I hope I am asking a question that fits Stack Overflow standards. I am curious to know from web developers point of view, what do you prefer Firefox or Google Chrome. Is Firefox or chrome your best choice of developing web apps and websites. Which one do you prefer and why.

I prefer Firefox, as I find it easier thanks mainly to the Web Developer add-on, and a few others. Interestingly, a recently-leaked Google document for internal testers said they had to use Firefox.

Chrome, its built in dev tools are easily as powerful as Firebug, yet no need for an extension.

Chrome also loads up within a few seconds, while Firefox still takes an age to startup, that really bugs me!

I use VPN browser extensions and therefore there is a different proxy on my browser than the whole system.
I want to see what exactly is the proxy information (port and address) used in my browser. How can I do this?
The browser I use is Edge and Chrome, and my operating system is Windows
You can log your network activity and find out your proxy setting within the json file. Just go to:
For Edge: edge://net-export/
For Chrome: chrome://net-export/

we have built mac and windows desktop version of our app using electron framework, but it hangs and become unresponsive really often. Using chrome natively it does not happen. Is there any flags that needs to be added/removed when using electron framework, and what could be the difference? The biggest problem that I don't have knowledge how to debug these kind of problems, because logs does not return anything before hanging, and profiling becomes unresponsive too. Any suggestions?
Thanks!
You can open the Chrome Developer Tools with
require('remote').getCurrentWindow().toggleDevTools()
From there you can profile it like a normal webapp, you can take a look there what takes much time. There are many good tutorials how to use these tools.

Since I dont have a Mac and dont have much experience (couldnt find any infos either)...I would like to know if Javascript in Mac is disabled by default if using Safari or any other browsers.
Im asking because it happened once that one or two users told me they couldnt access some of my sites features (all javascript) and that they are on a mac.
No. All of the mainstream OS X browsers support JavaScript and have it enabled by default.
It works perfectly in all those browsers, essentially firefox 19-30+, Safari 4-7+, opera 15+, chrome+. They display downscaled images fine as the rendering engine improved. You can always display a fallback using SVG if rendering is ugly using javascript media queries.

I've downloaded Canviz (it's a Javascript library for drawing graphs). I've unzipped the archive. I open, with Chrome, index.html, which is supposed to be an example. A "loading" message appears... and never disappears.
What am I supposed to do please ?
I worked with this library a few months ago.
You also need to have graphviz installed in order to create the graphs canviz will draw.
When you have installed, you have to use the function load with the url parameters in order to create the graph.
WebBrowsers have an option to enable javascript or not. make sure your browser enable it.
here's an example for Mozilla : Mozilla example

I use MDN as my Javascript and CSS reference. Considering that the creator of the Javascript language works at Mozilla, I assume this is the best reference. However, every now and then I hear about new features that are available in Google Chrome but Firefox doesn't have them yet. It makes me wonder:
Where and how these new specs are announced?
For the things that are similar between Chrome and Firefox, is it safe to assume that Chrome follows Firefox standards? I get the impression that Chrome's main aim is to be a faster Firefox (?) and that's why it doesn't have a vast wiki like Firefox.
If I'm developing for Chrome (let's say making Chrome apps for example), can I rely on Firefox's MDN as a reference? I couldn't find something equivalent to MDN for Chrome.
I'll mark the best reply as answer. Thanks for sharing your knowledge.
All modifications are announced in the google chrome release blog.
As far as I see it, chrome isn't just a faster Firefox. It's a different browser altogether, that provides, in my view, much better user customization (as seen in things like themes) as well as having a developer base which provides some really good extensions. As to the wiki, chrome is considerably newer, however, it provides some really good user support via chrome support.
AFAIK, spidermonkey (Firefox) and v8 (chrome) engines are reasonably similar in terms of javascript, so you should be alright just using MDN. There's a webmaster.SE thread about the issue here.
