Chrome seamlessly harmonizes with the PowerToys FancyZones feature in Windows 11. In Chrome, I can drag a tab out of a browser window, and instantly snap it into a FancyZone. I can also quickly arrange multiple separate Chrome windows into FancyZones without issue.

Firefox's interaction with FancyZones is not good. When I drag a tab out of a window, it doesn't allow me to snap it into a FancyZone. I first need to release left click, allowing the tab's new window to appear, then I can snap that window into a FancyZone.

The biggest occurs when I have multiple Firefox windows open and snap one of them into a FancyZone. Often, one of the open Firefox windows will spontaneously shrink itself in size. When I try to manually resize the window back to normal, it shrinks further and further, until it is an invisible sliver. The only solution when this occurs is to fully restart Firefox.

It seems strange that Firefox has such poor compatibility with FancyZones, which is growing in popularity along with other productivity tools in PowerToys. Wondering if anyone else has experienced these issues, if there is any workaround, or if there is a fix being worked on.

Recently Firefox has been randomly crashing the past 3 weeks multiple times, Is anyone else having this odd issue ? I'll be watching a stream or youtube video and bam out of no where the Browser goes black for like 20 or 30 seconds then crashes. I sent in about 3 crash reports and wondering if the Firefox team is aware of this issue.

Starting this morning I am no longer able to access my banking site with Firefox. My current version of FF is 133.0.3 for 64 bit Windows 11. I could access it yesterday. Looking at the support on this, I see that this has been a problem with Firefox for quite a while. I can access my bank with Chrome (although I don't trust Chrome) so why not FF? I haven't changed any settings. What set this blockage off and how can it be eliminated. If a setting needs to be changed, please tell me what it is and how to fix it.

I did some googling first and it seems to be an on and off issue mozilla has had with years. Anyway, whenever I play a video (be it youtube, twitter, instagram, even gifs on twitter actually) the video will often mess up and become a chaotic jumbled garbled up mess of green with junk artifacts over the video. The audio will play fine. It's like watching a scrambled TV station from a 90s bootleg cablebox, but green.

This issue doesn't exist in any of my other browsers.

I'd love to continue supporting Firefox instead of Chrome, but this is a persistent issue across the entire internet, so it's kinda obvious I need to stop using Firefox until this is patched. 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;

}`

Hello, I've got the french version of Thunderbird on my laptop. I want to have it now on my smartphone Android. But impossible to find the function "move to mobile" in the parameterss... Please help me !

Hi,

I'm on OS Windows 11 and the latest version of FF (133). I also use NordVPN; I can access the web via Edge and Chrome with VPN, but for the last month, it doesn't work with FF. What could be the problem?

Suddenly Firefox is downloading my downloads to google drive. Why? I want them in my download directory, but changing the options in Settings/General/Download makes no difference. It is set to ask where a file should go, but does not. It is set to ask whether to open or save a file and it does not!

How can I get google drive out of this and save them to my desktop again?

I have an mp4 (h264 AAC) video of 37MB which plays acceptably from my website in Safari, Chrome and Edge, but when played in Firefox (my default browser) the sound and picture synch is significantly seperated. When the video is compressed to 26MB it suffers some expected loss of sound quality but plays with near perfect lip synch. What is the issue with playback ?

My laptop (a Lenovo Ideapad220s) did an automatic Windows 11 update (I believe it was the 2H24 update). After that Firefox (version 133, 64 bit) would only open with the message "Gah. Your tab just crashed". Nothing I tried has worked, not any of the remedies found in support pages. I somehow did a Firefox software update and it shows as a separate icon and has not migrated any of the passwords and bookmarks I had in the software version that keeps crashing (my default browser). Trying to get access to the encrypted passwords to the many sites I've got with Firefox I opened the browser in troubleshooting mode. In this mode I have access to all the passwords saved over time, and the browser seems to work fine.

Any suggestions on what I need to fix or if this is related to the Windows update? I'd like not to have to go through the two-step process to use the browser.

Thanks!

My facebook account keeps getting double logins and ip4 logins rather than ip6 addresses. I think my ex-employer has installed a certificate into firefox on my laptop. I know absolutely nothing about certificates and have never knowingly installed one into my firefox web browser. But after looking I seem to have a certificate, is this certificate something that is allowing someone else access to what I view on my browser or allowing access to my cookies? Would users normally have their own firefox user certificate installed that they are unable to remove with a year on the date? I have added 2 screenshots. Hopefully someone can help Best regards David

Although listed as one of the options for default language, the current version of Firefox, which is my default browser, does not accept Brazilian Portuguese as the default language. It only accepts the Portuguese version, from Portugal which, to me, who speak Brazilian Portuguese, with all due respect, is a pain in the butt. I have tried, dozens of times, to delete the Portuguese version and set the Brazilian version as the default language. It works until I shut down the computer. The next time I turn on the computer, to my eternal dismay, Firefox cancels my previous language setting and reverts itself to the damn Portuguese version, which I dislike to the extreme.So I am, hereby, taking the issue to you with high hopes that this abdomally be straightened out once and forever. Many heartfelt thanks and wishing you sucess. Damião

Hello,

 An update or two (maybe more?) ago, the plus sign with which we add shortcuts to the Firefox browser home page/new tab page disappeared, so now we can no longer add shortcuts on the home page/new tab page.  Please help.  I am running Firefox Version 129.0.2 (64-bit) on a Windows 11 Pro 64-bit if that makes any difference.  Thanks.

We use Firefox ESR in our environment today, Is it possible to have a policy that would display "update required" message to end-users, or have it automatically update without users opening the browsers.

Hello. The latest update of FireFox 129.0.2 still has intermittent crashes. Sometimes I can't access my Google searches or links in emails don't work, then it works, then it starts to malfunction again. I have to restart my PC. Could you release a patch that works as well as before FireFox 129.0? On the other hand, Canal+ works perfectly Thanks. Kind regards.
