Firefox problem

[dave22]

Hello, first off, I would like to say I do not know if Sandboxie is in anyway responsible for my problem.
Basically from time to time for no apparent reason, my sandboxed firefox freezes up. It always happens when i have several tabs open. For about 15 seconds I cannot click on a different tab, everything freezes. After about 15 seconds everything reverts to normal. I cannot give any specific website or example when this happens. It has started happening on both my laptop and desktop. I cannot reproduce the problem , it seems random
I have windows 7 64 bit , Firefox 35 , Sandboxie 4.14, although this has been happening for some time so the versions may have been different before.
One last thing I have flash protected mode disabled.
Has anyone else had the same problem. Is there a way to tell if this is Sandboxie related. Many thanks

Hi, migrate to the latest beta available in the first place http://forums.sandboxie.com/phpBB3/view ... 49&t=19837

Afterwards delete contents of your sandbox.

I'm not familiar with Win 7, but on XP I would leave open the Task Manager window on my Desktop, and click on the Processes tab. Then click on the top of the CPU column, so that processes are listed from highest to lowest in percentage of CPU time being used.
As the problem occurs, see which process is listed as taking the most CPU time in that window.
For me, it's usually either my firewall or my AV program.

Hello Dave!

I am experiencing the exact same problem as you do, for about half a year now. I've tried troubleshooting it but to no avail - it really seems random. Event viewer doesn't save any info on the matter.

I, too, have Windows 7 x64, latest Firefox and Sandboxie 4.14. I also use Avast as my antivirus. My suspects are Firefox, Sandboxie, Flash and Avast - the combination of two of them. If you aren't using Avast I can exclude it from the equation.

I, too, have Flash protected mode disabled. The freezes last about 10 seconds or so, could be 20, never really measured the time. The screen freezes up, Firefox and everything else, I'm only able to move the mouse cursor, keyboard freezes as well.

It even happened a couple of times that the mouse froze as well. And usually if I play music in the background (I use Winamp) it keeps playing during the freeze - but a couple of times it silenced the music during the freeze as well.

I would LOVE to come to the bottom of this problem. Maybe we can pull that together, first please tell me if you are using Avast AV too. I hope that someone who has the same freezeing problem will write here too.

PS: The problem has to be Firefox-oriented and those are the add-ons I use in FF: AdBlock Plus, Flash, SumatraPDF. Do you use any of them? I would love to try and surf using a non-sandboxed FF for a couple of days but am not willing to take the risk. Doing it in a VMware environment could maybe show a difference but I don't have the time and resources for that. But, that would certainly show if Sandboxie has anything to do with the problem (I somehow think it does). Anyway, give me as much of information on your system please and let's find the problem and fix it.

Thanks Mr X. I will upgrade to the latest beta, I doubt it will make a difference unless invincea were aware of the problem. I believe I reverted to 3.76 at one point, to no avail. My sandbox is set to auto delete.

Thanks Guest10 ( I know you are extremely knowledgeable about Sandboxie ) I will give that a go

Very interesting that you have the same problem. I too use Adblock, flash and sumatraPDF,. I will remove adblock and the pdf reader see if it makes any difference.
I tried running FF unsandboxed and did not get any problems. Personally I think the flash player may have something to do with it

Many thanks for all the replies

Hi dave22, sounds to me like an issue with something like a web guard, URL filter, something like that. If your AV ha one of those, test disabling it to see if there is a difference. An addon can also cause the issue. But smells like the web guard or AV toolbar or addon messing things up with SBIE

Thanks Bo, I have Avira free, it has no web guard. I have MBAM pro, website blocking turned off. I will turn off all MBAM protection, and have a good think about any other programs. Cheers

Dave, you mentioned removing Adblock plus. I have AP in two computers along NoScript and Downloadhelper, this addons as far as I can tell work great with SBIE. For Adblock plus, I only use the Easy list filters. They don't seem to cause an issue. But if you are using a bunch of filters, that could be it.

Maybe consider using Bluhell Firewall as adblocker for Firefox (much lighter in use but no whitelisting).

https://addons.mozilla.org/en-US/firefo ... l-featured

About this Add-on
All we know the availability of popular AdBlockers lying around... but frankly, these are too bloated with several features and options which most of us don't use beyond the defaults. So, this extension was made for those of us who don't care about all that stuff but does about just getting rid of all the nasty resources being loaded by websites.

This is a lightweight extension (ie, 30KB compared to ~700KB of other popular adblockers), which was made with performance in mind. No configurable options, subscriptions, additional features, etc It just block what can go to hell

How this is achieved is thanks to just seven hard-coded blocking rules covering about 8400 .com and .net domains, these were auto-generated from Easylist. That means, every time a certain resource wants to be loaded we will have to iterate through a list of seven compiled patterns, rather than for each entry from a common Easylist which contains hundreds of different items to check... You can now figure things out for yourself...

Next i'll let you decide if this is for you... as long performance is in your mind, it should.

You can turn the extension on/off at any time by clicking the toolbar button (Fx Desktop), or touching the menu item entry (Fx for Android)

Thanks I may look into that at a later date.
One thing I have just noticed, an add on openh264 video codec. Apparently this came bundled with Firefox 33 about October 2014. This would tie in with the timeline on my problem. So i have disabled that too. Thanks again everyone

[bo.elam]

Dave, you can get rid of that plugin totally. I did. Go to about:config and change preference "media.gmp-gmpopenh264.provider.enabled" to False. The plugin will go away completely from your Plugin window.

You are using Avira without a Web guard and I'm using Avast with a Web shield - I guess we can exclude the AVs out of the equation.

I have the Video codec OpenH264 from Cisco Systems, Inc. DISABLED (via CCleaner) in Firefox. Should I disable it the other way (provided by Bo) to troubleshoot the problem?

I'm experiencing another thing for some time now: sometimes when I start up Firefox (always sandboxed) and start typing a word into the Google search or my name into the Gmail login bar it would "eat" a first couple of letters and restart to blank (it all happens in a few seconds). Anyone else experiencing this?

Thanks for that - I am trialing it now, seems to work as stated. It does't seem to block youtube annotations within the video tho.
In FX you can block them in your UserContent.css file

@-moz-document domain("youtube.com") {
/* Hide annotations */
#player.watch-medium .html5-video-content,
#player.watch-large .html5-video-content,
#alerts,
.html5-video-content .video-annotations,
.annotation {
display: none;
visibility: collapse;
}

Basically from time to time for no apparent reason, my sandboxed firefox freezes up. It always happens when i have several tabs open.

Never get complete freeze ups but sometimes a hesitant long lag. A couple of users indicate a fix for that by adding either
OpenWinClass=# or OpenWinClass=* to their sandbox settings.
