Created attachment 8374542 [details] Glitch.png User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:27.0) Gecko/20100101 Firefox/27.0 (Beta/Release) Build ID: 20140127194636 Steps to reproduce: -Install extensions Autopager or Autopagerize from the addon site. -Create or use a rule for the addon site such as https://addons.mozilla.org/en-US/firefox/extensions/?sort=users -Scoll down the end of the list so that the next page is added. -Continue until the problem appears (for this example, it's when the 14th page is added) Actual results: The boxes around the text turn black either when they suddenly appear or when the mouse is over them. They do return to normal when I scroll away and then scroll back, but they'll turn black again as soon as I mouse over them Expected results: I should see these elements load normally.
Could you paste here the graphics section of the page about:support please.
(In reply to Alice0775 White from comment #1) > Could you paste here the graphics section of the page about:support please. Certainly. Check the attachments section. And FYI, while the png file shows the Pale Moon browser, I did test the bug on the latest official version of Firefox, and it has the same issue.
Update: I've discovered that this bug occurs when the window is shortened to a certain size. And it still prevails in the new Australis theme.
Severity: normal → major
