Firefox has been my preferred browser for years, but I have switched over to Chrome now because of certain things that Firefox suddenly will not do anymore that Chrome has no problem with. For instance, when I log into Hootsuite to handle social media for work, Firefox appears to block and prevent user icons and profile pics from displaying properly, showing just empty gray boxes in their places instead. My best guess as to what's causing this has been to deactivate Adblock, but doing so has no effect. @HootSuite_Help has tried to help me by suggesting I do things like delete Hootsuite's cache, but nothing works on their end. Since Hootsuite works perfectly fine on Chrome, it's obvious that this is a Firefox issue.

Any idea how I can fix this? I'd really love to be able to use Firefox all the time since Firefox has a MUCH superior system in place for organizing bookmarks than Chrome does.
