Serious Mozilla Firefox problems

[spirkov]

Hi after last updates I meet serious problems with my Mozilla Firefox, I can't figure out where's problem and this become totaly annoying and slows me down like 30% with my jobs.

When I open several windows (tabs) in Mozilla and does Packing (winrar) or listening some music on "youtube", my Mozilla take 60-85% of my CPU usage witch is simply terrible to use machine on that i can't change windows without 3 sec delay. Also after some time i can't use "Right click" on any place under Mozilla window. Can't save picture, cant open some hyperlink on new location or simple things like that, can't even close "Download" Mozilla window.

I have tried reinstalling Mozilla, and defrag my main drive. I'm virus free, and my config is

AMD Athlon 5200+ (2x2MB Cache)
8GB DDR2 1333 Mhz
3x 650GB Seagate (several out) around 300GB space on main c:/ drive
WinXP with latest updates

Problems started after last Mozilla updates.

Hope someone know to help me with this peace of ....

you just need to Reduce Firefox Memory and Cache Usage
it work gread for me

Tip 1: Reduce session history
browser.sessionhistory.max_entries  determines the maximum number of pages in the browser?s session history, i.e. the maximum number of URLs you can traverse purely through the Back/Forward buttons. The Default value is 50.
We usually won?t surf more than 5 of the websites we previously surfed before, and there is really no need to store more than that in the session which can clog up memory as they grow.
1. Open Firefox
2. Type about:config in the Firefox address bar
3. Press CTRL-F and search for browser.sessionhistory.max_entries 
4. Double click on the value 50 (or whatever value is there currently) and change it to something lower such as 5.
5. Restart Firefox.
 For Firefox 1.5 and above, you can also look at another configuration variable browser. sessionhistory. max_total_viewers which also determines the maximum number of content viewers to cache for ?bfcache? (fast back/forward navigation). Default value is -1 (calculate based on available memory).
Set it to 0 so that no pages will be stored in memory.
set it to a number such as 5 to store only 5 pages in memory.
more info here 
 Tip 2: Reduce memory usage when minimize
1. Start up Firefox
2. Type in about:config in the address bar and hit Enter
3. Right click and choose New > Boolean
4. Type config.trim_on_minimize in the pop-up box and hit Enter
5. Select True and hit Enter.
6. Restart Firefox
 Tip 3: Fixed cache capacity OR Disable Cache Totally
Every time new page is loaded, Firefox will cache the page so it doesn?t need to load again to be redisplayed. By default, this setting is set to -1 for browser.cache.memory.capacity and to a number you specified in Tools -> Options -> Advanced -> Network / Cache for browser.cache.disk.capacity 
 To fix your cache to a certain value:
*browser.cache.memory.enable and browser.cache.disk.enable needs to be True for this to work
1. Start up Firefox
2. Type about:config in the address bar and hit Enter
3. Search for browser.cache.memory.capacity and set a number in KB to use for the memory cache (ie. 1024KB = 1MB).
4. Search for browser.cache.disk.capacity and set a number in KB to use for the disk cache (ie. 1024KB = 1MB).
 To Disable the cache Totally
Set both browser.cache.memory.capacity and browser.cache.disk.capacity to 0.
Alternatively, you can also set browser.cache.disk.enable and browser.cache.memory.enable to False. 
 Tip 4: Use less extension and themes
This is really a no brainer. Uninstall all firefox extensions and themes that you don?t use as they can cause Firefox to use more RAM. If you think that you might still need the extension in future but not using it currently, at least there?s an option to Disable it. Use only extensions that you usually use to cut down memory usage. 
 Always upgrade your extensions and themes to the latest version as they may fix the some problems leading to memory leaks. Firefox makes this quit easy as it now does the checking for you, all you need is to do is tick some checkboxes and your plugins and themes wil be updated.
 Tip 5: Check Firefox Memory Usage
Type about:cache?device=memory in the address bar and hit Enter. Firefox will display your current number of entries, maximum storage size, storage in use and inactive storage.
 There you have it. Happy browsing!
