Hi again!!
I'm surfing with FF3beta5 (portable, of course), but it would be great to do it in spanish. I haven't found any language pack in Mozilla site. And the switcher doesn´t works in ff3.
Any ideas, please?
Thanks in advance!!! Papps keeps rockin'!!!
Use the advanced way:
Thats it.
Thank you very much, ptmb!!! Everything clear!
But I have seen that there are problems if I keep FF2 installed, and I'm going to erase 3beta. 
Thanks anyway!!!
Problems? I have Minefield 3.0pre (even unstabler) installed in some sort of portable way (no install) and I have no problems.
You can't run the two at the same time (without some tweaks), but you can run the two on the same PC w/o a problem.
Also, I didn't say to install, just to be clear, I said to extract the contents of the installer. Just to be clear.
Even like that, no problemo, always on orders.
+ Trick for the ones who don't want to use installer:
EDIT: I remembered that if you install Firefox 3b5 together with 2 it will corrupt your profile, but there's no problem with the Portable version as it uses a different profile folder, if you'd like to know. If the problem is that, no problem.
I will try your fix, I think. Thank you very much again
My problem was: when I open ff2 after install ff3beta (closing ff3 before), it opens an installer. I don't know much of "tuning" apps, as you can see, and it has "frighten" me a little...
You installed FF3beta5 right, not the portable version. If it was that then it was the check for compatibility of addons that happens when you run a different version of Firefox. That only checks if the addons installed while on 3beta (if any) are compatible with 2.
I hope to have helped and you're not obligated to do nothing (I take that from your "Glups"
) It is good to have things documented to help people with similar questions.
