User Agent: Mozilla/5.0 (Windows NT 5.1; rv:8.0.1) Gecko/20111121 Firefox/8.0.1 SeaMonkey/2.5 Build ID: 20111121045514 Steps to reproduce: If I make a right mouse click to open the menue and choose Search with Google for ... it happen nothing Actual results: See above and screenshot Expected results: See above

Does it work if you restart in Safe Mode? Help | Restart with Add-ons disabled Does it work if you were to create a new Profile? Tools | Switch Profile... Appears that by default, the context menu should also be showing a "Properties" menu item?

In Safe Mode it works, but if I delete each single Add-On - it changes nothing! It doesn't work since Seamonkey 2.4

Edit->Preferences->Browser->Internet Search What are you settings for: Default Search Engine and Search Results

That will change nothing (see screen shot). This command is not editable, but all other comands as "show source code" a.o. do work.

I have just made a downgrade to SM 2.1 ... here it works, so ...??

I didn't ask you to change your internet search settings. I just asked you for your current settings in Comment 3.

Well, of course Google is my standard search machine.

If I change the search machine, the context menue shows the new search machine, too. So the setting for the standard search machine aren't the reason, even if I use Yahoo etc.

First go to about:config (from the urlbar/address bar) Filter for javascript.options.showInConsole if it is false toggle it to true by double clicking on it. Open the error console. Tools->Web Development->Error Console. Clear any existing errors. Try doing a web search again. Look at the Error Console to see if there are any relevant errors.
