Thank you

So this looks like it happens during a rev-upgrade for some reason. Can you tell me (or show me) what happenned just before this, to trigger that rev-upgrade event?

Usually something would have been installed, then some inconsistency found (like a stdlib mismatch for example) to trigger the rebuild.

I tried to install Waterfox Browser 52 on Snow Leopard, which complained of missing libc++.1. library, and crashes

Dyld Error Message:

Symbol not found: _strndup Referenced from: /Applications/Waterfox.app/Contents/MacOS/libmozglue.dylib Expected in: /usr/lib/libSystem.B.dylib

in /Applications/Waterfox.app/Contents/MacOS/libmozglue.dylib

so i tried with Macports to overcome,

and probably during the process i tried also to install Homebrew (which failed miserably due to curl-issue) and installed Git manually , maybe this could have evoked an error?

Ah. Well, cleaning all this up might be a project.

In your case, you would have been OK to just

sudo port -v install libcxx

and it would have installed /usr/lib/libc++.dylib for you and solved the missing library issue. However, I doubt the browser would have worked anyway as it sounds like it's built against 10.7.

For right now today, the best browser for 10.6 is (IMHO) Firefox 45.9.0 ESR, which you can get right here in many languages <​https://ftp.mozilla.org/pub/firefox/releases/45.9.0esr/mac/>.

That is the last Firefox available for 10.6.8, and works pretty well, although it is not up to date with security features.

Several of us are working to bring TenFourFox to older Intel systems. We have it building and running now, and it is fully up to date with security fixes. It is not quite ready for general use just now.

Thank you Kencu,

if i remember correctly i tried that already before but that did not completely solve the issue so i thought it might be worth a try to test the long road.

i do use firefox 45 esr on my system , but it is sometimes a bit outdated (example: twitter). on lion 10.7 i can use waterfox 56.2 , which is otherwise also limited to firefox 45 esr.

it seems on 10.6.8 i am stuck then for now with firefox and waterfox 48 (which opens correctly). actually, safari is best on 10.6.8 in terms of speed, but fails quite often to open pages due to security isseus i think.

I use Tenfourfox 17 (with plugins) and Tenfourfox latest quite regularly . it would be great if it be possible to make it also available in a docker-like format, so that when one has 2 versions of tenfourfox installed , say 17 and a newer, the can run independently, otherwise it is a bit complicated with the plugins and add-ons which tend to update themselves or get deactivated.
