Firefox 技術支援討論區

I have a slight problem. I'm currently using Firefox 116.0.3 and it seems that it can't update. The automatic updating will run, and then it will fail (this is all the time when using Firefox). It will recommend me to download the newest version from the website, but then the CDN will and I will be presented with the "connection was reset" error. This happens both on my Windows 10 and Windows 11 machines. Both are running Firefox 116.0.3.

Funnily enough I tried to see if I could download the newest version on Edge (Chromium), which it could but the version I got from the website was the same version I have now. I wonder if this is something to do with my region as I'm based in China and I'm aware that some software can have...problems.

Also, when trying to download version 122.0, it is fantastically slow and will often fail to complete.

Is there anything that could be suggested as I really don't want to use Edge.

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.

When I do the keybind (Control + P) or press the print icon in google apps (google docs, drawings, etc) it automatically downloads a pdf instead of opening the print menu. Chosen solution

Printing on any other site pops up with the printing options. Only on google apps does this happen, including gmail.

This problem is non-existent on Google Chrome and Edge. It does persist on Brave although. Haven't tested any other browsers.

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?

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?

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?

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.

Dear community,

As I use a few self-made unsigned add-ons, for several years now I have been using the Firefox unbranded builds on Linux with great joy. In the past these became available for download shortly after a regular Firefox was released. Lately though things have changed. The current latest release for unbranded is stalling at version 107. So it's getting further and further away from the official Firefox, which is at 109 at the time of writing.

Obviously I'm concerned my unbranded Firefox is not getting the same security updates any longer. I do realize there's alternatives for supporting unsigned add-ons. Running a Firefox nightly or developer-edition is something I'd want to avoid, so for me these aren't real alternatives. I've also tried tracking unbranded info on bugzilla.mozilla.org, but couldn't find anything relating to this 'lag'.

Where can I find more info on this topic? Are these unbranded builds being discontinuated?

Thanks for reading, keep well!

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

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. Many thanks Jack Terry. [email removed from public]

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.

I have just installed V.100 and have come across a small problem. I can't sign into 'The Canberra Times' site. The option to sign in is missing from their home page. It is there using MS Edge or Chrome and I can login to the site on those two browsers. This does not seem to be a problem with other websites that I have tried since the new version!

I can't even begin to imagine what might be going on with a situation like this! Thanks.

Firefox wasn't working well on a seldom-used laptop, and the update to 100.0.1 didn't go quite right, so I deleted the old version and (using the odious Edge) tried downloading a fresh copy of the software.

But then I get a message from "7-ZIP" that reads "Can not create temp folder archive"

I'm stuck. Advice?
