@vrnoormd, are you using any special features of Opera such as Mail/Chat, newsrooms, Voice? If you do, try and create a parallel install (both Opera 8.5.1 and Opera 9 preview on different folders) and browse regularly with one and use the other for the special feature.
If not, you might try to clear your cache, startup with a blank page, surf without Java support, and ensure the pages you're visiting aren't auto-reloading too frequently. Something may be leaking memory, so keep an eye on Opera's memory usage when you notice your system slow-downs.
Likewise, you might try limiting Opera's memory cache to something static (~40MB) instead of Automatic (via Preferences > History and cache > Memory cache). Test if any plugin is causing problem by disabling one by one.

FireFox is taking lead day by day. Opera 8 has bugs and has become less efficient.
Lets parse this part by part:
1. Firefox is taking lead day by day: - I think Firefox was in the lead for a long time. IE is still at the top, doesnt make it a better browser.
2. Opera 8 has bugs: Sure, but so does Firefox... In fact, being open-source allows people to find the bugs in Firefox faster... But not necessarily fix them faster. If you look at
www.secunia.com you will notice that only 1 unfixed (Least Critical) security vulnerability is reported in Opera whereas there are 3 (Less Critical) security vulnerabilities in Firefox..
3. Opera has become less efficient: Take a look at *www.howtocreate.co.uk/browserSpeed.html - you will notice (a) With each new release, speed has increased in Opera and (b) All releases are faster than Firefox in most cases.
And finally, what exactly is your point in your post? Its not like the thread subject was which browser to choose or had anything regarding Firefox... It was a question regarding Opera... Please dont start a browser war in this thread...
