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

Hi! On the latest version Mozilla Firefox 125.0.1 when i download .docx files i get the message 'File not downloaded: Potential security risk.' I select Allow download and the file downloaded can't be opened.

Thanks!

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 recently migrated data from my old MacBook Pro to a new MacBook Air. I installed Firefox on my new computer as it did not migrate. It installed fine but will not launch. Please help.

Hello,

James here. I CAN NOT find the Firefox application file location. There is no option to show file path upon right click of the desktop icon and I can not locate it in File Explorer. I have done an entire (C:) drive search and turned up nothing. C:\Users\(username)\AppData\Local\Mozilla Firefox does not exist in my file system. I am at a loss here and it's driving me bonkers!

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

The Debian Firefox packages available are only 115.6. Thought it would be nice to have the latest. Grabbed all the dependencies according to the Mozilla web site.

Installed Firefox 121.0 as root and placed folder into /opt, as instructed. Went through all the settings and imported my bookmarks.

Now there is a 121.0.1 upgrade available but my browser won't automagically install the upgrade. Says click here to download. So I do. I get the entire tar.bz2 bundle, which creates a full directory structure, as if I was starting over.

Can I just move a few files from that into the existing /opt/firefox directory to get the upgrade? If so, which ones?

Or, can I move few files from the existing directory into the new version, and replace the whole lot? If so, which ones?

Thanks in advance.

Can somebody give me a version of firefox for my windows 7 professional (64 bit os) that actually work. I literally downloaded many versions of firefox (esr ones,normal ones) with exe and msi installers. But everyone one of then never works,sometimes it doesn't even install or sometimes it installs but gives error , sometimes it says we're sorry , sometimes it installs but doesn't open nor does it gave any error window. Im getting a headache.Please somebody help me (╥﹏╥)

firefox setup 127.0.2.exe offline installer fails with message about "extraction failed" and popup "file is corrupt".

Windows explorer shows file properties and a signature for mozilla.

Is there a way to manually unpack the .exe? Someplace that issues are logged with more data (which file is corrupt?) There is a progress bar that flashes by part way, then a popup window with the file corrupt message.

(Trying to update to hopefully get rid of some crashes.)

Is there a hash for that .exe I could check?

Firefox automatically updated itself to version 126.0 (64-bit) and it was unable to display any web sites.

First I disabled Mozilla VPN but that did not fix my issue. Next, I disabled Microsoft Defender firewall software to no effect.

Finally I updated the shortcut to Firefox on my taskbar to launch the browser. This fixed my issue.

Hopefully, this will save other users from the same pain.

I tried to download a file and got an error that said "exceeded the maximum number of connections to this server" so I researched it and it told me to type about:Config in the address bad and I would get a configuration page that said "Advanced Preferences". I didn't get that page, I only got a page with a long list of things I didn't understand but I found "http.max-persistent-connections-per-server" and I changed that from 6 to 15. Will that help? I've never ever had problems downloading files or multiple files before. What else should I do so I don't run into this problem anymore? I didn't see anything in Firefox Settings that would help configure the settings.

I have two desktop icons for Firefox. Each opens to a different file. How do I clear the old file? What do I do about the message that Firefox can not update automatically? Where do I look to see Firefox file and see what date it is downloaded? If it is operational? Why is the same series of problems repeating daily?

Hello, please is there any chance to add Firefox download for Linux and aarch64 platform to the download list? The attached image shows that you currently offer a binary package for the aarch64 platform only for Windows. Thank you.

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.

Files will not download. The file is a rfa(revit) file. This is my second day using this web browser..

I have checked setting, to which I switched around to try and troubleshoot. This did not work. I ended up downloading another browser and the file downloaded no issue. Why is this happening? Ant help is greatly appreciated!
