I'm using firefox developer edition. The latest version: 76.0b2 I have firefox.cfg set up to overwrite new tab content with locally stored html. The code in firefox.cfg that worked until recent update:

/* set new tab page */ try {

 var newTabURL = "file:///G:/Documents/Newtab.html";
 aboutNewTabService = Cc["@mozilla.org/browser/aboutnewtab-service;1"].getService(Ci.nsIAboutNewTabService);
 aboutNewTabService.newTabURL = newTabURL;

} catch(e){Cu.reportError(e);} // report errors in the Browser Console

In the browser console there is an error message displayed:

[Exception... "Cannot modify properties of a WrappedNative" nsresult: "0x80570034 (NS_ERROR_XPC_CANT_MODIFY_PROP_ON_WN)" location: "JS frame :: firefox.cfg :: <TOP_LEVEL> :: line 7" data: no]

Any idea what that error message means and how to resolve it? Does anything changed regarding new tab overwrite?

I'm a software developer working on backend services, always juggling between Firefox and Chrome (because none of them fully satisfy my needs). What I need from them is to behave the way it will be most practical for me, which isn't necessarily aligned with the majority of users.

My current problem is this. I work with APIs which in my daily work often return various HTTP errors. These errors also contain a payload which describes the problem in detail. I want to be able to see this payload easily in the browser. Yes, I can use other tools like Postman for this (which I do), but for simple GET requests without special request headers it would be much more practical to just use a browser.

Currently, when my API opens an error (for example a 400 Bad Request), Firefox decides to just silently go back into the previous page (undos the URL change). If I open the Network tab in the Web Developer view, I can however see the failing response with all of its details. Still, this is too impractical for me.

BTW, the response contains a custom Content-Type which isn't recognized by Firefox by default. But Firefox isn't downloading the payload as a file (like it would usually do for a successful page load of an unknown Content-Type), it just silently doesn't do anything. I've installed an extension to handle my custom Content-Types (called "Open in Browser"), but since Firefox isn't attempting to open this one, I can't use it in this case.

So, how can I force Firefox to stay on that URL and show the response payload in the window? If not in vanilla Firefox, any plugins? I've already kind of spent too much time on this for my liking. :/

Imagine that I'm on a website like example.com and I click a button. Looking at my browser's network tab, I can see that the page has sent a POST request to example.com with some data and received some data back from the server.

I want to be able to:

  • Edit the data before it is sent to the server.
  • Edit the response data before it is handled by the function.

I'm aware of Firefox's "edit and resend" feature, but I want to tamper with the very first request before it reaches the server.

I've been searching for this for hours but all of the answers appear to be outdated due to browser updates. What is the modern approach to doing this?

My Firefox Developer shows "no element selected" under Inspector after refreshing the browser for few times.

Update on 8th September

The issue always happen on Mobile Responsive Mode, I tried to uninstall all the extension but it does not help.


I don't think it is my computer issue because my office computer runs into the same problem as well.

Is this a bug?

Worked fine last week.

My local webconfig has the redirect to HTTPS rule disabled. So I am going to localhost, at least not with FF Developer or regular FF has the same error.

Works fine on Chrome and Opera.

Note: I control the server. The following is noted on the client:

Your connection is not secure

The owner of [myDomain] has configured their website improperly. To protect your information from being stolen, Firefox has not connected to this website.

And yet, an online cert checker states: Congratulations! This certificate is correctly installed.

So, the obvious answer is it's a caching problem. I found 2 cookies from the old domain that I deleted and then cleared the cache. No luck. *Yes, old domain as I now have a new domain. It sees the old cert for the old domain, which I have revoked and deleted with "certbot revoke". Using Letsencrypt on ubuntu 16.04

Thank you in advance for any help!

Hello, I am involved in developing an application that uses WebRTC for video calling.

Prior to yesterday my FF browser was at version 61.0.2 and the application could make video calls between FF / Chrome and apps running on Android and iOS

Today, I was unable to make calls to/from FF 62.0. Calls made using Chrome to Chrome work fine. Two colleagues were also able to make calls with older FF 61.0.2 and then no longer, after upgrading to FF 62.0

We are using the PeerJS library

What WebRTC related changes have been implemented between 61.0.2 and 62.0?

Thank you

The wrapping problem does not occur in the other browsers I have tried. I also looked at the page in Explorer and Edge. No problems there. I do not have Chrome installed. Look at these examples:

Narrow your browser window until you see the problem in Firefox.

I am updating some css code on my Wordpress website. When I update the code I see the change on all internet browsers EXCEPT for Firefox. I know all about emptying cache and cookies and history and that is not it. I have opened the website on computers that have never even been to the site and it is still pulling my old css code! Now, I was making some changes last night and Firefix wasn't updating the ocde, but when I looked at it this morning the changes were there. Does the changes take longer to reach FIrefox browsers or something? I am not the MOST savvy web designer, hence the Wordpress website, but I have changed my css code a thousand times and I always see the updates on other browsers. Please let me know if it is a "delay" thing with changes to Firefox or if I need to add some sort of special Firefox code to the css.

Appreciate the help and I apologize if I am just a missing something easy.

Hi,

the css animation of the svg:circle looks weird. It seems that the size of the bbox does not follow the size of the circle itself. As a result the circle from time to time is cut at borders. I have not faced this problem with other browsers. The problems seems to appear on Windows 7/10 only. On Mac this looks better.
