Hi,
i'm developing a WebBrowser plugin for a media application. The browser runs now fine in the application, but it has some performance problems (gui slowdowns etc.) This happens especially if there a some big flash ads or javascript effects.
My first idea was to run the webbrowser in a sperate thread, but how do i run the browser in a thread? I know how to run a specific method in a thread, but how to run the COMPLETE geckoFx browser in a thread?
The second idea was do block the flash ads and the image ads, like the AdBlock extension for Firefox does, but in a simple way. Of course i can check the whole website after the DocumentCompleted event is fired, for unwanted links, but that is not the way a adblocker should work. It should block the ads right when they try to load.
Hopefully someone has some ideas :D

You can't run geckos in different threads from your code. It does it itself internally.
The most you can do is invoke them from threads and wait their responses.
For the adblocker, I think you should subscribe to an event that will fire for each downloaded object in the page, not sure which event you have to capture. If so you could filter the ones you don't want gecko to download. This is how it works with the internet explorer control in .NET, this one should be similar.

Thanks for your reply, Cristian.
I've called the constructor of gecko in a thread and call the Navigate method in a thread. Don't know if it's delusion or it's really faster than before.Whatever..
For the adblocking thing i've edited the "Navigation" event. Now it will be fired with every transmitted data.
Let's say the Navigation event gets fired when the image "http://www.google.de/intl/de_de/images/logo.gif" is transfered and i wan't to block this image. Now it would be good to have a GeckoElement of the html element with this particular url. Then i could easy set the html "style" attribute to "display: none;" for this element and the image is not displayed anymore.
Has someone an idea? I've tried various things with parsing the InnerHtml of the Document, but this was too slow, even for a normal windows application.
