How to reduce Firefox memory usage

Turn off extensions that aren't needed at the moment.

Dear users, hello! We'll be happy to answer your questions.

The so-called Firefox Speed Mode is an extension that can support direct internal switching of the Firefox browser kernel to define the kernel modes of different browsers. As shown in the figure below:

The so-called "no need to save, directly occupy memory" refers to the working mode of the browser, which is completely determined by the default configuration of the browser, and no configuration items are provided. However, you can do this by installing ramdisk (a software that partitions a virtual hard disk in memory) on your system, then placing Firefox on the virtual hard drive, and specifying the cache and other locations there.

I hope I have been helpful to you, and if you have any questions, please feel free to continue to consult us.

How to deal with the large memory usage of Firefox:

1. Go to the browser options settings to clean up the browser cache junk.

a. Play **Fox Browser, click the three horizontal line buttons in the upper right corner to enter the options.

b. Click "Privacy" on the left to clean up the cache garbage.

2. There are too many programs running on the computer at the same time, resulting in too high memory occupancy. Terminate other running programs via Task Manager; Or increase your computer's memory.

3. The computer itself has too much garbage cache. Use the computer manager or guard installed on the computer to scan and clean up the garbage.

If you're very tight on memory, you can try lowering the memory expansion.

However, in order to ensure the user experience, the browser needs to occupy a certain amount of memory to cache the content of the web page, and you can read it from the memory when you browse the same web page again, improving the efficiency of the browser.

Real-time cleaning of memory will cause excessive CPU usage, increased hard disk and network data reads, reduced web page access speed and other drawbacks, Firefox has actually included memory auto ** mechanism, effectively reducing memory usage.

Open a web page, close the previous one

IE opens an empty window and occupies 8544KB of memory, which increases as you browse different web pages. At its peak, it will reach 30,000kb, which really makes people feel that IE is a big eater of memory.

When Maxthon was first launched, the window occupied only 3900KB of memory, which was less than 4000KB. However, as the web page is loaded, the memory also increases, reaching 23000KB at the highest time, which is only a little less than the memory occupied by the IE browser.

Single window: Mozilla Firefox occupies 17800KB of memory when opening a window, and 28000KB after loading a web page, which is okay for the overall amount of memory.

Multi-window: Mozilla Firefox opens 5 Mozilla Firefox windows, which occupies about 100,000KB of memory. If you open 10 windows for 200,000kb, it is also a big memory eater.

Opera uses about 14,000 KB of memory to open a window, and after loading a web page, I found that there is no significant change in memory usage, which is significantly different from other browsers.

Multi-window: The memory occupied by opening 5 windows with Opera is 55000KB, which is decent. When opening 10 windows, it is 75000kb, which shows that Opera is still very memory saving when opening multiple windows.

I'm sorry.,I haven't used opera.,Because I don't usually go online.,Occasionally.,Just use IE.,This answer is my own collection.。

Follow these steps to check the cause of the abnormal memory usage:

1. Check the add-ons and themes.

Firefox has a lot of add-ons and themes installed, so organize them and remove any that you don't use or don't need. You can open Firefox in safe mode to check it, here's how to do it:

1. Close the Firefox browser.

2. On the desktop, click "Start" > "Run".

3. Enter "firefox -safe-mode" and click "OK".

Figure 2 Enter firefox-safe-mode

4. At this time, you will see a new window called "Firefox Safe Mode".

Figure 3 The Firefox Safe Mode window.

You can select the options that appear here, and if you click "Save changes and start over", Firefox will apply the changes and start in normal mode. If you select "Continue using safe mode", then no settings will be applied. If you select "Opt Out", you will exit the browser without any settings being saved.

2. You need to make some changes to the settings of your browser. Please open the Firefox browser.

3. In the menu bar, click "Tools" > "Options".

In some cases, Firefox can take up a lot of RAM, causing the browser to react slower, and in extreme cases, even crashing the browser. Here are a few ways to help reduce Firefox's memory footprint and allow you to use Firefox more efficiently.

Check the installed add-ons.

It's not uncommon for installed add-ons (including extensions, themes, and plug-ins) to cause your browser to take up too much memory.

You can launch Firefox in safe mode and observe the memory usage. Extensions and themes are disabled in Safe Mode, so you can try disabling or uninstalling some extensions if your memory footprint improves significantly in Safe Mode.

In addition, plugins, especially older versions, often consume a lot of memory. You can disable some of these plug-ins and observe the memory usage after restarting the browser to determine whether the "excessive memory usage" is caused by the plug-ins. Once you've found a plugin that's taking up too much memory, disable it or upgrade it to the latest version.

How to disable the plug-in: Click the "Tools-Add-ons" menu, select the "Plug-ins" panel, select the plug-in you want to disable, click "Disable", and it will take effect after restarting the browser.

Restart Firefox.

You can free up some unnecessary memory usage by restarting your browsing. You can choose to save tabs and windows before closing the browser so that the currently open browser windows and pages are saved when you restart.

Close unnecessary tabs.

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 and manage tabs.

ramback: cache cleaner. Unnecessary caches can be cleared and caches can be effectively distinguished from memory leaks.
