The error message is: what happened: Type Error: Components. classes ['@mozilla.org/extensions/manager;1'] is undefined.

That indicates that you are using an add-on that is not compatible with Firefox 4. For details of how to troubleshoot that see https://support.mozilla.com/kb/Troubleshooting+extensions+and+themes

Thanks a lot. The Ask toolbar created this problem. Another problem is: When searching on the web via Google, normally it is possible to type a few letters and then look what appears and then click on the wanted word(s). A number of word(s) ineed do appear, however it is not possible to select any of them as ws possible as mentioned in olders versions.
