NoScript, the one must have add-on for Firefox if you ask me, has received an update recently that introduces full multi-process compatibility (e10s).
This paves the way for enabling Firefox's multi-process architecture if NoScript is installed.
Mozilla is still in the process of enabling Firefox's multi-process architecture on systems running the stable version of the browser.
One main reason for spreading the enabling of the feature over several releases is that not all add-ons are yet compatible with the architecture.
To avoid incompatibilities and monitor the situation better, multi-process Firefox has been enabled for Firefox installations without add-ons and Firefox installations with safe add-ons only up until now.
The next step is to enable it for Firefox installations with add-ons that are not explicitly marked as incompatible with the multi-process architecture. Mozilla runs a test on Firefox Beta currently to monitor this.
NoScript Security Suite is one of the most popular browser extensions for Firefox. It has a five star rating over at Mozilla and is used by 2.15 million users.
The changelog on the official NoScript website highlights the improvement:
Full e10s compatibility
Fixed big whitelists being reset to default permissions on
Fixed some pages not loading on 1st attempt when e10s is
What this means is that NoScript will play fine with Firefox's new multi-process architecture, and should not block it from being enabled by default any longer. NoScript users can use the extension if e10s is enabled in Firefox. While there is still a chance for bugs, the general implementation is stable so that most NoScript users should not experience any issues with multi-process enabled.
Mozilla's own Are We e10s yet website provides you with information on add-on compatibility. According to the site, about 2100 add-ons are known to be compatible, while only 19 are incompatible.
While that sounds good, there is this large chunk of 16900 add-ons that are listed as unknown. Unknown means that they have not been verified yet or reported by users who run the add-on compatibility reporter.
NoScript 2.9.5 ships with several other improvements on top of multi-process support that are worth mentioning:
