Comcast Web-Mail Filters No Longer Accessible after FireFox Update (New Title)

more options

Sometime in the past month (after version 18, I think) two apparently unrelated problems have arisen:

1) I can no longer access my e-mail filters in my Comcast webmail accounts with FireFox. Although e-mail works fine, when I navigate to the relevant preferences page (http://web.mail.comcast.net/zimbra/mail?app=mail#3), none of the links work. This was never a problem in earlier versions of FireFox, but now I have to use IE8 to make these changes.

N/A -- See below: 2) I have successfully used the NoSquint add-in for years to set site-specific magnifications on Web pages in FireFox. Now it will change the magnification on any page, but the new magnification applies to **all** pages and is no longer site-specific. I updated FireFox to vs. 20.0 and NoSquint to vs. 2.1.7, but this has made no difference.  :N/A -- see below.

Since both of these problems appear related to a FireFox update, I'm posting this question here. -- JCW2

...OK, so what I didn't say is that I'm using NoScript in FireFox. I got the following idea form somebody mentioning that you have to enable JavaScript for Comcast WebMail. Although I had always allowed comcast.net, of course, and (apparently for some other reason) also yahooapis.com, now I also have to allow ajax.googleapis.com in order for these preferences features to work. Experimentation shows that **both** of these external sites must be allowed in NoScript in order to use the email-filters feature. I don't imagine that either of these sites is especially pernicious -- any guidance on this? -- but I hate to let Google and Yahoo watch **everything** I do!

Apparently Google continues to take over the world... -- JCW2

Update: Since I posted the above, problem (2) has magically (as in, I didn't do anything that I know of) disappeared! The more vexing problem (1) remains, however. I'll try Comcast too, but I already know that they will say it's FireFox's faullt... -- JCW2

Have you tried the standard guidance?

When you have a problem with one particular site, a good "first thing to try" is clearing your Firefox cache and deleting your saved cookies for the site.

(1) Bypass Firefox's Cache

Use Ctrl+Shift+r to reload the page fresh from the server.

Alternately, you also can clear Firefox's cache completely using:

orange Firefox button (or Tools menu) > Options > Advanced

On the Network mini-tab > Cached Web Content : "Clear Now"

If you have a large hard drive, this might take a few minutes.

(2) Remove your comcast.net cookies (save any pending work first). While viewing a page on the site:

  • right-click and choose View Page Info > Security > "View Cookies"
  • Alt+t (open the classic Tools menu) > Page Info > Security > "View Cookies"

This will open a dialog where you can remove the cookies individually.

Then try reloading the page and logging in again. Does that help?

Good catch. Websites do change their designs. We probably should have overlooked the coincidence with the upgrade and paid more attention to the previous two months to pick up on it more quickly.
