[gentoo-user] problems with the web browsers

[gentoo-user] problems with the web browsers

[M Daniel R M]

Hello list,

Sadly, I'm pretty much disappointed with both web browser installed on
my system: konqueror and firefox. 

Konqueror: very stable indeed, but it couldn't be at another way since
it's a key piece of the KDE environment... The problem comes when I want
to fill in forms (you know... web pages for registering, etc.). It stops
many times without giving us an alert message or some kind of
explanation, so you have to deduce that the problem is not from the
website, but the browser instead. 

I don't know whether problems come from java or whatever..., I've
checked my konqueror preferences and I'd bet they are all OK..


firefox: Here the problem is very very annoying, I've run firefox before
with many other Linux flavours and never..., never got to this status of
inability; once you've got about six tabs opened on the same frame
window, firefox gets close to hang, and you become unable to manage it
anymore, unless you have an infinite patience. Doing "top" from a CLI
shows a %CPU _over_ 100%, amazing!. At the end, you'll have to kill the
process from console. 

I don't know, either, why firefox gets to this status; preferences are
as usual, etc. Maybe the problem roots from the flags when compiling,
but I haven't received any message from the system, IIRC... Is there any
flag wrong on my system? 

This is my /etc/conf.d:

~ # more /etc/make.conf
# These settings were set by the catalyst build script that
automatically
# built this stage.
# Please consult /etc/make.conf.example for a more detailed example.

Have you tried running firefox with all your extensions and plugins
disabled? Which version of firefox are you running and what use flags
do you use?

I am not into konqueror these days, so no idea about that.

As for firefox, most problems comes from corrupted profiles,
silly extensions, etc. So, first I would try using a clean
profile, the easiest way to do that is to create a new user
to test with. If the problem goes away then you know that
there's something wrong in your  profile, try disabling
every extension and plugin before doing anything else.

I remember Firefox was biting me with this too at some time.  The 
solution for me was to go to Edit->Preferences, and in the "Security" 
tab uncheck the "Block reported attack sites" and "Block reported web 
forgeries" checkboxes.  The issue was that those features use sqlite to 
update internal databases of thousands of "malware" sites, and updates 
to these lists were bringing my CPU to its knees.

So try that and see if it helps.

Btw, if you're on a Core2 and a recent GCC, you might want to change 
that to "-march=core2" or "-march=native".

javascript support in konqueror sucks.

For everything else it's actually OK. One of these days it will use webkit as 
the backend and then things might improve. Until then, I'm afraid you are SOL.

I have both those boxes checked & rarely have a problem:
try toggling preferences which look CPU-intensive & see what happens.
Occasionally, I do have a problem with a particular WWW page,
when I have to kill Firefox via 'htop', but it's rare (probably JS).
The 3.0 version was running very slowly on my 2003 machine (AMD Athlon),
but 3.5.2 is as fast there as here on my 2007 machine (Core 2 Duo).

I use Gcc 4.3.2-r3 & have CFLAGS="-O2 -march=native -mtune=native -pipe".

Perhaps [O/T] but is webkit a fork of khtml, or was khtml stopped any 
development and webkit took over?

Webkit is a fork of KHTML (and KJS, KDE's JavaScript engine) but I get  
the impression that it has benefited from Apple's legion of paid &  
full time engineers.

The initial development by Apple was done stealthily, and they made  
significant changes (some of which were quite MacOS specific) so it  
was not possible to reintegrate their modifications. KHTML & Webkit  
retain separate codebases, then.

SquirrelFish seems interesting & relevant to this conversation: http://en.wikipedia.org/wiki/WebKit
(also see <http://en.wikipedia.org/wiki/KHTML>)

Yes, after your suggestion ;-) 

I had those extensions, until today: babelfish, boost for facebook,
foxlingo, suggestmeyes. 
They are not on my firefox web browser any more.
Then I tried once again, and the problem continued there, exactly the
same. Well, I didn't want to touch the next, but..
Now I just have two more extensions left, the most used for me: pdf
download, and clickweather. I just disabled them. 
Tried again several tabs and now... it's OK. Everything seems to be
running pretty stably. 


Mozilla Firefox Version: 3.0.11

USE flags I use are pasted here on my first mail, man.

Thank you very much, the problem seems to be located. Now I ask to
myself whether there is anything I could do in order to have enabled
those two extensions, working and without leave stability on firefox, or
maybe this is, at the moment, not possible.

Yes, as I said just before, extensions (but not silly..) were the
problem; not much convincing to me this "solution", but facts were
clear: after removing or disabling them, firefox run smoothly again. 

BTW, sorry but I didn't understood what you meant when saying about
"profile", (I'm not much got into tech issues, sorry :-)

The best you can do is to report the problem to the creator(s) of
the said extension(s). Somewhere around the configuration of the
extension or in the mozilla extensions site you should be able to
find info about them or a contact mail or a link.

Alternatively, you can try to substitute them with any other extension
or program that can do the work.

Originally they both were checked. Then, unchecked and re-cheched again,
it seems that there were no difference here. Disabling add-ons on
firefox seems to have been the "provisional" solution.

Apart from that, I'm not much sure there would be any significant

ASAP, please!

I think konqueror lacks of such abilities, and they are practically
essential nowadays, but apart from that..., other capabilities are fine
IMHO (speed, stability, ...). Ops! In addition, I realize now that
sometimes konqueror renders (shows) some webpages badly (you know,
things placed in the frame where they shouldn't, etc.)
