303168 - Text does not resize at some websites

Status: RESOLVED WORKSFORME

(Firefox :: General, defect)

Description

[Ed Hume]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8b4) Gecko/20050801 Firefox/1.0+

At many websites, the text cannot be resized using ctrl-<+>/ctrl-<-> or View >
Text Size > increase/Decrease. See article above for a specimen. I have been
noticing this for at least a month.

Reproducible: Sometimes

Steps to Reproduce:
1. On certain websites, wait for page to stop loading
2. attempt to change text size

Actual Results:  
Text size does not increase or decrease.

Expected Results:  
Text size should increase or decrease.

At the site above - and other sites where this has occurred - the text is
resizable while the page is loading. If you set the text larger or smaller
during the loading, it remains at this size and cannot be changed without
reloading the page. Then it can be reloaded.

As at many of these sites, there is an ad on the right where the text is changed
while the main text is not changed.

The phenomenon has been confirmed by others. One even found a reversal of the
page's behavior - the ad's text was not changed where the main text was changeable.

I see this too.

Based on a comment in the forum thread, I tried 1.0.5 on the page. in that case,
the main page text was changed and the ad text was frozen.

Confirming Ed's comment, this WFM in 1.0.6. Investigating.

[Ben Basson]

Now this WFM - I don't understand. Looks like it's up to someone else to isolate
this. Sorry for bugspam.

[Ed Hume]

I just installed the 2005-08-02 build, and the test page WFM now, on both my
default profile and a new clean profile - no extensions, no themes.

?

This appears related to JavaScript. If it's relevent, the screen flashes white
once the page finishes loading (presumably an onload handler) and from that
point onwards I cannot resize the text.

I have noticed that when this does happen, that when I attempt to change the
text size, the change will happen on the other stylesheets (i.e., if I try to
change the text size and then go to View > Page Style > No Style (or back to
Basic Page Style if I was on "No Style"), the text got larger).

> the text got larger
Or, it will get smaller if I tryed to make it smaller.

[Asa Dotzler [:asa]]

There's a flash ad on this page and when it's visible, the frame of the flash ad
gets focus (sidebar advertising) then that frame's text gets resized and not the
main content. If you're blocking that frame, you won't see that the text is
actually resizing. If that flash ad isn't present, then you don't get focus on
that frame and thigns just work. not a blocker (possibly not even a bug)

Well, this appears to work just fine on the Aviary branch... I think it needs
more investigation before it can be ruled out as a bug. 

Besides, even if this is how things are meant to work, it doesn't seem
particularly desirable to let a website stop the user resizing the text (either
by accident or intentionally).

I don't understand parts of Asa's comment.  Why would only one frame have its
text size change?

Should that be an additional check box under Tools:Options:Content:Enable
Javascript:Advanced ?
