BTW: Sometimes desktop links opens the bookmarks window,
sometimes not. Strange.

So, how to disable the appearance of the bookmarks
window when opening desktop links?

My N900's problem is that the bookmarks window
jams the browsing badly. Even if I immediately
close the bookmarks window, the browsing is
jammed. When bookmarks window does not
come up, browsing works ok.

More strange happens: it takes 9 minutes to open
a webpage via the bookmarks window. Thus
I prefer the desktop links.

But then the desktop links may cause more problems:

Only four desktops, so many links. No ability to
organize the links: say, by labeling and grouping
desktop areas.

Perhaps because I have so many links, the system
menus are starting to show as black: menu entries
are invisible. Likewise the character dialog.
The desktop links and app icons are many times
invisible too. The toolbar bitmap is showing
wrong bitmaps: like the clock is replaced by
bitmap taken from some other part of display.

Switching to other browsers is no because
Firefox Mobile and Opera are some kind of jokes
compared to the Web in usability.
(And I have advice: when hardware is limited,
the browser should be more cabable, not
reduced like Firefox Mobile.)

Strange. But then, I don't know much about them, I don't use them.
Theoretically, startup page could be disabled, or, at least, changed, in "about:config". However, it seems to be useless: I have not seen any sign of this setting being used by the browser.
Did you know how many packages are connected to default browser, in one way or another? microb-eal, microb-engine, microb-engine-common, tablet-browser-ui, tablet-bookmark-manager, and many others. Searching for bookmark window is a nightmare.
So, we need to find the bookmark-list-window and figure out how to make it work faster.
For me, MicroB is broken. I don't know why, but I cannot even open GMail in it. Most of the time, "not redirecting properly"...
So, you need to make your own simple HTML page with all your bookmarks, and then start MicroB with this page and without list of bookmarks.
Oh, and I thank Sentinel1705 for tip: there is a small config file at "/home/user/.browser".
And there are MicroB tweaks.
And who knew that MicroB renders not only nokia maps, but also chat conversation and SMS conversation, if rtcom-messaging-ui is to be believed?
If you want a desktop-like browser, look for chromium on Maemo 5; I still have it installed, though I mostly use Fennec 16 (17 could not install correctly, for some reason; 18 will be ported shortly, and promises speed improvements).
Since you prefer to use MicroB as default, this should work for you:
Just create a shortcut which would execute the code, and put URL to you hand-made list of favourites into the code; then the shortcut will start MicroB without bookmark window and with list of links to your favourite pages.
Best wishes.

The final tested working solution for this issue is the following script which will open the url from parameter 1 with a single maemo browser window:


#!/bin/sh

current=$(browser-switchboard-config -b)
browser-switchboard-config -s -b "microb"
dbus-send --system --type=method_call --dest="com.nokia.osso_browser" --print-reply /com/nokia/osso_browser/request com.nokia.osso_browser.load_url string:"$1"
sleep 5
browser-switchboard-config -s -b "$current"
