Can you recommend a tool to create bootable USB flash drives from ISO images? Howard Scott
Try Etcher (https://etcher.io/), which simply asks you to select your source file and target drive (SD card or USB flash drive) and then does the rest.
Can you suggest an alternative to the Fireshot browser add-on for capturing screenshots of web pages, please? Kris Edwards
Both Firefox 56 and Opera 48 have introduced built-in screen-capture tools – look for the scissors icon (Firefox) or the camera icon (Opera) in the either the toolbar or sidebar.
