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 Firefox browser (119.0 Windows 64-bit) is at "C:\Program Files\Mozilla Firefox" and always starts with the message "Hmm. That address doesn’t look right. Please check that the URL is correct and try again." What is Firefox trying to do?

I have a new iMac (sonoma): I've migrated previous data to this machine and updated Firefox, but saved passwords are having problems. Some of my paid subscriptions are not letting me sign in, either through saved pws, or doing it manually. A few others seem to work okay. I've tried a few on Safari, where they work, so I suspect I have to change a setting in Firefox. But what? Any advice gratefully received.

Hi Support Team,

I had a Firefox old & important data (Bookmarks, password..) in non-functioning old PC, but Hard disk has with old folders. Could you please help me to retrieve old data into new PC Firefox browser from hard disk or another method.

Thanks Oshada

In older versions (say, Firefox 85 which I have been happily using until now) you could enter the search shortcut (say, "y" for youtube), then just press enter without entering any search terms, and be brought to the main page of that search engine. In fact, search engine definition file has a specific field for that feature.

Well, I'm on FF 119 now and I find that this behaviour is broken. You MUST enter search terms now.

Is there a way to fix this pointless change, or do I have to downgrade?

Sometimes, firefox will download the same file twice (or more) when I still have it.

I do NOT want to turn off automatic downloading.

I am asking, how to make firefox check if the file already exists before downloading.

I understand that sometimes you willl download multiple files from a website, but, even though they are all called "image.jpg" they are all in fact different pictures.

So, I think the solution to this is, when downloading a file, firefox should check if the file already exists.

If it does exist, start the download for file(1) as usual, but ask the user

"A file with this name already exists, are you sure you want to download it again ?"

And the choices should be

Yes (download continues) yes, and do not ask again for this filename (download continues) No (download is interrupted and partial file is deleted)

Hello,

I can't access my account anymore, this one was created by linking the mail address used for the account which apparently i never did. I tried every password i commonly used and none of them worked, so I think that this one was auto-generated and then saved, in my firefox account... What is really killing me is the 7 years of bookmarks and password that are locked behind this password, i can access the account by password recovery but that would defeat the purpose since I just learned that its linked to my data. I just changed my OS back to windows so file recuperation is gonna be a pain/impossible. The way i understand things i have to make my peace with all the websites I accumulated for years (and also the PWs) or wait and don't touch my PC because the firefox folder that was deleted was on the same HDD that i used for the new OS. Of course all of this wouldn't be a problem if I didn't have had a problem to my phone and send it back to the constructor for the warranty, which means if I'm not mistaken that my account just lost it's last link to me, except the auto-destruction button. Is starting to learn cryptography my best bet to reach my account ? Or is there something I didn't cover and there still a way ? Please tell me it's still possible.

Hello

since version 119 of Firefox a download behaves siometimes different. The directory and "Ask before save" are still valid. But sometimes Firefox start to save in the directory without asking. Why behaves version 119 sometimes different in comparison with previous versions like 118?

Kind regards

I am hopeful you will be able to help me. All open tabs NOW disappear after power failure or Comcast temporarily loses service or I restart my computer. This never happened to me before ~ if my computer was affected by outage or I manually restarted it a message came up to click on asking if I wanted my tabs restored. 1 click and they were restored ~ that option is not available to me now. It's frustrating and time consuming for me to "look" for, and "try" to find those tabs I had open. If someone does respond to my question I won't know its been done unless I receive an email because I'm not certain I can find my way back to this support page, primarily because I cannot remember HOW I even found this page in the first place! I bookmarked this page so perhaps I will be able to return to it. Thanks for the "How to restore tabs" help I HOPE you can give me. Marilyn West

as the title states, pages show up all messed up and i have no idea why, already ruled out cookies and extensions as well as the page itself Attachment should provide visual aid to the problem

Hi, Mr. or Mrs. The website has blank pages (page cannot be accessed). Utilizing https://xnxubdvpnbrowser.online/ The page is blank even though it looks like it has been contacted at the upper left. Is there a reason Brave is unable to load the website correctly?

Hi

What is this "app.update.background.rolled out" setting?

 /**
  * Background Update is controlled by the per-installation pref
  * "app.update.background.enabled". When Background Update was still in the
  * experimental phase, the default value of this pref may have been changed.
  * Now that the feature has been rolled out, we need to make sure that the
  * desired default value is restored.
  */
 async ensureExperimentToRolloutTransitionPerformed() {
   if (!lazy.UpdateUtils.PER_INSTALLATION_PREFS_SUPPORTED) {
     return;
   }
   const transitionPerformedPref = "app.update.background.rolledout";
   if (Services.prefs.getBoolPref(transitionPerformedPref, false)) {
     // writeUpdateConfigSetting serializes access to the config file. Because
     // of this, we can safely return here without worrying about another call
     // to this function that might still be in progress.
     return;
   }
   Services.prefs.setBoolPref(transitionPerformedPref, true);

When I opened Firefox, the message below popped up for a few seconds, then disappeared: CAD 3.8.2 - Some site data, including 1 Cookie(s), removed from 1 domains(s), including addons.mozilla.org...

Can anyone explain this, and should I be worried (CAD is a Python term used in uploading code). Thank you.

I used to be able to access my email with previous versions of Firefox but cannot anymore. When I attempt to sign in it just goes back to sign in page. I have to use another browser to access my email. Is it possible to go back to a previous version of firefox?
