Server Error in '/' Application (only in Firefox) - asp.net

I have a bit of a brain teaser. I am getting the attached server error when I load ANY page on my website. However, this ONLY happens in Firefox. Any other browser loads the page just fine. I have cleared my cache and have completely uninstalled and re-installed FireFox to no avail. Any idea why a server error would only show up in certain browsers? This is a windows based machine running IIS. I'm totally stumped. Thanks!

It's hard to see the exception type because the text is so small on you resized image.
Have you tried monitoring the request using Fiddler, or launching FF Dev tools (CTRL+SHIFT+I from FireFox)? Is there anything in that output that could reveal a clue?

Chrome waiting for available sockets, Firefox is fine

We have a Wordpress based website (rendeljkinait.hu), and we face freezing issues while editing articles when using Chrome. When I hit the save button for the 7th time without page reload, the article editor freezes during save and I get "waiting for available socket" error in Chrome. No matter how long I wait, the editor won't save until I reload the page. When I'm using Firefox, everything is fine, no matter how much I hit the save button. Current Wordpress version is 5.2.3, but error occured in former versions too.
I investigated the error, and found it is caused because Chrome never closes the open sockets until I reload the page. So until hitting the button 6 times everything is fine, since Chrome and other modern browsers allow to have maximum 6 paralell connection to a single host. But after I press the button for the 7th time, there is no space for another connection, so Chrome is waiting for the older connections to get closed, but it never happens.
Here's a screenshot from net log
Using Firefox I observed that it always closes the connection after the save is successful, so only 1 connection is active all the time, it never exceeds the 6 paralell connection limit. I attached Chrome netlog file here, you can view it here. I also attached a video showing Firefox closing the connection here (107.6.*.** is our servers IP).
For various reasons we have to use Chrome, so I would like to find a solution for this problem, but I'm completely stuck. Does anyone have a suggestion what could cause the problem and how to solve it?
Thanks in advance!
I have the same problems with chrome and gutenberg.
It is impossible to do any heavy editing on the site, so I use firefox for all admin related stuff.
Haven't found a solution either...
For anyone who might find this topic with similar problem: seems like it was a Wordpress bug, a Wordpress update solved the issue.

Troubleshoot ASP.net WebForms download file problem

In my webpage, I have a download button will write excel to response and it work previously. But I got a problem today that browser on client (tested IE and Chrome) cannot download exported excel from ASP.net webforms suddenly without changing code and software install.
When I test in Chrome, console show that Resource interpreted as Document but transferred with MIME type application/vnd.openxmlformats-officedocument.spreadsheetml.sheet.
I used the notepad to open the downloaded excel and the content become the my web html page.
I tried to login server and use the browser in server, the file can be download normally with correct content.
I have tried to copy the web folder to another server and iis setup, it show same behavior that the downloaded excel become html content of my page on client browser but work in server browser.
May I have any idea how to troubleshoot on this case please?
Thanks
Are you facing this issue on a domain/managed network? If yes, are you the administrator of the network? If that's not the case, please give these suggestions a try:
If you’re using an antivirus or firewall software, make sure Chrome
is trusted or allowed by these programs. You can also try
temporarily disabling your antivirus or firewall to see if this
resolves the issue.
Just to make sure we eliminate malware from the
scenario, please follow the steps from this help article.
Try resetting the Chrome browser to see if that helps.
Also, creating a new user profile on your Chrome can be helpful.
If the issue persists, download and run Chrome Canary. It is the
cutting edge developer version of Chrome that can be installed
alongside Stable Chrome. It's possible the problem won't exist on a
future version.

Chrome give error **Failed to load resource: net::ERR_NAME_NOT_RESOLVED** while other browser load images

When I open my site in Google Chrome, it gives the error failed to load resource in the console. My images are not showing in Chrome but are fine on other browsers. How can I fix this issue?
I had the same issue. I'm working on Windows 8.1 system and had the problem with almost every page in Google Chrome, IE 11 and Firefox.
This is what worked for me. Run CMD as administrator and execute the following commands:
ipconfig /flushdns
ipconfig /renew
ipconfig /registerdns
I did not have to restart my PC, but everything worked again and all pages on the internet were avalible again.
As a quick test to see if that's your problem, start Chrome in incognito mode with extensions disabled (ctrl+shift+n) and see if your page works now. Note that by default all extensions will be already disabled in incognito mode unless you've specifically set them to run (via chrome://extensions). please refer to this
I've spent weeks fighting with this problem on 2 different unrelated computers, even unable to ping Yahoo.com and having variety of connectivity issues in web browsers, including "DNS_PROBE_FINISHED_NXDOMAIN" and "ERR_NAME_NOT_RESOLVED". I've tried various ipconfig commands, restarting DNS client service, "netsh winsock reset", and other solutions found on the internet.
Finally I realized the only common thing on both my computers was Malwarebytes. After closing/exiting Malwarebytes the problem was solved. I am now able to ping and access every website. The solution, again, at least in my case: close Malwarebytes
I just contacted Malwarebytes support but in the meantime wanted to provide this possible solution here.
You might have to check your internet connection. Many a time, the data can't be fetched due to bad or no internet. Or open the site in incognito mode and check whether that works or not. If you are using any blocker extensions, disable and check again.
You can do that via (chrome://extensions).
This can be caused if the URL supplied is wrong, this was my case.

"The connection was reset" in Firefox only on postbacks

I'm getting an error message of "The connection was reset" in Firefox on my ASP.NET site. Here are the details:
doesn't work in Firefox 11, 12, and 14 though appears to 3.6
happens everywhere on site where there's a postback
the message comes up in under a second after doing the POST
works in Chrome and IE
works locally
view state is relatively small
the pages are not performing long operations (e.g., file upload)
I've tried clearing the cache and running Firefox in safe mode, but it makes no difference.
Any help would be greatly appreciated!
Close all of your anti-virus software and restart your FF.

Wordpress site under windows XP - appears to be many problems

Would someone mind looking at this fairly basic (I thought) site that I've built for my father?
www.pws-consulting.com
It loads up fine and works under the latest version of chrome, firefox, safari on my mac, and does the same on windows 7, even in ie. (though some of the css dies, which is acceptable).
On his windows xp machine however, the site has many problems.
Explorer browser.
Upon initially accessing the website, the following error message appears "Internet Explorer encountered a problem and needs to close".
When I hit "Don't send" for the error report, the tab for the website is recovered and it reopens. Pics and text content look ok.
However for every hyperlink (Services, Contact, etc), the same error message above appears.
Eventually the browser crashes.
Firefox browser:
Website opens normally but all text content is mispositioned at the bottom of each page, hyperlinks repeat, colour map does not appear, etc.
All-in-all, a formatting mess.
I've used AdobeBrowser Lab to test the site and it appears to be finder going back to IE 7, Firefox 5.0 on windows so I'm at a lose to understand what is wrong.
Thanks in advance for any help. All the best to everyone in this new year.

Doesn't seem to crash on WinXP IE 6.0 for me. Works great on IE 7+ though. No problems in Firefox, Chrome, Opera, Safari either. Must be an issue with your computer? Did you try another computer?
