If you’re a Safari user who has installed OS X 10.11 El Capitan, you may run into a troubling issue when saving images in both Pixlr Editor and Pixlr Express: Your browser may freeze. Over time, Apple has restricted how Flash apps work in Safari, in some cases restricting Flash apps from saving to a local directory. This is an issue we are pursuing with Apple, but for now it’s a known issue that is outstanding.
Luckily, there is a workaround. You can, of course, switch to using Chrome or Firefox to edit images in Pixlr Editor and Pixlr Express. But you can also set Safari to allow Pixlr apps to complete saves. Here’s how:
First, open a tab to Pixlr Editor or Pixlr Express or simply visit pixlr.com.
Head to Safari > Preferences and choose the Security tab. Click on Plug-in Settings.
Adobe Flash Player should be automatically selected if you have visited pixlr.com. Change the settings for pixlr.com to “Run in Unsafe Mode” and click the Done button.
That will allow you to run these Flash-based apps in Safari. Of course, we completely understand if the phrase “Run in Unsafe Mode” scares you into using Chrome or Firefox instead!
