723736 - Pressing enter too fast causes crash with Firebug

Status: RESOLVED WONTFIX

(Core :: JavaScript Engine, defect)

Description

[Jakob Heiss]

User Agent: Mozilla/5.0 (Windows NT 6.0; rv:10.0) Gecko/20100101 Firefox/10.0
Build ID: 20120129021758

Steps to reproduce:

I visited the web-site:

http://profizocker.aktiv-forum.com/h14-siedler-kampfsimulator/

(I have created this web-site)

I fillied in the formula, with something like this:
profizocker.aktiv-forum.com/h14-siedler-kampfsimulator?R=200&PL=12&M=0&SL=12&S=0&WH=12&C=0&RB=12&B=0&SW=12&LB=0&WL=12&Boss=Stinker

Then I clicked the blue Button "Angreifen!"

Then I pressed the enter-key and kept it pressed a few seconds. (You can get the same resut, wehn you press the enter-key extremely fast very often)

I tried to slow the web-site down in a new version: http://profizocker.aktiv-forum.com/h22-kampfsim-beta-2
But this didn't help very much.

I have tried to reduce the web-site to the problematic parts, to be able to locate the bug more precisely:
http://profizocker.aktiv-forum.com/h23-test-submit
This testing-site is much more stable, but it can crash too, if I press the Enter-key for more than ~10 seconds.


Actual results:

Firefox 9.1:
After I stopped pressing the Enter-Key all buttons on the website were dead. I was not able to close the tab or to navigate to another tab.

I was able to close Firefox, but when I wanted to restart Firefox, Firefox didn't want to start, because the process wasn't finished. After I restarted my PC I was able to start FF and Session-Manager asked me to restore the sesseion. Then everything works fine.

Firefox 10: crash-report


Expected results:

Oeera, Chrome and  IE react the way, it should be.

When I keep pressing the Enter-Key the output formular changes very fast and everything works fine.

DO you get a freeze/hang or a crash ?
Please provide a crash ID if you really get a crash.
- https://developer.mozilla.org/en/How_to_get_a_stacktrace_for_a_bug_report

I can't reproduce a crash nor a hang with Mozilla/5.0 (Windows NT 6.1; rv:12.0a1) Gecko/20120129 Firefox/12.0a1 SeaMonkey/2.9a1 and FF10

Please try it again in the Firefox safemode

In Firefox 9.1 it always freezes/hangs (=> In Firefox 9.1, it never crashes)
I was only able to close FF. It looks like FF closes correctly, but when I wanted to restart it, it did'nt restart, but asked me to restart my PC or quit the process (after restarting my pc everything works fine)
It also happens in Safe-Mode

Firefox 10 crashes. And FF 10 shows me a crash report and I can restart FF very quickly (without restarting my PC)
But yesterday I mangaed to get the freeze/hang with FF 10.
I will try it in Safe-Mode too.

PS: Clicking very fast on the submit-button (called "Angreifen!") has the same effect, as pressing enter very fast.

Today I canNOT crash or freeze FF 10 in Safe-Mode.

Here are the crash IDs:
bp-1201ad47-0da9-4c90-bc38-20d852120202
bp-719c685b-3576-4446-bcba-020a32120202
bp-1214f6af-3749-4fc7-a763-23a032120202
Two are new crash signatures, one is bug 674854 caused by Firebug.

It means that it's caused by one of your add-ons. Can you tell which one is?

Comment 5

[Boris Zbarsky [:bzbarsky]]

The jsdValue signatures are also a JS debugger; presumably Firebug.

Comment 6

[Jakob Heiss]

I think "Lazarus: Form Recovery" causes the problems. But, when I remember right the bug happened also once or twice without Lazarus.

But, at the moment my FF 10 stopped crashing and starts freezing/hanging (like FF9).


PS: Everytime, when everything works fine: The output-field change ~10-100 times per second, while enter is pressed.
Everytime, before FF crashes or freezes/hangs: The output-fields change only once (while enter is pressed)

It's a low volume crash with only 25 crashes in 10.0 over the last four weeks.
It first appeared in 10.0a2/20111208.
All crashes occur with Firebug.

Comment 8

[Jakob Heiss]

The crashes only happen with Firebug.

But sometimes it hangs/freezes, when Firebug is DEACTIVATED and Lazarus is activated.

Today I tested it with FF 10.0.1:
Lazarus on;  Firebug off : hang-freeze [1/2](=in one out of two tests)
Lazarus off; Firebug on  : crash [4/4]
Lazarus on;  Firebug on  : crash [3/4]
Lazarus off; Firebug off : everything works fine [1/1]

That's another issue. File a new bug for that.

Closing because no crash reported since 12 weeks.
