I-Firefox Community Forum

Since yesterday, some of my tab groups don't fully collapse when the group tab is clicked. Instead, one tab in the group remains fully expanded, followed by a number indicating how many other tabs are in the group. A screen shot is attached.

Since I enabled tab groups some weeks ago, tab groups have behaved as expected. When the group header is clicked, the tabs in the group spread out to be visible and clickable. When the header is clicked again, all tabs in the group collapse entirely behind the header tab.

Most of my tab groups are still behaving this way. But new groups are now displaying one full tab plus the number, no matter how many other tabs or tab groups are already occupying the window.

Since the behavior is inconsistent, it doesn't seem to be a setting. Is there any fix?

I have these printers.

"HP LaserJet M109-M112" (the Windows default) "HP LaserJet 1020"

Regardless of the value of print.sav_print_settings, the first print dialog after starting Firefox shows "HP LaserJet 1020".

If I manually put "HP LaserJet M109-M112" (no quotes) in print_printer, it reverts to "HP LaserJet 1020" the next time Firefox starts.

How do I make "HP LaserJet M109-M112" Firefox's default? Thanks.

Здравствуйте! Я попробую описать проблему на английском и на русском, надеюсь получить ответ и решение как исправить то что я хочу.

В версии браузера Mozilla Firefox 68.0 или Firefox 68.12.0esr прозрачность как в предпросмотре при наведении курсора на вкладку, однако в Mozilla Firefox версии 142.0 или 142.0.1 открыв вкладку, вы увидите замыленность или мутное изображение.

Как видите, на предпросмотре лицо девушки нормальное, прозрачность хорошая, но когда я открываю вкладку, лицо девушки становится мутным. Как сделать прозрачным? как убрать эту мутность?

Hello! I will try to describe the problem in English and in Russian, I hope to get an answer and a solution on how to fix what I want. In Mozilla Firefox 68.0 or Firefox 68.12.0esr browser version, transparency is as in the preview when you hover over the tab, however, in Mozilla Firefox 142.0 or 142.0.1 when you open the tab, you will see a blurred or cloudy image.

As you can see, the girl's face is normal in the preview, the transparency is good, but when I open the tab, the girl's face becomes cloudy. How to make it transparent? how to remove this turbidity in Mozilla Firefox 142.0 or 142.0.1?

I posted 2 files. Blurry is Mozilla Firefox 142.0 or 142.0.1 Where it's transparent, it's old version Mozilla Firefox 68.0

Hello,

I really like using the "Shortcuts" (Top Sites) feature on the Firefox new tab page. However, there is one problem: Firefox automatically adds new shortcuts from recently visited sites.

I would like to keep only the shortcuts I manually pinned, without Firefox suggesting or adding new ones automatically. Currently, if I disable browser.newtabpage.activity-stream.feeds.topsites, all shortcuts disappear, and if I leave it enabled, Firefox keeps adding unwanted sites.

Could you please add an option to disable automatic shortcut suggestions while keeping only pinned shortcuts? This would make the feature much more convenient for users who prefer to manage their shortcuts manually.

Thank you!

Hello.

My Firefox browser is missing the close button from the top bar. Minimize and Maximize buttons are present.

This is happening on Fedora 42 With Gnome.

I believe I don´t have any custom theme or user css or extension that could cause this.

Also because, it seems to be hapenning not only in Firefox itself, but also in Firefox based browsers, like Tor Browser.

Anyone has any idea what is hapenning?

Thank you.

I recently installed Win 11 on a new Acer Aspire (with MSI MAG244F monitor) but the issue seems to be present on my Acer Nitro 5 with built-in monitor as well.

I don't think it's an Acer issue but I am only running Win 11 on the two Acer machines. If I open a web page with colored graphics or pictures and then drop down a menu of the browser (bookmarks, etc.) the colors of the graphics bleed through. It's annoying and somewhat obstructive. It does not occur if a window from a different app is opened on top of the browser window no matter how bright the colors are.

I attached a few edited screenshots to show the issue. The edits are only to cover personal information etc.

The issue seems to be color saturation and does not occur on my other Win 10 machines or in other browsers. Not even the same version Firefox on the Win 10 machines.

Is there a way to increase the opacity of the drop downs or lower the color saturation in the Firefox browser?

I noticed that Firefox updated today or recently. I am having a lot of trouble with the browser today. Many complex pages aren't loading and just have overlapping photo icons. I can't use certain pages where I enter and save data. When I try these pages on chrome they open without problem. Is this some firewall that is over the top or is it something happening only today? Because if Firefox is like this now, I'll have to stop using it.

Whenever I play something in the browser while connected to my TV by HDMI, the sound still comes out of the laptop speakers. This happened suddenly, without any discernible reason, and I can't seem to fix it. Everything else works, only content played from Firefox remains in the laptop speakers. I've checked my audio mixer, nothing seems amiss, I've updated Firefox and refreshed the application, still nothing. Hell, I've even tried different cables and HDMI ports, but nothing works. What could be the issue? Why did my audio suddenly stop working, and what can I do about it?

