Firefox Support Forum

I noticed that FireFox downloaded a Firefox HTML Document called GnT6qZGD with a size of 0KB, during this time I had tabs open from both https://wago.io/weakauras and https://www.curseforge.com/

Scanned it with Bitdefender and it was clean and when editing in notepad it is empty and a blank page when accidentally opening it.

Then completed a full system scan and it come up as clean.

I have 2 questions,

1st, Is this still a bug in Firefox that appears to have been reported before? 2nd Should I be concerned about it?

Thank you

I've been having problems with some websites not displaying content, others displaying error messages. So have been going through the Troubleshooting Mode and diagnostic process.

The cause is the MS CoPilot extension for Firefox.

Useful in other ways as I discovered several other extensions I don't need, hence have remained disabled.

This has been happening for about a year now, I followed the guide and tried the troubleshoot mode and my tabs still crashes.

Can anyone help me read the crash reports and find the cause or common issue?

Here are the most recent crash reports I submitted.

I am unable to get printing to work correctly using Firefox with Epson POS TM-T20 thermal printers we have a work.

We're currently running Firefox on Debian 12. I've tried both the ESR version that comes with the Debian repository and the latest Firefox as a flatpak.

When printing to the receipt printer, the only thing that is printed is the left-hand most part of the logo and a little part of the text and this occurs towards the right-hand side of the paper. I've changing all of the settings, resetting the settings for the print in about:config, but nothing seems to work.

I'd love to get this working so that staff could use Firefox. I'm attaching an image of what the print job looks like and a screenshot of what the print-preview shows.

Several instances of this "verification.exe" malware appear on download history when firefox is opened as shown. Remove from history or clear downloads doesn't eliminate them. They reappear whenever firefox is opened.

Suggestions to eliminate this nuisance welcome.

I've made an extention which works fine when I test it using the temp mode on firefox. When I attempt to install from file however I'm told it could not be installed as it appears to be corrupt. Below are the package.json and the manifest.json:

package.json

{

 "name": "ext",
 "version": "1.0.0",
 "description": "",
 "main": "contentScript.js",
 "scripts": {
   "test": "echo \"Error: no test specified\" && exit 1"
 },
 "keywords": [],
 "author": "",
 "license": "ISC"

}

manifest.json

{

 "manifest_version": 2,
 "name": "SKUORG",
 "version": "1.0",
 "description": "Organises SKUs on WooPage",
 "permissions": [
   "activeTab",
   "webNavigation",
   "<all_urls>"
 ],
 "content_scripts": [
   {
     "matches": ["<all_urls>"],
     "js": ["contentScript.js"]
   }
 ]

}

I have tried on two devices / installs of firefox and have followed the steps I could find on this page : https://support.mozilla.org/en-US/kb/unable-install-add-ons-extensions-or-themes#w_corrupt-extension-files

If you have any suggestions please let me know.

I am running the latest updates to Windows 10 Pro x64. One of my monthly bills is paid at

1) https://e.synchronyfinancial.com/

which, in Brave, redirects to

2) https://lowes.syf.com/accounts/login

Inputting either link in Brave gets me to the finish line but the first link above fails in Firefox with the "Secure Connection Failed" message and dumps me at https://www.synchrony.com/accounts/. The second link does the same.

Is there any way to troubleshoot the problem?

I HAVE tried shutting-down Malwarebytes but the result was the same.

This is the only site on which I have encountered this issue. All that I can determine at the moment is that that certificate is from DigiCert and the expiration date is in 2025, i.e., this is not a Symantec cert.

I don't use Google Chrome browser nor do I use MS Edge. After using the Mosaic browser, I switched to Netscape Navigator, then to Mozilla, and, finally to Firefox. I am not looking forward to migrating to another browser. ;-)

So I have an Excel workbook in my onedrive from MS, It was working fine on my firefox browser in my Ubuntu OS, last week it started to delete my cell's information whenever I pressed the enter, tab or arrow keys, I contacted the MS support and they get me to opened the same file on a chrome browser and worked fine... I still want to use my firefox browser but this problem is very annoying, please help me sort it out!!!

I'm using Firefox 124.0.2 (64 bit) on Windows, and every few days I get the error about using an older version of Firefox, with Exit or Create New Profile options. I then run "firefox -allow-downgrade" from the command prompt and everything works fine... for a few days, when it happens all over again. This only started happening a couple of weeks ago, but it's getting really annoying. How do I stop it (short of using something like Waterfox or Brave).

So I'm having issues playing 4K videos fully on one YouTube channel: https://www.youtube.com/@ClearviewDriving

For some reason anything above 1080p gives me bad stuttering but on other channels videos don't stutter or freeze when playing 1440p or 4K quality.

Firefox is updated, I don't use Extensions other than Ad Blocker and I have that off on YouTube anyway. Seems strange that it'd only affect one specific channel.

I have a very good gaming PC too so the hardware isn't the issue.
