DealCabby

These Firefox add-ons block "advertising opportunity detection" elements that are not usually blocked by Firefox:

Several Firefox add-ons of interest:

AdBlock Plus ... allows the sneakier counters and trackers to watch you. Add it on and you will be asked which "list" to subscribe to. I was advised to use "Easy List". It is a list of better-known adware trackers. When running, for me, it is a bar at the bottom of the browser, which shows something like "1 / 3" blocked. Yuo can then block or allow by mousing over that bar.

Ghostery ... makes you "invivble" to tracking you choose to not be tracked by. When someone like "DoubleClick" cn see you, a box in the upper right part of the browser will show the site in bright white letters. When you choose to block it, it becomes grayed with a line through it to show it is blocked.

Better Privacy ... Flash players like to leave cookies in its "application space". This space is beyond Firefox control, so these cookies stay behind. BetterPrivay will remove these "other" cookies and tell you it did so when you exit Firefox.

HTTPS Everywhere ... forces Firefox to first try an https connection to a site when in publicinternet spaces. It will default to http is no https is available.

NoScript ... blocks Java/other scrits in browsing. A bit annoying, as it tends to block first, then you must allow. But not too annoying.

Tracker Block ... blocks tracking. Do not se much interface for it yet, but I might yet.

Click&Clean ... no sure what it does yet but will figure it out.

WOT ... who to trust. Gives a status box in the upper left part of the bar telling you if a site you are in is not trustworthy.

Flagfox ... shows a flag to show what country the server is you are using.

Certificate Patrol ... tells you what certificates are loaded, allowing you to block if th site will still work.

Also ... go to http://winhelp2002.mvps.org/host.txt

This is a "hosts" file that lists knows virus sites. If you system tries to access one of those, this hosts file redirects the site address to "home" instead of the target. Re-download every few months for a new list of 15000+ sites that are bad.

I have the same issue and emailed DealCabby who told me they 'don't work on Mac' - which is funny considering it's on my Mac!

I, also, use Firefox, tried all the add-ons you suggested, did the CC Cleaner, uninstalled and re-installed, etc. Nothing. It's still there. Safari also seems fine with me as well so it appears to somehow be just a Firefox issue.

I never even heard of DealCabby until suddenly is popped up while I was editing a website. It also will open a new window in a re-direct when doing a Google search.

If anyone has come up with a solution or has an idea who to completely remove all traces of Firefox before re-installing please let me know. I'm somewhat tech literate but not code-level.

Thanks.

Same issue here. I don't think I've added any FF Add-Ons as of about the time when this first started happening, seems to have become an issue for me when Firefox automatically updated itself to v.15

This is sooooper annoying...

So I pretty much knew it wasn't a computer issue, rather a Firefox issue (or an add-on/plugin for Firefox). After going through each add-on/extension one by one, then revisiting a webpage where the ads from Dealcabby were popping up and checking to see if they were still there, I found the problem to be a Firefox Extension called "SaveAs 2.4" by:JustPlugIt Immediately after I disabled this Extension (which of course was the very last one I tried), then restarted Firefox, the DealCabby ads were gone!

Hope this helps, as I have been so infuriated the last couple days...not sure why I didn't think of this sooner, but I don't remember downloading any FF Extensions recently so it didn't cross my mind.

Be aware that disabling the Flash Plug-In will also solve the issue, but this is a false-positive, since the Ads require Flash to work, and this is not the root cause of the hijack.

Thank you so much! Disabling "SaveAs 2.4" fixed it immediately for me. I appreciate it!
