Firefox 技術支援討論區

I just installed the latest Version of Firefox 101.0 for Windows 10. Then when I tried to download a pdf file from my yahoo mail I received the following message: "Problem loading page" Firefox Can’t Open This Page To protect your security, dl-mail.ymail.com will not allow Firefox to display the page if another site has embedded it. To see this page, you need to open it in a new window. Learn more… Open Site in New Window Report errors like this to help Mozilla identify and block malicious sites

So, in order to open the page I have to press "Open Site in New Window"

Please advice why happened this issue and how can be fixed.

Recently gmail stopped autocomplete addressees when writing emails in firefox. It still works with chrome. I've tried completely uninstalling firefox using revouninstaller and installing a clean version with no addons, but it didn't help. Any help will be greatly appreciated.

I've been having issues with the themes on the Firefox Browser. Almost all themes forces dark-mode on the browser. Since update 100 it no longer effects websites, but it still affects the browser (menues etc) despite me having the settings locked on light-mode.

I used Speedtest by Ookla. When the broad band was installed, the technician did this without a problem. Today when I tried I was taken to an installation page. After I used the SpeedTest, then my main page was gone and instead I have a bar of Firefox selected options. I've tried to find how this is done so I can set it back but I can't find it. Please help.

Hi,

Its about time you looked at your Mic cam Cam settings

I'm getting older, they should be set as on as Default, and switched to off if required

This is a massive issue to a great part of the community I don't use Firefox as I used to, as so many of my clients are also moving away, ( Gone to different platforms to Edge and Chrome) I'm sure this can be easily fixed.

I just had a glitch with the latest update to 102b, FF insisted I had an old version and would only let me make a new profile. So I had to set up multi-account containers again. I have specific sites opening up in each container, and I'd like to make a copy to make sure that if my profile gets goofed up somehow, I can always easily restore my setup with multiaccount containers just the way I like it.

What do I need to copy, so that with a new profile, all I need to do is copy over some files?

In my profile folder, I see an Extensions folder, as well as an extensions.json and extensions-settings.json.

Are those the only folders/files I'd need to restore multi-account containers on a new profile?

I have thought of using FF Sync, but I keep reading that it is not intended for copying, so much as sharing across different devices, which is not something I'm interested in. Should I just let sync copy my extensions, and then sign back in, in the event I want to restore addons to a new profile?

Since earlier this week my Firefox browser has been turning .jar files from GitLab into .jar.zip files, which prevents them from being used properly until renamed. Attempting to download the same files on Edge or Chrome works correctly, and attempting to download any jar files from other websites (even GitHub) also works correctly. It seems that GitLab is the only website that is affected by this.

Examples of files being affected (they should be downloaded as normal .jar files): 1. https://gitlab.com/Trafalcraft/antiRedstoneClock/uploads/3b3c84814d76810f826c3803eaca1e66/antiRedstoneClock-1.4.1.jar 2. https://gitlab.com/Aristois/ui-installer/-/jobs/2505715157/artifacts/raw/packager/Aristois-Free.jar 3. https://gitlab.com/Aristois/Installer/-/jobs/2495195255/artifacts/raw/packager/free/Installer-2.0.3.jar

I'm using Firefox developer edition (102.0b3), and already tried using private mode, resetting Firefox, and reinstalling. Since I use GitLab as a main source to upload files, many users have also complained the same problem to me, in which all of the users were running Firefox. After they downloaded with a different browser, it worked for them as well.

Firefox 102 beta stopped opening source of web pages in external editor

I have view_source.editor.external set to "true" and view_source.editor.path set to "C:\Program Files\Notepad++\notepad++.exe"

Before version 102, CTRL-U on any web page would open the page's source in the external editor.

In 102, the source is opened in the internal source viewer (in a browser tab).

The console shows:

   this._caUtils.getDefaultExtension is not a function viewSourceUtils.js:413
       getTemporaryFile chrome://global/content/viewSourceUtils.js:413
       openInExternalEditor chrome://global/content/viewSourceUtils.js:265
       openInExternalEditor chrome://global/content/viewSourceUtils.js:216
       BrowserViewSourceOfDocument chrome://browser/content/browser.js:3131

When I try to play iplayer as of June 2022 it comes up with error 5000/5001. Other tv players are no longer playing either, Channel 4 for some time now. My laptop runs on Windows 8 and I have the latest version of firefox. In plug ins my codec is set on always activate as is Widevine CDM. I tried unchecking 'play DRM controlled content' in settings then checked it again and it has come up with Widevine CDM will be installed shortly, but nothing has happened.

many thanks, frances

The partial code is :

< video onclick='playPause()' width='100%' controls >

 < source src='/videos/".$trimDir."/".basename($s)."' type='video/mp4' >

</video>

Good day.

