Unfortunately that's not that easy and we already have a workaround. I expect more apps to be broken because of this bug than apps depending on the single process model. I know it would be ideal if apps didn't have to do anything, but we have a very simple workaround for the single process model case. This bug is more complicated and the only way I see right now to not break apps is disabling PSON.

It's a pity that very few people try early unstable releases, and I didn't notice any issue because I don't use the remember password feature of ephy.

I guess it will be slower to load pages when switching processes due to history navigation (which is always expected to be fast).
