Firefox Community Forum

Earlier today I was trying to watch Prime video and I kept getting an error saying that Firefox wasn't updated (which it was). I looked up some solutions, one of which suggested turning the DRM setting off and then back on. That was a mistake, because after that, any time I opened Prime or netflix, the error I got was "Firefox is installing components needed to play the audio or video on this page. Please try again later. "

Then, I looked that up and found out that my Widevine was just not installing. So, I found an alternative way to manually install it, which shows that it is installed in the Add-ons Manager, but I keep getting that error and nothing works. Prior to this my Netflix was still fine and working.

I've tried a few other things including closing firefox, refreshing firefox from the troubleshoot settings, and restarting my computer.

I am out of ideas, and I wanted to see if anyone can help me before I have to jump ship to another browser.

I seem only to have issues installing the Nightly build. I have successfully installed Firefox's main, beta, and dev builds.

I received the following error/message when installing it. (see attached images)

This issue occurred on a fresh install of Windows 10 directly from Microsoft's image creation tool. I upgraded to Windows 11 and experienced the same behavior. I used the tool Revo Uninstaller to uninstall previous versions of FF completely and used the tool to clean and purge any leftover registry entries and directories. No errors or entries in Event viewer.

Anybody run into this issue?

Hello,

I'm trying to update to firefox version 133.0. My O.S. is Ubuntu 20.04. I've untarred the tarball to ~/firefox/firefox-133.0/.

If I startup the new firefox, I receive the following error message: "libxul.so, undefined symbol: gdk_window_show_menu".

I also tried firefox version 120.0, except the result was the same.

How can I fix this?

thanks.

A friendly hello to whomever is kind enough to read this! Your help is greatly appreciated!

The latest update caused an edit I made to my Profile's userChrome.css file to be nullified. Now there's huge bar where the tabs toolbar used to be, and apparently it's not the title bar, as when I activate the title bar in "Customize Toolbar," this huge gets replaced by the actual toolbar.

I've attached my css code below for inspection. It used to work perfectly, but after the last update (133.0) it's no longer working. What can I do to fix this and have it like I had it prior to the latest update (133.0)?

userChrome.css File: `#main-window[tabsintitlebar="true"]:not([extradragspace="true"]) #TabsToolbar > .toolbar-items {

 opacity: 0;
 pointer-events: none;

}

1. main-window:not([tabsintitlebar="true"]) #TabsToolbar {

   visibility: collapse !important;

}

1. main-window[tabsintitlebar="true"]:not([extradragspace="true"]) #TabsToolbar .titlebar-spacer {

       border-inline-end: none;

}

/* Adding empty space for buttons */

1. nav-bar {

margin-right:140px; }

/* 15px for dragging whole window by mouse*/

1. titlebar {

appearance: none !important; height: 15px; }

/* Fix for main menu calling by Alt button */

1. titlebar > #toolbar-menubar {

margin-top: 10px; }

/* Move minimize/restore/close buttons to empty space */

1. TabsToolbar > .titlebar-buttonbox-container {

display: block; position: absolute; top: 17px; right: 1px; }

1. sidebar-box {

 min-width: 250px !important;

}`

Team, I am a longtime user and supporter of FF. I can't tell you how much I love the the layout of Firefox on Windows in v. 133 with the vertical tabs. Just as important is the fantastic, new font rendering. Thank you so much. I used to make multiple adjustments to the font in about:config when I installed FF on Windows. Now, the fonts look fantastic out of the box. Great job, team!

For the past month or two, at random times when I open Firefox, I see a message stating, "Looks like you reinstalled Firefox." To be clear I have not uninstalled Firefox in any instance where this message has been displayed.

When this happens, I’m unable to browse the web. To resolve the issue, I have to remove the uBlock Origin extension and reinstall it. Once I’ve done that, browsing returns to normal. However, I then need to reconfigure my filters and adjust settings within FireFox

I’ve tried uninstalling and reinstalling Firefox to see if that would prevent this issue, but it hasn’t worked.

This problem is specific to my PC—it has never occurred on my MacBook.

Any assistance in understanding why this happens and how to prevent it would be greatly appreciated.

Thank you.

In Firefox add-ons, the 'Recent Updates' section can be accessed through the cog wheel icon. How many days of updates does it cover? I'm asking because I don't want to miss any important updates. Thanks!

after updating windows i got this message "Your Computer must be restarted to complete a previous upgrade of firefox. Do you want to reboot now?" when i restart i get the same message

I am a survivor of a brain injury and many things do not connect and I am not a tech person. I don't even understand the choices there are for me to ask a question! I cannot use any FAQ's or topics for help because I will not remember them when I need to use them. I need to know how to download to a USB drive; step by step directions/instructions do not help me. Is there a solution? I would like to purchase sewing machine embroidery designs online and then download them to a USB drive to insert into my sewing machine in another building. Microsoft has been no help with this. Any help would be very much appreciated and thank you.

How can I roll back or uninstall this latest update? I'm suddenly stuck with this big stupid empty sidebar and it's an eyesore and distracting and I hate it. Almost worth going back to Edge for it. I want it gone. Nobody wants bezels on their phones/devices, who the hell thought it was a good idea to take up more window on their web browser!?

A problem with an x.0 version? I've been using FF from "source code" for years on Debian Linux, but this is the first time such an update is failing after the most recent update to v133.0, as illustrated in attached image. How can I now update to the fix for this problem, please?
