Firefox 2 Memory Usage


Recommended Posts

I have been running Firefox (no closes) for about 2 weeks now, straight.

It bounces from 55,000 to around 95,000K (average of 5 to 7 tabs open)

143M with just this page open.

I don't know why memory usage on mine is so high, but I don't care. I have 2GB RAM in my laptop :D

If ya got the RAM, why not use it? lol.

Well, out of all the whining and crying about firefox memory usage I've read on countless forums, I've yet to see one single person come up with reproducible steps that start with:

1. Make New Profile.

Also, anyone who disables the extension compatibility check or forces 1.5 extensions to work in 2.0 by using MR Tech's extension or Nightly Tester Tools looses all rights to moan if firefox eats memory... ever consider there's a reason WHY the extensions you had to force to work in 2.0 haven't been updated properly and resubmitted to addons.mozilla.org?

I've just got one Add-on for Google Bookmarks. Add-ons or no add-ons, mine starts with about 20MB. Reaches about 190MB, after opening and closing about 40-50 tabs in all, at the end of the day and that is when I have to restart it and start a new session because it becomes unstable - starts using 100% CPU for opening and closing tabs and takes over 3 seconds - and sometimes crashes. I had the same problem with 1.x.

My guess is, poor or no garbage collection; either by plug-ins like Sun Java, Adobe Flash and Adobe Reader or FF itself. The reason I'm saying this is because the memory usage doesn't decrease when I close tabs, even for pages without embedded items. It remains the same. I'm not in the development team; so, I don't know for sure what they're doing caching unwanted pages in memory. Well anyhow, FF2 is handling the plug-ins much better than what it did in 1.x, in terms of loading.

Though, Firefox 2 restores sessions after crashes or abnormal terminations, I didn't like it much because it loads everything again from the source and not from the cache. Hope this will be improved in later versions.

Mind you, IE7 is worse. The above things about memory management also go for IEx. Even Opera does a fair job keeping memory usage high without reason, but it handles things better than FF and IE7, as can be seen from the statistics provided by Shadowdruid (Post #9).

No browser is perfect. I use them all for different purposes, like keeping myself signed-in into a network without entering login information every time, money transactions, etc.

The whole idea about getting more memory is logically incorrect.

1 Everyone can't buy/use 2-4 GB of RAM

a) because there aren't as many slots.

b) the slots are already used up.

c) can't spend that much for RAM as everyone's not rich.

d) the motherboard can't handle that much memory, which means we need to upgrade, which means we need more money than we need to spend for RAM.

e) no need because all you will do is browse or chat or write word/excel/powerpoint documents.

2 Browsers shouldn't take up that much memory. A program that displays text and images should never take up this much memory.

3 People don't use computers only for browsing. There are other purposes like development, modeling, etc for which us students, developers and modelers need all the RAM we can get.
