Please, make a proofread of the following text and correct the grammatical mistakes and solecisms. I'd like to make a complaint, however I don't want to be insulting or ridiculous. Dear Sir/Madam! I'm using a Chromium based web browser, called Comodo Dragon, and the Google translator under it. I am very pleased with its quality and functionality, but unfortunately I am unable to use the reading aloud feature (listening the pronunciation). I am unsure if this malfunction has been caused by my browser or it is the deficiency of the software, so I would like to draw your attention to this problem, as you could check it over. Best regards, Robert! Thank you for your help!
