Firefox becoming more unstable…
By
Now I know I’m not the first person to complain about this, I just did a quick Google search and it appears this problem is common. I have noticed that my very good and stable browser Firefox, running on Windows XP, has become less stable as new releases come out. What surprises me is that these new updates that I keep getting asked to install are minor versions – versions supposed to fix existing bugs, not introduce new changes/features with new bugs!
My current version 2.0.0.11 of Firefox appears to be the most unstable, regularly crashing on AJAX applications such as Facebook, Yahoo Mail, Pandora and Startforce. Even my own site, as I’m using TinyMCE, a javascript editor, seems to have problems when I use it sometimes! What surprises me is that IE6, which is much older and I used to complain about, seems to actually be more stable!
Now the obvious reason is that developers build and test for IE6 as it is the most common browser out there, but I thought Firefox’s strength was that it was open source, standard compliant, and had a large community of developers fixing bugs quickly as they came up, not introducing new ones!
These issues are going to slow down Firefox’s success! Many of the great features it has like multi-tab browsing, have also been copied by Microsoft in IE7. Firefox should keep the browser slim, fast and most importantly stable if they’re going to continue to grow so fast. With so many AJAX applications appearing the development should focus around it JavaScript engine and making it stable and secure.
Anyway, that’s my piece for today, leave a comment if you’re also having problems with Firefox!

Ive used firefox 2.x.x for quite a long time and found it to be quite stable. I am runing it on linux, but thats besides the point, all of my firefox converts are windows users and they are quite satisfied. On my PC at any given point there are atleast 30+ tabs open, i use all of these regularly, flickr, digg, facebook, twitter, many web 2.0 apps, even use TinyMCE on Joomla no problems at all, even in the rare occasion that firefox crashes it restores the workspace.
I’ve met some people who say the same thing as you, and others that agree with me, I can only base it on my own experiance, but I’ve heard a lot of rumours about memory leaks in Firefox, which is causing the crashes and they are hopefully looking into it for version 3.0 release.
