Firefox 技術支援討論區

About a week ago I started getting these update error messages stating "Update available - Firefox couldn't update automatically. Download the new version". I've also tried clicking "Learn more" on the error message but it's a dead link. Going into the settings for updates I am set to auto update, but when I manually check for updates it says "Failed to check for updates".

The help article on this issue simply tells you to download and manually reinstall Firefox, but I'm having to do this nearly every day. I work in IT myself so I know a "bandaid" workaround when I see one. Is there a solution to this issue?

All of the files I try to download fail immediately. Even extensions will not download on firefox. I have uninstalled and reinstalled and checked the download location. Downloads work on other browsers such as Chrome fine but nothing will download on Firefox.

Really want to get rid of Edge and start using Firefox. However the last two times I downloaded and installed it looked like I had a huge number of trackers. I run Glarys Utilities regularly and this is where I found trackers. I do I install Firefox and protect myself from trackers.

Hello

since version 119 of Firefox a download behaves siometimes different. The directory and "Ask before save" are still valid. But sometimes Firefox start to save in the directory without asking. Why behaves version 119 sometimes different in comparison with previous versions like 118?

Kind regards

I found that Firefox can automatically generate a QR code for each URL, which is a powerful and useful feature! I'd like to know if this QR code has an expiration date.

Hi!

I want to uninistall my firefox application, but unfortunately the folder in C:/Users/XXX/AppData/Local/Mozialla Firefox/ is empty, so I cannot uninstall it. I tried downloading again and then uninstalling, but did not help. Can I manually add the .../uninstall/helper.exe in order to completely remove the application from my Windows Computer?

I takes up a lot of space on my memory disk, so I want to remove it, but can't.

Thanks a lot in advance

Good Evening, My company requested a factory restart and I compiled. I am working to restoring my old firefox bookmarks and preferably history/settings. Is there a way to find and restore this data? I am using the same firefox account as before the reset. Thank you.

Also, what are the best practices for backing up my data in the future to easily restore or transfer my settings and bookmarks in the future?

Only with Firefox (default) and Norton 360 My Norton page, the page does not recognize that the Password Manager is already set up and active. The Password Manager button erroneously shows "Set Up", and when pressed the surrounding oval turns blue and nothing else happens - forever! That button should say "Access Vault". Also, he Feature Setup incorrectly shows Password Manager as not being setup when it already is on, active, and functioning in other areas of Norton 360, and surprisingly through the Firefox browser extension NPM button. This apparent MY Norton syncing problem only happens with Firefox, not when using Edge or Chrome.

Sometimes, firefox will download the same file twice (or more) when I still have it.

I do NOT want to turn off automatic downloading.

I am asking, how to make firefox check if the file already exists before downloading.

I understand that sometimes you willl download multiple files from a website, but, even though they are all called "image.jpg" they are all in fact different pictures.

So, I think the solution to this is, when downloading a file, firefox should check if the file already exists.

If it does exist, start the download for file(1) as usual, but ask the user

"A file with this name already exists, are you sure you want to download it again ?"

And the choices should be

Yes (download continues) yes, and do not ask again for this filename (download continues) No (download is interrupted and partial file is deleted)

My current install of Firefox seems to be corrupted, because every time i try starting firefox, even in safe mode, it says "Could not load XPCOM". So my only option now is to reinstall, but i have some password and my search history and bookmarks and generall data to backup. So my question is how can i do this. Im on a Windows 10 22H2 Machine, and i am a pretty expirienced computer user.

Hello, I need help. I downloaded and installed Firefox (latest version), the icon appears in the taskbar, but when I click on it, FireFox does not launch and I always get the same error message. I uninstalled, reinstalled, restarted the PC, but I still have the same problem, even starting from firefox.exe in Windows (C:) >Programs>Mozilla Firefox. Could it be possible that Microsoft is blocking the launch of Mozilla Firefox? Thank you in advance for your help. Attached is a screenshot of the error message. Fortunately, my Mozilla Thunderbird (15.4.2 (64 bits) works fine...
