dwb - a webkit web browser

shuuichi_nitori · 2012-12-30 03:49:38

Hi, dwb is wonderful, I'm using it on my awesomeWM right now, but I have a little question.
sometimes dwb gets very slow when I have more than 4-5 tabs open, gets slow when I load big images (>2600px), and a quite slow viewing videos on youtube. someone knows what is happening?

I tested two later Webkitgtk and it turns out that it does not necessarily have to be a bug in the dwb adblock.

The same versions glib2, libsoup, dwb, gcc, binutils.

WebKitGTK+ r138591 (2012-12-31) works fine

Hey, using DWB right now. Oh my god, I like having letters instead of numbers for hint following. It makes me actually use it instead of just using my mouse in vimperator/pentadactyl.

Could you please create a webkitgtk2/3-svn AUR package or something like this? I'm unable to build it myself (fails every time with different errors).

You do realize that 1.11.2 isn't a stable release of webkit?

Have you tried to build it with -j1? Webkit fails to build in most cases when build with more than one job.

grapeli23 · 2013-01-04 00:40:36

Mystery solved. Today I updated libjpeg.
Finally I can open links to graphics in jpeg format. Wow.
It works with all versions of webkit

EDIT:
Mistake. Old config 'adblocker=false'

I was trying to find information about aes-ni, which lead me to the intel site. It seems to freeze dwb completely. I first tried with the dwb from the repos, then with the dwb-hg from the AUR. Also, I tried with adbock_subscription on and off (its the only extension I have enabled).

Can anyone else reproduce this? This is the page I was trying to go to:
http://www.intel.com/content/www/us/en/ … ology.html

I can confirn that too.

portix · 2013-01-10 10:04:26

I can also reproduce it but i can also reproduce in in every other webkitgtk browser.

WonderWoofy · 2013-01-10 15:07:02

Okay, thanks portix... I used to have a bunch of webkitgtk browsers on my machine, but have since removed all but dwb. 'Twas just curious, and wanted to make sure you were aware of it.

It's fine here, javascript disabled (enabled doesn't do any harm) and external domains blocked.

I have the same problem. Here's console output right before freeze:

Just wondering, is the youtube flash to mplayer replacer script in archwiki supposed to be working?

xtremyst · 2013-01-27 14:50:08

hi there, i'm using dwb the last few days and it look awesome, well done mate!!
one question though, i'm using formfiller, when i run efg i manage to save the data i need
but everytime i run eff i get "no formdata found" message, what am i missing?
let me know what other info you might need

portix · 2013-01-27 15:24:28

@xtremyst: Are you using gpg-encrypted files or have you switched from a gpg-encrypted file to a non-encrypted file?
@gothmod123: It works here but on irc someone mentioned that it does not work with some locales.

xtremyst · 2013-01-27 15:53:03

Edit: My bad, i didnt understand your question right... i deleted the content of the /data/forms file, re-enabled gpg-encryption and saved e new form, still getting the same error message..
as you can understand, i dont have any previous gpg experience
my formfiller.js

#!javascript
extensions.load("formfiller", {
   formData  : "~/.config/data/forms",
   scGetForm : "efg",
   scFillForm : "eff",
   useGPG    : false
});

thanks for the reply.

nothing happens for me with the mplayer script. same old click to flash frame appears. I'm using the default US locale.

So I'm just using

#!/bin/bash
# dwb:Mod4 u

mplayer $(youtube-viewer $DWB_URI)

This works but it would be cool if the replacement script worked for me.

First of all... amazing web browser and I love using it everyday.

Also, for some reason when visit specific web pages... such as twitter... an upper case letter will show and the rest of the word will be completely hidden. When I log out of Twitter, I will just see a "Y" and the rest of the word is gone. Has anyone else had this problem?

That seems to be ok, i have no idea and cannot reproduce it.

xtremyst · 2013-01-28 09:40:06

is it possible that the problem is in the /usr/share/dwb/extensions/formfiller config file?
Anyway thanks a lot for your replies, i'll try to see if there's anything else i'm missing asnd i hope i'll figure it out.

portix · 2013-01-28 09:41:47

That's not a config file, that is the extension. Are you using dwb from the repos or dwb-hg from AUR?

Since this is webkit-related, you can still try a newer version of webkitgtk, for example by compiling webkitgtk2-svn from AUR.

xtremyst · 2013-01-28 12:46:19

i installed from the community repo... i edited the extension file at some point (the default config right above the /*INFO*/ part), here's what i got now

PS: in formfiller.js the "useGPG" is now st to true... still cant autofill a form

You shouldn't really edit this file, if you want to edit it you should copy it to ~/.local/share/dwb/extensions/, but the default options are ignored if you set them in your script anyway. My suggestion is, reinstall dwb, delete the file that loads the extension and then enable the extension with

dwbem -i formfiller

Arch Linux
