981655 - changing tile pref's to negative numbers causes stability issues

Status: RESOLVED INCOMPLETE

(Firefox for Metro Graveyard :: Firefox Start, defect)

Description

[Kamil Jozwiak [:kjozwiak]]

When you set any of the preferences listed below to a negative number, you'll run into issues when loading websites while the browser tries to update the tiles under about:start. We should either not allow users to set the preference to a negative number or make it so a negative = 0.

- browser.display.startUI.topsites.maxresults
- browser.display.startUI.bookmarks.maxresults
- browser.display.startUI.history.maxresults

Attached video of the issue:
- http://youtu.be/KPjmvgExKaI

Steps to reproduce the issue:

1) Open fxmetro
2) Change any of the preferences that are listed above to a negative number (usually I get the best results setting the history pref)
3) Once you've changed the preference to a negative number, load any website

Current Behavior:

- The above preferences can be changed to negative numbers causing stability issues (fxmetro stalls)

Expected Behavior:

- User's shouldn't be able to change the preference to a negative number and should never stall fxmetro to the point were its not usable anymore

Issue found using the following build:
- http://ftp.mozilla.org/pub/mozilla.org/firefox/nightly/2014-03-10-03-02-01-mozilla-central/
