PSA – Safari 13.0.1 breaks multiple extensions

Even if you’re still running macOS High Sierrra (I’m on 10.13.6) you’ll receive a Safari update (from 12 to 13).  This will break a number of extensions – including most adblocking – also a vim-based keyboard extension I was using called Vimmy.

So you may want to avoid upgrading, or do as I’ve done and switch your default browser to Firefox etc. for the time being.

Tips: Updating the Adobe Flash plugin for Firefox, Safari, Opera on Mac

I’ve routinely found the standard Adobe Flash player updater for Mac (OS X/macOS) fails right at the end, without explanation.

However there is a version that always works. Go to:

https://helpx.adobe.com/flash-player/kb/installation-problems-flash-player-mac.html

… and choose Flash player for Safari and Firefox – NPAPI – the download URL is normally:

https://fpdownload.macromedia.com/pub/flashplayer/latest/help/install_flash_player_osx.dmg

The opening dialog box should look a bit different – like this:

Adobe Flash Installer

Opera users

Use this version (last tested 10 Feb 2017):

https://fpdownload.macromedia.com/pub/flashplayer/latest/help/install_flash_player_osx_ppapi.dmg

Firefox plugin checker

This is a very fast and handy way of seeing if your copy of Flash or Silverlight is up to date.
