Firefox 7 Might Solve Memory Fragmentation IssuesAccording to the discussion participants at Bugzilla.Mozilla.org, Firefox 7 might include a patch to solve at least some of the memory bloat issues.

After the initial testing, it does look promising.

Here are the results:

After closing all tabs, but before minimizing memory usage:
506,326,510 B (100.0%) — explicit (without patch)
454,850,070 B (100.0%) — explicit (with patch)

239,075,328 B — js-gc-heap (without patch)
189,792,256 B — js-gc-heap (with patch)

Before minimization:
550,207,488 B — resident (without patch)
494,604,288 B — resident (with patch)

After minimization:
310,890,496 B — resident (without patch)
219,856,896 B — resident (with patch)

That’s quite a difference! Whether or not patch lands in Firefox 7 remains to be seen.

    A browser is improving! That’s always good news :)

    Haven’t Mozilla been promising this for years?  Every time it never delivers, and all the while, they load things down with additional bloat to compound problems?
    It seems this is more about positive PR than actually fixing things.

      Unfortunately they still fail to fix this.

      even if this only compensates some of the things they did wrong in the past years it is a positive patch that will help making the browser more user-friendly, light and slim. 

      And I say this without even thinking of using Firefox again (Opera forevaaaaar! :-P )

    Any improvement is always good, but this has taken too long.

    Are they sure they didn’t fix it already??? I’m using firefox 7 nightly and I don’t notice any leaks or is it me cause I’m not a good observer at all. At least the CPU is kind a low. Well whatever.

    “…to solve AT LEAST SOME of the memory bloat issues…”
    I’ll better wait for firefox9 to see if this completely solved
    And I don’t have to worry. Maybe we’ll have firefox15 by the end of the year

    Memory usage on Nightly has been great for me. Much better than Chrome.

    Now all the browser & media stopped talking JavaScript performance and area of problem in today’s modern browsers are memory usage. Good to know.!!

    Firefox 7 completely stops my computer from working, even for non-web word processing.  The memory usage is astounding.  My cursor switches to sand so nothing can be accomplished while Firefox eats my computer.

    Oops.  It’s Firefox 6 that doesn’t work.
