A few days ago things on tumblr started going haywire: all hyperlinks would disappear (and only reappeared when I would navigate to a new page / refresh the page), hyperlinks wouldn't follow through after being clicked (especially troublesome on the dashboard with reblogging), and the "inspect element" bar would randomly appear when the reblog link did follow through, which sometimes even doubled the post being reblogged/edited (so that the HTML code and the rich text editor functions were being shown at the same time in consecutive windows). The final straw was this morning, when the "change blog" ability (in the upper-left-hand corner of a post being reblogged) stopped working. It will display the different blogs, but you can't select one to change where the post will be reblogged. Also, the editing hyperlinks have vanished completely on the dashboard. At the same time that I started having these problems, a blank bar appeared at the bottom of my new tab page (it doesn't do anything, it just sits there and annoys me) and the link on the new tab page for an add-on I have ("Customize about:newtab") disappeared. I don't know if these are related, but they happened at the same time. I have XKit 7.4.4 and Tumblr Savior 0.4.12 installed, and my anti-distraction add-on (LeechBlock) will block the site at certain times, but none of them are malfunctioning (I've checked) and there aren't any other add-ons that affect tumblr specifically. Thanks.
