(Firefox :: General, defect)

Description

[oejut]

User-Agent:       Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.9.2.3) Gecko/20100423 Ubuntu/10.04 (lucid) Firefox/3.6.3

When it locks up you have to restart. You lose all of your data, etc. I don't know for sure, but if you explore some websites using tabs, and websites that have a lot of ads, it tends to lock up faster.

Reproducible: Always

Steps to Reproduce:
1.Open Firefox
2.Browse a few websites with some ads, and open some tabs
3.Firefox locks up and you lose everything.
Actual Results:  
It locks up,you need to restart Firefox.

Expected Results:  
Normally, the "Well, this is Embarrassing" page would come up but instead your homepage opens up and you lose everything.

I am using the default theme. Please PM me for more information if you need it. I don't want to open up any more pages as it will crash Firefox.

Hi. Thanks for the reply but I have tried that twice and it didn't work. I get the same problem.

Which Flash plugin do you have installed ?
We need a stacktrace with debug symbols for this hang but we have only instructions for crashes available for ubuntu :

You might want to ask the Ubuntu support what to do in your case.

Sorry I found Firefox 5 appears to have a trojan built in the program. It will begin to lock up other things also same time firefox freezes. It appeared when firefox updated to 5 immediatly. Because during install you  have to give permission on your firewall to access the internet. Once I did that happened I had nothing but trouble and my virus detection did not detect it because I gave it permission to acces the net. It's in firefox. Now I have to try and get all my favorites that won't import back to Iexplorer. Ummm This is a Firefox develping issue that went rogue. I removed everything. Clean system again no problems. Ok I said to myself. Lets see if they fixed it. I re-installed Firefox 5 and there it is again. If I lose system information Firefox has a legal issue. This is rediculous and malicious.

Sorry, Firefox 5 does not have a trojan. Yes, you have to allow Firefox to access the internet, as it is, well, a browser. If you are getting Firefox freezes, then it may be a an issue with your profile, computer, or Firefox, but not a virus. support.mozilla.com can assist you with your issue however.

Mark: This report is for linux and for Firefox 3.6.x, not windows and Firefox5.
Your report is clearly a different thing and you should not comment in this bug.
And please note: This is bugzilla, the developer area and not the support or a feedback forum.

You also seem to be to misunderstood some basic things.
A firewall that restricts the access to networking traffic have nothing to do with an Antivirus software.

>Once I did that happened I had nothing but trouble and my virus detection did not detect it because I gave it permission to acces the net.
Your own (wrong) logic is very easy to counter with:
>I re-installed Firefox 5 and there it is again.
Your Antivirus software should have found a virus during the installation/download if firefox would be a virus/trojan.

And what i don't understand is how do you get this idea that freezes of Firefox or the system (?) is related to a virus/trojan.

The rule is simple: It's a bug in Firefox if Firefox freezes and it's a system or driver bug if the system freezes. Update the graphic card driver from the nvidia/AMD/intel homepage if you get system freezes, that may help.
You gave no technical details like OS, exact problem description, from which version you updated and you have commented in an unrelated bug. Please contact the support under http://support.mozilla.com if updating the driver doesn't help. There is a support Forum and you can ask for help if you add those technical details in your help request.

This bug itself is incomplete because we got no new information since a year.
