I am reluctant to bring this up, since I realize that 1.5 isn't officially supported yet by Breezy, but, like many people I am sure, I've installed 1.5 (now at 1.5.0.1). I put it in /opt, as suggested on the Ubuntu wiki. In any case, 1.5 frequently crashes, more often then not in the background; it will spontaneously just close, or it will freeze up and I have to kill it.

I thought perhaps it was an unruly extension. So I systematically disabled all the extensions I had installed. Nope. I thought maybe it was Gmail. Don't think so either. Tried launching firefox from terminal to see if there are any useful error message, but nothing there either. What could be maikng it so unstable?... Anyone else seeing this?

If I don't get to the bottom of this now, I am hoping that the forthcoming Dapper will solve this problem.

Yeah it crashes for me too. I think it's a conflict with java. I can click on some links with it and it just closes. If I go to the same site using another browser it ususally has java in the startup page. Firefox guys probably know about it and will fix it sooner or later.

I just was at the wiki and came across this:

If you use an Intel 855GM video card, ensure you set the X server colour depth to 24 bits, otherwise you will probably experience Firefox crashes.

You may need to install the gsfonts-x11 package for flash to properly display fonts.

Java??? Well, perhaps... but I kinda doubt it. First, 1.# didn't have these problems. Nor, in my experience, does 1.5 under Fedora. Plus, how many sites actually use Java? I don't have stats, but in my experience not that many. Now, if you said, Javascript (not the same thing as Java), I'd find that more plausible, even though, as I said, I don't see this happening under Fedora.

I think it may be Ubuntu/Kubuntu. I was experiencing the same problem with 1.07 and upgraded to 1.5. If anything it made the situation worse. I don't recall ever having the problem when running Slackware.

Obviously I'm in the minority here, but I've never had this problem--either with 1.0.7 or with 1.5.

That said, it's possibly a corrupt profile. Try this, and see if it makes a difference.

Tried that, didn't help any. Thanks for the help though.

Has ayone found a solution to this problem? It's really annoying. I'm tempted to switch back to Slackware.

My firefox crashes often as well. Another annoying problem is, that some sites block the whole browser. For example ebay, while loading the page, I can not use firefox on the other pages (tabs I mean). It is so annoying that I sometimes use Opera, but that has it's shortcomings as well.

NOT a generic Ubuntu issue. I have Firefox 1.5.0.1 on Ubuntu 5.10. There are some Firefox funnies, but crashing is not one of them.

The issue may not be Ubuntu/Kubuntu, but I also never experienced this problem when running Slackware and I have used Firefox since the time it was still considered Beta. Perhaps it is something installed seperately from a standard install (universe) but it still is annoying as hell and seems to be nearly impossible to track down.....

I'm getting the same problem on suse and slackware
