Firefox has a bug in version 3.6.11, 3.6.12, 3.6.13+ This bug is a problem in SQLite and causes bookmarks to become unbearably slow when searching on some systems. The estimated fix will be released with the public version of Firefox 4 however I urge you to politely ask them to create a hotfix update before it's release. at support.mozilla.com A link to the correct report is in the related links section below.
As a current workaround you can try these things:
go to bookmarks, go to organize bookmarks, then just delete them
You can import bookmarks stored in HTML format from a file, using the Import feature of the Bookmarks Manager: * Firefox 2 and earlier: "Bookmarks -> Organize (or Manage) Bookmarks -> File -> Import -> From File" * Firefox 3: "Bookmarks -> Organize Bookmarks -> Import and Backup -> Import HTML... -> from an HTML File"
No... you can't retrieve bookmarks
Firefox bookmarks can be easily imported in Chrome browsers. Chrome has an option of import browser bookmarks for this.
Go to Bookmarks > Organize Bookmarks... > Import and Backup > Export HTML
If you uninstall Firefox and do not check the box that reads "Remove my Firefox personal data" then your bookmarks (and other Firefox settings) will be preserved because they are kept in your Profile Folder which is saved in a different location than your Firefox installation folder is so if you reinstall Firefox or update it, your previous bookmarks (and other Firefox settings) will all be intact.If you plan on reformatting your computer you must backup your Firefox bookmarks and settings to an external location such as to a USB drive, a CD, external hard drive, or use an online bookmarking service.Most online bookmarking services allow you to import your Firefox bookmarks and there some that offer automatic bookmarks synchronization between their service and your Firefox.
Even when uninstalled or deleted, Mozilla Firefox will leave your bookmarks behind. They will still be there if you reinstall it.
Detects Duplicate Bookmarks when bookmarks are added and specify where is the previous URL. You can also search and delete duplicates URL already in your Bookmarks. Firefox 3.5 support is available from http://bookmarkdd.mozdev.org in version 1.0.0. https://addons.mozilla.org/en-US/firefox/addon/1553
There's no such thing as Favorites for Firefox, instead it is called Bookmarks
bookmarks
Click the Bookmarks menu, then select "Organize Bookmarks...". Or simply press Ctrl+Shift+B
To keep your favorites in Firefox, you can use the Bookmarks feature. Simply click on the star icon in the address bar when you're on a webpage you want to save, and select a folder to store it in. You can also organize your bookmarks into folders by going to the Bookmarks Library (Ctrl + Shift + B) and dragging bookmarks into desired folders. Additionally, consider syncing your bookmarks with a Firefox account to access them across multiple devices.
