That's your problem, right there.
I've been told that the main version of LastPass currently available from addons.mozilla.org has known problems that cause the browser to lock up and hang indefinitely.
Instead, if you click through to list all releases and select the latest 4.x version, those problems should all be fixed:
https://addons.mozilla.org/en-US/firefox/addon/lastpass-pass...
That's odd - it turned out I had version 3.3.2 installed, I wonder why the auto-upgrade didn't happen? Are the 4.x versions beta releases?
Yes, IIRC. They're still imperfect and can lag the browser quite a bit IME, but what can you do... Switching to a different password manager is not easy, and the ones I've looked at all have this/other problems.

SafeInCloud. That's what one can do.

I think those of us using LastPass stick with it because no one better supports Linux. It looks like SafeInCloud is yet another option with no Linux support.

My worst problems were with Toptal's website. I even tweeted them about it, but it still leaked memory like crazy. Maybe they fixed it already, but I wouldn't know - they didn't have articles that interest me in a while.
Anyway. I have Firefox with uBlock, on Archlinux. With JS disabled. 400MB, about a hundred tabs. I do recommend using it that way. I also have Chromium, for things that require JS - youtube, facebook and the like.
How can a site leak memory? Javascripts is garbage-collected.
Easy: add it to something that's alive while the site is alive. Here's an example that leaks some memory every 100ms while you have the site open:
window.leakyArr = [];
function leakStuff() {
leakyArr.push("This is leaked" + Math.random());
}
setInterval(leakStuff, 100);
Same setup, but my Firefox leaks memory like a sieve. It will crash 2x a day easily.
That said, I also have LastPass installed, I am using uBlock instead of ABP (though uBlock uses less memory anyway), and I also have RES installed.
I have seen websites leak incredible amounts of memory. To some extent I don't even know how much it matters what browser is used, if the JS is bad enough.
