By release of Firefox 54 last week, the process of disposing of multi-tool electrolysis or multiprocess was finally completed Electrolysis.
Since its latest release, Firefox can use up to four processes, so users of the popular browser can have better memory usage and, of course, better performance.
However, users who have been using Mozilla's browser for years can be disappointed when they find that their browser works in a single process.
If this is the case for you, the culprits are the add-ons you've probably been using for years.
To check if Firefox 54 uses a single process, you can check the operations of your operating system or check if the browser value associated with the internal configuration of dom.ipc.processCount in the firefit's about: config is set to 1 .
If you notice any of the above, it's time to look into Firefox add-ons to see which ones extension it gives the error.
Firefox provides little information at this time, but if you install the extension Add-on Compatibility Reporter you will see a lot of information in Firefox's Expansion Table.
In the top right corner there will be a label indicating whether the multiple process is activated or not. Below you will see a list of all your extensions and a tag indicating whether or not they are compatible with electrolysis.
What you will do below is up to you:
If you disable incompatible extensions, then the multiple process in your browser will be enabled, but you may also need to change the value of dom.ipc.processCount as I did.
Alternatively, you can continue to run your browser with a single process if you absolutely need a specific one add-on, knowing that with Firefox 57 coming out in November, all extensions will be ported to WebExtensions.
