i add bookmark but when i logedout all my book mark get lost, there is any limit ie number of bookmarks can be added

Hi,
In firefox go to Edit->Preferences and select the Privacy tab, then look at the last two options checkboxes with a legend like "Always delete my private data..." and uncheck it.
Hope this helps, let me know.

I don't think "Always delete my private data..." deletes bookmarks. Note that through "Organise Bookmarks" you can Export all your bookmarks to a local file. I'm not sure if you can find a work-around using that. I don't think there's an upper limit on the number of bookmarks but there might be

Good uck and regards from
Tom :)

Hai Tom,

                I am sorry to said that it did not help me, i have many friends using the firefox but i am the only one facing this problem. There is any problem with the configuration. I add 11 bookmarks when add the 12th it will show, but when i closed the firefox and when reopen it will not show(the last one i add) this my main problem.

 Please help, I am waiting for your reply

Hi philipalex,
I agree with Tom's advise, my mistake, my mind change the meanings between "navigation history" and "bookmark". I confirm there is no limit on bookmarks, you can have all you want (certainly I have more than fifty).
Maybe your bookmark file is corrupt, try the following:

Starting in Firefox 3, bookmarks and browsing history are stored in the "places.sqlite" file in the Firefox profile folder. If there is a problem with this file, bookmark changes can be lost when you next restart Firefox. If restoring a bookmark backup from within Firefox 3 does not work or doesn't resolve the issue, you can rebuild the Places database as follows (however, this will remove your browsing history of recently visited pages): [4] [5]

   1. (Optional) Export your bookmarks to a file named "bookmarks.html" (or use a previously saved bookmarks.html file) and place it in the Firefox profile folder. If a "bookmarks.html" file already exists, allow the exported (or previously saved) file to replace it.
          * To export your Firefox 3 bookmarks, go to "Bookmarks -> Organize Bookmarks -> Import and Backup -> Export HTML".
   2. Close Firefox completely (or restart the computer).
   3. Open the Firefox profile folder and delete (or rename) the "places.sqlite" file and, if it exists, "places.sqlite-journal".
   4. (Optional) To force Firefox to automatically restore your bookmarks from the profile folder "bookmarks.html" file, instead of from a JSON backup, open the bookmarkbackups folder and remove all bookmarks-(date).json files to another location. (This may be necessary, in some cases, if there is also a problem with the JSON bookmark backup files.)
   5. It is probably also a good idea to delete the localstore.rdf file, to remove the references to the old Places file (you will need to add back any toolbar customizations).
   6. Restart Firefox.

Firefox will create a new "places.sqlite" file and automatically import the most recent JSON bookmark backup file. If no JSON backup is found, Firefox will automatically import your bookmarks from the profile folder "bookmarks.html" file, if it exists.

Note: You may also need to use about:config to reset all of the browser.places preferences to the default settings (see above).

Hope this helps, let me know.

Hello Ariel Cabral,

                        Thank you very much for your reply. I am going to do the steps you mention here. I hope this will help me to solve the problem.

===================
 1. (Optional) Export your bookmarks to a file named "bookmarks.html" (or use a previously saved bookmarks.html file) and place it in the Firefox profile folder. If a "bookmarks.html" file already exists, allow the exported (or previously saved) file to replace it.
          * To export your Firefox 3 bookmarks, go to "Bookmarks -> Organize Bookmarks -> Import and Backup -> Export HTML".
   2. Close Firefox completely (or restart the computer).
   3. Open the Firefox profile folder and delete (or rename) the "places.sqlite" file and, if it exists, "places.sqlite-journal".
   4.

Hi

Many apologies for the spam from Marianne. I suspect she has accessed her email account form a Windows machine and got it infected somehow, either that or it's an accident i guess.

Please do NOT follow the link given, although it might be fairly harmless.
