ReHIPS / Various questions about Rehips
« Last post by Cuslichavy on November 09, 2019, 02:49:20 am »
Hello, I've been using Rehips for a few days and I'd like to learn more about its features and limitations. I've a few questions.

1. Does Rehips compromise Chrome's or any other web browser's own sandboxing? I know Sandboxie does.
2. I run my browser non isolated. Can I open links from an isolated program to my non isolated browser?
3. Every time a program updates I have to give permissions again. I'm running Rehips in expert mode. This is even worse with Chrome because every update uses a different folder. How can I make a rule to let software auto update without Rehips notifying me each time? At least for Chrome. Rules is where I struggle the most right now. I also deleted the default rules for Chrome and Firefox in the default rules database but I made a backup first.
4. Folders in C:\ReHIPS. How do I make other folders beside Default and Browser. I made a new folder and gave rwx permissions to a environment, but didn't work, the program in that folder won't even run isolated. Do I have to change permissions of the actual folder (from Windows Explorer) authorizing a Rehips user to make it work or is there a better way to do this?

Thank you in advance.

PID is a Process ID. You can read more about it here https://en.wikipedia.org/wiki/Process_identifier In short words, it's a unique number assigned when a new process is started until it exits. So for example when you have multiple svchost.exe - s, by PID you can identify which one of them you need.

ReHIPS / What does PID mean as shown in the ReHIPS Log?
« Last post by Stephen on November 05, 2019, 08:53:02 am »
When I look at the ReHIPS log I see "PID" with a number shown in each entry. I assume that PID means Program ID, but what does the number mean?

ReHIPS / Re: Firefox as a default browser

When you install rules from the Programs tab, RulesManager comes into play. Here is a blogpost about rules installation https://forum.rehips.com/index.php?topic=9529.0

In short words, if some rule is already present in ReHIPS database, it won't be overwritten, only missing rules will be installed. So if you deleted Firefox rules, they'll be reinstalled. If you modified some other rules, they're present and won't be reinstalled. But if you deleted some other rules, they'll be installed back, that's why here https://forum.rehips.com/index.php?topic=11838.0 I recommend not to delete rules, but to change them instead.

Thank you very much for the explanation. The better a user understands how some settings work the less risk there is that he or she will not make a mistake.

Based on your explanation, I would like to ask if I remove Firefox's IE and reinstall the default rules would only those rules for Firefox be reinstalled or would reinstalling the default rules (by clicking on the relevant button) also reinstall rules for any other programs that are not working an an IE, but for which I may have changed some settings?

You're right, all settings are copied into isolated environment. And it looks like there are 2 separate Firefox instances: one non-isolated and one isolated, each with its own set of settings.

Why was it done this way? For security purposes. The real settings aren't synced with isolated environment so you could use non-isolated firefox for example for banking and isolated instance has no access to banking settings in case you could have saved something sensitive (though you can resync it by removing isolated environment and reinstalling default rules). And isolated settings aren't synced with real environment as they're treated as compromised and who knows what they contain.

I disabled checking if Firefox is my default browser. It seems to work, that is I'm not being asked if I want to set it as my default browser.

As regards the background color of the Options pages, I have the same version of Firefox as you, but in my case if I start Firefox with ReHIPS disabled, the Options etc. pages are dark. If I enable ReHIPS and start Firefox, then the Options etc. pages are white. I have unchecked Copy User Data.

I don't know if it's relevant, I installed an add-on to Firefox while ReHIPS was disabled. When I started Firefox with ReHIPS enabled, the add-on was missing. I installed it again.

It's as if there are two separate installations of Firefox (at least as far as the settings are concerned), one with ReHIPS disabled and another with ReHIPS enabled.

I remember you're using Windows 10. From Windows 10 programs are not allowed to explicitly set themselves as default file handlers. So Firefox can't explicitly tell: now I handle http, use only me. Instead it shows a Settings->Default apps window and humbly waits for the user to set it as default. This requires interaction with shell and isolated Firefox can't do it. And to be honest, you don't need it. Only file associations for your real user matter, they define which browser will be opened for http. So the best way in this case is to simply disable this check for isolated firefox.

Background color is probably related to Set Hooks being disallowed (which is the case in firefox default rules). I have firefox 70.0.1 and I see white background in both isolated and non-isolated firefoxes. Does it pose any difficulty?
