Firefox Support Forum

I want to keep browser open after closing last tab. I changed the boolean parameter "browser. tabs. closeWindowWithLastTab" to "false" but the browser still closes with closing of last tab.

What else is required ?

Do Firefox menus appear differently in Windows 10 than they do in Windows 7?

In Windows 7, I see the normal system menus - square corners, light blue menu item highlights, 3D column line on the left, dark drop shadow below and to the right of the menu.

In Windows 10 I notice differences - gray-highlighted menu items, rounded corners, no drop shadow, etc.

I'm not using any code to style the menus.

Please see attached images.

Thanks to all who respond.

Sync just does NOT work. I installed FF on my Mac brand new and fresh... brand new machine. Signed into Sync. NOTHING. After 6-7 HOURS... nothing. It just gets NOTHING AT ALL from my Windows Desktop.

I've signed out of ALL Firefox/Mozilla sync sessions... signed in clean- all browsers are up to date. And the about:sync-log page shows a LONG streak of errors... NON STOP ERRORS.

Why?! Why can't we just sync extensions to install and bookmarks across machines? How is this that hard for Mozilla?!

Day after day and attempt after attempt of failures for a basic function of the browser.

Here is the text of the latest log and showing constant connection errors- mind you NOTHING is breaking on my internet as I'm often streaming things and watching stuff while surfing, or others in the house are. Our connection, and Firefox getting online, are all working fine. I am at a loss. I don't understand how this is so terribly broken out of the box that you can't just sign in and let it talk to their servers. I know Google has billions behind Chrome, but this shouldn't be so 1990's bad by comparison to Chrome sync.

On my iMac 2017, up-to-date OS, Firefox won't load YouTube. It only shows the spaces for videos. Attached is a screen shot with the console info, but I don't know what it's telling me. However, on my MacBook YouTube works fine, so maybe I have a setting wrong on the iMac? Meanwhile, I just switch to Safari. Thanks for any help

I use google as my default firefox home page on my HP laptop. recently a second tab opens at the same time. "how to set the home page" --I've tried closing it and restarting the laptop, but it continues to pop up every time I open firefox as a 2nd tab. I am/was happy with my homepage opening to google. How can I get rid of this second tab. thanks

Needed to look through my April history (pages looked at) in the Library. I had APRIL history up, ready to look through it. I tried to delete one page and it DELETED the whole MONTH. How do i get the APRIL history back? APRIL is gone from the list. jumps to March after the last 7 days

I went to RESTORE but this talks about BOOKMARKS It shows for today may 7, 149 items for example then it shows April 29, april 9, april 4 april 1, each with about 150 items but if I were to click on these it says will replace all BOOKMARKS,

thank you

When I would mouse-over a thumbnail on the Youtube home page I use to get a video preview with sound and text controls displayed. Video preview and controls are now missing on homepage thumbnails. Is there a way to get preview and controls back ?

I cleared the cache and cookies...no effect. Problem does not exist with Edge browser.

Using Windows 10 / Firefox browser 125.0.3 (64-bit)

Hi All,

Any idea why the menu code I'm using below to reduce padding in menu items is only affecting Firefox in Windows 10, but not in Windows 7?

Please see attached images.

It's a very strange anomaly. This is true for both FF 125 and FF 115 ESR.

Thanks to all who respond.

/*** Tighten up drop-down/context/popup menu spacing (8 Sep 2021) ***/ /*

 padding-block: 0px !important; /* reduce to 3px, 2px, 1px or 0px as needed */ 
 min-height: unset !important; /* v92.0 - for padding below 4px */

}

I keep getting notifications asking me to update firefox every couple of days. I download the update, it goes smoothly, the notification disappears, but it comes back in a day or two. I also have my setting to supposedly do updates automatically, but that doesn't seem to be working. Please help!

It takes forever for my home page (MSN) to load when I first start Firefox. Can that process be speeded up? I suspect there's a way to get my home page to load faster. Can someone help? Thank you, Firefox.

I am running Windows 10 (64-bit) Version 22H2 OS build 19045.4355 with the Firefox browser v125.0.3 and since updating to the latest Firefox version I am no longer able to load more than 17 Tradingview tabs and the Tradingview tabs I do upload take a long to to refresh or to save changes too. I do not have this issue using other browsers.

I have enabled Firefox Sync between my laptop and my Android. When I go to the manage history tab on my laptop, the history of both my laptop and phone is shown but without the device the tab was viewed on. Is there a way to filter history based on which device I viewed on?

I can no longer play any podcast since upgrade to 125.0.3 The arrow/button to play any podcast is neutral, is not active. Or, on spotify if finding a podcast on gardening, clicking the play button plays something on a completely different topic.

Howdy,

Workflow: I have a firefox instance already running. I want to launch a new firefox in safe-mode to test something without disrupting my existing firefox.

Problem: I try to launch a new firefox in safe mode using `firefox --safe-mode`, but firefox just opens a new window NOT in safe mode.

I think it may because firefox in safe-mode requires launching launching from a new instance rather than attaching to existing instance.

`firefox --help` shows a flag I can use:

--new-instance Open new instance, not a new window in running instance. --safe-mode Disables extensions and themes for this session.

So I run `firefox --safe-mode --new-instance`

now I get error popup with message:

"Firefox is already running, but is not responding. To use Firefox, you must first close the existing Firefox process, restart your device, or use a different profile."

Now I think what is the point of the flag "new-instance" if Firefox doesn't support multiple instances?

Regardless, how can I launch firefox in safe-mode without disrupting my existing firefox instance and without relying on creating a profile just for this?

I'm having trouble using a particular site, that I used to be able to in particular clicking on sub menu's from a context menu if that is the correct term, meaning I cannot click an item/button to reveal a menu below it. From the image supplied there are 2 'menu's' with a < character that when clicked should reveal a sub menu of items, works in Edge/Chrome etc.. the only extension I have is Keeper.

My yahoo homepage on firefox looks totally different than it did last week. Chrome and edge still look like the home page should but firefox does not. I screen shared with yahoo and they said it was a firefox issue. Anyone know how to make the homepage look like chromes and edge? I added pics from edge and firefox for comparison.

I am using Firefox 125 in Windows 11. And this just happens recently.

Sometimes, quite frequently, when I click the addressbar wanting to input or select a new address. The Firefox UI freezes (before the dropdown list of addresses is shown). The video/audio/other effects are still working, and from task manager, it does not cost more CPU/mem than usual. But it does not response to key press or mouse action. All I can do (that I know of) is killing the processes. The problem does not seem related to "current" webpage I am browsing. And I have not installed new addons for a few months.

Any idea what should I look into?
