Firefox 技術支援討論區

Tried to download firefox browser. It just says in downloads 'Couldn't download - Virus scan failed'. How do I fix this? I did check that my laptop is updated. Security is updated. Scanned laptop for viruses, got nothing. Restarted laptop. No change.

Firefox used to give the option to open a file without saving. Now it saves everything to my downloads folder with no option to just open. (I am aware Firefox used to save the opened files in temp). This causes major clutter in my downloads folder and big disruptions to my work flow. Sometimes I just want to view the file and not save it to my working folder (downloads).

Is there a workaround to save to opened files in temp and the saved files to download?

Does Firefox give 2 different "save to" options? One option for a location to save downloaded files and one option for a location to save opened files?

Last year someone asked about 2 Firefox for Android applications; I just had two different copies of Firefox installed on my Win 10 laptop (one in an attempt by Microsoft to upgrade to Win 11) where all my data was in the old app named 'Mozilla Firefox') while the newly installed app was just 'Firefox' and had none of my data. I did not attempt that new install, it seems Microsoft did ?? They also mentioned wanting to redirect the new Firefox to specific Domain Name Service servers, rather than the traditional server addresses provided by the local network. Anyone know what's going on?

Firefox is just not working for me. It's not reading the stylesheets on my website, tabs are disappearing but the websites are still open. It seems the installation may have become corrupt. If I uninstall and reinstall what data will I lose if any?

I am looking for suggestions/work flows for migrating existing Mac's from the standard firefox release to the ESR version. I am looking to manage these all under 1 update cycle. A couple of current problems:

1. On a system with the standard version already installed, I can't find a way to upgrade to the ESR version without uninstalling first.
2. Once I would do an uninstall and then an install of the new version, I am prompted that I have launched an older version of Firefox and that I must create a new profile. How can I do this without loosing all users bookmarks, extensions, etc?

Thanks!

Hi

  Is there anyway to stop firefox downloading files entirely?  Or at the very least, stop it auto downloading or prompting to save download settings ?

thanks,

I have two identical computers running Firefox on Windows 7. No serious issues for 3 years or longer.

Just recently, version 100 showed "Unknown Source" instead of the normal UAC authorization window which lists mozilla.org as the source.

The 100.0.1 update showed the same warning.

This only occurred on one of the computers. The other one does not show the warning.

Firefox worked fine after doing the downloads anyway, but the "Unknown Source" is not right and makes the user think security is being compromised.

Each time Firefox is refreshed, I must re-install extensions. How can I save the extensions so they do not need to be downloaded and re-installed ever time Firefox refreshes?

I use to click on PDF files and they would open and not download to my download folder. Well now every time i click on a PDF file it downloads it. I have tried every option in settings/general/apps and they still download in a folder. So I thought I would try MS edge and it does the same thing. Is it not the browser and was it in a MS update? It has never done this before. I don't want all these PDF files downloaded!

Hi,

I looking to get Firefox to open up a PDF in the browser WITHOUT downloading the file. The reason for this is because I want to bookmark the PDF allowing access to an up-to-date version of a document.

I have selected the option to ask where to the save file in the settings. I have also set the application settings for PDF to 'always ask'. So, when I open the link, I get a window prompt asking me to select 1 of 3 options: view in Firefox, view in selected application, or save. I select view in Firefox and it still downloads and opens the file.

I definitely know Firefox used to open up PDFs AS links because I have some bookmarked. Any suggestions on why this is and how to fix would be greatly appreciated.

Thanks in advance.

I've been seeing suspicious .htm files appear in "downloads" when I hadn't requested any downloads. When I try to open the file, it always appears blank. Once I rebooted without deleting the file, and my system acted like it had a virus. I rebooted in Safe Mode and reverted to a restore point, then everything was fine. But I'm still seeing those suspicious files appearing, at least once per day. How do I stop them?

Can’t find how to sign into uBlock because I keep getting request to download Firefox even though I have used Firefox for years. I can’t find a button to push to complete the sign into uBlock extension

right and left clicking on the open app menu in the far right column didn't help me. I'm only a 17-year computer professional with a Ph.D. who publishes in peer-reviewed journals. How am I supposed to guess what to do?

Will it be OK to upgrade my Firefox browser from Rel 72 to latest Rel 100 in one step ? OS is Mac OS X Monterrey 12.3..1 Or should I do 1 or more intermediate upgrades to be safe ?

FWIW, I've had enough problems upgrading from OSx Mojave to Monterrey. I am leery of the huge jump from FF 72 to 100.

All advice most welcome.

I would like to know how I can un-install Pocket from my windows 10. If it isn't possible, I would like to know how I can delete my account of Pocket that I had created. Thank you.
