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;

}`

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!

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.

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?

On the newest firefox update on Windows PC My PDF reading has been not displaying PDFs correctly on Firefox I tested on other PDF views and they work as normal (All images are normally white with black text PDFs) Sometimes it displays nothing at all (as seen in Image 1) Some pages will display correctly but the rest won't (as seen in Image 2) Some pages will display text but strangely (as seen in Image 3) It does flash white sometimes while scrolling but it still doesn't show text

I'm root on a bunch of Linux machines and I'd like to write and add addons to setup some security-related policies. Writing the addons is not a problem, the problem is how I can make sure that they're installed for all users on the machine and cannot be disabled.

This is Ubuntu, which currently distributes Firefox as snap, but if necessary, I can probably use more classical Debian packages instead.

Hi All, Apologies if I've missed something, but I can't find an answer anywhere. I've got a fresh install of Firefox version 133 running on Windows 10, and I can't seem to install any add-ons. When I click the install button from the add-on's page, it just sits there with the loading animation and seemingly does nothing for several minutes. Attempting to right-click on the download button, "save link as", and hitting "install add-on from file" using that saved link as another user suggested from a similar problem does nothing at all; there's no feedback whatsoever. The add-on I've been trying to install is U-Block Origin, but I've tried this with other add-ons to the same results. The only other thing I've tried is installing one of the recommended add-ons from the add-on page directly, Privacy Badger specifically. This causes an actual window to pop up telling me Firefox is verifying the add-on, but nothing happens past this point. It just sits there, eternally attempting to verify the add-on with no progress ever made, and no error message ever spitting out. I haven't found anyone else with this exact problem. Hopefully I'm missing something obvious and I can feel really silly about the whole thing soon. Thanks much!

All the Best, G.B.Bari
