Firefox 3.0 RC 2 v/s Firefox 2.0.0.14.

The numbering pattern for Firefox 2 (2.0.0.xx) made me think that there might be innumerable versions before we get to see Firefox 3.0. But thankfully Firefox has been working on betas for version 3 for long and we have seen some of the features meant for 3.0 enter the stable versions too.
After Firefox launched the second release candidate,
(news:

I ran a test to see if there is a difference in memory usage.
Now this test should be flawed because of many many reasons, but still here it is.
Firefox 3.0 RC2
1. Just Loaded: Memory: 29K
(I was typing start in the address bar, which might hav caused a slight spike, but the memory was near 29K before I began typing)

2. 10 Start Tabs: Memory: 33K

3. 10 Start Windows(from the earlier 10 tabs, 9 were closed and 9 more windows with home page were opened ); Memory:44K

4. Back home after closing the other 9 windows:Memory 36K

5.Searched for a video on youtube.com. Let it load fully. Then Played. Memory:50K


Firefox 2.0.0.14
1. Memory: 21K

2. Memory: 25K

3. Memory: 35K

4. Memory: 29K

5. Memory: 39K (Spiked to 50K while the movie was loading, but came down afterwards. Both rc2 and 2.0.0.14 were tested after the movie loaded completely!)


Now a million of such tests should have been run. Plus more scenarios should have been tested. Then a mean should have been drawn to interpret the results. But since I didn't do that. here is a comparison

Step No. Firefox 3.0 RC2 Firefox 2.0.0.14
Step 1: 29K 21K
Step 2: 33K 25K
Step 3: 44K 35K
Step 4: 36K 29K
Step 5: 50K 39K

Conclusion: Don't worry about the memory(It's cheap anyways!) Firefox 3 looks better and they say that it has electrolytes!

For serious people: Acid3 test results for Release candidates have been good
( >70/100 ). I didn't test one myself, but I did test my 2.0.0.14 got a 54/100.
Test your browser too

(PS: I tested my IE7. The test result was incoherent(even after enabling activex)!Perhaps acid is for Firefox only)

  1. The test was carried out on the same system, both firefox installations were standard. Both had all add-ons disabled.
