How do I over-ride Firefox 4's refusal to allow installation of Torbutton v1.3.2-alpha?
The developer at the Tor Project has been testing Torbutton v1.3.2-alpha (unstable). Although not fully stable, it's being released for users to test. Informations is at https://blog.torproject.org/category/tags/firefox and https://www.torproject.org/torbutton/ . When I tried to install this alpha release from the 2nd link's page (look for "Install alhpa" on the page), Firefox 4 refused to allow completion of the installation. What I need to know, is how do I over-ride that refusal, to achieve installation?

I haven't tried to install that extension specifically, but I'm going to guess that Firefox thinks that it's only compatible with 3.6.x versions of the browser. There are two workarounds - one is to modify the extension itself to report that it is compatible with 4.x (which you could do yourself, or you could ask the developers to update) , the other is to disable compatibility checking altogether, like [this.]
That torbutton-current-alpha.xpi file has a maxVersion of 4.0 instead of 4.0.* as would be required to make it install in Firefox 4.0.1
<em:minVersion>3.0</em:minVersion> <em:maxVersion>4.0</em:maxVersion>

Thanks for the replies. Yes, they were both helpful and informative. However, the bottom line is that in order to work around the compatibility problem, I'd need to do some re-programming of Firefox, with subsequent risk of "malfunctions or crashes". It's simpler and safer, to just abandon use of the version 4 as being fundamentally defective, uninstall it, and return to use of v3.6.3 which worked correctly most of the time. I appreciate your assistance!
