Firefox supportforum

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.

Some websites display poorly on Firefox 119.0 on my Dell computer running Windows 11. Some of the letters of the fonts are too thin and hard to read. They display correctly in Edge.

I have used Inspect Element to see that the font is: font-family: Roboto, Helvetica, Arial, sans-serif;

The problem goes away if I change this to: font-family: Helvetica, Arial, sans-serif;

I do not have the Roboto or Helvetica fonts installed on my computer.

The problem fixes itself if I turn off the setting for "Allow pages to choose their own fonts, instead of your selection above." However, this is not a good solution, because it introduces other issues.

Any help or suggestions would be greatly appreciated.

I have researched this for several hours and tried many of the suggestions online.

1) I have disabled all extensions. 2) I don't have any Themes installed in Firefox. 3) I have tried "Smooth edges of images and text" turned on and off. 4) The problem still occurs when running Firefox in Safe Mode. 5) I don't have a "High Contrast theme" enabled in the OS settings. 6) I am not running uBlock Origin. 7) I have played with Clear Type but the problem was occurring before that. I have tried modifying Firefox's gfx.font_rendering.cleartype_params.gamma to the value of GammaLevel from Windows's registry Computer\HKEY_CURRENT_USER\Software\Microsoft\Avalon.Graphics\DISPLAY1. 8) I haven't installed any fonts on my computer. 9) I tried setting security.sandbox.content.level = 1.

4 PM, November 7, 2023 EST. The "About" page of all YouTube channels suddenly disappeared, whatever the the login status. A compressed version will show up from a channel's home page when clicking on the site description from its Home page. Make things weirder, ~6:15 PM it WAS visible from the Tor browser but started acting the same. I have no ad blockers, or ANY extension installed on any apps, including Firefox/TOR browsers. Updates to both browsers were made prior to this behavior. It may be Google/YouTube's fault but it's becoming frustrating because I prefer Mozilla's browsers over Edge or Chrome.

PLEASE HELP!

So I opened firefox as usual, which automatically restores my previous session, but only one tab was showing, and the rest were blank and had no addresses. Then I opened firefox again after closing, and only the last tab, of the previous tabs was showing. After that I looked for restore last session, but it was nowhere to be found. What I did find, was restore recently closed tabs, so i selected that. But of course, these were the recently closed tabs, and not my previous session. After looking around on the internet, I quickly found sessionstore files, but at that point, my past files had been updated.

Where does firefox house deleted/updated files? And how can I recover "previous" sessionstore files?

PLEASE HELP!

I am unable to play any videos on firefox only because of this WidevindCDN crash messages. i have updated firefox to the latest version and restarted the device and tried again however this error keeps showing up and doesnt let any video play. Please fix

Firefox is running x 8 in my task manager at the moment. Why does it keep multiplying and slowing down my computer? I am almost ready to uninstall Firefox. If I merely need to revert to an earlier version of Firefox, please let me know how to do that. Thank you. Shannon

I've created 22 themes and in all of them the drop down menus such as "downloads", "history", "extensions", and "application menu", all became white instead of dark like they used to be. I really don't want to go through the process of fixing and reuploading them, I'd apprecate you looking into this and hopefully fixing it with a simple update. Please fix this problem, thank you!

Hello, I've got a reproduction issue on France TV live programs which I watch through nordvpn. The picture keeps "jumping" fast up and down in a very bothering way. This doesn't happen when the video is NOT live. I run the latest version of LINUX MINT. What can I do to fix it? The only way I found to stop the issue is to take down the resolution of the live video to its minimum which gives me a disastrous picture but stops the "jumping". I guess you might say there is something wrong with my GPU. The point is that my PC is brand new with an AMD 5600G, new MB, 16Gb of RAM and 500w of PSU. BUT more than anything I have to say that everything WORKS FINE with CHROME. I like FIREFOX I have been using it literally for decades now. (I'm 75). Is there a solution? Looking forward to hearing from you. Thanks in advance. François.

This morning the add-on 'Search By Image' has ceased working. I use it daily, it worked yesterday, and so far as I know there have been no updates to FF or SBI or Windows.

To test I tried removing SBI and re-adding it, and disabling Malwarebytes.

I disabled SBI and installed "Image Search Options". ISO works, though I prefer SBI.

Win11, FF is now 119.0, but it auto-updated when I went to check so I do not know what it was when the problem began this morning. I have not restarted, I have too many tabs open at the moment.

This is also happening to a different PC that is Win10/FF, but never had Malwarebytes installed. SBI still does not work after restarting FF v119.0 in Win10.

Any ideas on how to diagnose this?

Hi there, Last night I installed some new hardware into my PC, new motherboard and CPU for example. After that, I booted up the PC, everything worked completely fine and I was able to listen to Youtube / Twitch / Spotify etc. through Firefox.

This morning I boot up the PC, everything still works perfectly and I have audio coming from all other sources EXCEPT for Firefox. I have browsed every forum already but can not find anything that relates to me. I can't set my output device, since Firefox doesn't show up in the volume mixer. The tabs aren't muted. I have restarted Audiosrv and Windows Explorer several times. I have re-installed Firefox twice. I have tried booting it in safemode. All of the above hasn't resulted in a single second of audio. I am at a loss.

Kind regards, Siem Hoefnagels

Hello,

How come that we are in 2023 and we still do not have major features like Chrome's Profiles or Orion Browser's Profiles.

For example, Orion Browser creates an app per profile and this allows MacOS users to customize each app with a different icon. This seems small but on a taskbar we can differentiate the instances faster.

Why is that the best option for managing profiles in Firefox is the Firefox Profile Switcher, a third-party tool supported by a community member?

Will this ever be addressed? Firefox is better than the others in so many things but, for example, even Safari implemented Profiles now.

To be clear: containers are NOT the same thing as profiles and profiles still have an usage. For example, my work profile has no syncs, different extensions and stricter configurations than my personal profile and this cannot be done with containers.

Thank you!

To identify myself I had to scan a qr code on a website using my phone. This used to work in firefox but it doesn't anymore. It still works in edge. I'm using firefox 119.0.1 x64 on windows 11 home 22H2. How can I fix this?

my electronic health record is freezing using Firefox on 2 different computers in 2 different locations. Internet speed 45 mbps at 1 location and 900 mbps at another. Able to use it on chrome.

Was getting some crash reports....now have a black bar on top of new tabs...it finally scrolls when you are halfway down the page. any help would be appreciated.

Firefox not responding to general websites on the web (Ex: Amazon.com, etc.). I have several Mozilla-recommended security extensions that may be working against my firefox connecting to these general-in-nature websites.
