272878 - Something or some site unchecks the "Block Pop ups" box in options menu and freezes tabs in Options menu

Status: RESOLVED DUPLICATE of bug 262824

(Firefox :: General, defect)

Description

[Jim]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.5) Gecko/20041107 Firefox/1.0
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.5) Gecko/20041107 Firefox/1.0

When opening an article from an RSS news feed (usually, but not limited to
newsisfree.com/xxxxxx and CNN) pop up windows appear when page opens.
Immediately going to Tools - Options - Web Features will show the Block Pop up
Windows option as unchecked. When opening Options menu, if Web Features is not
the selected tab, clicking the Web Features tab or any other, gets no response.
If you close the Options window and re-open it, you can then select Web Features
or any tab with normal results. After doing so, you find the unchecked Pop up
box. This happens several times per week but I have not been able to isolate any
particular site or cause (other than as stated above that it's more frequent
with CNN and anything from newsisfree.com) This has happened since ver. .9xx and
continues into ver 1.0 which I just installed today.

Reproducible: Sometimes
Steps to Reproduce:
1.Open news feed links to CNN or newsisfree.com
2.Keep opening them until you get pop ups (you will eventually)
3.Check Tools- Options- Web Features and note if Block Pop ups box is unchecked.
Note if your tabs in the Options window are unresponsive.

Actual Results:  
I eventually get pop up windows and then find my previously checked  Block Pop
ups box (in Tools- Options- Web Features) is now unchecked. I also find my
Options tabs frozen until I close and reopen the Options window.

Expected Results:  
My Web Features options should remain as I set them and my Options menu should
respond to tab choices without closing and re-opening it.

This happens regularly and without me changing any settings in Firefox. e.g. Not
caused by installing an extension or changing any security settings. I have no
whitelisted sites. The only times I have entered Tools- Options in the past few
months, is to correct this problem when it happens. Otherwise, no
Options/Settings have been changed by me.

Jim, do you have Tab Browser Extensions installed?
