Firefox 3 offers different backup/restore methods of your bookmarks grouped in the Library. You can export your favorites to HTML format or save them as a JSON file that allows Firefox to list them chronologically. Don't lose your bookmarks, do regular backup by learning how!
Start by opening Firefox 3 and then the Library module from the menu Bookmarks then Organise the bookmarks...
You can also press the keys Ctrl + Shift + B.

Save your bookmarks
We will now detail the 2 backup methods proposed by the browser: HTML export and JSON backup.
1era method — HTML Export
Once opened, click on the button Import and safeguard.

Here, choose Export to HTML format... then select the location where you want to perform the backup.
2e method — JSON Backup
This second method has the advantage of classifying backups chronologically in order to restore them at a specific date — in the same way as a Windows restore point.
To do this, click again on the menu Import and safeguard then on Save...

Choose the backup location using the dialog box and click the button Save.
Now you know how to quickly and easily make backups of your Internet favorites. The second step is to learn how to restore them.
Restoration of your bookmarks
1era method — HTML Importation
You can import any type of HTML file in other words it is not necessary to have an export of this type using Firefox. This system therefore offers greater flexibility!
To proceed with the restoration, click on the button Import and safeguard then on Import in HTML format...
An assistant runs offering you to import your bookmarks from:
- Microsoft Internet Explorer;
- From an HTML file;
So opt for the second proposal and click on Next.

Then search for the relevant file and click on Open.
Your bookmarks are now present in the Library.
2e method — Restoration JSON
This process assumes that you have previously made a backup using the Firefox 3 backup function (see paragraph above).
To restore your favorites, click Import and safeguard then unfold the menu Restore.
Simply click on the date of your choice to retrieve all your bookmarks on the date in question. Note that these are displayed in this form YYYY — MM — DD (Y for Year, M for Month and D for Day).

You also have the option to open a file that would not appear in this list by clicking on Choose a file...
Now that you know more about saving and restoring your bookmarks in Firefox 3, take the lead and don't wait for a PC crash! Losing your favorites is really very unpleasant...

Good morning,
I did what you said, but in my personal bar, I still see the old icons of the old favorites: nothing seems to have changed. How to do stp?
Fanch : what method did you use? Have you searched the various folders in your bookmark library to see if they had not reappeared in a specific folder?
An artículo de gran utilidad cuando se instala firefox 3 in a nuevo ordenador y se quieren importar los marcadores. In la página de firefox dicen que se copie toda la carpeta del programa pero eso no es práctico si que quiere empezar con él desdes 0 excepto el caso de los marcadores. Muchas gracias.

Have you tried the shortcut Ctrl + Shift + B to open the Library?
You must have access to this module, otherwise you reinstall Firefox.
Clear and precise tutorial. Bravo +++
