Comment on Letting users block injected third-party DLLs in Firefox by Hales

Hales — Sat, 01 Apr 2023 03:39:31 +0000

Thankyou for taking a nuanced approach to this, rather than a polar “no DLLs” or polar “who cares” view.

Disabling all DLL injection in the name of security would probably bring the opposite to many users in reality (who would then use a different browser, older version of Firefox or special builds).

It’s a shame that editing is neither a focus area nor an investigation this year. Otherwise, it looks like a nice list, and it seems like there’s a lot there.

> retry the failed memory allocation

So, is it true that mem allocation failures can be retried with a delay and that can be successful?

Nice article, as an operating system professor this was a really good article I can share with my students to learn about how Windows manages memory using a real-production case.

This was really cool to read. Congrats on the massive stability improvement!

After reading your description of how Windows handles memory and the real-life implications of it… I can’t help but think that the Windows way is a little bonkers.

Is there a good defense of why Microsoft’s way is “better”? Like, are there any upsides from a performance, stability, or other perspective?

Since about this version number my firefox acts weird on linux. Always after an update and sometimes just after a reboot, firefox won’t start. To be precise: It starts but no window opens. When I look at the task manager I see 3 firefox processes. Now I kill the 3rd process. Than only the first process remains and the window shows up immediatly. I guess there is no advantage without a disadvantage. :)

Liked your piece on memory management w/Firefox.

I would be interested if you did sone work on Mac OS and Linux. I don’t have any hard, concrete evidence, but I’ve seen memory issues that bring MAC OS to a standstill. Having said that, I don’t have the receipts to prove this. More importantly, my days as a developer are long since over… I’m still up for reading interesting technical issues re. the Mac and iOS platforms.

That is… clever. Interesting that Windows behavior is so much more obtuse here… I can’t quite decide if I like that behavior or it is something to add to the ‘why I should switch to Linux’ list.

I’ve noticed some considerable performance improvements over the last few releases of Firefox. Thanks for all effort here!

Instead of adding dummy content to it, you can make an empty initial commit with the –allow-empty flag.

In reply to Gian-Carlo Pascutto.

Update: After investigation, we determined that there was a window of time upon where Microsoft had a broken configuration file for Exploit Protection up (Windows 10 Version 1709 Security Baseline). That file has since been rescinded by Microsoft, but installations that are running the broken version will break on the Firefox 100 update. Getting an updated Exploit Protection Security Baseline setting from Microsoft here: https://www.microsoft.com/en-us/download/details.aspx?id=55319 should resolve the issue.

In reply to Tobias.

There are a number of known incompatibilities of Firefox with “Exploit Protection”, particularly if non-default settings are used: https://support.mozilla.org/nl/kb/compatibility-exploit-protection-windows-10

Note that Firefox by itself already includes most of these exploit mitigations that are known the be fully compatible with normal browser operation.

There is no known incompatibility with win32k Lockdown at this time. Because win32k Lockdown affects only the processes that render (untrusted) Web Content, missing the Settings menu seems to indicate another problem.

Can you file a bug in https://bugzilla.mozilla.org/enter_bug.cgi?product=External%20Software%20Affecting%20Firefox so we can investigate further?

We are using Microfoft Defender for Endpoint with exploit protection. Unfortunately Firefox does not work anymore since version 100. It starts but no websites are rendered at all. Also all about-pages or settings menu is not loaded.
We cannot see any blocked components of Firefox. Perhaps you have heard about these issues in combination with Microfoft Defender for Endpoint or similar products?
