I would like to observe the contents of a POST request whose successful completion results in a location.reload() - when I try to capture this request in the Network Panel of the Firefox developer tools, I find that the page reload clears the list of captured events. Can I prevent this clearing? wbamberg From Firefox 31 onwards you can use the " Enable persistent logs " setting to prevent the Network Monitor from clearing the list on reload. Despite knowing the name for the setting is "Enable persistent logs", it took me a while to find it on the settings page. I hope this helps: I couldn't

I just cleaned my Firefox addons and wondered: Which features does Firebug have that make it unique? Which features are available in both Firebug and the Firefox Developer Tools? Sebastian Zartner Firefox's native developer tools have come a long way since this question was written. The differences have mainly reduced to the following points: Can't stop the script execution on DOM mutations, XHRs, or cookie changes. XPaths can't be copied. Missing an events side panel in the Inspector (though events are displayed within the DOM structure). Missing a DOM side panel in the Inspector. No live

I can only see the .js files, the .ts sources don't appear in Firefox. It works in Chrome, I can see and place line breaks in .ts files, and the debugger works great. But Firefox will not work, no version, not the stable or the nightly or the developer version. Could it be that the functionality is not implemented on Mac/OSX? If so, there should be something on the internet about that, but I've found nothing. Apparently, the problem has not been documented anywhere. Does anyone have any knowledge of this, and perhaps how to fix it? A little late but hopefully helpful. For Firefox make sure

I decided to try out the built in Firefox Developer Tools. Seems to be nice, but... I can't find out how to add a new rule to the CSS from Inspector/Rules. By that I mean ".my-new-rule" not just the "element" rule that is open by default. FINAL EDIT: This is now possible with the latest Firefox update. Update: As of FF 33.00 it is now possible to add new CSS rules using the inspector! It is not possible to use the inspector to create new CSS rules with out a browser add-on (see comment below). Just use the style editor. Type anywhere to make a new rule: As of Firefox 33 (in nightly right now

I am new to Firefox extensions and i would like you to help me pack one extension that i build and send it to some friends to test it. My Extension is about to "block" some URLs. Which means that if someone tries to join "facebook.com" my extension should redirect him to "www.google.com" the code is below. const {classes: Cc, interfaces: Ci, utils: Cu, results: Cr} = Components; Cu.import('resource://gre/modules/Services.jsm'); var urls_block = [ //If URLs contain any of these elements they will be blocked or redirected, // your choice based on code in observer line 17 'www.facebook.com', 'www

I highly prefer the firefox developer inspector than the firebug one. But is that possible to display PHP logs in the native JS console ? Thanks :) I just installed Chrome Logger ( github | website ) with Chrome PHP to accomplish this in Chrome since Firefox 50+ broke FirePHP. I then learned that Firefox's web console has been supporting Chrome Logger since v43 ( https://developer.mozilla.org/en-US/docs/Tools/Web_Console/Console_messages#Server ). So in short, yes, you can log PHP variables to the Firefox web console using Chrome PHP. It's this simple: Download the latest Chrome PHP library:
