I have a strange problem - I can't open files or folders from many third party apps - clicking a downloaded file in Chrome does nothing, clicking "Open in Finder" has the same result. Safari can open downloaded files but click "Show in Finder" also does nothing. Same happens in Fork Lift - can't view folder or files in Finder. Does anyone know how can I fix it?
 
Have you tried restarting your Mac?
Have you checked the permissions on the files/folders?
 
I haven't really read the log then. I remember only lots of iCal related entries (I installed a mod to restore "native" look). Will run it again to see what it will show.
What log? All you have to do to check permissions is right-click a file or folder and Get Info. The permissions are shown at the bottom of the Get Info window.

Oh, I thought you meant permission in Disk Utility. Well permissions for Downloads folders says that I have read and write access and everyone group has no access. Permissions for files inside says that I have write and read access while everyone and staff groups has only read access.

What kind of files are these? Get Info on one you're trying to open, then take a screen shot of the Get Info window and post it.

Downloaded from the internet: DMGs, images, APKs (Android apps), PDFs, ZIPs, etc. Here are some screenshots ("odczyt" is read, "zapis" is write, "brak dostepu" is no access):

Go into security in preferences and switch off sand boxing.

Well, I don't see an option for that here. If you meant the one about allowing apps from outside the MAS and without digital sign, it was already enabled.
 
What happens if you right click on the dmg file and select Open?

Files and folders open fine from Finder, but not from other apps like browsers. Chrome can't open both them, Safari and Fork Lift can open files but cannot open folders (by clicking "Show in Finder" option).
 
Perhaps try restarting Finder. It's happened to me occasionally for the past few versions of OS X, and that nearly always fixes it.

What about thinking back to when the problem started occurring, was there something you did other than that mod?

Odd. Open the Console app (Applications --> Utilities) and put it to one side. Then try to open the file from a browser and see what messages come up in the console.

Good suggestion.

Open the terminal and type in

Code:
sudo killall Finder

It should restart automatically, but if it does not, then type

Code:
open /System/Library/CoreServices/Finder.app
 
Restarting Finder didn't help. After clicking "Show in Finder" option in Chrome, Safari and Fork Lift nothing shows in the Console app.

The only thing I installed around the time the problem occurred was RCDefaultApp for changing defaults. But I haven't changed anything related to Finder, only multimedia files.

I suspect that RCDefaultApp or something else has broken the file associations, because your problem is not normal and I cannot replicate it with Gatekeeper turned off.
 
Try in a new user. Try in safe mode. Repair ACLs. Re-install the latest Combo Update.

Is there any way to reset them without reinstalling OS X?

EDIT: I will answer that question myself: it is possible and doing this + restarting my MacBook did the trick and everything works fine now. Thanks for help everyone.

Nice one. I was about to paste that in, but was checking to make sure it still works in Mountain Lion. I wasn't 100% sure if rebuilding the launch services database would do the trick, but I am glad that it fixed your problems.

For the benefit of others who are too lazy to click on the link: open Terminal and type in:
Code:
/System/Library/Frameworks/CoreServices.framework/Frameworks/LaunchServices.framework/Support/lsregister -kill -r -domain local -domain system -domain user
