So does my son. I'm currently using older versions of Firefox/Cyberfox because the newest releases not only disable all my tried and true plugins/addons without any replacements for them, the new formats are freaking UGLY! My son is getting the "We will be disabling this version of Skype, so update now!" Problem is the version he's using now works better than the "new and improved" version.
I get fed up with all the excuses/reasons "To ensure your security" or safety. Bollix! It's up to ME to take care of that, not Microsoft, not Mozilla. That is what 3rd party security software is for.
So, until Microsoft releases a better version of Skype, one that doesn't have that gawd awful Facebook Messenger layout, or gives one with a customizable layout, and until there are updates, or REAL replacements for current browser extensions, I will stick with the 'old and lousy' over the 'new and improved.
