Despite Tab Groups not yet being "rolled out" in Australia, I am wondering if "Container Tabs" will still be Supported (in the following ways):

1. Will Container Tabs still be able to be used effectively in concurrence with Tab Groups? 2. Is it planned that Tab Groups is being developed to replace Container Tabs? 3. If one will be able to use Container Tabs concurrently with Tab Groups, can different Container Tabs Types be split over different Tab Groups? 4. Is it planned that Tab Groups will supersede Container Tabs in terms of Protection, Privacy, etc.....? 5. Will Tab Groups be able to be put to sleep/hibernate in order that Firefox "speed/memory" is not effected?

Whilst on the subject of Tab Groups and Container Tabs: 6. Up until a few updates ago, when the mouse was hovered over a Container Tab, a dialogue box would indicate: the Tab Subject, Site Identity and Container Tab Type. Please bring back the Container Tab Type when the mouse hovers over a Container Tab..! 7. When this (Valuable) information was ceased, the only way to get similar information - namely the Container Tab Type - has been to use the: List all tabs icon {tab icon 2} at the Right hand end of the toolbar. It is a blessing that this was not changed, but still a bit of a nuisance to check them both! Why is this an issue you may well ask? - I am sure I am not the only Firefox user (Forever) - with memory decline!

Thanx

Hi all,

I'm an English speaker in Germany, and I'm trying to add amazon.de as a search shortcut, using the official steps (right click on address bar, choose 'add Amazon').

However, I'm getting the following error: Firefox could not download the search plugin from: https://d2lo25i6d3q8zm.cloudfront.net/browser-plugins/AmazonSearchSuggestionsOSD.Firefox.xml

I've seen similar calls for help that seem to stretch back years, but alas they appear to have had slightly different symptoms/solutions that don't seem to apply to my situation.

Cheers.

After updating to v 133.0, when maximizing Firefox (not F11 fullscreen), a taskbar that is set to "auto-hide" will no longer unhide when mousing to the bottom of the screen. This did not occur with the previous version (132.0.2).

This behavior is also unaffected by the "devtools.toolbox.alwaysOnTop" setting in about:config as i've tried switching from the default "true" to "false".

Update: Still persists in 136.0.2

My YouTube homepage is blank when I visit using Firefox (see attached screenshot). Here is a list of all of the fixes I have tried:

-Disabling all extensions and turning off Enhanced Tracking Protection (at the same time) -Clearing cache -Clicking 'forget this site' on YouTube in my browser history -Restarting my PC/Firefox -Refreshing Firefox profile (this worked, but the issue returned after an hour) -Changing my system theme to light mode -Launching Firefox in troubleshoot mode -Logging in on an incognito window (with the same result) -Probably some other things I'm missing (I tried pretty much every result I could find from looking up 'YouTube homepage is blank' and 'YouTube homepage not loading).

The issue only occurs on Firefox and only after I log in to YouTube. This has never occurred before. I checked to make sure my Firefox and YouTube settings are the same as they've always been.

YouTube videos load fine as long as I paste the direct link into the URL bar, but ONLY the video (no comments, recommended videos, likes/dislikes, description, etc...) and I can't take it out of theatre mode nor fullscreen it (fullscreening it just removes the top bar of the browser--the video itself still has black bars on the sides).

Sometimes when I reload the page, I see the following at the end of the URL: &ThemeRefresh=1. I don't know if that means anything.

I am using the Firefox app on Windows 11. I am not using a VPN. This issue is specific to YouTube and YouTube only.

Any help would be greatly appreciated. Thanks!

i just upgraded firefox for Mac OS to 115.23.0esr (64-bit) and now I cannot log in to my bank account from this desktop. Safari works on the iPhone but I NEED FIREFOX ON THE DESKTOP IMAC (Sierra 10.12.6) There seems to be NO INFORMATION ON YOUR "ASK A QUESTION" PAGE ABOUT THE UPDATE

Today was the second time in two weeks I have lost every open tab in Firefox. Previous to this, this problem has not occurred in at least 5 years. What is going on? To utilize data from multiple sites takes a long time to relocate sites and this is becoming unacceptable. Firefox updates are better than this. Thank you for your help.

