How do I allow Mozilla Firefox to use internet? [closed]

At my school Mozilla firefox is blocked for students, so only teachers could access it. The PCs are running on Linux Gnome. It has nothing to do with the cable, network manager or ifconfig eth0 up. It is only in Mozilla. You think it could be somewhere in Mozilla‘s settings (no proxy is used) .

As I was 12 I went in a IT Academy, where we had the same thing, so we couldn’t play any Flash games. We fixed it, by changing port in Mozilla in the right one, which people have seen once from a teacher.

I am saying it, because I couldn’t find the same option in the settings now.

Any information would help, thanks!

What use would a privacy browser, such as Firefox Focus for iPhone, have for an internal web server?

The Mozilla Foundation has a “privacy browser” called Firefox Focus that is available for example iPhone (here). This browser has an always-on ad blocking function.

I was checking the third-party licenses used by this iPhone version (image shown below) and noticed that it includes the use of GCDWebServer.

[3rd-party licenses used by Firefox Focus]

The GitHub page for GCDWebServer says that:

GCDWebServer is a modern and lightweight GCD based HTTP 1.1 server designed to be embedded in iOS, macOS & tvOS apps.

There is a support information for this browser here but the documentation does not mention the use of an internal web server.

This issue has relevance in evaluating the risks from possible open ports in connection with determining whether to allow this browser in corporate bring-your-own-device configuration.

Question: What use would a mobile device web browser have for running an embedded web server?

How can I trace/debug the origin of a specific POST/JS variable in JavaScript in Firefox?

Premise: I’m trying to automate posting on Stack Exchange. Not for abuse, but to have my own interface instead of having to bookmark and use the various “StackSites” and being subjected to the insulting “Viewed 1 times” bug which is never fixed no matter how many times it’s reported.

I have everything ready except for one small detail: the POST variable “i1l” is only set through JavaScript, in an extremely convoluted manner, to the point where I’m convinced that it is specifically done to stop any kind of automation. (Also, to make it clear, SE prevents any client that doesn’t have JavaScript enabled from posting at all.)

I asked about it previously here: https://stackoverflow.com/questions/59306239/how-do-i-make-sense-of-this-apparently-deliberately-obscurified-js-code

One of the comments mentions Stack Exchange apparently being open source now, and links to a GitHub URL, but I searched all over it and found no mention at all of this variable. It’s only present in the (heavily minified/obscurified) JavaScripts loaded on the actual site. So clearly it isn’t open source after all, at least not fully.

As it’s a complete mystery to me how this variable is determined, and it needs the right value or else it doesn’t let you post, I’m wondering if somebody can tell me how to “debug”/trace this specific variable in Firefox.

I cannot use their API because it requires you to have an account and only use that, which is not good for privacy. I want to be able to “ask as guest” for the StackSites that support it, and the API doesn’t let you do that.

I frankly doubt it would help me much even if I could follow this variable around, step by step, because the JS code I have dug up seems absolutely nonsensical to me. The very name is extremely cryptic and nothing indicates what it would be used for if not to prevent people from posting.

Note: Even if I were to abuse this, which again I’m not, the “one post per IP address per 90 minutes” limit, as well as the constant “too much abuse from your network, sorry” messages make it nearly impossible to abuse anyway. I get those constantly when trying to post perfectly legitimate questions.

Site collection is not working in IE11 but works in Chrome and Firefox

I have a site, which was created using sharepoint online, that works fine on Chrome and Firefox but not working in IE11. It works fine once I change the document mode (in developer mode) to 11 instead of 10. Not sure how to make it work without changing the document mode as this is not a solution (Can’t change this setting for the computers of anyone who visits the website).

401 error accessing SharePoint in Firefox on mac

I’m currently getting a 401 error when I try to access my SharePoint site on Firefox on mac. Usually when I login on a windows computer using FF I’m prompted to enter credentials, but for some reason I am not prompted on the mac? Does anyone know how I can get it to prompt for credentials?

Update: The mac is not connect to the domain, but it is connect to the network through wifi.

Opening VS Code makes Firefox freezed for a minutes in Linux Mint 18.3

I use Linux Mint 18.3. After opening a firefox window, opening VS Code made the tab in firefox can’t be shown correctly. after switching tabs, Firefox showed nothing but a throbber.

Firefox only shows a throbber

and the processes loading table is shown below (Web Content is about firefox).

After some minutes, Firefox could be manipulate properly.

Where does the bug from? How to solve the problem?

version info:

$ firefox –version Mozilla Firefox 69.0 $ code –version 1.36.1 2213894ea0415ee8c85c5eea0d0ff81ecc191529 x64

Apparmor enforce mode prevents Firefox from reading U2F security key

When the default apparmor profile for Firefox is set to enforce mode, it blocks Firefox access to security keys. Disabling the profile restores access.

Rules that I’ve tried and failed:

  • /sys/devices/** r,
  • #include <abstractions/dbus>
  • dbus send bus=system path=/org/freedesktop/RealtimeKit1 interface=org.freedesktop.DBus.Properties member=Get peer=(name=org.freedesktop.RealtimeKit1)

Can someone help me craft rules to allow Firefox access security keys?

Weird issue with Firefox toolbar

Since Firefox 57 (I’m currently on 69) I’ve been having a weird issue with its toolbar. When I open the browser, sometimes it looks like that:

Weird Firefox toolbar with no add-ons on startup

Every time that happens, I have to go to the 3-line button on the far right, then “Customize…” – by the time I do that, the toolbar backs to normal. Like this:

I want to solve this bug somehow, as it’s really annoying when I have to do this workaround sometimes. I want my entire toolbar, with all my add-ons, as it’s always supposed to be, every time. Is there some fix for that?
