What happened to the home page? It now has a different format after a recent update. There is too much white space and the placement of the desired icons has shifted down on the page.

Anyone have any experience with this annoying issue?

Thanks.

Sites are now crashing because Firefox has "run out of disk space"

My most full drive is only 72% full and there are multiple other drives I could switch to with terabytes of spare storage. I also have plenty of indexes free, these are only 2% used.

But how? The solution page only offers advice for clearing cookies and data. I don't want to do that.

I have tried increasing dom.storage.default_cache and dom.storage.(I can't remember the exact syntax, but it was the site specific default cache), and I then tried killing and restarting chrome, but the issue persists and it means I can't run WhatsApp in my browser anymore, currently the only Linux WhatsApp solution.

It also affects multiple sites which struggle to load the css correctly, or crash altogether (the firefox help page and deepl.com)

Hi,

I've got Firefox with 4 adblockers: AdBlocker Ultimate, AdLock, Element Blocker and uBlock Origin. Still, https://www.youtube.com/c/franceinfo/live (news channel) sneaks ads before and after the weather forecasts. "C'était la météo avec Florette" (you watched the weather forecast with Florette salad sauce - of course I didn't!).

I can't find how to get rid of it. Please advise.

I wanted to get a refund for the VPN I purchased but the instructions provided on your FAQ [ https://support.mozilla.org/en-US/kb/how-do-i-request-refund-mozilla-vpn ] do not work. I have been unable to make a request.

The GPU isn't working properly... I've attached screenshots of the browser I have installed. If needed, I can take any logs, etc. It's very frustrating - I have a fairly old processor and its GPU isn't working properly! If needed, I can create a thread on the forum and attach any information about my system. Sorry if I'm in the wrong place! Best regards, and thank you for the best browser in the world!

So, I've just went on a quest to find a solution to my pinned tabs disappearing every few days, and it seems like this can happen if I don't shut down Firefox properly. Is there a way to stop this from happening?

That's my question. The rest of this is curiosity about the issue since it's seemed to have persist for a few years:

Is this intended behavior? No other browser I use does this and judging from the hits I got here, and elsewhere, it seems undesired. Is there some security or privacy reason it's like this?

I know I can repin the tab, or take some session recovery steps, and a few other things... but IMO, those are workarounds, not solutions. Barring some technical or mission limitation, a true solution should prevent this from happening at all.

Hi all the people,

I was just surprised to see this in an Apache HTTP log: "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Firefox/58.0.1"

This bugs me. My first guess would be that a Webkit based Firefox could not be qualified as really Firefox. Although that, I could imagine a Firefox for iOS or MacOS based on Webkit, may be, but it says it is on Windows, which makes less sense.

I suspect this is a user agent string spoofing, but I just need to be sure (I try to get ride of far too invasive bots, while I’m afraid to disrupt browsing from legitimate web users).

With thanks and my apologizes for such a question which may looks obvious or strange to people who know for sure.

Resolved Update: apparently cat cannot write to /etc. Resolved by using:

sudo tee /etc/apt/sources.list.d/mozilla.sources <<eof types: deb uris: https: packages.mozilla.org apt suites: mozilla components: main signed-by: etc keyrings packages.mozilla.org.asc eof p></eof>

The instructions need updating!

_________________original problem (in case some one else needs the information)

I am following the instructions in section "Install Firefox from Mozilla Repository (Recommended)" at https://support.mozilla.org/en-US/kb/run-firefox-chromeos At step 4 I am receiving a permission denied error: "-bash: /etc/apt/sources.list.d/mozilla.sources: Permission denied" I am not sure how to resolve or continue.

Last command and output:

Hi there.

So as the title suggests, I have an odd issue, where audio from calls gradually pan around my headphones. It starts normally, but slowly goes towards the right ear, and eventually it starts moving back towards the center, but very muffled, as if something is simulating audio going behind my head, then left ear, then back center. This happens across different computers, OS's, audio interfaces, headphones, so the issue is highly likely to stem from within Firefox, although I'm not ruling anything out.

I've had this issue for probably years at this point, but I very rarely take calls (ie. Teams, Messenger, Discord), so it's never been the biggest issue, but now I have to regular do calls on Teams, and it's driving me slightly nuts. This does not happen while running the respective apps, but frankly, I'd rather not have to do that.

It seems to be related to WebRTC, but I can't find a specific setting that changes anything in that regard.

