Get rid of that yahoo search in firefox

I was unable to change the search engine in my Firefox. I had changed it several times but the next time with all the surprises I would see it reverted back to the default Yahoo search, that is actually not useful to me. I found it very annoying though. Anyway I did some googling to find a way out, but not that useful! so here is a solution finally got me out of it.

1- open firefox and enter "about:config" in the address bar. here you can see the configuration parameters.

2- search the word "yahoo"in the search box in upper part search bar.

3- change the value of the parameter "browser.search.defaultenginename" to "Google".

4- change the value of the parameter "searchreset.backup.browser.search.defaultenginename" to "Google".

5- change the value of the parameter "searchreset.backup.keyword.URL" to "http://www.google.com/search?lr=&ie=UTF-8&oe=UTF-8&q=&#8221".

6- done!

Yahoo search is not that bad but I personally prefer Google, beside when you want to do some search in Persian, it just sucks man! but in return Google handle it very good. so why should I use Yahoo!

firefox: resolving memory leak issues

Yes, firefox is a great browser. But it has some memory management issues. I mean there is a memory leak (or garbage memory) problem. It means that firefox consumes memory without any use. even sometimes you can see in the Windows Task Manager that the Mem Usage of firefox in the Processes tab is increasing constantly!!!

There is a simple solution that doesn't fix it completely, but makes it better to some extends. This is not a fix for memory leak but it affects it. It will move firefox to your hard drive when you minimize it, and as a result it will take up less than 10mb of memory while minimized. this is one of the options in the firefox that does not included in the standard user interface. so if you want to enable it, follow the instructions bellow:

1- in the address bar type "about:config" and press enter. by doing this you can access to varable configuration console. it's something like windows registry.

2- right click somewhere on the page and select new boolean, and in the poped up window type "config.trim_on_minimize" and then press enter.

3- now select True and then press enter again.

4- now restart firefox and it's done!

if you are interested to working or understanding about About:config entries, there is a good reference and here is a link:
