Flashblock for Firefox
Handier than you’d think
Flash on linux has a problem. It is always the top layer. These days many web sites - including my bank and my airline, have flash windows that overlap their design boundaries in the style sheet and they rely on flash being cropped behind the other layers. Its bad design of course but I found a way to solve the issue on my own.
Out of desperation I sought out and found This Firefox extension that disables flash until you click on it. Originally I just needed it to access the Delta site as their flash was blocking the login box - but surprisingly this add-on has proven to be a real improvement - even on Windows.
You should install Flashblock and take it out for a spin. No more flash ads - everything is in its place. Your computer fan doesn’t kick up when you go to a web page that’s overburdened with flash. You really don’t even notice its there, but your browsing experience improves dramatically. If there is a flash thing you want to see (like a YouTube video) you can add YouTube to the whitelist or just click the “f” logo and watch.
