Hello:

When I signed into my computer this morning, a pop-up asked me if I wanted Firefox to update. I let it do that, and then a pop-up came up letting choose among some photos and art for a desktop background. It even let me upload a photo of mine. I chose one of yours, now I can't change to any other photo I have on my computer. Please help.

Thank you,

Cynthia M.

allow audio and video is preset as the default, however, it is still muted. when you got to mute audio it won't play the video, and no audio/video seems to be working fine, I've followed all the guides, tried everywhere I'm aware of in firefox and nothing seems to work

All of a sudden, the text in my Bookmarks bar has turned black making it unreadable on the black background. Any idea why this happened and how I may revert the text back to white? Thank you for your help.

I have a lot of Firefox windows and tabs open, and I really don't want to lose my session.

I wanted to open a webpage in Firefox in fullscreen mode. But evidently there's some kind of serious flaw in Firefox that makes it incapable of opening webpages in fullscreen mode. Everyone says the only workaround is to open the webpage in kiosk mode. So I tried it.

But now I have two big problems:

1. One of my Firefox windows, with all its tabs, is stuck in kiosk mode. (Even if I close the window and then restore it with Ctrl+Shift+T, it's still in kiosk mode.)

2. All new Firefox windows I open with Ctrl+N are also stuck in kiosk mode.

I don't know what to do, and I'd really appreciate any help. Thanks!

Hi,

Firefox version: 139.0.4 (64-bit) OS: Windows 11

I have been having issues where Firefox tab will just crash out for no reason it appears and it happens at random times and once the tab start to crash, and I restore it, it will crash again and again. The only way tog et out of the loop is to restart Firefox.

I have tried: Refreshing/Reset, Clearing Cache and History removing all themes, disabling extensions, disabling my anti virus. Turning off hardware acceleration didn't make any different.

I currently have 2 extensions enabled: uBlock Origin 1.64.0 and Bitwarden Password Manager 2025.5.0

In the about:Crashes I have reported them all and they seem to have the same type of reasons in the Raw data/Minidump which are: EXCEPTION_ACCESS_VIOLATION_WRITE EXCEPTION_ACCESS_VIOLATION_READ

Any help as to what to try next?

Firefox has just introduced wallpapers for browser home page. I cannot get it to work. It's either cropped too small or pixilated, is there a setting I need to adjust, or a particular image format? So that it looks ok.

My desktop has a line where you search. I do not have the full line. Missing view history saved bookmarks, home,print, settings screen shot. I have a new laptop two days old. The top of the home page look different from what appears on my older desktop. How do I get the full line. Also the very top of the screen says file, edit, view,History, bookmarks, tool and help. I do i get these features?

Is there a way to protect selected cookies from being cleared when you need to clear cookies to access a web site? I don't like to lose the sign in cookies from sites I visit often.

Recently my HBO max started to not load on firefox... I've tried the usual suspects, cleared cache and cookies multiple times, but when trying to pick a profile, just a black screen loads. Nothing happens.

Picture below, every logged link of the site is like this, i can only access links before login, like answers/support/ads,campaigns etc. Those kind of pages load.

Also, sometimes, when accessing the site through search engines, the site loads, but on a different profile than the one I use, but when trying to switch profiles, the same thing happens again, nothing loads.

Today (06/12/2025) upon opening a new tab, Firefox slid the new option of uploading a custom picture to apply to the background. Tried the new feature, now I can not find the setting that allows me to change the picture. I read the thread "Customize your wallpapers". The instructions are as follows; You can personalize your Firefox New Tab page by adding one of the available wallpapers. Follow these steps:

  1. In the right corner of the New Tab page, click the gear IG settings icon.
  2. In the customization panel, under the Wallpapers section, you will see different categories like Solid colors, Abstract and Photographs.

       Click the category you prefer. For example, selecting Abstract will show a variety of abstract designs. 

The problem I have is the customization panel is no where to be seen, I have click on EVERYTHING possible, it is not in my settings, why? How do find this?

I cannot display Amazon Deals properly that contain multiple he products. The home page and single products display normally. should be. A page with multiple products has large blank areas where the product should be. If I move the mouse over these spots, a soundless video will often display.

My clearing of the temporary cache files did not help. Stopping Ghostery doesn't help either. Other add-ons include Last Pass, Honey, Review Meta and Facebook Fences.

Help is appreciated.

Firefox on new laptop windows 11. (AMD Ryzen 7 5800HS with Radeon Graphics)

Firefox on new laptop windows 11. (AMD Ryzen 7 5800HS with Radeon Graphics)

Have noticed only when i use Firefox i get intermittent flickering on the screen. It does not effect browsing, though it has frozen on a couple of occasions. I don't know if that is connected or just something else.

I have tried two trouble shoot 'fixes' i found whilst looking for a solution and neither have worked.

1 - turning off recommended performance settings and hardware acceleration. 1b - turning hardware acceleration back on.

2 - checking in troubleshoot mode to see if it's an extension. Flickering happened in troubleshoot mode too.

Microsoft seems to have cut Firefox out for video chats. This is a recent change. Their message is that video is not supported by my browser (Firefox)

I love having the ability to group some of my tabs but I'm wondering if it's possible to create "subgroups" of tabs inside of a "group". For instance, it would be very confusing & even chaotic to have one tab group named "Computers" that has tabs for sites where I buy computers/parts/software, sites where I go to for support for my hardware/software issues, & sites where where I can read reviews about the up & coming new hardware/software. However, the chaos would go away if I could have 3 tab subgroups (Shopping, Support, & News) UNDER a "top level" tab named "Computers".

From what I've been able to find on the Firefox website, this capability is not yet available but I'm wondering if it's something that's currently in development. If not, I would like to suggest that it be seriously considered. I realize that some people could take this kind of capability to the extreme, with hundreds of tabs organized using multiple "sub-tiers" & trying to develop something to support the extreme cases would be a nightmare. However, the ability to even two levels (groups & 1 level of subgroups) would be a HUGE improvement over the current situation.

This just started happening a few days ago, once I click into an email in the unified inbox it disappears from the inbox. Prior to that the email would remain in the unified inbox showing as read. Now the email will still be in the individual email address inbox, just not in the unified inbox. How do I change this back? I'm running three email addresses through thunderbird.

I updated firefox, and all my addons and sign ins are gone now. Search history and tabs remained intact. It also created a folder on my desktop, but I'm not sure how do I "extract" my old data from it.

PLEASE HELP! I allowed Avast to do a "clean up" this week. That usually entailed a "scan" for viruses. NOT ANYMORE! My computer is really messed up! I just tried to delete Avast, and even though I hate to see ads, I think their Ad Blocker is messing up my PC. I just noticed that when I asked what I thought was FIREFOX a question, the answers were supplied by an entity called THLIOKNI. WTF is THAT?????? Seriously, what is happening to my relatively NEW PC--had to buy a new CPU in October of 2023. And I've always used Firefox. But WINDOWS 11 is the operating system on this PC, and it is NOT compatible with Firefox apparently! I'm an elderly woman and I cannot handle this stress! What I also noticed is that I read Substack writers and depend on them for accurate description of current political and social news, but now I can't access the "like" buttons on commentators. Is that a Substack issue (I don't think so!), or is it something to do with the Avast "clean up?" WHAT ON EARTH IS THLIOKNI and how the hell did that get on my computer? PLEASE ADVISE ASAP! And I sincerely hope a REAL PERSON reads this! I do not want a million responses from other readers at other times, I want to hear from a REAL PERSON! You have my e-mail address. Catherine O'Kelly
