795666 - Background thumbnail creation consumes lots of disk space

Status: RESOLVED DUPLICATE of bug 726347

(Firefox :: Untriaged, defect)

Description

[Lars Viklund]

User Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:15.0) Gecko/20100101 Firefox/15.0
Build ID: 20120725114759

Steps to reproduce:

Click the little button on about:newtab to disable the thumbnail view out of preference and privacy.


Actual results:

Thumbnails are apparently still generated in the background, judging by the half-gig folder in my local profile, containing files with recent dates and secret information.


Expected results:

Disabling the tab view should preferably stop the pointless resource waste in generating thumbnails in the background.

There is supposedly an unlisted config entry (bug 752407) to force-disable this generation, but that is not a solution for anyone but developers that are intimately familiar with the codebase.

Some of us work on very small home directories. Directories as small as a few dozen megs hurt already, let alone this half-gig (and assumedly growing) behemoth for a feature that shouldn't be enabled at all.

That should be bug 726347.
