I use eBird extensively. When I try to play the audio (with sonograms), I get a message that says "We are still processing this file. Try again later". These files perform well on my Android phone, so I know it it is not eBird's glitch. I am confused about the setting options on Firefox that I need to set. These files are usually .wav format. I have tried to open a ticket with eBird, but have not had a response. Can you guide me? Thanks.

I'm suddenly getting repeated/multiple Mozilla Firefox "Browser Alerts", "System Warnings," and "McAfee Critical Virus Alerts" that are wrong and dysfunctional. They pop up every few seconds. They contain "Remove virus now" and "quick scan" buttons, but these only take me to a bright red screen that says:

"Deceptive site ahead Firefox blocked this page because it may trick you into doing something dangerous like installing software or revealing personal information like passwords or credit cards."

These come even though I haven't tried to access any "deceptive sites." I have to x all of them out to clear my screen.

There's obviously a defect in your warning system. How do I stop this?

Even when I open a new tab in Firefox, the focus remains on the address bar. I'd like to know how to fix this. When I open a new tab, the address bar gets the focus, which I find inconvenient. Is there a way or setting to prevent the address bar from getting the focus and instead focus on the search box in the middle? I've searched online and tried the "settings in about:config" suggested in the search results, but it didn't solve the problem. Is it impossible? Firefox 153.0.3 64it

Hello! I'm on Debian, and there Firefox ESR is the default browser, it is now basically unusable as it is so out of date that Cloudflare Turnstile no longer works.

This is a major problem.

I have opened a ticket over at Cloudflare, but they have not commented at all on the problems: https://community.cloudflare.com/t/turnstile-not-woring-for-the-last-few-days/939637

Thank you for your time.

I use WhatsApp web with Firefox 151.0.3 on a Macbook Air. In WhatsApp web, you should be able to emoji over a message sent by someone else. One clicks on the smile icon at the side of the message, the emoji pallet appear above and select one of a handful of emojis. Since a recent update, the pallet no longer opens. It's just white space, the cursor does not change allowing you to pick one of the emojis. See screenshot. Is there a fix for this please?

Yesterday, Facebook started to take longer and longer to load a page. Whenever I tried to post something and it took forevahhhh for it to show up on the timeline. I had to reload and repost several times since yesterday. All other websites are loading up just fine, but Facebook has taken as long as 30 seconds, sometimes even more before it refreshes a page.

Then.. it got worse. All I could see was the Facebook logo in the middle of the screen and nothing else.

Then it got even worse. As of this morning, I can't even get any results when I google Facebook! I put Facebook into the search bar, click return -- and nothing happens, absolutely nothing.

I'm not seeing any problems with any other website. I have already restarted my modem. I have already cleared out the cache and the cookies. I have restarted my laptop three times. I even looked up Downdetector, but there aren't any problems with the website in general.

Those are all the solutions I've found when searching about this, but the problem is only becoming worse, with everything I try. If there's something I need to change in Facebook settings, I can't do that, because now Facebook is completely inaccessible.

This is only happening on my laptop. Mobile is fine.

I have just reopened my Firefox and have found that recent changes have suddenly put my tabs right at the top of the window - initially very confusing because I feared that I had lost them. I would like to put them back where I find them easier to work with, how can I do that?

On my Ubuntu computer, I find that the New Tab extension does not update like in my Windows computer.

Does the extension update at the same time as on Windows? Is there a way to make Firefox update the extension since going to Extensions does not appear to do that for this extension like those I have installed myself?

Anyone succeed with running Firefox in headless mode under Ubuntu?

I tried:

firefox --headless --safe-mode -P headless https://quan.hoabinh.vn

but got this error:

[12545] Sandbox: CanCreateUserNamespace() unshare(CLONE_NEWPID): EPERM

• • • You are running in headless mode.

[GFX1-]: RenderCompositorSWGL failed mapping default framebuffer, no dt

I installed Firefox as from "https://packages.mozilla.org/apt" repo.

Under Settings>Privacy/Security>Browsing Data there is no longer the option to Manage Cookies, despite the help section saying that is where to find it. There is no other place in all of Settings to find the list of cookies. There is only the ability to delete all cookies in History, which I have no desire to do. I edit the cookie list weekly, and it is only now, mid August 2026, under Firefox 153 on Win 10 that I no longer have access to them. How do I get it back?

I have all the location settings I can find on my Firefox browser, google, and device turned off, but the new firefox weather widget still had my hometown as the default location, which is is not the same location as my IP address. And when I went to buy a book online through Thriftbooks with a guest account the address line autofilled with addresses in my hometown. I do not have any addresses saved to autofill. Where is this information being stored and how do I get rid of it?? Is there something in about:config I can shut off or disable?

Thank you for your time and assistance.

My current version of Firefox is 149.0 (64 bit) Mozilla Firefox for Arch Linux Arch Linux - 1.0 I am running this on two computers, a laptop and a desktop, both running Arch Linux, currently at 6.19.10. I use the laptop much more, and recently noticed that I cannot upload or download files with Firefox. No file selection window opens and the request is simply ignored. Nothing appears in my Downloads folder. Meanwhile, I also noticed that this function works just fine on the desktop computer. I don't remember making any settings changes. I do have popups generally disabled but can enable them for certain sites. In any case, I have tried enabling popups and redirects completely with no change. I figure there must be something different about the settings on these two Firefox installations, but what? What can you tell me? Or ask me? Thanks.

I've searched & waited past few years for an Extension to make the TOOLBAR FONTS larger, none found. Reason being many of us are using larger monitors and TV's and we're usually sitting or standing further away from the screen. Problem is the font size cannot be changed, they stay small and hard to read comfortably. __YES I've reset my operating systems font size, that does not work in Firefox TOOLBARS. __Changing the "firefox/addon/theme-font-size-changer" has been eliminated by Firefox. __Changing the "layout.css.devPixelsPerPx" to a larger number increases the whole TOOLBAR. I just want the FONT size larger. __(someone suggested) NO, I'm not going to setup 2 monitors.

Sure would like this issue fixed. In the pix below, it has been done.

I'm getting the following error message:

The bookmarks and history system will not be functional because one of Firefox's files is in use by another application. Some security software can cause this problem.

I don't know what prompted this concern on my Windows 11-based laptop, but I only noticed this last night doing some research for another issue. I don't have any of my bookmarks showing up in the bookmarks section, nor will it allow me to click the star on any tab to bookmark the page. I have restarted and shut down my laptop several times and this is not solving the concern. Let me know if you need more information or if I need to start this inquiry again elsewhere, but again it sounds like the same concern.

I have included a screenshot of the exact error for accuracy's sake. Like everyone else here, I'm trying to get my bookmark and history access back up and running but not sure how to go about it.

I couldn't get past the first fix suggestion because I am not sure how to restart Firefox (https://support.mozilla.org/en-US/kb/fix-bookmarks-and-history-will-not-be-functional?as=u&utm_source=inproduct&redirectslug=The+bookmarks+and+history+system+will+not+be+functional&redirectlocale=en-US). I have restarted my laptop several times but the issue still persists.

Please advise.

Ironically, I am not having this issue on my older PC that is still operating on Windows 10. I can view history and access or add bookmarks with no concern to my knowledge.

Every time I try to log onto https://find-and-update.company-information.service.gov.uk/company I get the following message Secure Connection Failed An error occurred during a connection to find-and-update.company-information.service.gov.uk.

Certain websites can be reached and displayed, however when using their page search, it says access denied on this server. I've tried using another browser but the same message comes up. However, on my phone, and tablets, I have no problem.

I get messages, questions and info from Firefox in Dutch. My language preferences in setting is English UK across the board. Browser, preferred, fall back and web site language. It works most of the time, apart from with Firefox. What can I do to make Firefox talk English to me?
