    Great browser. Im running cyberfox v35 x64 and have a problem with the addon, random agent spoofer. It wont start when i open cyberfox, when i start cyberfox i have to go to extensions and disable and enable it to start it correctly. Please fix this! All other addons works great. Oh i almost forgot, the addon works without any problems and starts correct when i open Firefox v35 x86.

    Cyberfox gave me back what Firefox no longer offered: Choice of which working environment I like best. Where Mozilla has taken a wrong turn, 8specstudios' developers stand by their followers. Unlike Mozilla the 8specstudios' developers actually also give support to their end-user base. Thats why I support them in return. Cyberfox itself is a 64-bit web-browser for the Windows operating system. The advantage of 64-bits for me is the fact it is able to optimally take advantage of the RAM('s) on my PC exceeding 3 GiB's, but I hope it will never actually need to use (much) more than the 500,000 K private bytes it is using right now.

    I think it is a dumb idea to use its own profile. It was brilliant until version 28 when it still shared profile with Firefox. Nobody wants to maintain multiply profiles. And remember that a variant can never completely replace the genuine.

    Great browser, but still has the same problems as Firefox, Waterfox, etc. Downloading of large sized pngs and jpgs always causes the browser to crash. It doesn't seem to matter whether IP settings are optimized or not. So I'm thinking it's to do with the way the cache handles memory. Other than that, I love the program and it's features. I just hope that you eventually get it right with the problems that cause the browser crashes. Using Windows 7 x64 with SP1 by the way and running an AMD 9590FX CPU with 16Gb of memory at 1866Mhz. Just wish Microsoft hadn't chosen to rely on virtual memory so much. Best of luck with future updates and keep up the great work.
