Firefox 技術支援討論區

I've got about 10 bookmarks with links to support pages each about adjusting specific about:config setting to my needs. My job also requires me to change systems lots of times, from Mac to windows to Linux. Is there an easy way I can save my personal about:config changes to a file for easy import on other systems?

Thanks

Hi,

I hope you are well.

I have set up 11 custom devices that max the min and max sizes of bootstrap grid system (xs-min-360w, xs-max-575, etc) to aid me with checking my website on various screen sizes. Is there anyway to export this list or better still to synch them with my Firefox account so I don't lose these settings?

I am using Firefox Developer Edition (101.0b6 (64-bit)) on Ubuntu 20.04.

Many thanks Kaz

I can't open Firefox. When I click on the icon Bing shows up. I downloaded the latest version of Firefox, I can't install it because I get the message that I have to close Firefox because it is running. How can it be? I haven't been able to open it for weeks.

Hello,

Currently running MacOS Montery but the problem was still occurring on previous versions.

Whenever I use the green top left button to enter full-screen, the app immediately freezes and either crashes or has to be manually force quit. There are no reports in about:crashes and I there has been no success with troubleshooting mode or switching versions of the Firefox application.

Machine Info: MacBook Pro (16-inch, 2019) Processor: 2.6 GHz 6-Core Intel Core i7 Memory: 16 GB 2667 MHz DDR4 Graphics: Intel UHD Graphics 630 1536 MB

Any help towards a solution would be appreciated. Thanks!

Good day,

Really happy to see that mozilla is tightening up security. But unfortunately, I can't enroll into Two-Step Authentication everytime I enter code it's not being accepted. I tried multiple android apps of those codes and non of them work for me.

Because of that, I lost access to addons.mozilla.com account, because system doesn't let me in without 2step auth enabled.

Any chance I can use yubikey's intead of those auth apps? or anything else I can do?

if there's not already an option to autohide the bookmarks toolbar (like the address bar and tabs when in F11 mode [fullscreen])

can there be?

so like, on default the bookmark toolbar wouldn't show, but when I move my mouse into the specified area it appears (with the same animation as f11 mode)

 thank you,

let me know if i can already do that and if I'm just dumb.

 just to be clear, I want the tabs and url/address bar and tabs to always be there.

Actually might be cool to have options to autohide the tab bar too (separately).

 thanks again,

graham

Greetings. I can't open most sites I usually visit (even google.com) via my Firefox 98.0a1. This happens since today. All error codes are SEC_ERROR_LIBRARY_FAILURE.

Tried to:

• Disable DNS-over-HTTPS.
• Disable HTTP/3.
• Disable proxy (never had it enabled anyway).
• Disable sending info to Firefox developers.
• Change settings of DNS-over-HTTPS.
• Restart the browser (after each action).

Nothing helps me... But I still can visit some websites, but most common resources are not working for me. Please help me because I can't use Microsoft Edge without getting mentally ill. :/

Hello Everyone,

After inserting the proxy information, webpages in the container tab refuse to load/connect, I insert the IP address and I've also tried the Fully qualified domain name, using the type://host:port syntax, I get "The proxy server is refusing connections" and "The connection has timed out" error messages.

If I setup the proxy via the settings menu the entire browser uses the proxy server address, I am trying to specify a different proxy server for each container.

Please help me.....

found a bug with firefox 101.0b5 website https://www.express.co.uk/ it does not display the comments for an article. Works with Microsoft Edge

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 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.

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?

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 cannot watch a video on youtube when it is in the process of being live streamed. I remember a time when I was able to, years ago, but I can't any longer. I'm not sure what has changed. I found an article that says to install the optional update called "Windows Media Pack" in apps and features, but no app with that name exists. It was only a year old solution, so I'm unsure of what changed so significantly. I just installed another optional windows update, and also updated the browser, but still doesn't work.

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.

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

       BrowserViewSource chrome://browser/content/browser.js:3207
       oncommand chrome://browser/content/browser.xhtml:1

I have tried everything I know (I think) but Firefox won't allow me to stay logged in. How do I accomplish this??? I have researched online and still have not been able to accomplish this.... Google Chrome is no problem.... I stay logged in to it, but not so with Firefox... Help!!!!

Hello! Short story: I recently discovered that adding a new GIF image to a page resets the animations of existing GIF images on the page with the same src.

Expected behavior: Adding a new GIF image to the page should not reset the animation of existing images with same src.

Actual result: Adding a new GIF image to the page resets the animation of all existing GIF images on the page with same src.

Code with example: https://codesandbox.io/s/heuristic-platform-jsguir Video demo: https://www.youtube.com/watch?v=k-ZMrrqq_KI

Simplified version of the code showing unexpected behavior: https://codesandbox.io/s/elastic-shtern-vwrcx1

Does anyone know why this is happening? Is this a bug?

Browser: Firefox Developer Edition 102.0b4 (64-bit) OS: Windows 11

The partial code is :

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

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