Firefox Support Forum

I‘m somewhat uncertain: I downloaded the Firefox Installer from (I believe) Mozilla.org via Edge. When I tried to Upload the file to VirusTotal I got errors first and it only worked after restarting the laptop.

The file hadn‘t been analyzed so far (which surprised me), 1 out of 72 scanners claimed to have found a Trojan but what bothered me more was that according to VirusTotal the file was compiled in 2018 with Microsoft Visual C/C++ 12.00.8168. It was also somewhat smaller than the last Installer I downloaded (342kb vs. 390kb), although both should be version 18.05.

So I‘m a little concerned if the downloaded file is legitimate?

Hi,

i want to autoupdate firefox silently on a bunch of servers. When the mentioned settings are in place i'm still promted to update firefox when opening it. This isn't possible for the users as this is something a systemengineer should do. Is there anything i'm missing for a silent autoupdate? There is no JSON file in place. these settings have been distributed by a GPO.

Kind regards,

Remco

Awhile back [the question was asked], however the 'solution' is not what we are after here.

Once upon a time, there was a table with the Firefox downloads. And in previous versions. That is what I am looking for. I do not care, repeat, do not care, about the form input selecting 'latest' platform, etc.

Assuming also there is a method of downloading offline installers using tools like wget.

Thank you...

Hello.

I have two profiles, for separating work and personal tabs/bookmarks/etc. I wanted to update Firefox from 95.0 to 95.0.1 but in both profiles I saw "Firefox is being updated by another instance" in the About Firefox dialog when both were running. So I closed one of them and the other offered me the usual button to update immediately. I did it, restarted that Firefox instance/profile, which restarted normally, but now the second one does not open. Instead, I get the error transcribed above in the subject (see attached screenshot).

So my question is: please, how do I regain access to my second profile without losing that profile's data?

After today's update to version 98 Firefox keeps saving files to the Downloads folder when I don't want it to, I just want to open them, but not keep them, with this new behaviour the Downloads folder keeps filing up with useless clutter.

For example, before the update, when I downloaded a .zip file, a pop-up would show up asking if I wanted to save the file or open it with an application. If I chose to save it it would be saved to the Downloads folder, and if I chose to open it nothing would be saved to the Downloads folder.

After the update, when I download a .zip file, Firefox always saves the file to the Downloads folder, even if I choose to open it.

Can you please tell me if there is a way to make Firefox behave like in the previous version?

Hello, since migrating from Chrome to Firefox, I have used the Import Wizard to successfully transfer over my bookmarks and history, but I just can't seem to get my logins/passwords over. The wizard finishes saying that it successfully imported saved logins and passwords, but nothing shows up in the password manager. I am running Windows 10 64bit and Firefox is up to date. Anybody have any suggestions?

Thanks

I am running El Capitan and need Firefox 78. I went to a site offering 78 as a download, and version 91.5 came down. Site offering 78esr, same thing. Went to https://ftp.mozilla.org/pub/firefox/releases/ and was unable to figure out how to download 78. Clicking on 78.0 just led to more links that got me nowhere. Is it possible to download version 78 from this or any site? Thank you. heaton5

My job requires me to download and open files in new tabs consistently. However, when I download these files, I don't want the download panel to obscure my vision. Can I disable it?

Hey all , i made backup via "export passwords" via password tab and i came back to my pc to and tried to import via csv file but when i pick my csv file nothing happens , any ideas ?

I've read all the articles here about importing my passwords and history, but the Import Wizard is ONLY giving me the option to import my bookmarks. Even if I can't get the browsing history I need to be able to migrate my (extensive) password list.

I've exported my Safari passwords as a .csv file, but there doesn't seem to be an option to import a .csv file.

The page here regarding it says the feature is 'disabled by default' but does not say it's unavailable and I can't find clear instructions for how to activate the feature so that I can import my passwords. Can anybody help?

Hi, I can't install Firefox and I don't know what's going on here.

Yesterday I installed the latest version of Firefox and it worked fine. Then, I turned off the laptop and the next day when I was going to use Firefox, it didn't load any pages. Edge was working fine, Chrome was working fine, but Firefox was not working. Trying to fix the problem, I decided to uninstall Firefox and installing it again. In order to clean even more the previous installation, I even manually deleted the C:\Program Files\Mozilla Firefox folder to remove all possible traces. I restarted the laptop and downloaded again the Firefox installer. I don't know how, but the installer detected that I had already installed Firefox before. I unchecked restart Firefox and hit the button to continue with the installation. After this, was impossible to install Firefox again. I got a message saying that the installation cannot continue because the VCRUNTIME140_1.dll was not found. The message said that this problem can be fixed by reinstalling the program, but that is not true, everytime I try to reinstall it, I get again the VCRUNTIME140_1.dll error.

After this, the installation stops and the Firefox icon appears on the desktop, but it doesn't install properly the software and when I open it, I cannot browse the Internet.

Do you know what's going on here and how to solve this?

Cheers

Anyone know if there is a way to import Google Chrome extensions into Firefox. I am moving over and want to make it easy. When I search all I get is bookmarks which I know how to do.

TIA!

Hi, new updates on Version 98.0.1 quite a hassle for me. It auto-download all my files even when I just want to view. Is there any other way to disable this feature? I opened Setting>Download but there is no disable button or checkbox for that. Please help me. Thank you in advance.

I have a Win7 machine, and just bought a new Win10 desktop. I followed some instructions from a YouTube solution. From the Help>Troubleshoot>Profile Folder, I copied the profile folder (onto an external drive) and pasted it (from the external drive) onto the new OS(C:) as per instructions.

It did not work, I do not have all my bookmarks and extensions, etc. on the new Firefox browser I have installed on my new machine.

I don't know what to do now. All that was selected and overwritten is still selected on "This PC>OS(C:)" I was tempted to just delete all that shows selected...maybe not a good idea.

I really just wanted to migrate all my bookmarks, but doing the full profile folder seemed like a good idea at the time.... Help Mr. Wizard?!!

I need to transfer saved logins from Firefox on a soon to be retired laptop to Firefox on a new laptop. New laptop has a few logins created while setting it up than I copied manually knowing that when I import from the old laptop with many logins, the few on the new laptop will be overwritten. My problem is that Firefox can export logins into a logins.csv file but it seems can only import from a Microsoft browser. Is copying the key4.db and logins.json from the old to the new the only correct way to do this? The old laptops logins.json file has a recent date but the key4.db has a 2018 date even though some new logins were saved last month. Do I only need to copy the logins.json file?

I would like to save my Firefox profile data into my computer as I would like to transfer the data to a different computer. Is there any solution to how to save it down?
