im using the Tree Style tab extension to make the tabs going vertical on the left side, using a 1680×1050 resolution

That’s one hell of a widescreen monitor you must have Jimi!

Wow, I and I thought I had a lot going when there were 8 tabs up…

i have been using FF3 from betas to the new RC2 and its nice but it still got some problems i also had with FF2, im the type of person that browse alot of webpages and forget to close the tabs, often running 90-100 tabs and to me FF3 use the same amount of memory as FF2 did around 500mb-1gb depending on how many days it have been open, but in general a great browser

Don’t know what to tell you in terms of extensions… I did this on my Mac with RC2 to create the instructions and it works fine for me. Regardless… any time an application is updated, there are legacy issues to deal with. Firefox is no exception and this isn’t necessarily the final version. This is also part of the reason I’ve stuck with native apps… no legacy issues to deal with. It’s a trade-off for functionality in some cases, but I can live with that.

I’ve been using FF3 right through the betas up to RC1 and just installed RC2 on my M700. All has been well apart from some pretty constant crashing on Vista 64 on my desktop. Firefox would just bug out and have to be restarted a few times a day. I think a few people have had stability issues.

Hopefully RC2 may resolve. I do like FF 3, it’s fast, I love the plugins like the essential Adblock/Flashblock (turned off for JKOTR!), and the wonderful grab and drag.

I did this and before I could install any extension ran into trouble. Restarting Firefox after adding the config setting rendered Firefox unable to run and I had to go back to FF2. This was on the Mac. This incompatibility is why I haven’t tried FF3 yet and I’m going to wait until all my extensions are supported.

How about Evernote clipper? Any way to get that on FF3?

In the address bar, type “about:config” (without quotes)

Right click anywhere in the browser and click New, Boolean.

Enter this name for your preference: “extensions.checkCompatibility”, again without quotes.
At the next prompt choose False.
Restart Firefox.

I just did this and was able to install Google Browser Sync. Didn’t test the functionality, so let me know if it doesn’t work… there might be another preference to add or edit.

no, how do you do that exactly? google toolbar is not compatible either.

Incompatible extensions are likely to be an issue for a few months. Did you go into about:config and turn off the check for extension compatibility? Good chance that it will work then.

Just installed it on the Mac and it is definitely nice but one killer for me- Google Browser Sync is not compatible and can’t be installed. I’ll have to go back to FF2 for now.
