Thinapped Firefox not able to update itself

Hey guys,

I wanted to thinapp the Nightly version of Firefox which gets daily updates. However, I don't want to apply the update manually by sbmerge or something, but I want the thinapped version of Firefox to download the update and apply it itself.

So far (using TA 4.7.0) Firefox downloads the update but fails to apply it the next time it restarts. It merely tells me, that "there might be another version of FF running" (which definitely don't is). It seems that there is an issue regarding the sandbox. (it doesn't matter which isolation mode you choose - I tried all of them)

So, can you tell me whether it's possible to create a thinapped version of FF that is able to update itself? What changes should be made to the TA package?

thanks a lot

Frank
