Fix: Scripts Failing in Firefox 89

Issue 1: Firefox 89 has enhanced the privacy of its Private Browsing mode. By default, Firefox now blocks cross-site cookie tracking in private browsing. This enhancement prevents Sahi's internal 'sahisid' cookie from being accessible across domains. Consequently, Sahi's playback fails on the very first statement with a 90-second error.

Issue 2: Firefox's captive portal detector regularly connects to http://detectportal.firefox.com/canonical.html. This opens an additional browser tab during Playback.

Issue 3: Firefox opens its hello dialog on every launch.

FIX: To handle the above mentioned issues during Playback, please follow the steps below.

• Take a backup of <Sahi Pro>/config/ff_profile_template/prefs.js
• Add the below lines in <Sahi Pro>/config/ff_profile_template/prefs.js

user_pref("network.cookie.cookieBehavior", 0);
user_pref("network.captive-portal-service.enabled", false);
user_pref("browser.startup.upgradeDialog.version", 89);

• Delete the <Sahi Pro>/userdata/browser/ff folder.
• ‍‍Restart Sahi Pro and check.

‍
The fix needs to be applied on versions Sahi Pro 9.1.2 or lower. This fix will be present in our upcoming releases.
