'Firefox' pulldown menu button (Orange one) very unstable 的最新解答https://support.mozilla.org/zh-TW/questions/7966122011-04-04T07:25:56-07:00AZoutback...so far today your suggestion of turning off hardware accereation has worked without any 2011-04-04T07:25:56-07:00jimschaubeckhttps://support.mozilla.org/zh-TW/questions/796612#answer-161871<p>AZoutback...so far today your suggestion of turning off hardware accereation has worked without any issues. I'm hesitating because for the longest time I was frustrated with the new Firefox. The new GUI is <strong>outstanding </strong>but the menu problem had me back on Safari and IE. So far so good today.

And I have stumbled upon a two stage procedural workaround that works reliably for me. First stage is to open a second firefox window as soon as firefox starts running. Then, each time a menu pull down (or pop-up) goes dead, I click on the non-active firefox window. I then immediately click to reactivate the window that had the menu problem. And the menu operation that had stopped working will then have normal functionality (at least until its next random malfunction)!

I really like the new interface. I deactivated all add-ons and one by one activated them. Strangely the problem has not returned. I can not even recreate the problem like I used to. Maybe one or more of the add-ons has been updated and no longer causes the issue.
