Optimized Storage helps you save storage space space by storing your content in iCloud and making it available on demand:
The OneDrive app on my Mac, running macOS High Sierra, is using an excessive amount of memory (1.42 GB!!) even when there is no file activity at all going on. Dropbox is usung a lot if RAM- about 350 MB and my computer runs very slow, and is difficult to use. Dropbox uses 5 or 6 times more RAM than any ither program, even after using SmartSync on mist if my files. If there is mostly green, your system RAM is currently fine. If there is a lot of yellow, the jury is still out. If there is a lot of red, your memory is under strain and your Mac has a high memory usage. Older OS X versions like Leopard and Lion. For older versions of Mac OS X the steps are the same but the System Memory tab looks a bit different.
- When storage space is needed, files, photos, movies, email attachments, and other files that you seldom use are stored in iCloud automatically.
- Each file stays right where you last saved it, and downloads when you open it.
- Files that you’ve used recently remain on your Mac, along with optimized versions of your photos.

- The Storage pane of About This Mac is the best way to determine the amount of storage space available on your Mac. Disk Utility and other apps might show storage categories such as Not Mounted, VM, Recovery, Other Volumes, Free, or Purgeable. Don't rely on these categories to understand how to free up storage space or how much storage space is available for your data.
- When you duplicate a file on an APFS-formatted volume, that file doesn't use additional storage space on the volume. Deleting a duplicate file frees up only the space required by any data you might have added to the duplicate. If you no longer need any copies of the file, you can recover all of the storage space by deleting both the duplicate and the original file.

At times, Firefox may require significant system resources in order to download, process, and display web content. If you are experiencing periods of sustained high resource usage while using Firefox, this article presents some options for you to review.
- The CPU (Central Processing Unit) is the 'brain' of the computer.
- The RAM (Random Access Memory) or Memory helps your computer perform multiple tasks at the same time.
- When your system resources are being heavily used, the overall performance and stability of the computer can be impacted.
- Depending on your operating system, you can review and monitor resource usage through specific tools. See the Use additional troubleshooting tools section below for more information.
Note: If you send performance data, Mozilla will gather data including memory and CPU usage, which will help make Firefox better for future versions.

The latest Firefox version may include performance improvements. Update Firefox to the latest release.
Firefox may use more system resources if it's left open for long periods of time. A workaround for this is to periodically restart Firefox. You can configure Firefox to save your tabs and windows so that when you start it again, you can start where you left off. See Restore previous session - Configure when Firefox shows your most recent tabs and windows for details.
Extensions and themes can cause Firefox to use more system resources than it normally would.
To determine if an extension or theme is causing Firefox to use too many resources, start Firefox in its Safe Mode and observe its memory and CPU usage. In Safe Mode, extensions and themes are disabled, so if you notice a significant improvement, you can try disabling or uninstalling extensions.
- For more information on starting Firefox in Safe Mode and on how to find which extension or theme is causing your problem, see Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems.
Many web pages have content you don't need, but which still use system resources to display its content. Firefox's built-in content blocking can help save resources by preventing third-party tracking content from loading. See the Content blockingEnhanced Tracking Protection article for details. Livescribe app for windows 10.
Some extensions allow you to block unnecessary content; for example:
- Adblock Plus and uBlock Origin allow you to hide ads on websites.
- NoScript allows you to selectively enable and disable scripts running on websites.
If Adobe's Flash Player plugin is installed, rendering Flash content in full screen can be accelerated by hardware. This can ease resource usage in case of a dedicated graphics card.
- Navigate to a page that shows a Flash video.
- Right-clickHold down the Ctrl key while you click on the video player and click Settings… in the context menu. The Adobe Flash Player Settings screen will open.
- Click on the icon at the bottom-left of the Adobe Flash Player Settings window to open the Display panel.
- Check Enable hardware acceleration is selected.
- Click to close the Adobe Flash Player Settings Window.
Each tab requires Firefox to store a web page in memory. If you frequently have more than 100 tabs open, consider using a more lightweight mechanism to keep track of pages to read and things to do, such as:

- Bookmarks. Hint: 'Bookmark All Tabs' will bookmark a set of tabs.
- Save web pages for later with Pocket for Firefox.
- To-do list applications.
Firefox hardware acceleration eases memory and CPU usage in many cases.Check in Firefox's performance settings that hardware acceleration is turned on. Also make sure that your graphics drivers are up-to-date.
With Multiprocess Firefox, also called electrolysis or e10s , Firefox runs web content for all tabs separately from the main Firefox process for increased security and performance. Using multiple content processes can further increase performance and minimize the impact of content process crashes. You can modify Firefox's performance settings to change the content process limit.
You can set between one and eight content processes. The default is eight. Having more content processes can improve performance when using multiple tabs but it will also use more memory. You can reduce the number of content processes if your computer is running out of memory.
Having many applications running simultaneously may cause your computer to run slowly and other applications to do so as well. By closing down some of the unnecessary applications, system usage will be reduced.
Firefox stores your data in various files in your profile folder. The file used for saving individual website settings might be corrupt. If you delete (or rename) that file, your zoom level settings will be reset but it could decrease CPU usage.
- Click the menu button , click Help and select Troubleshooting Information.From the Help menu, select Troubleshooting Information. The Troubleshooting Information tab will open.
- Under the Application Basics section next to Profile FolderDirectory, click . A window will open that contains your profile folder.Your profile folder will open.
