Some browsers ( with their latest builds ) has some issues, so sometimes using an older version of browser can help.

Sometimes you need to check your File System, by the repair tool to be sure that it contain no issues, as if there are any issue with the FS, then creating a new volume may take a longer time, and it's not recommended to keep working with a FS that contain issues. to check it, you can run \"Repair file system on LV (Logical Volumes)\" in Console Tools mode, after pressing (ALT+CTRL+X).
