Dear all,

We develop a system on D365 platform. On Chrome enviroment, I click the export option, it will download the excel file, I can open it on Excel. However, I click the export option on FireFox, it will download the excel file but I can't open it on Excel. When I use the notepad to open the file to see the content, I found the file become HTML content. I can see the file on web broswer. I don't know why the file content will be change HTML content when I use the Firefox to download it.

Please help....

For the past week, my browser does not auto-update. I have to download the update and re-download the browser.

I went into the settings and found the update section and when I clicked "Check for Updates", it kept saying "failed to check for updates". I tried with my proxy-settings on with VPN on, proxy-settings on with VPN off, proxy-settings off with VPN on, proxy-settings on, with VPN off.

This is in my personal laptop, where I am the only and admin profile.

My Firefox used to to auto-update but now it keeps saying I need to download the update, but my browser can't even tell if I have the most current version or not.

Prior to update 125.0.1 corporate intranet users could download PDF files from our Line of Business applications / Webpages. Today after the latest update the PDF files download but are corrupted. The site was added to the trusted webpage without improvement.

Adobe Acrobat Reader could not open ********.pdf because it is either not a supported file or because the file has been damaged

Recently Firefox always has the error "failed to check for update". I have tried restarting my pc and running as admin. I am on windows 10.

I have been able to manually install the latest version by installing it over the top of my current install, how can I fix the error to be sure that my browser will auto update?

Thanks

Hello,

When I go to update Firefox through the settings > general > firefox updates > check for updates, I am getting the error in the title. I can manually download the app installer and update to the most current version which is what I did for version 125.0.1, yesterday.

I have tried uninstalling and reinstalling firefox, installing the beta branch, refreshing firefox, running in troubleshooting mode, completely deleting all user firefox files, and I still get the error. No DNS resolver issues to the update server. No firewall issues. No network blocking (tested with other devices).

This issue started after March update to 124.0.1 and continues to current stable release 125.0.1.

This issue also seems to extend to checking for extension updates.

Below are browser logs for when i try to check for update or update extensions.

Not sure if this is a new 'feature' post-update but it's damn annoying. I was busily transferring some photos that I'd taken on my phone over to Firefox on my Mac. Wasn't until I went to find them on the Mac where they would normally be and couldn't find them. Bit of digging, opening up the Download 'history' on Firefox and saw "File not downloaded: possible security risk".

I can see that I can disable this 'feature' but it seems to be a global "allow". Is there any way I can tell Firefox to allow any downloads from my devices on my network yet warn for potentially insecure downloads from the web?

TIA

Hello,

In the past, FF downloaded documents without opening them in the browser. This is two weeks now that whenever I download a document, FF is now opening the document in the browser without asking me.

I welcome if someone could tell me what I can do to stop FF from opening the documents.

Thanks for any help you can offer me.

Greetings,

When I started getting msgs saying my browser was no longer supported, I checked my version. Firefox says i have v115esr and that it is "up to date" - i.e. no update available at this time. I assumed I was getting the brush off from those web sites.

Why did Firefox not bring me up to v124? I get a "download update" probably once a month. It's been giving me a new variation of 115esr all along.

I've now downloaded 124 from your site. What do I need to do so that I stay current in the future? Thanks John

I am not sure when exactly problem started but for few months I have problem with automatic update of firefox. It properly detects update and downloads it but when I click to restart browser and apply update (this should close browser and display update install bar) nothing happens - browser simply closes. When I launch it again and go into "about firefox" again I see spinning circle next to "installing update". Of course this update never installs. When I close it for 2nd time and go into "about firefox" it goes back to "update ready to install, click to restart" - and again, when I click it browser simply closes without restarting and installing update. I tried removing my profile, using safe mode, disabling antivirus. Issue seems to be related to firefox itself. I also tried removing mozilla maintenance service but it did not help. Does anyone have any idea what could be causing this? For now only way for me to update firefox is manually download full installer from website and then it installs latest version without any problems - until next month comes and I have to update it again.

I cannot get firefox to update. It is set up for automatic updates but they don't happen. Even if I try manual installation of updates it says the update fails. I ran it in troubleshooting mode and the problem still exists. I restarted my computer and the problem still exists. I am using a mac running on Monterey. How can I get it to auto update again? (and even though it says failed to check for or install updates, it looks like I do have the latest version of firefox)

I need help with everything to do with email so what is your email address or what is your phone number so I can ask my questions ?

I have migrated from old MacPro to new Mac Studio. Firefox ESR version 115.9 has migrated with it. I've downloaded the latest Firefox but it operates independently of the ESR version. How do I ensure new version has all log in, contacts and history?

On Mac OS 14.4 Firefox hangs on launch and crashes, requiring "Force Quit" when I try to Refresh or Troubleshoot. Uninstalled and reinstalled multiple times, and restarted computer several times. Have spent several hours trying multiple community suggestions to now avail.

I am not a programmer, but am able to follow instructions. I clearly need someone to hold my hand and walk me through the solution. (I even checked out the Kaspersky suggestion, but cannot install it because Firefox cannot connect to the Internet.)

I have downloaded and saved "Raw Data.docx" and "Application Basics tex.docx" from one of the crash reports.

P.S. On this question form Firefox guessed that my operation system was Mac OS x 10_15_7, but it is 14.4

A few weeks ago I saw an Mozilla ad for a new Mozilla software product that cleaned up your PC and made it run better. The price was around $125.00 (I don't remember that exact price). It said that I would receive an email from Mozilla with download instructions. it's been a few weeks and I have not gotten any email. Does anyone know if Mozilla offers any such software or did I get scammed? I'm pretty good about seeing scams but Ive used Firefox and Mozilla for years and trust them. Maybe that's why I wasn't as careful as I should have been.

Thanks for any help that you can provide. Ron

Hello!

I'm writing because I cant seem to import my old profile using this [tutorial]. I have followed it thoroughly, and every time I open firefox its still the same default page that you get when u first download the browser.

I have a System 76 laptop running Ubuntu 14.04 LTS. The LTS (Long Term Support) ended years ago with Firefox 66. All of that works fine still. My problem is: 1. The world is telling me to upgrade my browser. 2. Mozilla tells me "Note: If you use your Linux distribution's packaged version of Firefox, you will need to wait for an updated package to be released to its package repository. This article only applies if you installed Firefox manually (without using your distribution's package manager)." 3. There will never be an updated package because LTS has ended. 4. IS THERE A WAY TO MANUALLY INSTALL A NEWER BROWSER LIKE FIREFOX 123?
