639839 - Page zoom not kept between page navigation

Status: NEW

(Firefox :: General, defect)

Description

[Jasper St. Pierre]

User-Agent:       Mozilla/5.0 (X11; Linux x86_64; rv:2.0b13pre) Gecko/20110308 Firefox/4.0b13pre
Build Identifier: 4.0~b13~hg20110308r63349+nobinonly-0ubuntu1~umd1~maverick

When reloading a page in the same domain, the zoom size should be kept. Right now, for a number of sites, it resets the zoom size.

Reproducible: Always

Steps to Reproduce:
1. Go to http://google.com/
2. Press Ctrl-+ to zoom in
3. Go to http://google.com/search?q=foobar
Actual Results:  
Zoom size went back to 100%.

Expected Results:  
Zoom size should be kept per-domain.

This started happening at most a week ago.

Doesn't work on all sites: BMO is working properly, but it fails on other HTTPS sites.

The bug also has the effect with a hash, like: http://google.com/# -- so AJAX sites that use this to navigate are quite annoying for people with bad eyesight like me.

Still happen in safe mode / with a clean profile?

Failing that, can you find the regression range please:

Safe Mode doesn't work, but a clean profile does.

Does copying your prefs.js from the profile that doesn't work to the one that does make it also not work?

Comment 4

[Jasper St. Pierre]

It seems to be content-prefs.sqlite that causes the bug.

Comment 5

[Boris Zbarsky [:bzbarsky]]

OK, definitely not a core text rendering issue...

Comment 6

[Jasper St. Pierre]

Do you guys still me to do a bisect?

Comment 7

[Boris Zbarsky [:bzbarsky]]

That would be useful in pinning down the problem, yes...  Make a copy of the content-prefs.sqlite first, so the bisecting doesn't mess it up?

Comment 8

[Jasper St. Pierre]

OK, it looks to just be a corrupt content-prefs.sqlite, not a regression.

$ sqlite3 content-prefs.sqlite
sqlite> SELECT * FROM groups
1|bugzilla.mozilla.org
...
673|bugzilla.gnome.org
Error: database disk image is malformed

Still, you should probably do something about that.
