, extensions, passwords, and history restored.

      1. 💡 Optional (if it doesn’t work)

If Firefox opens but doesn’t show your old data:

  • Open `about:profiles` in Firefox.
  • Click **Create a New Profile** → choose the folder you copied from “Old Firefox Data”.
  • Set it as **default**, then restart Firefox.

This case can be closed.
