Firefox 技術支援討論區

Hiya,

I use a theme which some years ago (after a change in the way Firefox handles dark-mode preferences) changed all UI and websites to use dark-mode. I was able to keep using the theme, and mostly override this behavior by setting:

`layout.css.prefers-color-scheme.content-override = 1`

However, this didn't take for some components, such as the sidebar and bookmark editor window, which still continue to use dark-mode.

Is there any way to completely disable dark-mode everywhere, and still use my preferred theme?

Cheers, Afraz

Hello, i have the issue that times are displayed in UTC as long I have enabled fingerprint protection. Is there a way to exclude time zones or to manually set the timezone I want?

I found this in about:config: privacy.fingerprintingProtection.overrides: string

Can I override the settings for the timezone?

Latest crash report: bp-c7581c18-335d-41c6-826e-383c40231009

Firefox blinks and then crashes when attempting to visit various websites, specifically Unsplash.com (a stock photo site) but also inconsistently on other pages including Google search results pages. I have tried refreshing, uninstalling and reinstalling, ensuring all my drivers are up to date, and disabling hardware acceleration and webGL. The only time the browser works consistently without crashing is in Troubleshoot Mode.

This blue icon recently appeared in the upper left corner, and it's there even when I watch video full screen. Clicking on it doesn't do anything. What is it and how do I get rid of it when I want to watch video?

Hi,

I am using Linux Mint 20.3, 64-bit and both Firefox and Chrome are not loading images for me on certain websites (i.e. okcupid). In particular, I am noticing that images will actually load for a split second and then disappear moments later.

I've tried disabling my adblockers, deleting my cookies and cache, running Firefox in Troubleshoot and Diagnose mode, running Chrome in Incognito mode, and evening uninstalling and reinstalling Firefox. Still the issue persists.

I followed the advice here: https://support.mozilla.org/en-US/kb/fi ... s-not-show

Any advice or suggestions would be most welcome.

Thanks, Chris

there used to be an add on called roomy bookmarks that stopped working so people found ways around to replicate it and it works on win 10 but I just switched to Win 11 and this solution doesnt seem to work anymore for me, anyone know if i need to change anything?

    Locate your firefox profile folder, in this article they say where you can find it: http://kb.mozillazine.org/Profile_folder
   Find your profile folder mine was: C:\Users\***\AppData\Roaming\Mozilla\Firefox\Profiles\***.default\
   Locate a folder called chrome (if it doesn't exists create one through your O.S) must be lowercase
   Locate inside chrome folder the file: userChrome.css (if it doesn't exists create one through your O.S, google how to create a .css file on notepad) Chrome must be cased as shown above
   Add the code: https://pastebin.com/1r6cc8hW
   Restart Firefox, now you are done, if you don't want text to be displayed within the icons just remove the last line. 

This is the line of code i have in css file that works for me in my win 10 machine.

/*

* Recreates the basic functionality of the popular Roomy Bookmarks Toolbar add-on in Firefox 57+.
* Uncomment the section with the functionality that you want, leave all other sections commented.
* This only affects toplevel toolbar bookmarks and folders, bookmarks and subfolders in folders are unaffected.
* The tooltips on long hover (showing bookmark name and link) are unaffected.
*/

/* some margin settings, do not comment out */

.bookmark-item > .toolbarbutton-text {

 margin-top: -1px !important;

} .bookmark-item {

 margin: -1px !important;

}

/* No text on toolbar bookmarks; Text on bookmark folders. No hover effect. */

1. PlacesToolbarItems > .bookmark-item:not([container]):not([open="true"]) > .toolbarbutton-text {

 display: none !important;

}

1. PlacesToolbarItems > .bookmark-item:not([container]):not([open="true"]) > .toolbarbutton-icon[label]:not([label=""]) {

 margin-inline-end: 0px !important;

}

/* No text on toolbar bookmarks; No text on bookmark folders. Show bookmark text on hover. */ /*

}

1. PlacesToolbarItems > .bookmark-item:not(:hover):not([open="true"]) > .toolbarbutton-icon[label]:not([label=""]) {

 margin-inline-end: 0px !important;

}

does anyone have a workaround or a similar add on? i would like to have my booksmarks as shown in the screenshot on my win 11 pc as well.

My Firefox 118.0.1 on Win 10 (all current updates) is creating literally thousands of profile files daily. For example, at this moment there are 3957 profile files with names like

6D89348819C8881868053197CA0754F36784B4BFSF

in the directory C:\Users\(user)\AppData\Local\Mozilla\Firefox\Profiles\ywlawdlc.default-release-2\cache2\entries

There are also thousands of other profile files in folders from previous dates.

What is the purpose of this many profile files, and how do I stop their creation in such quantities?

Thanks Dave

I posted earlier about a search settings problem. I have been monkeying with things until I got a reply7 that led me to a fix. Except now I cannot see my addons on the toolbar and can't figure out how to make them visible. They seem to be there if I scroll over the spot but are not visible to me so that I can use them. Right click gives me the drop menu but left click gives nothing. And how do you get rid of that dang puzzle piece thing?

I have FF set up to use only DDG. Part of this setup is that I have removed all other search engines from search options. Today Oct 7, 2023, when I booted up things were normal. About an hour ago I entered a search term in the browser and the search result came up on google. That should not be possible. I checked my settings and sure enough google has been added and placed atop DDG. Furthermore google cannot be removed when selected, the remove button is greyed out. The remove button is not greyed out when DDG is selected. !? What happened and how do I fix it?

i posted a crash question yesterday and got an email asking me to post these the time is the same i assume because i hit "submit" at the same time for all of them i'm posting blind here because there was no link in the email back to my original post - maybe something else that should be fixed

in firefox, tabs or bookmarks or anything dragable like downloads dont drag. I click and hold on them but nothing happens. I can drag whole windows, so it's not windows problem. When i restart my computer, the problem disappears for a little while but comes back.

