However the good news is that Mozilla has announced that they will be rolling out the multi-process mode to more users in the future. The feature was launched several months ago but was limited to a handful of testers, but from what it sounds like, Mozilla reckons that the feature is now ready for primetime.
For those unfamiliar with the multi-process mode, basically this keeps the rendering engine of the browser separate from the frame itself. This means that in the event of a crash, only the tab that was affected crashes, instead of the entire browser. It is also done for security reasons where as ArsTechnica explains it, the rendering process can be kept in a low-privilege sandbox so that exploits are harder to take advantage of.
Mozilla has been slowly rolling out the feature for its users, starting with those who did not rely on browser extensions, before expanding to those with select extensions, and with the latest update it should roll out to more users and cover more extensions. If you’re a fan of Mozilla’s Firefox browser, then these changes are definitely worth looking forward to.