Randomly my firefix just get loggedout and when i immediately logged it in again using mozilla i cant see my bookmarks my other accounts my profiles and all my groups and other information it was like i had made a fresh account all my data is lost what to do ? PLZ help i really want my data back i have been trying to get my data. Working on it for last hour.

When I open the history menu and search for any term, even a term that should return a bunch of results such as; http, google, search, results, <any keyword that I just searched> no results are EVER found. My history menu shows over a year of browsing data, but when I go to search it the search always returns NOTHING. It doesn't matter what I search in the history menu search bar, I always get no results. Yes, my history is being recorded, whenever I visit a site it is immediately visible in the history menu.

Stuff I already tried: Restarting firefox (duh!) Rebooting my computer Uninstalling my extensions Trying it in Privacy Mode Help>More Troublshooting information>Places Database>Verifty Integrity showed that my DB was "sane"

However, when I create a new profile and browse a few sites and search then the history search bar does work (in that profile). Based on that I think the issue is profile specific, but I didn't change any settings in my profile that I can think of. Any ideas what could be going on?

I logged into my account to try out the VPN. I get to the screen shown in the attached image. It wants me to "go to the open panel and turn it on." What is the open panel it refers to?

I submitted a bug last to Bugzilla last Sep. that seems not yet to be assigned to anyone, and a bug two days ago that wasn't acknowledged. Is the Bugzilla site working? Should I be doing something else to report the bug?

Firefox dropdowns, menus and popup menus do not appear after resume from suspend on Ubuntu 22 or 24 This has been happening for only the last few weeks. Even dropdowns on web pages do not appear. I can click the dropdown and cursor down then hit ENTER to change a dropdown's value but I cannot see anything while I'm doing it. On the menus, I can use hotkeys if I remember them but the menus themselves do not appear. Right-clicking to get a context menu also does nothing but it behaves like it did. If I right click something, nothing changes on screen but if I then click another link or button, the first click is swallowed to dismiss the non-existent popup.

Other apps on the system work fine including Chromium browser.

This only occurs if I start Firefox then suspend the machine and then resume from suspend. After resume, the menus, dropdowns and popups no longer appear.

I am running Ubuntu 24.04.4 LTS on a Dell Optiplex 3050, Core i3-7100x4 , 16 GB ram, Intel HD graphics 630 (KBL GT2), Gnome 46, Wayland windowing system.

I tried Firefox safe mode, clearing the caches, etc. Nothing worked.

Firefox for Linux Mint mint-001-01 150.0.3 64 bit Issues with login on ups.com When I press on the Login radio button I get this:

Works in all other browsers on same system, Chromium, Brave, Opera, etc Works on Windows 150.0.3 64 bit Cleared cache,cookies, disabled all extensions, disabled advanced tracking protection, every suggestion I could scrape the internet for. Ran Firefox logger and it found a 403 error. Any suggestions? about to nuke and reinstall

• • Background:**

I'm a senior software engineer running Firefox Developer Edition on a Linux machine with 8GB RAM. I have Fission architecture (site isolation) enabled, which I understand is now the default since Firefox 95+.

• • The problem:**

When I open 20 or more tabs across different domains, Firefox's memory consumption scales dramatically — often reaching 4–6GB of RAM for what should be lightweight browsing sessions. This is significantly higher than what I observed before Fission was enabled.

• • What I've already tried:**

- Disabled hardware acceleration → no significant improvement - Set browser.tabs.unloadOnLowMemory to true → partial relief

 but tabs reload constantly, disrupting workflow

- Reduced content.notify.interval → marginal improvement - Tested with all extensions disabled (safe mode) → RAM usage

 still high, confirming it's not extension-related

- Checked about:memory → large number of separate

 "Web Content" processes, one per origin as expected with Fission

• • What I'm trying to understand:**

1. Is there a way to set a maximum process count cap for Fission

  without fully disabling site isolation? I found 
  dom.ipc.processCount but changing it doesn't seem to affect 
  Fission's per-origin process spawning behavior.

2. Is browser.tabs.min-warm-process-count a relevant setting here

  and what is the safe range to modify it?

3. Does Firefox have a built-in memory pressure threshold where

  it automatically consolidates processes — similar to Chrome's 
  memory saver — and if so, which about:config keys control it?

• • Environment:**

- Firefox Developer Edition 151.0b10 - OS: Ubuntu 24.04 LTS - RAM: 8GB - Fission enabled: confirmed via about:support - Extensions: disabled for testing
