High RAM usage

Why Firefox using all of my memory. My PC 8GB RAM. Firefox uses 6GB RAM only for 1 tab? I only read manga at http://www.mangahere.cc/ if the ram is almost full, I have to restart Firefox. Why is RAM management in Firefox so bad? I'm tired of this, please fix it. If you don't believe it, you can test it by reading a random manga.

Why do I restart firefox when ram starts full. Because, if I don't restart, then the other programs that run will lag or hang. In other words, Firefox makes other programs to move to a virtual memory (page file).

I hope I can limit firefox to use RAM (for example 3GB).

More than one process is normal for the current Firefox. http://www.ghacks.net/2016/07/22/multi-process-firefox/

Multi-process Firefox is codenamed "e10s". https://wiki.mozilla.org/Firefox/multiprocess


Try to disable multi-process tabs in Firefox. You can disable multi-process tabs in Firefox by setting the related prefs to false on the about:config page.

browser.tabs.remote.autostart = false browser.tabs.remote.autostart.2 = false

Type about:config<enter> in the address bar. If a warning screen comes up, press the I Accept the Risk button. At the top of the screen is a search bar.

Don't you understand my question? This is not a process problem, but a RAM management problem. And I've tried everything you said. And that doesn't work.

I am also not a beginner, I have also searched for solutions before writing on the support forum here. Why don't you try visiting http://www.mangahere.cc/ and reading something manga, and open up to hundreds of pages. And look at Firefox's RAM management is very bad.

You can check the about:memory page what is taking up this memory. There are also butons on this page to reduce the memory. You can open "about:" pages via the location/address bar

  • "about:" is a protocol to access special pages

See also this tool that is part of the developer tools.

..............

about:memory that doesn't solve the problem. And why should I bother checking about:memory, if I already know what is taking up this memory. And other users also experience this problem: https://support.mozilla.org/en-US/questions/1223605#answer-1153853 Please fix it, don't give me a stupid answer.

Do you use any addons? As I can see you are using Adblock Plus

Have you tried the Performance settings (see image) to see if that would help? I probably have about 1,000 Tabs going across 6 Windows right now. Notice my Memory usage (see image). I do have a Modified Tab setting in About:Config where only one Tab per browser window opens at FF startup (resume sessions). I have one browser window (my main one I'm now using) with over 800 Tabs going. Again, they're not all loaded - only the ones I go back to visit load-up. This helps a lot if one has a great many of Tabs going.

Seeing that you have a problem with very few Tabs open, something is amiss in your setup, be it some other Windows program conflicting (Anti-Virus - temporarily turn off to test) or one or more browser Extensions.

(Edit: I also have a special 0 Disk-Cache/More Memory Cache setup going, but this is a last thing to try item for those interested if all the other methods here on this site don't help enough.)
