The version of my Adobe Flash Player in Chrome is: 11,2,202,229 and Chrome does not let you update it manually, it said Google Chrome will automatically update it when new versions are available, which according to the About Page, is 126.96.36.199 also.
I wonder if I have to wait until Chrome update its Adobe Flash Player before the one in FF will show the correct one, which to me, doesn't make sense.
I went to Adobe forum and found out that if you reboot your system after the update, Firefox will display the correct version. Nobody knows if it's Firefox or Adobe problem because it should not be necessary to reboot the system after a simple update like that. But that's the solution.
