    I've switched back to the Opera browser (v.10) recently, because Firefox 3.6 was taking up too much memory, and if I had more than a certain number of tabs open, it would crash.

    Besides, I love the new Opera browser. The find functionality now works similar to Firefox (it finds items on the page and highlights them, and even shades out the background so you can easily find the keywords you're looking for).

    Anyways, while Opera is working fine, it still appears to be taking up way too much memory (when I check the opera.exe process in task manager).

    So, anyone here know some tips for reducing Opera memory usage and consumption?

    Hi Jeff,

    There's several things you can do to reduce Opera memory usage. You'll want to experiment with these, and remember the settings you've changed, so you can switch them back on in the event that a website or web app stops working as a result of the setting change. Also, you can pick and choose which memory settings you want to change - you don't have to do all of them. They all save a different amount of Opera memory, and even making a couple of them should make a difference and help you run more Opera tabs at once without slowing down your PC.

    Reducing Opera Memory Usage

    • The first thing you'll want to do is adjust the appearance of Opera. You can turn off some fancy graphics settings to save memory. Click on the main Opera icon in upper left, and then select "Appearance" (or use the Shift + F12 keys). Change the "Opera Standard" skin to "Windows Native Skin."
    • In the same menu, deselect "Enable special effects". Hit OK to save your changes.
    • Next, open a blank tab and type the following in the Opera address bar: opera:config#UserPrefs. This will let you visit the main Opera configuration page, where you can adjust all kinds of settings (you may even find some other ones that you want to tweak, independent of the memory settings).
    • Use Ctrl + F (Find) to locate the following settings and disable them:
      - AutomaticRAMCache
      - Bittorent support
      - Cache > Empty cache on exit
      - Favicons (the little icons that appear in the tabs to identify web pages)
      - Java
      - Opera Sync
      - Page Index
      - Quicktime (this will only show up if installed)
      - Smooth Scrolling
      - Speed Dial
      - Thumbnails
      - Wand

    JeffNox I would just like make a comment on what you said:

    "The find functionality now works similar to Firefox (it finds items on the page and highlights them, and even shades out the background so you can easily find the keywords you're looking for)."

    Opera had these features first and Firefox copied them. Actually Opera also was the inventor of tabbed browsing. Check this website out: http://home.comcast.net/~SupportCD/FirefoxMyths.html

    Overzealous, are we? Don't you worry, Firefox has marketing which Opera never had and never will have.

    If you're on Windows, try minimizing Opera to the task bar. Windows reduces RAM usage for minimized applications.

    I also tried something else that worked for me: lock Windows then put the PC in hibernation/sleep mode for about a minute, then log back in. Opera's RAM usage typically drops noticeably on my machine.

    Which do you choose, hibernation or sleep mode since those are two totally different things? It takes a longer time for the pc to wake up from hibernation mode than from sleep mode.

    Thanks

    When I'm done with my PC for the day, I lock my PC and press the "hibernate" button on my keyboard.

    I would assume just putting your PC in hibernation without locking it would accomplish what I was referring to. I have also found setting disk cache to 400MB and memory cache to 40MB (instead of automatic) works well.
