Firefox 技術支援討論區

i use the same add-ons on my desktop and laptop. i open my laptop and click on synchronize and later i open my desktop. two of these add-ons on the desktop have disappeared! this is not the first time. what can do i, how can install it to prevent it does not happen again?

I am not able to download any kind of file, from any kind of website to my disk. I am able to select open on the download dialog, and this will open the file and save it to the temp directory firefox uses for this function, but this does not save the files to disk/the download folder like I want to. I am unable to "Save image as..." as well, since this is considered a download. There is no record of these downloads even being attempted in the download history.

Hi! I have latest version of Firefox installed on my PC. But sometimes I am programming for web. So I would like to have Firefox Developer Edition as well. But I don't want them both at the same time - one for my usual web surfing and another one for web programming using leading (or even bleeding) edge features.

How do I install and use them separately? I tried running Firefox Dev Edition installer, but it does not ask questions like where to install and which Firefox profile to use.

If I want to do a 'clean' install of MS Windows - Windows 11 Pro v 22H2 (Build 22621.1485) - where are FF's sttings stored & how do I restore them after the re-install?

Hi, I have some issue on the new updates on Version 101.0.1 (64 bit) Firefox auto-download all my files even when I am in view mode. Is there a way to disable this feature?

I have my saved login and password details from another browser in a CSV and would like to import them to Firefox. I initially did not have the 'Import from a File' option in the drop down menu of the Logins and Passwords tab. After following a guide that instructed to set signon.management.page.fileImport.enabled to true in the about:config page, the option appeared. However, the said option is unresponsive to any clicks. The drop down menu simply closes once the option is selected, without any other reaction.

I'm not sure if this is a related problem but I am also unable to use the Import Wizard that appears on performing Alt+F and choosing 'Import From Another Browser...' The Import Wizard window only appears with a message that says "No programs that contain bookmarks, history or password data could be found."

Firefox browser version: 103.0.2 (64-bit) OS: Ubuntu 22.04 (64-bit) Windowing System: Wayland

Funnily enough, the 'Browse..' button for adding images under this support question doesn't work either.

Hello, there is the note for FF 102 Release:While Bug 1771084 does not represent a specific vulnerability that was fixed, we recommend anyone rebasing patches to include it. 102 branch

Patch 1 and 2. 91 Branch: Patch 1 and 2 (Despite saying Parts 2 and 3, there is no Part 1). To clarify, so the current 102 release of FF does not 'contain any patch for that bug 1771084, and it's recommended manually to install these patches? Or they are already incorporated in the release?

Hi there.

This is my first post so bare with me.  :-)

We are deploying the 32-bit version of the Firefox Browser to 4 700 clients and the 64-bit version to only 8 clients; all clients on a 64-bit Windows 10 environment. We will migrate to Windows 11 22H2 this year. The manager for the 8 clients says he wants the 64-bits version just because it's...64-bits. No other reason.

I've read that the 64-bit version can not handle Java, Media Players like VLC and mayby some other plugins. Is that still so?

What is the main reason TODAY for using 64-bit Firefox Browser instead of 32-bit, except for the use of 4 GB+ RAM?

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?

Browser is FF Nightly 112.0a, but this is probably a bug in stable FF, too. "Always ask you where to save files" is checked, in preferences. Like title says, the "last download location" is stored, and works for downloading files, and downloading a SINGLE item in Tools\Page Info\Media (Ctrl-I), but if multiple items are selected (in Page Info\Media), folder opened will always default to set location, instead of last download folder.

Windows 10, Firefox will not load URLs or settings page. Uninstalled Firefox and downloaded a new copy. Upon install system error message attached appeared but browser appeared with all my bookmarks and loading error message (attached with bookmarks erased). New pages will not load.

Hello, I recently migrated to a new MAC and now when I download a file and click on "show all downloads", it opens the about:downloads tab and not the downloads list from the library. Is there any way to force Firefox to open the Library when I click on see all download please? Thanks

Every time I come across a file and click the link to either open or save the file, Firefox just downloads the file -- THEN it asks me if I want to open it or save it..? It's bugged and an obscene security threat if the browser is so easily willing to download files against my intention.

Before I'm asked, I have gone through the settings multiple times to ensure 'Always ask you where to save files' and 'Ask whether to open or save files" are checked. Behavior does not change according to settings.

Example 1. Click link for a PDF with the intention to open, read, and forget 2. Firefox automatically downloads the file to my download folder 3. Firefox prompts me if I want to save the file or open it

If I click 'open', the file stays in the saved location even though I don't want it to exist.

I recently purchased a dell refurbished computer, I set it up went and downloaded fire fox without any trouble. I restarted computer today and it would not accept password I called DiscountcomputerDepot.com help and they helped me to restart and they told me they would have to reinstall windows from computer. So I lost all my programs. when it restarted said would have to update windows. I have tried multiple locations and get this same message This download.mozilla.org page can’t be foundNo webpage was found for the web address: https://download.mozilla.org/?product=firefox-stub&os=win&lang=en-US&attribution_code=c291cmNlPShub3Qgc2V0KSZtZWRpdW09KGRpcmVjdCkmY2FtcGFpZ249KG5vdCBzZXQpJmNvbnRlbnQ9KG5vdCBzZXQpJmV4cGVyaW1lbnQ9KG5vdCBzZXQpJnZhcmlhdGlvbj0obm90IHNldCkmdWE9ZWRnZSZ2aXNpdF9pZD0obm90IHNldCk.&attribution_sig=c3e7484d24556be08270fa603b3ed24cad53bd6caaec3f9e3f355d5c37300daa HTTP ERROR 404 Please help ,I have only use firefox since I had a computer , about 25 years.
