I downloaded Qupzilla browser for a test drive. Download was easy and so was set up. Webmails like Gmail works fine. I found trouble uploading a pic to Google Plus profile. The computer reqources shot up and the browser hung up. So ‘Allow Netscape Plugins (Flash plugin)’ had to be disabled.
Posting a wordpress post has no problem. Editing a post is not a problem.
Opening a twitter account, uploading a pic went through without an hitch. I encountered no more problems with it.
Dowloader is a good feature. I think it speeds up downloads. It has speed dials like Opera browser. There is a RSS reader and a Web Inspector (you can analyse page elements). Overall a good light browser for simple daily tasks.
It has to be mannually updated.
