Below diagram displays the defect segmentation based on the operating systems. I’ve grouped all the outdated and less used Windows OSes ( Win 95, Win 98, Win NT etc ) as Windows ( others ), Similarly for Mac Os and Linux and Unix Versions. You can see that Windows XP based Firefox browser has a huge number of defects. I’m amazed with the huge number of defect logged for Firefox in Win XP. This actually shows that there is a huge user base for Firefox in Windows XP and software is much less stable compared to other operating systems ( though this is an hypothetical assumption ).

Here is the bugs segmentation based on components of the Firefox. Bookmarks & History, Tabbed browser tops in defects. Developer would be much interested in this chart as it involves a kind-of technical details. Also, I didn’t include the General defects which counts more than 19,000+, because of the charting technicalities. The other bars becomes very smaller if you plot the General defects. It was a small in-sight for me when I saw “Session Restore” is a seperate component, which got a revamp recently in the Firefox 3.5 beta release.

If you are more curious in such things, try digging the Bugzilla database and find more interesting fact and do ping me.

Note: I’ve taken the “Unverified / Unreported ” bugs into consideration for this statistics purpose.

And it will open up all the browser tabs in your previous session, which is very annoying sometimes.

Now the revamp in Firefox 3.5 beta has made an improvement in the Restore session. Now it got smarter and lists down all the websites that you were browsing in your previous session. And you can deselect the website that you dont want to launch in the current session.

This improvement will actually help you to get rid of the site which caused you the crash previously.
