Latest versions (2.x) dont work so good, it seems impossible to remove breakpoints in js and this is a frustrating problem still not fixed (tested on Ubuntu 14)

It's little bit complicated - first few hours with firebug can be frustrating, but it's learning process.

The new version is terrible! Rated 1 out of 5 stars

I'd score minus stars if I could. The old version of firebug was perfect. I used it everyday and it enriched my development life. This version is beyond terrible! Breakpoints are hit on code that isn't running, which is confusing. The option to break on error resets all the time, which is annoying. It's slower, the syntax highlighting is wrong and it crashes all the time, hanging firefox. If you need a good web debugging tool - downgrade to 1.12.8.

Firebug is a required addon for any webpage developer.

Note as of FireBug 2.0.4, there are major issues with JavaScript debugging. You will need to manually install the previous version FireBug 1.12.

I've been using Firebug for 4 years now. Since Firebug 2 was released, I can't debug my code. The debugger stops at breakpoints that don't exist anymore, the error console doesn't display syntax errors, it freezes Firefox from time to time. Firebug 2 has turned my favourite browser dev tool into a total piece of shit
