BlockSite {web link} BlockSite is an extension, which automagically blocks websites of your choice. Additionally, this extension will disable all hyperlinks to these websites, by just displaying the link text without the clicking functionality.

Sometimes a problem with Firefox may be a result of malware installed on your computer, that you may not be aware of.

Block site works very well. But you need to be careful on how you tell it on what to block. If you want to block the site; xyz.com, add *xyz.com* to block everything. But if you only want to block part of the site, that gets a bit tricky. Note: Block site can stop a site from loading, but it can't stop a page / tab from opening. But it will be blank.