My use case is the following. I use Firefox Developer Edition for developing websites. Usually the development happens on a certain part of the page. Most of the times it is not on the top of the page, so you have to scroll down to it.

Sometimes when the page is refreshed a jump to the top happens. So then I need to scroll down again. It takes a lot of time and concentration away if it happens dozens of times a day.

It often happens after I did some changes to the files on the page. It usually does not happen when I refresh the page a couple of times (when I purpously want to reproduce this problem).

I did try running Firefox in Safe mode, but it didn't help.

What can be done to fix this problem on my side? Is this a bug in Firefox itself?

I recently upgraded graphics cards from an Nvidia GTX 1080 to an AMD 6900XT. Since then I noticed video stuttering on YouTube while playing 4k videos, especially noticeable at 4k/60FPS (example video ). Prior to the upgrade, I was not experiencing issues.

I monitored task manager as the video was playing to see CPU usage, which was sitting at 25% (4 core 8 thread CPU). GPU usage was fluctuating from 1-3%.

I tried resetting all the changed configuration options in about:config, removing all add-ons, "Refreshing" Firefox, and ultimately uninstalling and reinstalling. Nothing has worked so far except for "Troubleshooting mode" in about:support. In that mode, I experience no stuttering and GPU usage rises to 25-35% with the video playing, even before I reinstalled.

This most likely isn't a networking issue as the "Stats for nerds" option on the YouTube video shows I have 10-20s of buffer while the video is still stuttering.

I would like to find out what's different about Troubleshooting Mode that is not giving me the same problem while in "Normal Mode". Any advice?

I have been seaching for the solution for the whole day, and i found the closest one. It Does remove tabs, windows buttoms, but the background bar still remains, and i dont need it this way. So thats the code i used to make it >>>>>

1. main-window[tabsintitlebar="true"]:not([extradragspace="true"]) #TabsToolbar .titlebar-spacer {

       border-inline-end: none;

}

1. main-window:not([extradragspace="true"]) #TabsToolbar > .toolbar-items {

 opacity: 0;
 pointer-events: none;

} /* This makes the bar shorter vertically but removes the 3 window buttons */

1. main-window #TabsToolbar {

 visibility: collapse !important;

} /* For full screen mode */

1. TabsToolbar[inFullscreen]{

 display: none !important; 

}

On the screenshot you can see what remains on tabs' bar place I need my browser to end just above the URL string, so there wont be empty space in the top of the monitor. Can you help me find solution for this problem, please?

Hello, Do not be tired

while i clicked on the normal Web page, Cursor is activate, And blink. it walks a lot on the nerves.

please solved this problem,

Thank You!

MacOS FF dev edition 102: I have a folder in my bookmarks toolbar, and I frequently open all of them in tabs. But that option is missing from the context menu on the folder. It is there at the bottom of the folder if I click to open the folder, but this is silly. There is an "open all bookmarks" context menu option on the folder, but that opens all the bookmarks in the toolbar, not in that one folder. why is this?

MacOS FF dev edition 102 When I roll my mouse over a link, in pops up the URL in the bottom left (i.e. status bar as safari calls it) but there's no indication of if the link will show in the current tab or a new tab. in safari, the end of the URL states "in new tab" if that's the case.

Lately when I attempt to download any pdf file I get the 'file name'.pdf with 'failed' as the result (when I check the Download icon on the FF status bar). I looked in my download directory and I found these 'failed' .pdf files with 0 KB and also some files (same name).pdf.part. I changed the file extension (deleted .part) to .pdf and the files would open in Acrobat. Nobody likes inconsistent problems, but occasionally a pdf will download normally!! But it fails more than it works. Using FF 102.0 (64-bit)

I had set up a userContent.css file in the past to pull up and fetch an image on my computer to display as a background on the homepage. It worked and did it's job until recently, when I had recently relocated a lot of my files around on my computer. I have redirected everything to where I want it to look, including the userContent.css file to the new location for the image I want as the background. Firefox loads the .css file correctly, and recognizes the file existing, but it won't load the image itself for some odd reason. It states it "may not load or link the file" because of a security error, and thus, can't load the image. I never had to deal with this before. How can I get Firefox to be able to load my image like I want it to? I have screenshots that I can provide, but this site doesn't want to upload them at the moment.
