Firefox 技術支援討論區

Moderators, I am copy and pasting the below warning I have seen on similar posts at the top of the post.

--- WARNING: This script is not provided by Mozilla and is not officially supported Creating a userChrome.css file and other ways of customizing Firefox that are not exposed in the interface are there for developers, not end-users. If it were intended for end-users, you would see a menu option or checkbox; you wouldn't have to hack a text file in a hidden location.

What this means is that even though the functionality you want is no longer supported, a third-party has found a way to do it using the CSS file. If it breaks in new versions, you will need to contact the person who provided the script.

[Warning was not added by moderator, but by me to save someone time.] ---

With that out of the way, here's the issue I have, how I've solved it temporarily for the community.

When I load YouTube videos, I am given a statuspanel message with the URL of the video playing. It's not momentary or temporary, it stays there, the entire time. Why anyone thought this was a good idea, I'm not sure.

My question is simple, is there an alternative solution - to remove this statuspanel message permentantly - to what I'm sharing here, without using the userChrome.css file?

If so, please provide the solution so it can be tested and upvoted by the community, thank you in advance if that is you.

If there is not, then this post also serves as solution as well as a request to Modzila, that being.

Modzilla. Please make a solution that doesn't need custom .css scripts.

I am posting this as I needed multiple posts to achieve a solution so am hoping this serves as that for someone (including myself) until Firefox resolves this issue themselves, another way.

Solution: Windows 7/8/10/11 as of Firefox version 120.0

1. Go to about:config, click Accept the Risk and Continue 2. Type "toolkit.legacyUserProfileCustomizations.stylesheets", toggle this to true 3. Close all instances of Firefox 4. Open Explorer, navigate to %appdata% then navigate down to \Mozilla\Firefox\Profiles and select your profile folder. If you only have 1 it may be obvious, if not for me it's the only "~.default-release" folder, where ~ is a random set or letters and numbers. If you're unsure, pick the first folder named like this, then repeat the next steps for all profile folders, or use trial and error if you prefer until you achieve the desired result. 5. Make a new folder "chrome" in that folder. 6. In this folder make a new .css file, right click make a new .txt file rename the file and extension "userChrome.css". 6. Open the blank .css file with a text editor and paste this line without quotes "#statuspanel {display:none!important;}" and save. 7. Attempt to load videos or pages where messages usually appear in the bottom left and observe the results

There are various other posts both here and other places that I have combined to write this solution, none of the others worked on their own, for me, which is why I write this and to refresh the request to the Modzilla Firefox team, to please, share or make a solution so we don't have to do this, as you'll otherwise need to continue supporting this legacy feature in future versions of Firefox.

Note: This will likely remove all statuspanel messages on other pages too, I have read other statuspanel commands online so if you want to be particular about muting some and not others, you may need to modify the file further.

My apple computer performed an uninitiated re-boot and now the Firefox icon in the task bar does not show Firefox as running, but when I click on the icon it tells me that Firefox is open and it cannot open another window. How to I shut Firefox down and re-start it?

Constantly seeing websites loading with these unusual fonts. I deactivated the setting which allows websites to render their own fonts and have disabled seversl add ons with no resolution. I am on Mac OS 14.2

Have sold loads on Ebay using only Firefox as the browser. Tried to list another item a few days ago, and after entering the details on the first page (Item description and section to list it in) couldn't get beyond that page. The next page appeared not blank but as light grey filled rectangles where the text etc should be. Obviously tried reload. Same over the next day or so. In desperation, used Edge. No problems with that, using the same first page which Ebay had stored for me. Just tried again with Firefox - same fault.

I recently took a hit from potential malware while looking for a owners manual. I now have a popup that looks like the one attached. It looks to be from Mozilla, but I can't be sure. Can you help with this?

Hello there,

while trying to stream a Live-Stream i unfortunately get the following error, while the stream is loading: "Playback cannot continue. No available working or supported playlists."

Is anybody else encountering this issue?

Thanks in advance.

Sincerely

I have a subscription to Global Cycling Network, to which I login using my Google account at https://plus.globalcyclingnetwork.com/login. The login web page has options to login using Google, Facebook, or Apple, but in a normal Firefox window, the buttons for using these logins never appear - I just get a whirling circle where the buttons should appear, and the page never completes loading. If I open the GCN login web page in a private FF window, the buttons appear and I can login without any problem. If I use Firefox Settings to clear all cookies and cached web data, then close and restart Firefox, I still can't login from a normal FF window.

I tried the Edge browser (OS is Windows 11) and login there works without problem

Any suggestions on a fix to get it working on Firefox? FF is presently version 119.0.1.

Hello all,

I'd like to now if it's possible to roll out a version of Firefox with password manager disable. While still be able to have the account option enable so Bookmarks and History can be synced.

As my work place has disable Firefox account sync saying they cannot disable Firefox password manger.

If someone could please if this is possible is so can you share how this would be done.

Thanks, Nathan.

Hello, I need help. I downloaded and installed Firefox (latest version), the icon appears in the taskbar, but when I click on it, FireFox does not launch and I always get the same error message. I uninstalled, reinstalled, restarted the PC, but I still have the same problem, even starting from firefox.exe in Windows (C:) >Programs>Mozilla Firefox. Could it be possible that Microsoft is blocking the launch of Mozilla Firefox? Thank you in advance for your help. Attached is a screenshot of the error message. Fortunately, my Mozilla Thunderbird (15.4.2 (64 bits) works fine...

For some reason my Firefox on my Mac and Windows computer won't sync even though I am using the same account. I would like my Mac to look the same as my Windows computer. I have tried logging in and logging out on both, all the basic fixes but nothing has helped.

Thanks.

A couple of weeks ago the scroll wheel on my Logitech mouse stopped working with Firefox. It works fine on all other applications on my computer but will not work on any web page or any Firefox menu. I am not using XMBC. I updated to Firefox 119.0.1 this morning and it didn't make any difference.

When I have sent an email, it is not seen in 'all mails' nor 'sent emails', it is attached to a thread, when I open the thread, I have to go through many 'header' emails to find it at the bottom. Why is my last email NOT in 'sent', not in 'all mail' - or if it is on the thread, not seen at the TOP, displayed, ready to reply. Sending me nuts. Please advise how I can customize - to see the emails sent and received in REAL time. Currently my sent mail has so few in the folder. How can I stop this. I want All Mail and Sent mail, at the time I sent them. Not buried, Not as threads. I have tried removing threads, and it think it wants to delete them, I don't want that.
