natively, which led to Microsoft implementing this feature in the next release, Internet Explorer 7. History and development NetCaptor's development began under the name SimulBrowse in 1997. SimulBrowse was renamed Netcaptor because the developer didn't like the name. Some of the browser's features were original, while others were inspired by similar products. According to a statement from developer Adam Stiles, NetCaptor was one of the first browsers to feature a tabbed browsing interface; while similarities were found in other browsers of the era (such as Booklink's Internetworks or Opera), NetCaptor's tabs were closest in form and function to the tabs found in modern browsers. NetCaptor was a closed-source program started and maintained by Adam Stiles. The last released version, 7.5.4, was made available on February 18, 2005. On a post dated January 8, 2008, Stiles officially declared that "NetCaptor is Dead" after 10 years, and "What a ride it's been". Stiles recommended that users switch to the Mozilla Firefox or Safari web browsers. He simultaneously released a free registration key for anyone still wishing to use NetCaptor, but due to the browser's tendency to phone home to check registration key validity and the dissolution of the website, the key no longer functions: BBLdOxhx2bovHIQ0pVZjaiTWmAuEjmPOUM3tsFTcNzb4kjXdiq0 P+wsLJp4BBuNKtYYyKyAuRRgp8h=REQ+7f2h3PfFIoZFH91P5On 6eppScyJ560Xjr1z9dQDcLj43LACA496IEz+jNAVeEOT7RfWph5 7tCk6ajYmLEFc5ODjy There is no legally provided workaround or modification available.
