972283 - Lightweight themes take a long time to load at browser launch

Status: RESOLVED DUPLICATE of bug 846184

(Firefox for Android Graveyard :: Theme and Visual Design, defect)

Description

[bull500]

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:30.0) Gecko/20100101 Firefox/30.0 (Beta/Release)
Build ID: 20140212030201

Steps to reproduce:

Installed - Japanese Tattoo persona theme
Launch Firefox and see a a lag to load the applied theme
Android OS 4.1.1


Actual results:

I always find a noticeable lag on launching Firefox for Android when a persona theme is installed.
It is more profound when the connection is slow, and the browser freezes till the theme is completely loaded(downloaded) from the internet.
Its a usability issue. Browsers should not lock up on launch to load a theme first.


Expected results:

The persona should be downloaded and stored on the Internal Storage or SD Card(External) 
It should NOT be downloaded right when the browser is launched.
Storing & Loading from the Internal Storage/SD-Card is a much better alternative and the persona can be updated in background after the browser is running stable.

No.

There's always been a lag, but it's not normally due to loading anything from the network. I can cold-launch with a theme while in Airplane Mode.

It's because our theme support is implemented in Gecko. If Gecko takes five seconds to load in the background on your phone, you'll be interacting with an unstyled about:home for five seconds, then your theme will load.

Try it out: cold-launch Firefox, hit the Menu button really fast. You'll see "Settings" is greyed out. Betcha that it un-greys at the same time as the theme is applied.

This issue was filed long ago as bug 846184. There was some work in that bug, but nothing ever landed.