I have an Arch Linux installation with Plasma desktop. Software is always kept up-to-date. Sometime recently, Mozilla apps, Firefox nor Thunderbird, will no longer print, neither to pdf nor to network printer. These always worked before. Now, if even "print preview" is invoked, the dialog opens as a blank sub window with only the word "Print" in upper right, and at left center is "Preparing Preview with rotating time delay wheel, which never resolves. All other apps, including other browsers and mail handlers, will print without issue. I've tried the obvious checks with no success. Where could be the problem? Is there a helper app shared by Firefox and Thunderbird that could be the issue? The only potential remedy I have not yet tried is complete removal of both Firefox and Thunderbird, as that would cause re-configuration issues for both. It's necessary to press <ESC> to terminate the print window when it fails to respond. Screenshot attached...

Greetings...

I am a frequent user of multiple tabs whenever I use Firefox. As a result, the new Tab Groups feature interests me, primarily if it will help my to organize and manage my multiple open tabs. Initially, I have the following specific questions.

Q: Is there a maximum quantity of tabs that a Tab Group can contain?

Q: Is there a maximum quantity of Tab Groups that can be open at the same time?

Q: Does the use of one or more Tab Group negatively affect the performance of my web browser?

Q: Can a Tab Group be bookmarked? (Periodically, I need to bookmark a group of open tabs and I am currently able to do so by selecting all of the tabs then bookmarking them as a set.)

Q: Does the new Tab Groups feature represent a way to reduce the number of open tabs that appear at the top of my web browser - basically, a way for multiple open tabs to occupy a smaller space versus scrolling them across the top of my web browser?

Thank you very much for your feedback! Take care...

Dear Firefox Team,

I hope this message finds you well. I would like to suggest a small but useful enhancement to the Firefox interface that I believe would improve user experience and accessibility.

Currently, in the "Customize Sidebar" section, the available tools are limited to a few items such as AI Chat, Tabs from Other Devices, History, and Bookmarks. I believe it would be very helpful to include "Downloads" as an additional sidebar tool.

This would allow users to quickly access their recent downloads without needing to go through the menu or use shortcuts. It adds convenience and aligns well with the purpose of the sidebar — offering quick access to frequently used features.

Thank you for your time and for continuously improving Firefox. I look forward to seeing future updates! Warm regards, Julabeeb a firefox user, developer, and contributor

i write an email and it automatically goes to the outbox,.... but it never is sent. my sense is that it's trying to send emails via another browser... not firefox and it just locks it up.

Youtube is nonfunctional on firefox as of April 29 2025. It was all working fine last night, then I woke up to no youtube. It loads the website as a blank screen. Videos can be accessed by going directly to their URL, but no recommendeds load in, no comments section, even the title and channel information is unavailable. I would say none of the buttons work, but there are no buttons to test. It works fine in Chrome still. I know it's not my extensions because I tried removing them all, and it didn't fix it. I know it's not my cache/cookies, because I cleared that too and it didn't fix it. I know it's not on Youtube's end, because it works fine in Chrome. I know it's not an update issue, because I updated my browser and it didn't fix it. Please. I want to be able to use youtube in firefox. Please help me fix this thing. I have attached photos, but I suspect they'll be more demonstrative of the problem than useful for troubleshooting.

When I open Firefox it opens a maximized window with tabs, then it opens a minimized with a single tab, then it reopens a maximized window with all session tabs. Each window displays in succession, one window at a time.

I'm on desktop using Windows 11.

I just read a post saying this behavior was caused by the resist fingerprinting feature. Can someone explain how that causes the repeated opening of browser window 3 times. Is there a way to retain the anti-fingerprinting behavior w/o the multiple window opening behavior?

Every document like the below one does not display in firefox esr 115:

https://support.hpe.com/hpesc/public/docDisplay?docId=c01081836&docLocale=en_US

I get an empty pdf viewer frame. Also the debugger shows the following error;

Uncaught TypeError: Promise.withResolvers is not a function

Is there some way to overcome this problem? a future release of firefox esr?

We want to use Firefox on a locked down system. Using the -kiosk command line argument gets us most of the way there. But they still have access to the devtools when they hit F12. It appears there are ways to disable devtools after the browser has been started. How can we disable the devtools before the browser is opened and without registry changes?

Hello When i download files it has started to put UTF-8 before the name of the file ? Why is that ? Because it doesn't do it if i try it in another browser.
