227821 - Preference to adjust font size on all pages

Status: RESOLVED DUPLICATE of bug 108391

(SeaMonkey :: General, enhancement)

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.6b) Gecko/20031202

We need a way to adjust the size of all fonts on a page.  In preferences, this
should go under Apprearance -> Fonts: Adjust font sizes by [ ].  In the
brackets, default is 0, and we should be able to select +1, +2, +3, -1, -2, -3, etc.

A +1 should act like hitting <ctrl +> on the web page, adjusting the size of all
fonts. A +2 should be like hitting <ctrl +> twice, etc.

This is useful for people who require larger fonts to read.  It's better than
using a minimum font size, since it proportionally changes all fonts on the
page, rather than just the text that's too small.  It also tends to render some
pages better. (www.yahoo.com renders better with font size +1 rather than
settings a minimum font size.)

Reproducible: Always

Steps to Reproduce:
1. Go to www.yahoo.com and hit <ctrl +>
2. Hit <ctrl -> to bring it back to "normal"
3. Adjust the minimum font size to 15

Compare the lower part of the page, where there's supposed to be a difference in
the size of "Business & Economy" and "B2B" below it.

Actual Results:  
The heading "Business & Economy" is the same size as "B2B", while the author
meant it to be bigger

Not a Parser bug

This might be a duplicate of bug 108391; at least, I think it would have the
same end result.

This has been previously ruled a WONTFIX.  See bug 65571 comment 3.

It looks to me like that bug was wontfix at one point, but then was reopened and
later duped to the bug I mentioned, which is still open.

Bug 108391 - text zoom should be remembered across browser sessions, per-site
Bug 65571 - Text Zoom setting should be remembered (per-site) across browser
sessions

Bug 65571 comment 3 states that we should adjust the minimum font size.  That
tends to distort web pages by bringing up the size of all text that was below
this size up to the same size.  This means that you may lose the relative size
of small text.  This bug is supposed to be an alternative to "Minimum font size".

Bug 108391 would solve this problem, but would (I would think) be more difficult
to solve, since it has to keep track of a list of web pages and their zoom
characteristics, or put the information in the bookmark of the file, which would
only make it work for bookmarks.

What we really should do is create a main toolbar button, right next to back,
fwd, reload, stop, and bookmarks, just as Jakob nearly says:

I think if dbaron were to see this he would say dupe of bug 4821, or worksforme,
as the pref for font size theoretically does what the reporter asks. It just
doesn't work on pages sized according to the designer's belief we all have our
prefs set too big for our own good, e.g. our own http://www.mozilla.org/.

Reporter, putting 'body {font-size: 100% !important; line-height: normal
!important;}' in the file userContent.css in your chrome directory will help
your plight on many pages.
