Love the new features. I still find myself using Firebug over the built in dev tools in either Chrome or Firefox. The Firebug team has done a really tremendous job over the years. Keep up the good work!
Yeah, firebug still has quite a lot of polish compared to the others.
Perhaps it has to do with the contributors being expert UI developers, and firebug developers second. Whereas the other tools are mostly developed by employees who do full time dev tool development, but not so much work using the tools.
But I know others mostly prefer chrome tools. The same people often get stuck in firebug or in IE dev tools.
I fail to see how Firebug has a better UI then WebKit Developer Tools?
As far as I am concerned they are the same in that regard. And since both of those tools are not built by "developers", but by "frontend engineers" it doesn't really matter.
I spent like 15 minutes trying to figure out how to attach Firebug to the browser window. Only to find out that the upward pointing arrow in a gray circle means attach to browser window. On WebKit I click an icon that looks like a browser window with developer tools.
The resources tab in WebKit is ten times better then the mishmash of CSS/Script/Net/Cookies tabs all spread out.
Anyways that is just my opinion, and as far as I am concerned Dragonfly was the best.
I guess it comes down to personal preference but I've always thought Firebug beats Elements and Resources in Chrome. It is much faster to filter with tabs than digging through a tree IMO.
Think what s/he's saying is that it helps that they use their own tools for UI dev versus those who hammer on the browser and made comparable tools, not that Firebug has a better UI.
It's true.. the Chrome DevTools are a webapp, and the engineers behind it use the DevTools _on_ the DevTools as their primary means of development. (Enter inception joke here). From what I can tell, the same is true with the Safari Inspector and the IE F12 Tools.
Even the cookies. It's been in webkit for a while. SO USEFUL.
You can also use it to leech stuff from login/captcha protected download areas like rapidshare or the apple dev center. No more failed browser downloads of 1gig files! Just add -C to your curl command!
Well Chrome had this feature for a long time. Personally I don't find it much useful. But to me the killer feature of firebug is that when you open an XHR entry in new tab it opens the tab with all POST variables. Super handy when debugging REST api.
Very annoyingly, in the FF 24 beta, Firebug basically crashes the browser every time you open it (or switch to another tab and then back). Not sure if it's FF's problem or Firebug's, but it's really annoying.
Interesting, you don't have lag when first opening it? I was investigating pretty much the same thing yesterday, in the end my problem was that the JSD was ridiculously slow to toggle, but firebug is already working to move to JSD2 so I can't really complain too much. There is a test extension you can use attached to this bug.
I was getting something like 100ms to pause and 10000ms to unpause. With 5 tabs loaded and a couple hundred tabs unloaded. I disabled the javascript parts of firebug for general use, which does avoid the problem most of the time.
Aha, you're right! Disabling the Script tab helps immensely. It's a shame since I need the Script tab for a lot of work, but it's not too much of a pain to disable/reenable.
Crashes and slowness that vary with Firefox versions is Firefox's fault, and in this case the note about tab switching points pretty clearly to a problem with the debugger service.
When you enter debug mode in SpiderMonkey most (all? I forget) jit'ing and optimizations won't happen; code becomes a lot slower. The new debugging api allows you to debug specific tabs, while the old one would force all of the browser (including the chrome js that handles the browser's UI) to enter debug mode and the whole browser gets slow.
Because Honza is working on porting firebug to the new debugger API, it will get faster, and so will all of firefox when you are using firebug.
IIRC, Honza is not just working on porting from the old api to the new one, but also on top of our remote debugging protocol. This means that we improve the debugging server, and both the native tools and firebug get better. Plus, you'll be able to use firebug on your laptop, connected remotely to firefox on your android phone, or firefox os.
Not really, no. There was some talk about adding a Firebug panel to the built-in tools, but nothing has really come from it, and any deeper UI integration is probably out of the question for being too much work. But suggestions about how to make it better are still welcome, of course.
The main thing we have gotten out of the new devtools are new cool APIs, e.g. for debugging, paint flashing, CSS auto-completion, profiling (though we haven't gotten around to using most of them yet).
