Hello,

Recently Firefox tends to start autoplaying a YouTube video if I am on the tab.

Before it would not play the video if i am on the tab unless I physically press play.

It still works if I open a YouTube video in a tab that is not active, it will not autoplay, but as soon as I hover over and click on that tab it will start playing, however I do not want this to happen, I want it to pretty much always be autoplay blocked regardless if tab is active or not and I want to physically press play in order for it to start.

How to revert it to that state?

My block audio and video setting in firefox is already turned on, not sure what to do, pretty sure I did nothing on my end.

Right now I have to use extension called "disable autoplay" just to get by.

Thanks guys!

Hello,

I just recently went from Brave browser back to the old days on Firefox but there is one thing that I miss and I cant find any information anywhere about that when I opened new tabs on Brave it didnt switch to the new tab directly. Sometimes I wanna open alot of links from a page but its a real hazzle here when I need to go back to the old tab again everytime. Is there a setting for that anywhere?

Kind regards

Hi - I need some help restoring the 100+ open tabs that are in Computer1, and open them AS-IS in Computer2.

To help you understand my story......Computer1 is main machine, and I had over 100 tabs opened in there. I would like to transfer ALL of the open tabs to Computer2, before re-partitioning the C Drive in Computer1.

The problem is, my Computer1's Windows 10 is giving me problems at the moment, so I can not get into the computer by logging in. No recovery or diagnosis method will do the trick, so I will have to reinstall a fresh copy of Windows into Computer1. Besides, the computer was troubling me for having only ~50 MB available space in the C Drive (I have multiple partitions in my hard drive).

For now, I have removed the hard drive from Computer1, attached it in Computer2, and have access to the data in the various Computer1's drives.

I read many articles here in the Support Mozilla help site to restore the 100+ open tabs from Computer1, into Computer 2, but it is not working for me. I even tried copying the entire "sessionstore-backups" folder from Computer1's location, and replacing the same folder in Computer2's location.

Maybe I have to do more than just copying the "sessionstore-backups" folder, like do something additional through FireFox options??

Any help would be appreciated.

And here is the location of the "sessionstore-backups" folder in both computers:

Computer1 K:\Users\Team Umizoomi\AppData\Roaming\Mozilla\Firefox\Profiles\jrvowkxo.default\sessionstore-backups

Computer2 C:\Users\einstein jr\AppData\Roaming\Mozilla\Firefox\Profiles\x9z76c15.default-release-1\sessionstore-backups

if i have for example 4 tabs open i will also have 4 windows that all share the same tabs. i have tried using "about:config" and inputting "browser.tabs.allowTabDetach" and setting it to false and it doesnt help. what can i do to get opening a new tab to stay on the same window

In the new version of the Developer Edition the options "close tabs to the right" and "close other tabs" are in a sub-menu named "Close Multiple Tabs" inside the context menu. Is there's a way to change this so that they will appear directly in the main context menu? I use "close tabs to the right" often and I find this very annoying.

I restarted firefox today, and now I have the following behavior: I have a window with many tabs open, enough that I have the little '<' and '>' scroll buttons in the field. Whenever I move the mouse pointer into the tab area (including the scroll buttons, but not the '+' (new tab) button to the right), unless I am actively clicking, the tabs start scrolling rightward until only the rightmost set of tabs are visible. The window being viewed does not change. I can use the 'v' tab selector to the right, and it will select the chosen tab and make that visible in the window, and make the selected tab visible in the tab bar, but when I again move the pointer into the tab area, it starts scrolling to the right. Similarly, I can click on the '<' scroll left button, or double or triple click on it, and it will scroll the tabs leftward; but immediately after completing the action, the tabs will scroll rightward to the end again.

It seems my problem is the same one as in this thread but there was no solution given there (the problem persists after restarting Firefox in troubleshooting mode). I see the same behavior as that poster with the tooltips in the tab bar, but drop-down menus such as on this submission page seem to be working normally for me.

I'm running version 118.02.2 (64-bit) of Firefox on Windows 12. I *always* have the 'Open previous windows and tabs' checked. Starting yesterday, Firefox opens with nothing other than a blank page. Luckily for me, this has happened in the past and I have a Bookmarks Menu folder with my default tabs saved. Even so, it's still frustrating.

I'm on the latest version of Firefox, 106.1, and I'm missing the Firefox View button on my MacBook Pro 13". It is showing on my Mac Mini M1, and both are logged in and syncing properly using my Firefox account.

When I type in about:firefoxview on my MacBook Pro in the URL bar, I see the page but noticed it says "New colorways are on the way" on the right. On my Mac Mini, I see the "Independent Voices" text and an option to "Try colorways".

