Description (last modified by mmadia)

Firefox (Bon Echo) use 100% CPU when load pages that have Macromedia Flash. System performance is very slow. When close tabs that have Flash-embeded pages, the system performance is normal. I installed the Macromedia® Flash™ Player for BeOS ( but no help. Maybe this package is designed for BeOS R5. But there is no source code to fix the compatibility with Firefox (Bon Echo) on Haiku. This was test with Haiku hrev28847 based on VMWare image on Intel Core2 E2160 and Intel G31 Graphic Express.

Flash for BeOS is too old (Flash 4 files playable only, if i remember correctly), and it works only as standalone viewer or Net+ and Opera plugin.

There is no Flash plugin for Firefox on either BeOS or Haiku. That the page loading takes 100% CPU cannot be related to the embedded Flash media, because it will be ignored if there is no plugin. It's not related to Haiku though in any case, it'd be a Firefox issue.

I'm tempted to close this. BeZilla will indeed use all CPU for a while because of its very slow JS interpreter, but we probably can't do much about this.

And we now have Web+ which works much better, in most cases.

When a plugin is loaded the event-processor thread runs the plugin program, so if Flash (and an ancient one at that) does a lot of processing so does Firefox. You can usually see that when plugins load everything stops. They might have changed that recently though.

I don't think there will ever be any work done on BeZilla. It was a nice piece of software at the time, but now it's just outdated.
