New zero-day exploit hits fully patched Adobe Flash | Ars Technica best solution uninstall Adobe Flash 2nd best solution disable Adobe Flash or block it using noscript
Flash is evil, always was, always will be. thank god there is not really a need for it anymore now with HTML5
If you are using Firefox, just go to addons management and under your plugins you will be able to change the setting to enable, disable or ask you to activate the plugin. Also, do not visit strange websites. This exploit appears to mainly be targeted at .GOV types, and Adobe is expected to release a patch soon anyway.
Many sites are moving away from Flash and using HTML5. If you uninstall Flash, it will (in a roundabout way) encourage more sites to use HTML5 -- because they keep stats on visitors. If they see you can use HTML 5 but not Flash, they throw more support behind developing HTML 5. Most importantly, whichever browser you use, just keep it up to date. Chrome v.42 and Opera v.29 score best on HTML 5 tests. But HTML 5 is also supported in Firefox 37, Safari 8, and IE 11. Those are in decreasing levels of support -- so if you are using IE 11, your HTML 5 support is pretty bad.
