Hi ; Previously I was doing fine using Google Chrome ver4 stable and SRWare Iron 4 sandboxed. Even made Google Chrome my default browser. Never had problems really but the occasional 5 tabs allowed but it's okay with me. Now after I have just updated to Firefox 3.6.7 and Mamutu ver3 all of a sudden they both won't work in a sandbox. Both would go for long "Loading..." which seems like forever..when opening a new tab would not display right..I mean the thumbnails view..nothing..after which they would crash! When I uncheck "Force Google Chrome to run in this sandbox(Registered version only)" or "Force SRWare Iron to run in this sandbox(Registered version only)" they are good to go. With Firefox 3.6.7 / Opera 10.6 / IE8, no problems running them sandboxed. Just both Chromium based browsers. Is somebody experiencing this also? What can I do or check to make it work again? I tried uninstalling Sandboxie 3.46 and reinstalling 3.45 but it still was the same. Will unchecking "Drop My Rights" in the Settings tab be advisable? I don't want to but I'd like to ask if I do that what is the scenario? I mean what will I miss if I do that as compared to leaving it "checked"? As mentioned earlier, I have never had problems before running inside a sandbox (both have their respective sandboxes). I also use the tips here at wilders' about the sandbox configuration recommendation of ssj100/andyman35/sully. I have Avira Premium Security Suite ver10 -realtime (w/o firewall/Proactive) / Outpost Firewall Pro--realtime with IP Blocklist and MVPS host file/ Malwarebytes free / HitmanPro Build 107 / SASpy free / Mamutu ver3(not always on). Sandboxie 3.46 paid. Please help me on this. Thank you very much!
