I am using Firefox v140.0.1 Snap on Kubuntu 25.04, Kernel 6.14. Since the Firefox update in the past couple days, the mouse cursor has started appearing huge and slightly blurry (as though the image is scaled up) in Firefox and nowhere else. The size is visually annoying, and occasionally difficult to know exactly where I'm clicking (trying to move the caret in a text box for example). It also appears to be a different style from the main desktop cursor, the shape and color are ever so slightly different, but this may already have been the case and I simply didn't notice because of the previously small size. Firefox doesn't have its own built in cursor settings that I can find, nor obey the system cursor settings. I have a high DPI display so perhaps it is being over-compensated for? e.g. both the system and Firefox are scaling the cursor up, assuming the other hasn't done it already, resulting in a cursor that's too big.

My OS is Linux version 140 -- I don't have the privacy /tracking prevention option your settings advises to use. Please advise why and how I can accomplish this block. Thank you.

Your support page -

Introduced in Firefox version 120, you can make use of Global Privacy Control (GPC) to automatically notify websites not to sell or share information about your browsing session on that website.

GPC operates as a “Do Not Sell” mechanism in some US states such as California, Colorado and Connecticut. It may also be used to indicate an opt-out of targeted advertising or general request to limit the sale or sharing of your personal data in those jurisdictions, as well as in jurisdictions such as the EU, UK, Nevada, Utah and Virginia.

To turn on this preference:

   Click the menu button Fx89menuButton and select Settings.

Did Not Connect: Potential Security Issue

Firefox detected a potential security threat and did not continue to nrega.nic.in because this website requires a secure connection.

What can you do about it?

nrega.nic.in has a security policy called HTTP Strict Transport Security (HSTS), which means that Firefox can only connect to it securely. You can’t add an exception to visit this site.

Probably nothing, since it’s likely there’s a problem with the site itself.

There are times that I use the screenshot tool on X.com and the filename it saves to is WAY too long. Sometimes it tries to use the entire content of the post as the filename. I see this effect in the title bar as well. Is there a way to change it so it only uses a date/timestamp and nothing else? Attached is an example of this extremely long naming.

Hi guys,

I connected my private crypto wallet to a fraudulent OKX scammer wallet extension, downloaded from your Firefox store couple of weeks ago. I deleted the wallet after I realized it's a scam but the scammers already drained my entire wallet afterwards, I lost approx. 14,000 USD.

I saw this warning too late: https://t.co/wSQv696SvM

Do you guys have any idea, where I can report this case or what I can do? I mean, I am quite sure that I am not the only one affected by this scam.

Thanks Marc

1. 1. 1. 🔷 **Issue Summary:**

While using Firefox under normal conditions, the system **freezes completely** at random times. The desktop environment becomes unresponsive, requiring a hard reboot to recover. The issue typically occurs during heavier browsing sessions (e.g., video playback or graphics-heavy websites).

System logs (`dmesg` and `journalctl`) show **AMDGPU virtual memory protection faults**, indicating a GPU-related issue triggered during Firefox usage.

