-> click Firefox button and click Exit

Start Firefox in Safe Mode by Holding down the Option key while starting your Mozilla application.

As an alternate method, go to Utilities (in the Applications folder) and open Terminal, then run:

    /Applications/Firefox.app/Contents/MacOS/firefox-bin -safe-mode 

-> Firefox Safe Mode window will appear. DON'T SELECT ANY OPTIONS, just click Continue in Safe Mode

Firefox will open up with just basic Firefox. Check and tell if its working while you are in Safe Mode.

A possible cause is a problem with the file places.sqlite that stores the bookmarks and the history.

Hello, thank you for your reply and help. Finally I have created a new subfolder for the booksmarks:

1. I copied all of the bookmarks - did not help same problem 2. I copied them one by one and check after each time if the problem persists. 3. To my surprise I found one specific website that causes this problem. If Iput it in the bookmark folder, the folder would not open. The moment I take it out everything works.

Any ideas why that happens?

which website was it ??

Sounds that you have a corrupted bookmark.

See my above post.

Hello,

this is the website: http://www.traumflieger.de/

But I found something interesting. Originally I had a bookmark folder called "Canon" where I had this problem. I created a folder called Canon 1, copied over all the bookmarks and the problem persisted because of that website.

Out of interest I put this website into another existing bookmark folder that I had and to my surprise there was no problem. Maybe this website does not like "Canon"

You can check the link in my above post about problems with bookmarks caused by a problem with the file places.sqlite.

tried your link but that did not solve the problem.
