Firefox browser will soon prevent the injection of DLLs from antivirus and other third-party applications.
Windows antivirus and other third-party applications, such as PDF tools, etc., are used to adding a DLL to the browser. This behavior is known to cause stability problems for browser users.
The Mozilla Foundation seems to be following the lead of Google which has started to block third-party code injection into Google Chrome as of 2018. Google found that Chrome installations that contained third-party DLLs had 15% more problems than Chrome installations that did not contain third-party DLLs.
According to gHacks the Mozilla Foundation has begun to investigate the disabling of third-party DLLs in Firefox in the fourth quarter of 2016, but as the decisions have already been taken.
Firefox Nightly already blocks the addition of third-party DLLs. The feature will later be integrated into the Beta and stable versions of the proletterof the Firefox browser, since version 66.
Firefox Beta will reach 66 on 29 January 2019, and Firefox Stable will release the 66 version on 19 2019 March.
How do you know if security mode is already enabled? It's simple: Open the internal address about:support and check the entry of dwork at the top.
It will indicate whether it is turned on or off.
If it is turned on and you want to disable the new feature (only available in Firefox Nightly), open the following internal address:
about: config? filter = browser.launcherProcess.enabled
Double-click and set the value to False.
Activating the feature may cause problems for third-party applications, which should update their applications up to the 66 version of Firefox to remove the DLLs they add to the browser.
