I have been getting his error for a very long time now:

you have chosen to open (web address here) which is a: application/octet-stream ehat should firefox do with this file? open - save

i got this from firefox 3, i tried completely uninstalling it, and then reinstalling it

and the same thing happens in firefox 4, which i just uninstalled firefox 3 and did a clean install of firefox 4

it happens randomly and periodically, it seems each new session resets the warnings, and when i click on about 35% of the websites in my speeddial, it will load that warning and a blank tab, after i click the speeddial again, it will work for that site, for the rest of the session..

it seems completely random, sometimes its google.com, sometimes mozilla.com, it could really be anything..

it could be a website in my speeddial, but it also happens sometimes when typing from the address bar

i have done extensive spyware sweeps, and antivirus sweeps for anything out of the ordinary, and i even repaired Windows XP SP2, and then I even upgraded to Windows XP SP3, i have all the updates, etc..

I have 2 computers on this network, and they both do it.

its really driving me crazy.. i even thoght about wiping my entire hard drive and reinstalling XP, but i dont want to do that

i tried IE8, but i hated the lack of speedials and tab options

and I tried Opera but i hated the fact that there were no multiple speedial tabs

and im not fond of chrome or safari for similar reasons..

i've tried a few things i've found online, but nothing really applies to this problem

does anyone have any idea how to fix this so i can keep using firefox?

i use the following addons:

Lightshot, Tiletabs, Tab wheel scroll, Tab Mix Plus, Speeddial, Fast Video Downloader, All-in-one Sidebar, two-pane bookmarks


thanks

I've also tried disabling all other add-ons, including the Speeddial, restarted, then as soon as i typed, "Google.com" the same thing happened

and I get messages for common file types too, such as "PHP", etc..

but it only happens once per session, per page, for about 25 % of the pages or links from other pages that i visit

they are really common sites, any site.. and the files are anything from common recognizable file types, to really long url's and strange file types i've never seen..