Any help? Thank you

Hi, I am using Firefox 118.0 for Fedora that comes with my Linux distribution (Fedora 38 Kinoite). Everything was working fine, but as of today, when I try to start Firefox from a taskbar, my entire desktop goes black for a second and then returns to normal with Firefox not starting as if I didn't click on the icon at all. However, if I open the Terminal and run Firefox from there, everything works fine. I am not sure if the problem is related to Firefox, KDE Plasma or Fedora, so I will start here. I attach my system info below.

Terminal output (Firefox works fine from here): $ firefox Crash Annotation GraphicsCriticalError: |[0][GFX1-]: vaapitest: ERROR (t=0.40708) [GFX1-]: vaapitest: ERROR Crash Annotation GraphicsCriticalError: |[0][GFX1-]: vaapitest: ERROR (t=0.40708) |[1][GFX1-]: vaapitest: VA-API test failed: failed to initialise VAAPI connection.

(t=0.40708) [GFX1-]: vaapitest: VA-API test failed: failed to initialise VAAPI connection.

Operating System: Fedora Linux 38 KDE Plasma Version: 5.27.8 KDE Frameworks Version: 5.109.0 Qt Version: 5.15.10 Kernel Version: 6.5.5-200.fc38.x86_64 (64-bit) Graphics Platform: Wayland Processors: 8 × Intel® Core™ i7-8550U CPU @ 1.80GHz Memory: 15.5 GiB of RAM Graphics Processor: Mesa Intel® UHD Graphics 620 Manufacturer: LENOVO Product Name: 20L8S0SA00 System Version: ThinkPad T480s

Hello, trying to verify the integrity of firefox-118.0.1.tar.bz2 I realized the GPG key has changed.

The following blog post details the change and shows the new key: https://blog.mozilla.org/security/2023/05/11/updated-gpg-key-for-signing-firefox-releases/

But when I download the key using the link provided (which points to keys.openpgp.org) the key I get is different from the key posted on the Mozilla blog page.

What is even more strange, is that the key from keys.openpgp.org declares in the comment that 14F2 6682 D091 6CDD 81E3 7B6D 61B7 B526 D98F 0353 is the fingerprint of the key (the same that is posted on the Mozilla blog) but it can't be because the key different.

So my questions: 1) Why Mozilla is posting a link to a key that is different? 2) Why keys.openpgp.org shows the correct fingerprint with a different key?

And, in the end, which key should I trust and why.

Thanks.

The horizontal scroll arrows are not working on Amazon prime video using Firefox on a pc running Win10.

It hasn't worked for some time and I thought it was an Amazon problem, but I've tried other browsers and devises and it works on all of them EXCEPT Firefox.

My Firefox for pc is up to date. I have uninstalled and reinstalled twice. I have tried cntrl +/- thinking maybe I just wasn't seeing them - they're not there. All drivers are up to date.

I don't want to use another browser but i use Amazon prime video a LOT and this problem makes it nearly useless. HELP please?

I don't have the option to see or edit my saved credit cards in firefox's settings, autofill still works but I can't make any changes to my cards. I went into about:config and made sure both of the below setting are set to true and they were and it's still not working, there are no settings to change the autofill

extensions.formautofill.creditCards.enabled extensions.formautofill.creditCards.available

as of 2023/09/29 hulu, netflix, prime and disney+ are not playing videos on firefox, after making zero changes to settings or configuration.

I tested Netflix on Google Chrome and videos played, confirming this is a Firefox issue. I cleared recent/all history and changed passwords for those sites. Netflix logs me out if I attempt to play content. Speedtest reports 200 mb/s. Mozilla VPN is installed but turned off. Netflix sign in reports a new device/login in my state which is different from the VPN setting so this confirms that the VPN is not active and blocking content. HBO/Max videos play correctly and that site does not have the same issues. Firefox has crashed numerous times in the last two weeks. Sometimes just a single tab, sometimes a full application insta-quit.

I prefer to compartmentalize usage across different browsers for privacy/security reasons and would like to continue to use Firefox for these streaming services.

Is it possible to spell check the entire web page using both Hunspell built-in dictionaries and user-defined dictionaries *.dic, already prepared text in Firefox. As it is done in text editors like Libre Office (also uses Hunspell) but for web site, checking the text from top to bottom with errors in a separate window, so spell check is not only in the text input/search field.

On Firefox Developer Edition, the URL is displayed in full with protocol and subdomain greyed out, domain name shown clear, and URL path also greyed out, as is standard. Examples attached include developers.cloudflare.com and chat.openai.com

However, I've noticed on a few domains the subdomain is not greyed out and shown clearly like the apex domain. Examples attached include uwu.ai (a paid subdomain provided by carrd.co) and pages.dev (default subdomain for Cloudflare Pages).

What manages this behaviour? Why do some subdomains get treated as apex domains would on Firefox Dev?

Mouse is Logitech MX Master 3 for business. When I scroll on Maps to zoom out or in, it zooms all the way out or in, even when I just do one "scroll click". Scrolling up and down works fine on other websites. Using the scroll wheel for zoom in Google Maps in other browsers (latest versions of Google Chrome, MS Edge, Brave) works as expected/fine, there it only zooms out/in one level.

It's not a new issue, it's been here for a long time, I just haven't bothered doing anything about it.

I have found another old thread about the same issue and the suggestion was to disable hardware accelleration. I tried that and it made the scrolling worse, but same thing happens, just slower and with choppiness. I have tried running troubleshooting mode. Still the same thing.
