My apologies, but I seem to be having difficulty with the Opera Addons webpage recognizing Opera GX as a valid and official Opera build to enable Addons downloads. When I visit the page, it treats it as if the user agent is a Chromium-based browser not specifically in the Opera family of products, and does not show the download button for users; only a link to download the original flavor builds of Opera. Below, I will state my current OS and system for parity's sake:
Operating System: Microsoft Windows 7-x64 Professional, Service Pack 1 (Build 6.1.7601)
Opera Version: GX LVL 1 (Core 66.0.3515.111)
System: HP Elitedesk 705 G1 Desktop Mini
Processor: AMD A10-PRO 7800B R7, Quad-core Processor (Kaveri chipset)
Installed RAM: 8 GB
Installed Opera Extensions:
- Install Chrome Extensions (Version 2.5.9) by Opera Software
- Opera Ad Blocker (Version 66.0.3515.111, included with browser) by Opera Software
- uBlock Origin (Version 1.23.0) by gorhill
- Weather (Version 4.3.247) by Tim Leland
I'm not sure if these details may help, but for parity's sake, I'm listing them here, as I've found it's customary to do so when reporting issues with computer programs in the past. I do enjoy the GX flavor of the Opera browser family, and I hope dearly that everything is ironed out for the major official releases. Thank you, regardless, for your time and allowing me to voice my concern and feedback!
