Description

[Rubens Takiguti Ribeiro]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; pt-BR; rv:1.9.1.3) Gecko/20090824 Firefox/3.5.3
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; pt-BR; rv:1.9.1.3) Gecko/20090824 Firefox/3.5.3

"Search in page" tool push visual components (of the right margin of browser) to the right (about 1cm) and a slice of them gone hidden when I click to search next occurence and it is the last occurence of text in page.
In fact, the visual components are expanded to a width that is not supported by the size of the window.
The vertical scrollbar gone hidden completely.

Reproducible: Always

Steps to Reproduce:
1. Go to a website with vertical scrollbar
2. Type Ctrl+F (open search in page tool)
3. Type a word that has at least 2 occurences in the page
4. Click on (search) "Next" until the last occurence of the word in the page
5. Click on (search) "Next" once more time
Actual Results:  
Visual components are expanded to a width that is not supported by the size of the browser window. The vertical scrollbar gone hidden.

Expected Results:  
Visual components should stay intact.

I am using:
OS: Fedora Core 7 (linux);
Browser: Brazilian Portuguese version of Firefox;
Screen Resolution: 1152 x 864;
Browser components: Web developer and YSlow (but when I turn them disabled, the problem persists)
