Main new features of Firefox 63
With this new release of the Firefox web browser proposes a set of options to manage content blocking.
With which offers the user the possibility of enabling the blocking of cookies and third-party scripts used to track movements.
For each site in the address bar shows a special icon that shows the blocking status of scripts and cookies.
It is possible to add exceptions for the selected sites that cannot function properly when blocking the tracking scripts.
Now for the case of those using the web browser on Linux the execution of plugins based on WebExtensions was processed in a separate process (for Windows and macOS, a separate process for WebExtensions was already involved in Firefox 56 and Firefox 61).
Running in a separate process allows you to isolate add-ons and reduce the impact of add-on errors on browser stability.
Remember that previously, in separate processes, Firefox already rendered the content controllers, as well as the code to process graphics and access to local files.
