1191824 - Session restore fails to load tabs; drawer shows most restored as white thumbnails no titles

Status: RESOLVED WONTFIX

(Firefox for iOS :: General, defect)

Description

[Aaron Train [:aaronmt]]

* Install build #28 https://people.mozilla.org/iosbuilds/index-28.html
* Visit multiple sites, multiple tabs
* Update to build #29

Upon opening the tab drawer in build #29, all sites are just while tiles that don't load unless you tap each one.

We shouldn't break this on browser update.

I am going to close this as WONTFIX. I am fairly sure this is because we switched implementation of how tiles are displayed and stored so it would be a one-time upgrade issue.

I see the same thing just doing a regular session restore. Not sure if this is intentional or not, close the browser, re-open, see all tabs in the drawer wont load at all until you touch them. Why isn't the page cached?

This will happen after updating to a build with bug 1187176 since we changed the way screenshots are stored. It should only happen once (i.e., any new screenshots should persist).

We intentionally load tabs lazily to improve startup perf and reduce data usage (same as Firefox for Android).
