Vest on the left is a modacrylic flame resistant vest. Vest on the right is a 100% Polyester treated FR. As you can see, the vest continues to burn, melt and drip long after the flash. Note the flame burning next to the mannequin head. Both mannequins are wearing flame resistant undergarments.
VERDICT / Despite some compatibility conflicts, Opera is a secure, fast and feature-rich internet browser worthy of your consideration. Having started back in 1995, Opera stands as the second-oldest web browser currently in use. This software runs on a Google Chromium system.
Opera started out as a research project in Norway's largest telecom company, Telenor, in 1994, and branched out into an independent development company named Opera Software ASA in 1995. Opera Software develops the Opera Web browser, a high-quality, multi-platform product for a wide range of platforms, operating systems and embedded Internet products. In addition to the web browser, the other main component in the Opera suite is the Opera Mail client, previously known as M2. Opera Mail supports regular POP and SMTP mail as well as IMAP. It also has an Address book. Opera Mail also features a newsreader and a newsfeed reader for RSS and Atom, as well as an IRC client for online chat. The forthcoming Opera 9 will also feature widgets as well as further BitTorrent functionality.
