I did have a chance to download and install OPERA 35.0.2052.0. Developer Edition with free VPN. Opera states that they are the first major browser maker to integrate an unlimited and free VPN.
I installed and ran Opera Developer Edition with no glitches and it does run rather fast even with the VPN enabled. However, I found that Chrome will not connect to the internet while Opera is installed on my HP desktop running Windows 10 Pro. I am not extremely surprised as Opera and Chrome are both running “Blink” web browser engine developed by the Chromium open source project. “Blink” has had contributions from Google, Opera Software ASA, Intel, Samsung and others. I am unable to run Chrome even if the Opera Developer Edition is not running at the same time.
At this point I assume that the VPN component on Opera is not compatible over the same network connection as Chrome. I had no problems running Firefox, Edge, or IE while Opera Dev. Edition was installed. Ultimately I had to uninstall Opera Dev. in order to get Chrome back online. I am deciding if I want to try Opera in place of Chrome due to no other known conflicts with other browsers that I’ve installed.
In contrast, I have had no problems running Chrome Developer side by side with Chrome nor have I had issues running Firefox Developer side by side with Firefox. I am able to run “Opera’s Standard” edition (no built in VPN) side by side with Chrome. I have had success with all of these combinations on Windows 8 and 8.1. as well.
