A lot of us use url/cookie/etc cleaners and restarting the browser forces us to log back in to sites that we'd rather not want to during the current browser session. OR have the browser set to just delete everything at close.

1) if you want to keep the session, why do you use a session cleaner? 2) how hoften do you install new extensions? Is this really a problem?

I leave browsers open for days/weeks. I save anything I think I'll need to bookmarks or pocket. I like having it wiped when I close it. Which does force me to log back in to email/reddit/HN/etc. I have encrypted applescripts for that though so it's not too annoying.
