Reduce the memory footprint of the Firefox browser

In some cases, Firefox consumes more memory (RAM), causing the browser to react slowly and, in extreme cases, even cause the browser to crash. Here are a few ways to help reduce the memory footprint of Firefox, allowing you to use the Firefox browser more effectively.

Check for additional components installed

The installation of additional components, including extensions, themes, plug-ins, makes it more common for browsers to consume too much memory.

You can start the Firefox browser in safe mode and watch for memory usage. Extensions and themes are disabled in safe mode, so if memory consumption improves significantly in safe mode, you can try disabling or uninstalling some extensions.

In addition, Plug-ins (especially older versions of Plug-ins) often consume large amounts of memory. You can disable some of these plug-ins, and then look at the memory footprint after you restart the browser to determine if "excessive memory consumption" is caused by the plug-in. After you find a plug-in that consumes too much memory, disable it or upgrade it to the latest version.
To disable Plug-ins: Click the "Tools-Additional Components" menu, select the "Plugins" panel, select the plugin to disable, click "Disable", restart the browser can be effective.

　　Restart Firefox browser

You can free up some unnecessary memory usage by restarting browsing. You can choose to save the tabs and Windows before you close the browser so that the currently open browser window and page are saved when you restart.

　　Close unnecessary tab pages

Each tab will occupy a certain amount of memory space, it is recommended to close some unnecessary tabs, you can use bookmarks and other ways to better collect, manage the tab page.

　　Memory Troubleshooting Tool

Recommend two attachment components to help isolate memory leaks:

Leak monitor: Memory leak monitors. You can be alerted immediately when a memory leak occurs, and can help you find the cause of the vulnerability.

Ramback: Cache cleaner. Eliminates unnecessary caching and can effectively differentiate between caching and memory leaks
