But the content screen flickers, made the reading of webpage become difficult. I typed the same URL in other browser and it's normal. This problem also happens when other webpage(s) is opening in other tab and switching from a flickering content's tab to the normal one's tab(making the normal one flickers also).

Does this happen in firefox's safemode? http://kb.mozillazine.org/safe_mode

(In reply to comment #1) > Does this happen in firefox's safemode? > http://kb.mozillazine.org/safe_mode > Yup. It also happens...But even not in safe mode, the problem's not neccessarily come out. You must try some things to make the problem happens.

I use Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.8.1.11) Gecko/20071127 Firefox/2.0.0.11 on a Windows 2000 machine. With the Bookmarks toolbar enabled, I see these issues:- The website contents flicker, especially the ads with images. Also, my yahoo mail (set to have the mail-client-look) has the right-click option failing. Without the bookmarks toolbar seen below the navigation toolbar, my yahoo mail allows me to right-click and perform different actions on any email. I checked that bug 247116 is related to a similar issue, but I noted that my bookmarks toolbar is not empty.

Anything from http://kb.mozillazine.org/Window_shakes help?

I had used the suggestion in point 2 : Unchecked the bookmarks toolbar and didn't see the issue anymore "If your Bookmarks Toolbar is showing but it does not contain any bookmarks, add a bookmark to it or hide it (View -> Toolbars -> uncheck Bookmarks Toolbar)"

This bug was reported on Firefox 2.x or older, which is no longer supported and will not be receiving any more updates. I strongly suggest that you update to Firefox 3.6.3 or later, update your plugins (flash, adobe, etc.), and retest in a new profile. If you still see the issue with the updated Firefox, please post here. Otherwise, please close as RESOLVED > WORKSFORME http://www.mozilla.com http://support.mozilla.com/kb/Managing+profiles http://support.mozilla.com/kb/Safe+mode
