> does not load all the restored session tabs at once either

As someone who always has too many tabs open, I consider this a plus.

I do however think you can disable this in about:config : browser.sessionstore.restore_on_demand

also, if you use Autodiscard plugin, you will find that FF use less RAM and Ru. more faster. Essentially discard and suspend tabs that you aren't using.

Laying all the trans at one cripples my core i8 system for some time. Firefox's lazy tab loading is a much better user experience. Together with TreeStyle Tabs and the recent multi-container add-on, Firefox is just a better experience.

I used to be a fanatic about tree style tabs, but due to the new api, it's unusable with containers. I recently switched over to vertical tabs for that reason. I miss the tree layout, but at least now my tabs maintain their ordering.

All of my TST issues have been related to the layout cache. You can disable it if you right-click the toolbar icon.

Thanks for the heads up. I'll play around with it sometime later this week. I would love to have it working consistently again.

What are you talking about? I've been using TreeStyleTabs with containers for a good year or so.

I'm sure you're aware that not every user will have the same experience with a piece of software. There are a couple of bugs referenced in the Github issues for TST relevant to containers. There is a workaround, but I experience the issue again within a half hour. Not worth it to me.

Alright, it's just that the phrasing - blaming it on the new API - made it sound like an inherent flaw that would affect everyone, which definitely isn't right.

For what it's worth, Chrome stopped doing this for me in a recent update (I think version 71).

.. and Chrome doesn't have container tabs, which for me are a killer feature.
