Hello,

I’m encountering an HTTP 500 Internal Server Error on a custom web application that I’ve been developing. The error occurs intermittently and is not tied to any specific action or user input. I’ve checked the server logs and they show generic error messages without much detail.

Here’s what I’ve tried so far:

Checked server resource utilization and logs Reviewed application code for potential issues Verified database connections and configurations Despite these efforts, the issue persists. I’m looking for advanced troubleshooting tips or any specific tools that can help diagnose and resolve this issue. Screenshots and log excerpts are attached for further context.

Any insights or recommendations would be greatly appreciated!

Thanks in advance.

Firefox 129.0 (64bit) - Windows 10 (with current updates)

Sometimes (except when I'm demonstrating the problem of course) a Google search simply hangs. In the search field (next to the shield & lock) the website for the search appears, eg https://www.google.com/search?client=firefox-b-d&q=how+secure+are+android+phones or https://www.google.com/search?client=firefox-b-d&q=nsw+service+parking+meter+app there is no other response and no activity in bottom left corner of the window.

Simply clearing history (history, cookies, cached files, but not site settings) fixes the problem and the search can then be repeated and new searches done until the next time, when it's a case of rinse & repeat. No other action is required, which would seem to suggest that the problem isn't elsewhere.

This problem affects both my wife's and my PC (same configs), and has for several weeks, sorry can't be more precise as to when it started.

Thanks, Mike

I am constantly seeing this message on YouTube. I don't have troubles with any other website. I get this message yet other tabs will happily load different pages. I have a fibre connection, I am definitely connected! I have tried everything I can find to remedy this problem but nothing works, for example a flush DNS command. And yes, of course it absolutely still happens in troubleshoot mode.

This has been happening for over a year now and it is absolutely driving me insane. Whenever this happens I can open another browser and will have none of these problems with that browser. I have been using Firefox for over 20 years religiously, but I am getting so sick of this that if I don't find a solution for this problem soon I will be done with Firefox, I don't even know why I've persisted with this problem for so long. Please help!!!

I'm encountering a problem with my website on Mozilla Firefox. Although the website speed is excellent, it doesn't load properly—layouts are broken, and images/stylesheets often fail to appear. The site works perfectly on Chrome, Safari, and Edge.

Details: Website URL: https://coralheartcounseling.com/ Steps Taken:

• Cleared cache and cookies
• Disabled all extensions
• Tested in Private Browsing mode
• Checked site code and server logs
• Any advice to resolve this issue would be greatly appreciated.

This is a persistent issue for many a version. I've tried these config settings too and it still consistently-inconsistent resets it sometimes. app.update.auto (->false) app.update.auto.migrated (->false) app.update.enabled (->false) app.update.service.enabled (->false) DisableAppUpdate (->true)

It does this on closing hanging browser or on system power off (without closing browser manually). Also if setting is set to don't update -> close browser within a minute -> when reopened it is on autoupdate again.

My searches (regardless of Engine) are coming up in Russian. I don't speak Russian. It does not seem to be the search engine, and does not happen in Chrome, only Firefox.

Recently, as in the last two days, when I am in the process of filling in forms online, Firefox auto-fill offers me the choice of my phone number and a phone number that is unknown to me. I am 100% certain that I never erroneously entered this second number when filling in a previous form. The number bears no resemblance to my own. How the number came to be in Firefox auto-fill is a mystery to me. I used Canada 411 reverse look-up to check the number and discovered that it is a valid phone number belonging to a person I do not know and have never had any contact with. My question, then, is how did his phone number end up in Firefox on my computer? Is it possible I have been hacked?

I cannot connect to Amazon site, says unusual payment activity, secure connection failed, and the name Stanford Health Care, that I have never heard of and have no connection to them. I need to have this corrected. Please reply. Rosalie Koire, roko8@att.net.

There are 48 responses to Sync between laptops, but nothing happens when I click replies.

My connected devices shows one of my Windows 11 laptops, but not the other, and it still shows the Windows 10 desktop which I replaced.

How do I add my  2nd Windows 11 laptop to the device list and then sync everything from the first laptop to the second?

After I've had a window open for between 5 minutes and half an hour, the address bar stops working. I need to open a new window in order for it to work again. I can click on the favorites on the homepage and those work but if I search or input an address into the address bar nothing happens.

Hello,

My microphone has recently stopped working on Firefox, and Firefox only.

It works in Chrome, Edge, and Opera.

I have tried reinstalling Firefox (and testing the mic with a clean install), reinstalling all of my audio drivers, and even changing the frequency of my Windows sound to a lower one. Nothing has worked.

My laptop is a Lenovo Slim Pro 9i (if it matters) and my microphone is an Intel Smart Array.

I have completely run out of ideas, so anything will help at this point.

I can't get any app from Google to stay open. It's a nightmare. I've restarted several times. Doesn't help. Everyother page is working.

Is this a bug in the latest version?

I get this same message. The page flashes on then crashes and this message appears.

Is it still possible to sing into Lockwise on my iPhone? Have attempted using two different Firefox accounts without a completed connection. After entering password the Get Started page returns asking for login

For a number of months, I have not been able to update firefox to my Linux system. I download it and opened the downloaded file, opened various files, but nothing happens. I have tried using various methods to download and update it, but I continue to get a message that update is available. I'm currently using 121.0.1. I have a number of download files in my download folder, such as..."/home/jim/Downloads/firefox-128.0(1).tar.bz2" I tried to uninstall and reinstall "How to remove Mozilla Firefox from Ubuntu"

   sudo apt remove firefox.
   sudo rm -Rf /usr/bin/firefox.
   sudo rm -Rf /usr/loca/firefox.
   sudo snap remove firefox.

and then this "Install Firefox" First, add the Mozilla signing key $ sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 6DCF7707EBC211F. And then install the latest version of Firefox with this command: $ sudo apt install firefox. These commands seem to complete normally, but I continue to get "update available" messages. I give up. I've done everything I can think of. Help would be greatly appreaciated. Jim
