The programmers are working on the problem. Please disable Internet Download Manager.

hi, unfortunately these crashes are probably triggered by malware that's present on your system and hooking into firefox (a lsp monitoring your network traffic labelled "chtbrkg.dll"). please go to the windows control panel / programs and remove all toolbars or potentially unwanted software from there (especially anything dubbed "adskip" or other programs you haven't installed intentionally). then please also try running security scans with various other tools like the free version of malwarebytes, adwcleaner & eset online one-time scanner.
