Before this, RSS pages were displayed in the browser window with a nice formatting as a content.
On an RSS page, I accidentally checked
Always use Live Bookmarks to subscribe to podcasts. and then the
Subscribe Now button. (Note that I have a non-default dark theme in Firefox, but this is still just native Firefox.)
Now every time I visit the RSS page, the content is
not displayed, and all I get is a dialog titled
Subscribe with Live Bookmarks.
I searched on the Internet, and I found that I should go to the Tools menu (in F10 or Alt + T), select Options, then on the Applications tab I should filter to Web Feeds and set it to Preview in Firefox.
Now here is my problem. I still only get the dialog titled "Subscribe with Live Bookmarks". I've tried to disable all Add-ons from the Help menu and start Firefox in safe mode, but it didn't help. I've even tried to delete the live bookmark I added, but it didn't help neither.
My Firefox version is 17.0.1, I'm running on Windows XP pro SP3 32-bit, my user is administrator, I have all rights in the Mozilla folder in Appdata, and I have more GB free disk space.
What should I do to make Firefox display the RSS pages again as content, instead of bookmarking?
