Every link starts download in browser on my osx After cleaning my keyboard and track pad with and hot cloth (It was greasy), I'm not able to browse any links in Chrome, Safari on my mac book air with El Capitan osx.

When clicking any links on any website, it always starts an download with "download.html". I'm able to browse by right clicking on track-pad and choose "open in new tab", which is very annoying in the long run.

I have somehow managed to alter some config on my machine, but don't know what I have done.

I have tried to google this problem but I don't even succeed in asking the correct question, every result on google returns my with some irrelevant subjects.

Any help would be greatly appreciated
If your cleaning project stuck your Option key, such that Safari thinks it is always pressed, then any link you click on will download instead of open. 

So, try wiggling or drying around your Option key?
