In cloudflare, I have a firewall rule to only allow certain user-agents. This one is always getting blocked because I haven't allowed it but I am wondering if it should be allowed? Not sure if it's coming from a legit browser or some automated program?
Anyone know where it comes from?
Thanks
It's the nightly version of Firefox's new-generation browser on Android, Fenix:

I'm able to access the internet in other browsers except Firefox... After updating the browser I'm facing the issue. I tried by reinstalling the browser, still same issue I'm facing. Please, suggest me a solution. Thanks in advance.
I faced the same issue. I did all the things that they have listed in the mozilla forum for the same question and still it did not help.
It turns out, if your organisation is using a proxy, you might have to contact your admin. The standard answer in the mozilla forum is that you have to set the proxy setting to "none". But if your organisation is using a proxy then by default IE will have set the settings to desiganted proxy, but apparently mozilla has its own proxy settings.
So go to proxy settings in mozilla and make sure the settings there is similar to the one in IE. I set the proxy to detect automatically and it worked.
Hope this helps!
Did you have any anti-virus software installed? If so, please take a look at the following article from mozilla:

Is there a way to disable the same origin policy on the Mozilla Firefox browser by toggling a flag in the browser?
This is strictly for development, for not production use.
Please note:
A similar question asked 3+ years ago yielded an accepted answer that recommends users to install a plugin. I consider this less secure and more cumbersome than toggling a flag (e.g. in the about:config, or passing a parameter when starting the browser like in Chrome).
After having tried to find a Firefox setting for various hours, and after having opened a bounty, I think the right answer to this question is:
At the moment of writing (March 2018), it is not possible to disable the same policy origin in Firefox by simply setting a flag.
I would personally recommend people to use Chrome instead for this kind of work, because disabling this setting is very easy, quick and doesn't involve installing third-party software.
There is a boolean in Mozilla Firefox that should allow toggling of the same origin policy called security.fileuri.strict_origin_policy.
Go to about:config in your browser and accept the risk:
Then search for security.fileuri.strict_origin_policy and double click it to toggle it to false like so:
I have not tested this but in my experience, this is the flag controlling the same origin policy.
Rather than directly answer your question, this alternative might be viable if you also have ownership of the server
Get your server to add the following response header. (+ Apply a DevOps process or piece of code to ensure only apply this code during development)
Access-Control-Allow-Origin
.. With the value of your origin domain, e.g.
http://example.com or alternatively * for all domains.
So I wasn't able to do this using Firefox. I was able to do this inside of chrome using the following. My purpose was for testing endpoint access to a server without CORS being setup.
google-chrome disable-web-security -allow-file-access-from-files — allow-file-access
Your google chrome executable can vary to whatever you have linked it to.

I remember a plugin that could detect which OS and what programming language was used on the server side. I don't know anymore what the name was. It could be Firebug or something like that, but I can't find the function.
Firebug makes it easy to look at the headers send by the Server. But be aware, that server could fake or hide this parts of header, so it does not work always.
This is a Browser Plugin called wappalyzer http://www.wappalyzer.com. if you are using firefox plugins site just search for wappalyzer.
I've been having problems testing AJAX on my computer, the code works fine online but not on my system, is there something I am missing?
I've had this problem with pretty much any kind of AJAX and even some javascript code. I know the code itself is correctly since it's functioning online as intended, but why wouldn't run on my PC? Everything I am trying to do is basic coding, no database, or advanced functions of any kind, simple interface changes and such.
I don't have any specific code to post since its a general problem i'm having, but any thoughts are appreciated. Could it be a document type issue? I tried blank and a couple of others but none seemed to matter.
Ill bet that you are having a same origin policy issue. If you are loading the page by going to localhost:<port>/app and then your javascript tries to go to anywhere other than localhost the browser will stop it for violating the policy.
I have had strange problems testing AJAX locally before. To fix this I install ultidev's Cassini web server and run the application on that and it seems to work.
You need to set up a webserver with either php running or something like it. A desktop PC is not a web server by default.
I want to see each url request made my by browser.
I want to see the url requests made by ajax.
Which software should I use? Some java code would also help.
You can use Fiddler or if you need to "go deep" (as their web page says), you can use Wireshark.
Firefox has a great plugin called LiveHTTPHeaders that I think will get you what you are looking for. I'm not positive on the AJAX part of the question, but it's worth a shot. I consider LiveHTTPHeaders to be an indispensable tool for anyone doing web development.
Use Firebug
(source: getfirebug.com)
Otherwise use Wireshark http://www.wireshark.org/ if you want the swiss army knife of network capture tools.
There are lots of great programs out there that will do this. My answer would really depend on what you are trying to do.
Adding an HTTP proxy that logs requests will easily do the job.
You can also leverage browser plugins such as FireBug and Google's Page Speed to see the requests fly in realtime.

I don't really understand where do you want to see the traffic. But if what you mean is browser and if you are using Firefox then Firebug will come handy.
So many great extensions for Firefox that'll give you that info:
Firebug
PageSpeed
LiveHTTPHeaders
You could also try using the developer tools in Safari or Chrome if you're not a Firefox fan.
If you use IE... why are you using IE? ;-)
Any personal proxy will do. Fiddler was already suggested.
For Firefox I would use the TamperData plugin.
