itunes 12.4.3 redirect me to safari

Hello,

Very strange behavior very recently within iTunes 12.4.3, the iTunes Store redirect all clicks (iTunes link) in Safari (6.2.8) instead of viewing the selected content in iTunes itself… (usually it's the opposite), I cannot load any more content from the iTunes Store to iTunes (OSX 10.8.5, iTunes 12.4.3, I know… this is a very old osx…)

Any ideas to fix this ?
