The Firefox browser will soon prevent DLLs from being injected by antivirus and other third-party applications.
The antivirus Windows and other third-party applications like PDF tools etc. tend to add DLLs to the browser. This behavior is known to cause stability issues for browser users.
The foundation Mozilla appears to be following the lead of Google which started blocking third-party code injection in Google Chrome starting in 2018. Google found that Chrome installations that contained third-party DLLs had 15% more problems than Chrome installations that did not 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 is already blocking the addition of a third-party DLL. The feature will be later integrated into the Beta and stable versions of the Firefox browser from the 66 version.
Firefox Beta will reach 66 on 29 January 2019, and Firefox Stable will release the 66 version on 19 2019 March.
How to know if the feature is already enabled security; It's simple: Open the internal about:support address and check the processes entry 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
Do double click and set it price 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.
