This question is twofold:

  1. Does anyone else notice sluggish behaviour from Firefox 4 ("Minefield" daily build) when browsing Ask Ubuntu?
  2. If so, did you find a fix for this?

More details

  • I have just updated firefox again to make sure it hasn't been solved by now.
  • I have tried running in safe mode (add-ons disabled and the likes), but this did not change anything as far as I could tell.
  • I am not experiencing this on any of the other StackExchange sites.
  • I have not yet found a consistent pattern, though sluggishness mostly occurs when:
    • Scrolling through (slightly) lengthier topics, the threshold seems rather low. (example)
    • Typing in a comment. This one is especially annoying, I'll be typing a comment, but it takes a while for the letters to even show in the textarea.
  • This seems to occur no matter how long or short firefox has been running.
  • System load is neglectable.
  • This is not a new issue.

Could be helpful

Any knowledge on significant differences in, for example, background work in comparison to the regular stack overflow software.

I posted this on meta since it only seems to happen on this site.

  • I've had issues with some of the betas on some sites, but not with others. 4-Beta7 was fine, Beta8 bad, Beta9 ok, and Beta10 is killing me, again. (Reading more carefully -- I had stopped using the daily builds to try to escape some of this. But I've just got more stable failure or success now.) – belacqua Jan 28 '11 at 18:35
  • I have this problem too. But I use Firefox 4 only occasionally -- my primary browser is Opera. (This post is from Firefox and the system is really slow...) – Vojtech Trefny Jan 28 '11 at 20:16
  • It's fine to discuss this here but it is not a bug in our software.. – Jeff Atwood Jan 29 '11 at 3:47

    Bear in mind that Firefox 4 is not stable and is still in Beta. You should ultimately report this to Firefox as well since it may be a bug in their rendering engine. – Marco Ceppi Feb 1 '11 at 13:45
  • Closed as too localized, since A. Firefox 4 is out, and B. Stack Exchange only "supports" the stable versions of browsers, and at the time this was written, Firefox 4 wasn't released. – jrg Apr 12 '12 at 11:50
