In that video in a thread, they're running Fennec with an extension called "weave". It connects your mobile with your computer, and vice versa. Tabs open, extensions..etc.

It looks really interesting!

So is there any chance of getting Weave addon to work with Maemo Browser ?

That would be pretty awesome. Fennec isn't looking all too hot yet, what with the lag and all...

Ehehehe… Take it easy…

The video of the guy from Firefox demoing it on the N900 uses it and explains it pretty extensively. And when he looks at the extensions, the top of the screen says "Fennec"
So yeah, it does work with tne native browser

No. That doesn't work.

My experience of Firefox on a laptop (all versions; I'm using 3.5.4 now on Ubuntu 9.10), is that open pages sometimes consume a lot of power.

Many pages are static and should consume no power at all when not actively being used. But a disturbingly large number of pages have enough Javascript and/or flash and/or animations running that if I ever see my CPU using 50% or more and I'm not doing anything, it's nearly always Firefox using it on another desktop.

There's not a lot it could do about that, unless you want it to freeze script activity in windows that haven't been used for a whlie and/or are not currently visible.

Anyway, for that reason, I sometimes find myself quitting Firefox as a whole when I need to conserve battery on my laptop, and restarting it when I need to browse some more. The "restore all tabs and windows" feature is invaluable for that.

It doesn't help that you can't tell which pages are causing the CPU consumption, except closing them one by one, so that makes it hard to be selective.

And that's why "just keep all your windows open" won't work - unless they have found a magical way to stop excessive CPU consumption of all web pages.

Of course, I don't really need these 50 tabs open all the time. It'd be fine to have something more like "currently in use" bookmarks that behave _similar_ to open tabs & windows in keeping a large rendering of the page to hand, as the position in the page I was looking it, so I can flick through them to remind myself what of active items I'm researching, but with scripting activity inactive. (Bookmark titles don't work - titles are often useless as reminders of just _why_ I put some page aside while working on something else). I haven't found a bookmarking plugin thats suitable for me, for Firefox yet, but hold out hope still. Maybe it's built into N900 already? ;-)

I believe the question was in regards to the Maemo browser (often called MicroB, though that is inaccurate). Fennec is a separate browser, one not installed by default.

By default, the Maemo browser does pause JavaScript.

For Firefox Desktop, you need to check out the Too Many Tabs add-on. It creates another toolbar for parking tabs. Want to temporarily unload a tab from memory? Click on the little arrow & it bounces to the TMT toolbar. Want to load it again for viewing? Click on it again and it bounces to the regular toolbar. It appears to be compatible Tree Style Tab, another tabaholic add-on for viewing open tabs (i.e., taking up memory) in a tree control.

I'm not sure this would work with the N900, but you might want to check out this tip on integrating Google Bookmarks with your browser (in this case it's Tear but hopefully other browsers work similarly).
