Firefox 技術支援討論區

Hi there,

I have a laptop running Windows 10, plus the latest version of Firefox. The laptop has a built-in webcam. I have also connected an external webcam via USB. This second camera is better quality and preferred, I visit a web site. When I first activate the camera, I am presented with a dropdown of available cameras. The USB camera appears in the list. All is fine. I instruct Firefox to "allow" this camera to be used. (first image) However, after a short time, less than a second, the same dialog is shown again, this time without the USB camera. (second image) There have been no actual hardware changes. I can then click "allow" again and the *integrated* camera works, i.e. not the desired camera. So, two questions, really. First, what just happened? Did Firefox try to control the USB camera, find that it couldn't, and redisplay the dialog showing only the "controllable" option? Second, my desired endpoint here is for the web site to use the USB camera. How do I achieve this? I can easily do this with Chrome but I like Firefox. TIA.

hello! i'm looking for a way to adjust the settings, if there are any, to copy and paste PNG images with firefox and keep their transparency intact -- rather than the solid black it has now. as i understand it there's been similar issues as of 8 months ago, but i'm unsure if anything else has changed in that time.

i'm not a full-on graphic designer or anything but i do use this fairly often as an artist to look at references and such, and as someone who's recently switched to firefox from chrome (which does support this feature) i'd like to know if it's as easy as clicking something in a menu or if that's not an option altogether. thank you in advance to anyone willing to help!

I am using MacOS Monterey 12.7.1 with the latest Firefox version. When in full screen mode, if I want to refresh the screen I move the mouse pointer to the top of the page to get the tools to display but when I move it down the the refresh button, it quickly hides again before I can refresh the page. Does anyone know of a solution to this or a keyboard shortcut I can use to do a page refresh while in full screen mode?

Hello everyone,

I've been using Firefox for quite some time and I always keep a bunch of windows open throughout a few workspaces on my laptop. However, this takes up a lot of resources and looks very messy. So, I've been thinking of writing a script/extension to simply store all the open links in a window to a named list that I can, then, come back to when I need and reopen. That way, I could possibly have different lists, separated by topic and stored in a single place.

I'm sorry if there is an obvious solution for this, I saw a couple of similar questions have been asked before, but none that I could use as reference.

Thank you for your time, have a nice week!

Hi,

I'm looking for a plugin or website that is able to convert voice to text capability on Firefox. For Chrome there are many solutions (VoiceNote II, Voice Recognition, Dictanote). And I need to use it on firefox.

In firefox, as I think, permissions settings/UI haven't yet been sorted out however, so permission can't be granted to use it by the user, so it can't be used.

Thank you!

When I open Vivaldi browser, the link in the address bar is highlighted right away. That's not the case in Firefox. Here I to either need triple click or use "CTRL A" The same is true when I open a new tab.

Is there a way to do that in Firefox?

Thanks a lot /Per

I can't figure out how to get Firefox to autofill info like my email addy, name, phone number, etc. What is the secret - so annoying to have to type this stuff over & over again. Makes me miss Chrome.

Thanks for your help!

I often use two firefox windows each with several tabs opened

Problem is when I quit in this state sometimes only one of those multiple windows gets opened on the next launch

To quit I do a `ctrl + q` or right click `Quit` from launcher bar

Is there a setting to tell firefox to always relaunch with the same set of windows ?

I use sync and this happens when using the same computer for the exit then relaunch of firefox

firefox release 112.0a1 (2023-03-05) (64-bit)

Ubuntu 22.04

Title is self explanatory. When I try to take and save a screenshot in my browser, either when right clicking and selecting Take Screenshot or using CTRL + SHIFT + S it always cuts off some of the image I'm trying to take. Any ideas on how to get this fixed?

What's the best easiest way to translate my website https://invivobio.net/ in different language. We have different countries visitors so I want to check/translate my English content in different languages after publishing them, so it will be understandable for me and visitors to check the language, is that correct?

Can anyone suggest me Mozilla Firefox Extension which translate perfect because I leave Google Chrome due to slow browsing. I am enjoying Mozilla for the long time, so I don't want to move back to Chrome.

Your suggestions will be highly appreciated.

Hi, on my current Firefox setup, I have a search engine shortcut in my Top Sites on a New Tab page. It's a quick one for Amazon, I can't figure out how to add others though. I saw reference to it in this old support issue, but I can't find how to do that anymore.

I want to print a page. But without the header and footer stuff (because it is ugly and I don't want others to see the information). There are a lot of old pages here and on other places about how to do this. They are unfortunately all deprecated. What is the way to do this as of 2023? OS is Windows, btw.

Hi, I discovered that in order to achieve that, you set in about:config "permissions.fullscreen.allowed from the default false to true. The default behavior does not stop the video with a single left mouse click, but triggers full-screen. It would make sense to make "true" the default as it seems more intuitive to control both the play and full-screen in that way.

The issue I am facing, and for which I direct my question to all you intelligent beings, is that my network is being hammered by connections to firefox-settings-attachments.cdn.mozilla.net.

When looking at the squid logs, I see the following: access.log:1678216931.488 170104 1.2.3.155 TCP_TUNNEL/200 11400353 CONNECT firefox-settings-attachments.cdn.mozilla.net:443 - CARP/1.2.2.11 -

If I understand correctly, this connection is to download new files that pertain to security, cert revocation lists, blocklists, plus a bunch of non-security related stuff.

The question is, how do I make this file downloaded as small as possible while still keeping the security bits... (saw this page, and followed what I thought pertinent https://support.mozilla.org/en-US/kb/how-stop-firefox-making-automatic-connections) The second question is... can we do a scheduled window to perform these downloads?

If you are asking why I am having network issues over 11 Mb, the answer is that all my clients go through a corporate proxy... We have many thousand devices and last time we choked the network with 80GB downloaded on a timeframe of 15 min.

Thanks much!

Is there a way to make Firefox open with a fixed size? It currently opens with the last size. I frequently resize a window for a specific site, but don't need subsequent windows to open to that size.
