I am developing a web application that requires the use of service worker from firebase messaging, before updating to firefox quantum version this was working fine, localhost was the url for testing and i also saw the correct results on the production url site, just after doing the update for quantum this stopped working and i don't quite know why it isn't working as firebase only throws a messaging saying that it is unable to register.

OS: Linux Debian/Ubuntu 16.04 x64 Browser: Firefox quantum 57.0 (64-bit)

We have a client that used to run on local computers running the latest ESR version, they recently changed to a terminal server environment and during the setup 59.0.1 made it onto their new setup. Multiple issues have arisen that were not present on the old system and we need to move them back to the ESR version on the terminal server environment. I read online that you cannot just directly import any profile versions 55.0 and up to earlier versions so I am asking if I can instead use a mozilla account to sync over their data instead without causing a catastrophe, and if anyone happens to know what I might expect afterwards if this could potentially work.

So, I built a small business web page on sitebuilder.com, and they gave me a free domain (lassis-ec.com) and this domain works perfectly, but on the other hand i bought the domain I want to use, (lassis.com.ec), attached it to the site in sitebuilder and published the page, and it loads perfectly well in Chrome and Internet Explorer, but when I want to load the page in Firefox it won´t load, and the message that shows is as follows:

Corrupted Content Error

The site at http://lassis.com.ec/ has experienced a network protocol violation that cannot be repaired.

The page you are trying to view cannot be shown because an error in the data transmission was detected.

   Please contact the website owners to inform them of this problem.

Can someone please help me fixing this issue? Thanks a lot!

Dear all

On of the websites I have editors right on doesn't have SSL installed.

Since I upgraded to Firefox Quantum, when I go to the login page, I can't enter my login details anymore. The field is not clickable. It works on other browsers.

Firefox does warn me that the website is insecure, but how can I go through anyway ?

I'm used to using Visual Studio 2015 so I'm used to using an IDE but I can't for the life of me able to type anything. Its like I'm just using a browser instead of using something I can develop web pages with (please don't ask if I'm familiar with VS2015, why don't I just keep using it? It's a sore subject with me.) I probably going to feel like a fool when you tell me how I can access the text editing function, but I can't do any editing. I'm typing this in the 32bit Firefox I've been using for years. instead of the Developer's Edition.

Firefox 39 not downloading files in one particular server

Hi. This is my first question here and a weird one too. So please bear with me.

My company has many individual servers, all running the same Java program with same environment. We have a download button to download some data. However, the download link "DOES NOT POINT DIRECTLY TO THE FILE LOCATION". Instead we take the request, process it, write the data to a file in server, then read that file to the requesting browser.

In ONE of our servers, after our firefox upgraded, we are experiencing the issue that the download is not happening anymore for versions >=39. Previous versions are able to download the file correctly. Same behavior is seen in IE-11.

What's more confusing is that other servers are behaving normally even with firefox 39 and beyond. Only with this one server I am getting this issue.

Based on FF39 changelogs, can this bug-fix have some role to play in the observed behavior ? "Fix incomplete downloads being marked as complete by detecting broken HTTP1.1 transfers"

Attached are 3 images: Image 1: When download clicked, received the popup immediately though expecting some delay because of data processing. This possibly indicates that FF39 is not receiving any data from the server.

Image 2: When FF39 is not able to download the file it gives the warning shown.

Image 3: Trying to re-download the file using download manager downloads the underlying XHTML file instead which is EXPECTED BEHAVIOR because download is not a direct link to the file as mentioned before.

PS: I understand I am not giving enough information because I don't know how to reproduce this issue. Any pointer in some direction is appreciated. Thank you for your time.

I created a program which adds a certificate to Firefox to communicate with a websocket at localhost. To use it with https, I had to add a certificate to certificate stores, including the one Firefox uses. To Firefox, the command used:

certutil.exe -d [cert8.db path] -A -t "TCu,Cuw,Tuw" -n [name] -i [crt path]

Friday I noticed that it stopped working. I add, no issue reported. I use -L, the certificate is there. I even looked at Tools > Options > Advanced > Certificates, and it is there. But Firefox keep saying it's not trustable. Already closed and opened the browser.