There are times that when I open firefox that some of my tabs that does this weird thing where my tabs from the previous session that I left doesn't load up, from what I see is a blank tab that doesn't access the sites I left. It's been twice since I encountered this and I can't replicate the issue. When it happens I try checking out the recently closed tabs or window it doesn't show the ones that didn't show up.

I installed chatgpt, but I've found it more of a nuisance than a help. I've tried on-line to find out how to remove it but none of the suggestions seemed to work. I'm using the latest version of firefox on a Macbook Pro. Any ideas welcome. Charlie

Using Firefox--When I try to access the daily set of images that comes in an email representing memories for this day which is pulled from my Onedrive Photos, all I get is a dark blank screen with a subtle pulsing wave as if it is searching.

I get the same thing when I go directly to my OneDrive Photos and try to pull up the daily photos there.

However, changing browsers and using Google Chrome--I can view the images in the memory email as well as those on my OneDrive directly

What does Chrome do that Firefox is not?

I recently had another browser related issue on a different problem trying to register online with Directv which would not complete with Firefox but when I used Google Chrome instead of Firefox, it worked.

This made me wonder if the above OneDrive image problem might be browser issue. Sure enough, it was.

I really prefer Firefox and I do not want to have to go to Chrome.

Windows 11. I have my taskbar behaviour set to ‘Automatically hide the Taskbar’ So usually the Taskbar is not displayed, but when I move my cursor to the bottom of the screen it reappears. With Firefox I cannot make the Taskbar reappear.

For a while now firefox has been unable to enter fullscreen when pressing F11. Instead all it does is move the "Scroll forwards", "Open a new tab", and "List all tabs" button over slightly (The buttons on the top right, next to the minimize and close buttons).

I don't know what's going on with firefox.

Firefox Version 142.0.1 (64-bit)

Using Firevox 142.0.1 on a MacBook Air. I always have "Always ask you where to save files" checked in Preferences, but lately it sometimes fails to ask me. For example, if I try to download a file from Google Drive. Is anyone else having this problem? Is there something I can do about it?

Ubuntu - I use the SNAP version of Firefox - I generally have lots of tabs open but only use 5 or so of them and it's generally fine.... but when I am closing Firefox, it USES like 100% of the CPU and ALL of the RAM and ALL of the SWAP memory when closing.

This locks up the computer.

Sometimes it doesn't quite go all the way but I can watch it all happen in real time, using Task Manager - and that shows a solidwall of all resources occouring, when the close Firefox is run.

I am told by research via ChatGPT that this is a very real problem with the SNAP version and it's best to change to the Debian version, copy all the bookmarks etc., across and then uninstall the SNAP version.

It's rather disconcerting to have Linux crash because of this one app locking it up and frequently.

Chat GPT:

Is there a problem with Firefox Snap Version closing and using all the resources while doing so, which results in locking up the computer?

You're definitely not imagining it—there have been reports of Firefox's Snap version consuming excessive system resources (CPU, memory) and even causing lockups or hangs, particularly during closure. Here's what’s going on and how to mitigate it:

What’s Happening with Firefox Snap?

2. Browser Hangs or Locks the System on Close

On Linux (especially Ubuntu), users have reported that closing Firefox can lead to it hanging in memory, sometimes unresponsive and still consuming resources.
Super User
Ask Ubuntu
A stark example from Reddit illustrates the severity:
“About 50% of the time I open Firefox, it'll reach 100% CPU usage in about 30 seconds… PC completely unusable unless I shutdown.”
Reddit

3. Known Wayland Sway Bug

On Wayland/Sway setups, reloading Sway while Firefox is open can trigger intense logging, causing high CPU use and an enormous syslog.
Fix: Set MOZ_DISABLE_WAYLAND_PROXY=1, or upgrade to FF 125 where the issue is addressed.

Alternative Approach

Many users, particularly on Ubuntu, opt out of Snap completely in favor of the .deb package or PPA builds. These alternatives often avoid these specific issues. Ask Ubuntu Reddit

Thanks in advance.

Firefox: 142.0.1 (64-bit) macOS: Sequoia 15.6.1 (24G90)

A repeat of a problem I was having a couple of months ago. I go to the reddit website and login with no problems but when I try to comment or load specific threads I get the attached warning come up:

"! Your request has been blocked by network security. Please try to login with your Redit account."

Which doesn't make sense as I'm already logged in. Last time it seemed to clear after 24 hours or so although not because of anything I did as far as I'm aware.

1. Started Firefox in Troubleshoot Mode - problem remains … 2. Cleared Firefox Cache/Cookies and restarted Firefox - problem remains … 3. Shutdown and restarted iMac - problem remains … 4. Problem not happening with Safari or DuckDuckGo browsers … 5. Checked macOS Local Network security. Firefox has access but turned off access and turned back on, restarted iMac - problem remains …