Bug? Some weird setting on my MacBook? Both are running macOS Monterey, 12.6.

I stupidly upgraded to the worst system in the world, Windows 11, and the silly animations caused serious strain on my device. I disabled the animation effects in settings, but now when I use Firefox as usual, the loading page icon animation has become a static hourglass icon, which is unfriendly. How can I enable the loading page icon animation while keeping the system animation effects turned off?

In short, "Open previous windows and tabs" is no longer working. I'm using version 111.0 (64-bit).

I have done the following: 1. Troubleshooting mode 2. Removed or disabled all my extensions 3. Refresh Firefox - twice! 4. Disconnect sync across my two laptops

Still, nothing is fixing the issue. My previous windows and tabs are not being restored.

Help, please!

Firefox updated and now my tabs are above the address bar, I hate it. I have went through all the information I could and created a new chrome folder, downloaded the css and changed user preferences but it sets the tabs to the bottom of the screen not just below the address bar. I think I need a different set of code for the css but cant find a copy. Does anyone know what to do?

When you open a link from the sidebar while holding ctrl, firefox opens it in a new tab and switches to it immediately; whereas when you click a link from a webpage with ctrl, it does not switch to the new tab (unless you hold shift as well, or check "When you open a link, image or media in a new tab, switch to it immediately" in settings > general > tabs). I would like if firefox does not automatically switch to opened links from the sidebar (history, bookmark, etc.), when I open them with ctrl? (I know I can hold shift to do that, but I was wondering if there might be a preference in about:config to change the reverse this behaviour for sidebars)

Thanks, Ibr.

Hi!

Let's start by saying that I love Firefox, that I use it as my primary browser everywhere and I love that is not based on chromium. However, for reasons to me unknown is missing a very important feature (natively at least): tab grouping. This feature is extremely simple to implement and in today life, where in most jobs (I'm a researcher) you have to deal with a tons of tabs opened in your browser, being able to effectively organize them is a must.

My question is: has Firefox the intention to implement (again) this feature? Will this happen soon?

I'm really trying my best to not switch to a competitor browser and I really want to support Firefox and hope that it gains more and more users. But for this to happen it really needs to be on par with time. How come every other popular browser has a very good tab grouping feature and Firefox doesn't?

Please, let me know if there's a chance to see this feature implemented in reasonable times. Sooner or later, you will probably have to do that reagardless.

Wish you the best, A.

Till version 112 I used this in my userChrome.css to get back the close buttons on tabs, but only when I hover over them (active or inactive tabs): .tab-close-button{ display: none } .tabbrowser-tab:not([pinned]):hover .tab-close-button{

   display: -moz-box !important

}

But now with version 113.0.1 it doesn't work at all and no X appears when I hover over my tabs.

I tried adding #tabbrowser-tabs[closebuttons="activetab"] on top of the previous code, but it made the X appear all the time.

How could I update this code so I get the desired result only when I hover over a tab?

I have two computers, one for personal use and one for business. Somehow the tabs between the two computers are being shared and I cannot disable it. Both browsers are signed into different Firefox accounts, Sync is turned off on both, and there are no connected devices. Yet despite that, when I go to one computer, it pops up a Firefox icon (see attached) in the taskbar that lets me open the tab open on the other computer. This is incredibly frustrating and Firefox should not automatically share this information, and should not make it so difficult to disable.

How do I enable container tabs? The option to open a new link in a container tab has disappeared and the prompt doesn't show up when I long press the new tab button either

On all my new tabs which open with "Recommended by Pocket" items, the "Sponsored by ..." items are in German. All my language settings are "en-amer".?? All the other items are in English.

Same as this question, but the answer is outdated: https://support.mozilla.org/en-US/questions/839240

Is there a way to do this in the about:config page?

There is an answer about holding `Alt`, but that is a workaround.

I'm having a problem sharing websites with others via, for instance, Signal. Telegram, WhatsApp or a social medium. There used to be a share button in the toolbar, but this I cannot find anymore. At some time there were also the three dots in the address bar that dropped down a menu for the page, which included a 'share' option. These dots seem to have vanished. Also I vaguely remember that the "share" function was also in he tab context menu once upon a time. However dropping down that menu does not reveal any "share" function presently. Then there was, if I remember correctly, the possibility to click the File menu at the top of the screen and then click on the Share menu item over there. But also there the "share" function seems to have vanished. I also looked in the settings menu, to find if there is a setting there which switches on or off the sharing function. I could not find such a setting. In short, it seems that I am horribly overlooking the "share" function. Please help me find it. Thanks. (Firefox 112 for Manjaro Linux)
