Avast has only supported regular release builds of firefox (for the webrep), not alpha/beta/RC, etc. Don't know if that would also extend to the other avast shields such as the script shied that you mention (or web shield), but I wouldn't have thought so. But I really don't know what has changed in firefox 23.0.

So I don't know if that is the case here.

Strange, I would have though it would be the webrep with non-regular release versions of firefox.

I think I know what happens.. If you disable javascript in the browser there is no activity on the shield of avast.. In Firefox 23 have been removed the option to enable or disable the scripts from the options menu. Although it is assumed that it is enabled by default and can be modified only in about: config.. But while I have not had any problem when navigating with the version 23 can be that something is wrong with avast.. There is a release candidate 2 that is about to leave..we will see

http://forum.avast.com/index.php?topic=98764.0  firefox 11 to firefox 12 Similar thing happened ..............In addition the uninstaller firefox 23 was executed in autosandbox..

... In Firefox 23 have been removed the option to enable or disable the scripts from the options menu...

There is a topic somewhere here in the Forums about that. I can not find it. If this is the issue affecting Script Shield, I am sure Avast! will turn it around and find a fix.

I can't see how this act (not being able to disable javascript) would effect the script shield. I mean if javascript was able to be disabled then technically there wouldn't be any scripts to scan, but that isn't the case.

There was a previous Firefox release (I think it was v17) that was incompatible with the script shield. Hopefully Avast will catch this before the release version of Firefox 23.

I am sorry I could not contribute to this issue with a satisfactory technical background.
But I thought I should bring to attention that since I installed "Firefox 23.0 beta (x)" the "Script Shield" does not pick up any event from internet.
The same thing goes for "Internet Explorer 11 for Win7 (Dev. Prev.)"

When I start "Windows Media Center" the "Scipt Shield" records just 1 event per Start!

Firefox 23 is about to drop in about a couple of days usually on tuesday.  Like I posted before, if any official Avast people have updated scripshield dlls they would like to distribute b/c Avast doesn't want to release a patch, we would welcome it.

Script Shield stuff is updated via "Virus Definitions Updates". Basically, they could just use the virus definitions updates to ship the "patch".

It's good if Script Shield works, but it's not the end of the world if it doesn't at the very moment for this very build of the browser. There are other shields that still keep you covered, like Web Shield, Network Shield and File System Shield. Those work regardless of the browser version and they also check scripts.

I do not think that that is correct .. because then we might remove this shield .. I think that every shield fulfills his function ... ???

Just updated to the release version of FF 23 and can confirm script shield no longer working.

Interestingly the system hang problem which some users (me included) experience with some websites appears to be fixed in FF 23. That was my first observation, my second was could it be that it was the Avast script shield that was causing the problem?

I personally wasn't/haven't been experiencing any hang time in FF.
Website hangs can be caused by many different things as I'm sure you are aware; limited RAM being one of the main culprits.
Can't say for sure about Script Shield. :)

Script Shield doesn't seem to be working in Opera and in Mozillas's SeaMonkey. Details here:
http://forum.avast.com/index.php?topic=131605.0

@RejZoR, if the other shields do the job, as you menioned in Reply#15, shouldn't we just uninstall Script Shield?
Or what does Script Shield do special when it works?
Title: Re: firefox 23 and shield of script
Post by: RejZoR on August 06, 2013, 10:45:11 PM
Script Shield does additional analysis of scripts on runtime, but in general Web Shield checks the .js files before they enter browser and Network Shield checks their URL. And File System Shield also checks the files.

Post by: cooby on August 06, 2013, 10:54:11 PM
So if I use my own .VBS script, or someone gives me one, will ScriptShield check it as well in addition to files shield and behavior? Or if some .pdf file has scripts in it will the other shields check it?

I believe that in a case as this ,one the team of avast should do a bulletin and explain when approximately the patch will be available ;D
