Once again - I open a browser, I press "editing" - "adjustments", into adjustments to come it is possible. At attempt to change something in adjustments, the browser hangs also to me it is necessary to finish its work compulsorily.
Further, I try to add page in bookmarks - literally after 1 second the browser finishes the work. But the page in bookmarks can be added and by means of " the Manager of bookmarks ", in this case the browser continues to work, but it is very inconvenient.
At attempt the Downloading file appears a window with a choice of preservation of a file, then the browser either hangs, or takes off, and I should finish its work manually.