I saw there was a update 13th June. Does it changed something about certificates part?

Firefox doesn't randomly load webpages

Hi,

I use Firefox v590.0.2 (64 bits) with Windows 10.

I use Firefox at my work, only for browsing our intranet. I'm a web developer so I load many pages on our intranet. Since a few weeks, I noticed that the pages are not always loaded correctly: the page starts to be loaded, and then it stops and it's loading forever (with the "Waiting for XXX" message at the bottom left). If I refresh the page it will eventually load as expected.

I tried to install a new Firefox on *another* computer, and I use it to browse the same website. And the same behavior appears: it works very fast and well for some pages, and then randomly stops working for some random pages.

On my main computer I tried to create new profiles, delete everything, without success.

I also tried to deactivate the hardware acceleration on both Firefox, without success.

When I check the Network tab from the web developer bar, I can see that some CSS files (it's not always the same, and it can be 1 or several CSS files) are not loaded (see the attachment) and appears with a grey dot, just like if the browser was trying to load them but it cannot, blocking the page. (I've also noticed it could impact other resources, like, at least images)

Before v59 I've never seen this behavior.

Note :

 - our intranet is on Sharepoint, with NTLM auth
 - at home I use Firefox on my personal computer and it works normally (but I don't browser the work intranet)
 - at work, because it's on the intranet, the network doesn't go thru a proxy
 - I'm now using Chrome because of this issue with Firefox, and the problem doesn't occur in Chrome

Thanks for any help.

First off, thanks to everyone who pitches in to help resolve this headache. Sheesh!

Problem: The Header image and text do not display properly in Firefox: The content does displays properly in Chrome, Opera and Safari. By the way: I have read and attempted all the applicable troubleshooting suggestions Firefox has supplied without success.

Website: www.twoworlds.ca The page in question is www.twoworlds.ca/other-world.html

Note: I coded the site myself using largely a w3.css framework. Admittedly, the source code is messy. I'm still chimpin' around (experimenting) with things.

Incredibly, am unable to upload two 137 kb screen captures of the problem for visual reference - an endless spin wheel for 12-minutes. Wha..? In that case, please visit my site in Chrome and then Firefox to see the difference. the site again: www.twoworlds.ca/other-world.html

We have an Add-On that will no longer work with FireFox once it updates version 60.2. It will heavily impact our stores ability to use certain functions/integration with our website until we get either a new add-on released or make a change to the site. We had planned on disabling updates for FireFox temporarily on each PC at each store but I am hoping for a workaround. I am curious if there is a list somewhere of the server IP’s/URLs that FireFox would use to update. This way I can just blacklist those IP’s for the time being until we get a new add-on released or an update to our website. This way they would not be able to download the latest update. It would prevent me from having to alter settings on each PC at each store (we have close to 70 locations and 4 computers at each). Is there such a list? And if so can someone point me there? Thanks!

I am attempting to create a customized installation package for Mozilla Firefox v40.0.3.


>> OS : Windows 7 SP1 x64 <<----

I have performed a Custom installation of the browser (unchecked 'Install Maintenance Service' check-box).

After successful installation, copied the following files to the respective directories:

1. Copied 'local-settings.js' to 'C:\Program Files (x86)\Mozilla Firefox\defaults\pref'


Contents of this file-----------

pref("general.config.obscure_value", 0); pref("general.config.filename", "mozilla.cfg");



2. Copied 'mozilla.cfg' to 'C:\Program Files (x86)\Mozilla Firefox'


Contents of this file-----------

// pref("browser.startup.homepage", http://intranet/); pref("browser.shell.checkDefaultBrowser", false); pref("app.update.auto", false); pref("app.update.enabled", false); pref("app.update.service.enabled", false); pref("browser.cache.disk.smart_size.use_old_max", false); pref("browser.search.update", false); pref("datareporting.healthreport.uploadEnabled", false); pref("signon.rememberSignons", false);


After performing these steps, when I attempt to launch firefox, it fails to launch at all. No errors are displayed. In Task manager, I noticed firefox.exe getting invoked but it exits within seconds.

What is the cause? Please help.
