Firefox just crashes sometimes. This is very annoying as it can happen multiple times a day.
 This might be the same bug as https://bugzilla.mozilla.org/show_bug.cgi?id=1764975 or https://bugzilla.mozilla.org/show_bug.cgi?id=1764979 … ?
Here FF stopped playing any audio some time before crashing, so I filed a separate bug.

Maybe Fission related. (DOMFissionEnabled=1)

The whole browser freezes for 10 or more seconds, and after that runs normal again until next freeze.

Bug: Possible download files like exe to user Startup folder on windows, which may cause RCE
Status: VERIFIED
Priority: P1
Resolution: FIXED
Created: 2022-04-16 15:15:55+00:00
Resolved: 2024-05-30 17:55:40+00:00

Steps to reproduce:

Pre Requirements:

1. Settings → Files and Applications → Downloads → “Always ask you where to save files” is checked
2. Environment Variable: %HOMEPATH% resolves to \ . See link: https://docs.microsoft.com/en-us/troubleshoot/windows-server/networking/variables-resolved-incorrectly , when user's home folder is on a DfS share, %HOMEPATH% should resolve to \. Besides that, in some companies, IT department will configure their employee’s computer home directory to a network driver, which will also result in %HOMEPATH% resolving to \. See link:
    1. https://superuser.com/questions/255776/overriding-homedrive-and-homepath-as-a-windows-7-user/
    2. https://superuser.com/questions/246731/how-do-i-change-homedrive-homepath-and-homeshare-in-windows-xp
    3. https://stackoverflow.com/questions/40077826/windows-10-system-environment-variable-path-back-slash-meaning
    4. ...

Steps:
1. Run the app.py: python app.py. Note: I didn't attach calc.exe in the attached file: firefox-startup-poc.zip 
2. Visit the http://127.0.0.1:5000/, by holding for 2 seconds ENTER button on the website, the hacker can trick the user download a file like exe to his Startup folder, which will lead to RCE when system reboot.

Details:
<a id="link" href="/poc.exe" download="%APPDATA%%HOMEPATH%Microsoft%HOMEPATH%Windows%HOMEPATH%Start Menu%HOMEPATH%Programs%HOMEPATH%Startup%HOMEPATH%poc.exe">POC</a>

HTML <a> download attribute accept “%” in the file name, when the file save dialog show up and user click “Save”,  %APPDATA%%HOMEPATH%Microsoft%HOMEPATH%Windows%HOMEPATH%Start Menu%HOMEPATH%Programs%HOMEPATH%Startup%HOMEPATH%poc.exe will be resolved to  C:\Users\{username}\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup\poc.exe 

Another attack scenario
User has python installed and “PYTHONPATH” is configured to a path ends with backslash(\). For example: PYTHONPATH=C:\MyPYTHON\. For more details about PYTHONPATH, see link: https://bic-berkeley.github.io/psych-214-fall-2016/using_pythonpath.html

Python imports should be grouped in the following order:

1. sys.modules
2. built-in modules
3. import path: sys.path A list of strings that specifies the search path for modules. Initialized from the environment variable `PYTHONPATH`, plus an installation-dependent default.

So if we put string.py under the %PYTHONPATH% directory, it will hijack the “import string”.

<a id="link" href="/pystr" download="%PYTHONPATH%string.py">POC</a>

If user’s PYTHONPATH is configured without endings with backslash, we can still concatenate %HOMEPATH% to attack.

<a id="link" href="/pystr" download="%PYTHONPATH%%HOMEPATH%string.py">POC</a>


Actual results:

Website can trick user download file to startup directory, which may cause RCE.


Expected results:

% should be stripped in the file save dialog.

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:99.0) Gecko/20100101 Firefox/99.0

Steps to reproduce:

With two Firefox Windows open I allowed Windows to update and restart.

After the restart a Firefox start opens with just the Welcome to the latest Firefox page.

I close the page and so with no tabs to display Firefox exits.

BUT when I start Firefox again, ...


Actual results:

... I have lost my previous sessions, since there is now a useless previous session containing the Welcome page.


Expected results:

The previous sessions should not be trashed, particularly by the welcome page.

Perhaps provide a deeper stack of restorable windows.

Perhaps provide a deeper stack of restorable sessions.

Perhaps special case the Welcompage as not-a-useful session.

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:99.0) Gecko/20100101 Firefox/99.0

Steps to reproduce:

- create and open new profile
- set to "use custom settings for history"
- uncheck remember browsing history
- bookmark anything with CTRL+D except the privacy notice page firefox opened (or if this isn't a new profile then any site you've been to before disabling history)

Note that once you get the favicon that url won't reproduce the bug if you delete the bookmark and try again, and sometimes this carries of over to a site's other urls.



Actual results:

Favicons on the created bookmarks are the generic grey sphere favicon  untill you revisit the page then you get the actual favicon.


Expected results:

When you create a bookmark with CTRL+D the bookmark has a favicon, rather than only getting one if you refresh or revisit the page.
Bug: dragging tabs using pen/eraser on touchscreen causes error exit of Firefox with MOZ_ENABLE_WAYLAND=1
Status: UNCONFIRMED
Priority: P5
Created: 2022-04-17 05:29:11+00:00
Resolved: 2023-02-01 13:48:01+00:00

I have the environment variable MOZ_ENABLE_WAYLAND=1 to enable the Wayland support in Firefox, this issue doesn't happen when I remove this environment variable.

The Thinkpad X201 Tablet is a laptop that has a touchscreen with pen, eraser and finger input. I am running Debian 12 bookworm on the laptop and I'm using GNOME shell Wayland version 42 as a desktop with both Firefox 99 and Firefox ESR 91 from the Debian bookworm/unstable apt repositories. I normally use Firefox ESR, so would appreciate it if any patch to fix this issue could be backported there too.

When I use the pen or eraser to try and move a tab to the left or right, Firefox exits immediately and prints errors on the terminal. Firefox 99 also pops up a crash reporter error message dialog. There are no core dumps generated.

The issue doesn't happen with the finger input of the touchscreen, which simply does not do anything with Wayland mode enabled (but does without that enabled).

This is the error in the terminal with Firefox 99:

    (Firefox:284037): Gdk-CRITICAL **: 12:58:58.413: gdk_wayland_window_get_wl_surface: assertion 'GDK_IS_WAYLAND_WINDOW (window)' failed

    Details: The application didn't leave an application data file.

Expected results:

It should have opened thunderbird.
If the changes in windows 11 are a problem then Firefox should provide an independent mechanism for specifying the default mailer that does not rely on Microsoft. It kind of violates the whole point of "open source software" if you tie it so tightly to proprietary apps that it prevents users from doing what they want/need to do.

I'm going to classify this a a defect report since it used to work and no longer does. If it's not a defect (cough) then it is an urgent feature request but, from the users perspective, it sure feels like a defect