1. 1. 1. 🔷 **Log Snippet:**

```text amdgpu 0000:03:00.0: amdgpu: VM_L2_PROTECTION_FAULT_STATUS:0x00641051 Faulty UTCL2 client ID: TCP (0x8) PERMISSION_FAULTS: 0x5 [gfxhub0] retry page fault (src_id:0 ring:0 vmid:6 pasid:32776, for process RDD Process pid XXXX thread firefox-bi:cs0 pid XXXX) ring gfx_low timeout, but soft recovered ```

---

1. 1. 1. 🔷 **System Information:**

• **OS:** Linux Mint 22.1 x86\_64 (based on Ubuntu)
• **Kernel:** (e.g., `5.15.0-xxx-generic`) ← *replace with actual kernel version*
• **CPU:** AMD Ryzen 7 5700U with Radeon Graphics
• **GPU:** AMD ATI 03:00.0 Lucienne (integrated)
• **Firefox Version:** (e.g., 126.0) ← *replace with actual version*

---

1. 1. 1. 🔷 **Steps to Reproduce:**

1. Open Firefox and browse modern websites (YouTube, media-rich content). 2. Use the browser for several minutes (random trigger). 3. Suddenly, the system UI becomes frozen and unusable. 4. Logs show AMDGPU VM fault and `gfx ring timeout`.

---

1. 1. 1. 🔷 **Expected Behavior:**

System should remain stable during normal browser usage, especially with an officially supported AMD APU.

---

1. 1. 1. 🔷 **Actual Behavior:**

GPU driver crashes causing total system freeze, likely triggered by hardware acceleration and memory permission faults inside the amdgpu driver stack.

Has support for X11 been removed?

Firefox screws up showing .pdfs. The first view is fine but scrolling seems to overprint the first view without erasing it, if that makes sense, sorta like a double exposure. I can't get a screen cap either, which might just mean it's not a firefox issue at all, but I can view and screen cap .pdfs from any other application. I'm running Debian 12 up to date. When I need to view a .pdf I use Chromium, but I do prefer Firefox.

In the last few days, after some minutes of usage, parts of Firefox become unclickable:

- I can still click on tabs to change tabs. - When hovering over the cross button to close a tab, it changes appearance as it should. Clicking the button does nothing. Ctrl+w still closes the button. - Clicking on the address bar does nothing. - Cannot click on back, forward, refresh buttons. - Cannot click on any add-ons. - Cannot click on preferences. - Can click on the button to open a new tab. There, I can enter an address. Once the page has loaded, address bar becomes unclickable again. - Bookmarks toolbar is still working as expected. - Keyboard shortcuts (ctrl+t, ctrl-w, ctrl-l) still work as expected.

I'm running ``` Mozilla Firefox 138.0 20250428130755 20250428130755 ```

I have an Arch Linux installation with Plasma desktop. Software is always kept up-to-date. Sometime recently, Mozilla apps, Firefox nor Thunderbird, will no longer print, neither to pdf nor to network printer. These always worked before. Now, if even "print preview" is invoked, the dialog opens as a blank sub window with only the word "Print" in upper right, and at left center is "Preparing Preview with rotating time delay wheel, which never resolves. All other apps, including other browsers and mail handlers, will print without issue. I've tried the obvious checks with no success. Where could be the problem? Is there a helper app shared by Firefox and Thunderbird that could be the issue? The only potential remedy I have not yet tried is complete removal of both Firefox and Thunderbird, as that would cause re-configuration issues for both. It's necessary to press <ESC> to terminate the print window when it fails to respond. Screenshot attached...

To preface this, I am not sure if this is caused by my OS (Ubuntu 24.04) or by the way Firefox tends to work on Linux as other issues have been (and therefore, might be resolved with a change in about:config).

Problem: When I download a file and download another one right after that one, the window showing the folder I am choosing to download to won't show the file/image preview of the file I just downloaded before; it only shows the correct preview once I have opened the file manager on my OS; after doing that the file preview is up to date again. (basically, it only shows the correct file preview when I viewed the files on my desktop before opening the download window and will not keep up to date with the most recent changes on its own like it does on Windows for example)

I'm attempting to sync my account between a Windows host and a Linux host. Logging into my account on Linux brings up a "Authorize this sign-in" window that demands entry of a 7-char "Authorization Code" (not the same as a six-digit authentication code) which is emailed to me. After entering the authorization code, a window appears stating "Bad request - Something went wrong. Please close this tab and try again." This happens consistently, and only on the Linux host. Firefox 134.0.2 mint-001 1.0. Linux Mint 22.1. Any ideas about what went wrong?

On the Save Page As dialog on Linux, how do I edit the choices of where to save?

The stock options are Home, Desktop, Documents, Downloads, Pictures, Videos, and + Other Locations.

I don't use most of these directories, but I do use two dozen others. Navigating to them using Other Locations is painfully slow; it would be ok if I could then save the location I've navigated to, but I haven't found a way to do that, and clicking one path element at a time for 6 element paths over and over gets old quickly.

Typing the path I want either nukes the default filename, or else it tries to match the filename string from the URL in the target directory, which doesn't show me existing directory contents.

Thanks for any clues...
