Firefox behaves oddly when closing a tab

more options

Recently, when I close a tab, instead of showing the tab immediately to the right, sometimes Firefox will show the tab two to the right for less than half a second, then switch to the one to the left (the one that it should display in the first place). I haven't been able to figure out a pattern to the tabs or pages that this happens on. Only the page is displayed, the actual tab switches to the proper one right away. Here's an example if I'm unclear: I have tabs 1, 2, and 3, in that order. I close tab 1, then tab 2 flashes on the page briefly, and then it goes to tab 2 as it should.

This happened

Every time Firefox opened

== Within the last week, no new addons or updates

Do you have that problem when running in the Firefox SafeMode? http://support.mozilla.com/en-US/kb/Safe+Mode Don't select anything right now, just use "Continue in SafeMode."

If not, see this: http://support.mozilla.com/en-US/kb/troubleshooting+extensions+and+theme...

So, the problem had stopped for a while, but is now back and worse than before. Sometimes it will skip two tabs over, and it will linger on pages for longer. This problem does still occur in safe mode.

I often have multiple tabs loaded from an RSS feed. Often but not always, I close tab1, tab1 closes, tab2 becomes the current tab, the CONTENT of tab 3 displays, then the content of tab 2 displays. The time delay is variable & also depends on how many tabs have been loaded. One site that usually shows this symptom is makeuseof.com.
