User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.5) Gecko/20050221 Firefox/1.0 (Ubuntu) (Ubuntu package 1.0+dfsg.1-6ubuntu1) Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.5) Gecko/20050221 Firefox/1.0 (Ubuntu) (Ubuntu package 1.0+dfsg.1-6ubuntu1) Javascript alert boxes are modal, i.e. they totally block access to the window that launched them. This allows a malicious web page to take control of your browser and may force you to kill Firefox, thus losing all your tabs and current session. To see why this is a serious problem, visit http://www.funnyjunk.com/pages/awesome.htm for an example. Your window will work again only after closing 200+ alerts. There is a workaround if you happen to have another previously open window - then you cand disable javascript from the other window. Otherwise, Firefox virtually hangs. A possible solution would be using the new yellow 'notification bar' for all javascript alerts. This would solve all annoyances related to alertbox blocking the user workflow. Reproducible: Always Steps to Reproduce: 1. Open a page that shows a javascript alert, like http://www.funnyjunk.com/pages/awesome.htm 2. Try to use the browser without closing the alert first. Actual Results: It's impossible to use the window in which the alert appeared until you close all the alerts. Expected Results: Alert boxes should include a button labelled "Don't show me more alerts from this page" that disabled javascript in the current tab. Also the menus and other tabs should be usable with the mouse instead of blocked.

I agree. In Bug 286095 "Alert window: "https is not a registered protocol", freezes browser window.", I suggest that there there are many ways that malicious sites can do this. Firefox should hobble all of them!
Sorry, I'm playing with the Steps to Reproduce and I've found that the browser is not totally frozen, it's still accesible from keyboard. But it still is a major problem for heavy mouse users like me (I didn't discovered this until reporting the bug). So I'm downgrading the severity from Critical to Major.
Severity: critical → major
Summary: Alert box blocks access to menus (a.k.a. Alertboxes are EVIL) → Alert box blocks access to menus
