Hello! Can you help me sort out a little problem? I am reaching out to seek assistance with a specific issue I am encountering in the Firefox browser.

In my previous browser, when opening new tabs, they were considered active even if I did not immediately switch to them. This behavior allowed me to open multiple tabs, for example, by using the mouse wheel to open several videos from the main YouTube page. Subsequently, when closing the main page, the videos would be available in the order they were opened, facilitating a seamless viewing experience.

Upon transitioning to Firefox, I have attempted to configure the browser to replicate this behavior using the Sidebery extension. However, even with the extension, new tabs are not recognized as active unless I explicitly switch to them, making it challenging to maintain the desired tab activation order.

I have explored various settings and experimented with the Sidebery extension but have not been successful in achieving the desired result. In contrast, the Yandex browser, with the "Switch to the previous active tab when closing a tab" option enabled, behaves in the manner I am accustomed to.

Could you please provide guidance on how I can configure Firefox to consider new tabs active immediately upon opening, regardless of whether I switch to them immediately?

I added pictures to make it clearer what I'm talking about.

Thank you for your time and assistance.

I switched from windows 10 to 11 and to a new laptop. Here in my new laptop Asus tuf 15 ,even though it has better RAM , internet connection, cache memory, cores the FIREFOX doesnot function properly. It's extremly laggy specially when I use YOURUBE . In my earlier HP laptop with 8 GB ram I could use 10-15 tabs at one time .It would still not lag . It could do web development at the same time I could watch youtube tutorials. But now I barely open 4-5 tabs the youtube starts freezing up to the extent that I really get frustrated. Please so something or I will have to switch to BRAVE browser or something.

Hi Mozilla Suport teams, i am currently using the mozilla for the developer version and the app runs flawlessly, and i love it. But i have some suggestion for the developer at mozilla to make a tab that can group the tab into a fresh tab like the google chrome has, and since i open so many tab in this browser, i would absolutely love it where the feature of grouping tab is available for me, so i can group them in name and leave it there, rahter than open up more than 10+ tabs in a window. Thank you so much

When watching a video on YouTube, the sound suddenly stopped playing. Currently, sounds in video and audio are not played on all sites.

The problem is only in the browser. Audio and video files are perfectly reproduced by the VLC player. There is also sound in the Chrome and Firefox ESR browser.

My actions. 1. Disabled all extensions 2. Clearing history and deleting all cookies

My browser - Firefox Developer edition, version 123.0b9 OS - Debian 12

P.S. I have been using the developer edition for many years. It seems to me more convenient and faster compared to regular Firefox. I really don’t want to delete the customized browser.

I need help with audio in browser...

Many thanks!

I do not want my searches to be reflected in the address bar. I believe in prior versions of Firefox there was a checkbox to delete that provision. I'm using Firefox 123.0 64-bit with Windows 10 and have been through the setting and more tools areas but found no way to remove that function. I did try the about:config suggestions but still have no joy.

This is a recent failure (this week), that occured without any changes on my own account to Firefox developer version 121.0b2(64-bits)

I had to install google chrome to overcome this problem. Chrome has no issues with microsoft authentication.

Please solve as soon as possible, otherwise I will be switching to another browser.

I'm having an issue that seems to Lock up YouTube on Firefox.

I'm trying to get back into using Firefox but I'm having a persistent issue in both FF Mainline and even in FF Beta 119.

If i play a Video on YT then switch tab to do something else then go back to YT it lock up the video window. I do not have this happen on Chrome or Edge.

I have tried refreshing the browser and still have this issue.

I'm on Firefox Developer Edition 119.0b9 (32-bit) and Windows 11 Pro 22H2 but I've been experiencing this problem a lot longer ago even before upgrading to Windows 11. The first thing I open in my computer is Firefox, it gets the window itself quickly but the page stays blank with the gray loading dot going right and left for nearly 10 minutes before the page loads and Firefox works normally. I don't experience any issues while browsing the internet after that long loading but it's really annoying especially when I'm in a hurry and I don't have 10 minutes to stare at a blank page.

I am running Firefox Developer Edition (123.0b1) on Windows 11 and every time I start Firefox it maximises and then resizes to a set size with the maximise button set to restore size mode (I.e. the window thinks it is maximised). I have followed the steps detailed for this question: https://support.mozilla.org/en-US/questions/1411093 however that does not resolve my issue. This has only started recently after I turned the laptop into a tablet and back again. Once I "restore" the window and then I maximise the window it works as expected. However it is very annoying. Also if I start another instance of Firefox this new instance does not exhibit the same behavior.


Computer: HP Envy OS: Windows 11 with all current updates and as far as I can tell AI is turned off using a group policy.

I switched to Firefox DE because I wasn't able to install 3rd party extensions. Just now, my middle click isn't working. I can't use the middle click to open/close tabs and to open links in a new tab. I checked my settings, tried a new profile, nothing works except in normal Firefox, the middle mouse does work, but I don't want to switch to that. My middle click also works in Edge and other apps, but please fix this issue as soon as possible. Thank you.


PS. Please add biometrics to Firefox, like how Google did with Chrome.
