The LastPass and left/right arrows bugs have been fixed in Canary 76.0.144.0... at least for me

[NicolSD]

The bug that prevented LastPass to connect to its servers has been fixed as well as the left and right arrows bug. Might I suggest that if you still experience it in the latest Canary that you bring it up again? Just because it's working for me doesn't mean it's going to work for you.

We are aware of LastPass issues and are working to correct them.

@v-gapart  It looked like it was working back at the end of April but it didn't last long. A few builds later, it just broke again and it's still broken. I hope you fix it soon. It's an important part of safe browsing.
