is uPlexa compatible with all browsers?
When you say 'uPlexa', are you referring to the website?? In which case, yes, we've all tried it on multiple platforms and any small fixes will be implemented immediately.
If you mean something else, please let me know!

I think he means how does one mine with a browser. The thread title "browser based" implies browser mining. What is the meaning of "browser based" here?
