perpetual lockups

I installed the latest FPR 4 two days ago, but it is unusually slow on my G5/ 10.4.11 with perpetual lockups. Very annoying as I have to quit and restart the browser though shortly afterwards it slow down againg to the point it is impossible to browse a page or type text as now - each letter appear after eternal delay.

Can I uninstal FPR 4 and instal the previous FPR 3?

Let me know please. Thank you.

    Although I use the browser on a daily basis, and I haven't received any other reports similar to yours, you can return to FPR3.

    It would be interesting to hear about whether the situation improves when you re-install FPR3. Download here:

    Thank you for the swift replies.

    I will download and install FPR3, and let you know by the end of the weekend.

    I down loaded the FPR3 myself and found it worked much better than the FPR4. I have a iBook G4 and it was constantly freezing. Works much better now.

    If either of you can provide specific sites it occurs on, I can have a look.

    If it occurs generally or without a specific pattern, I can't reproduce that on any of my machines, including my own iBook G4.

    Ron Norman's Avatar and Drudge were two that I remember, it seemed it happened a lot on the start up page what ever it was.

    Installed the FPR 3 and so far, an entire day in use, it remains much more responsive that FPR 4.

    All iterations of TFF slow down eventually and need quitting/restart (I tend to keep open several windows at the same time and probably this is the culprit), but FPR 4 was unusually quick - just a few hours in use - in becoming unresponsive.

    The slowest loading site I ever came across is Google Maps: sometimes, when TFF gets bogged down and needs quitting/restart, Google Maps page download only partially and then freeze; or download it its entirety, but doesn't respond anymore.

    Thanks again for the help!

    Yes, TenFourFox certainly does accumulate cruft after awhile (this is not a TenFourFox-specific problem; regular Firefox also does this). Multiple open windows and tabs can make it worse, though you'd probably need open windows in the double digit range to be the cause. Some of the local changes I've made were to make garbage collection more deterministic but there were no such changes between FPR3 and FPR4. For the record, on the G5 I'm typing this on, I have about 7 tabs active and 43 tabs idle and it has been running since November 9 (i.e., 17 days of the browser running continuously without sleeping or restarting). I don't have any beachballs or slowdowns currently as I type this.

    I did try both sites Ron suggested, but I'm unable to find a quantifiable difference between FPR3 and FPR4 on the test systems. It's possible your systems are configured differently to mine, of course. I didn't receive any reports like this during the testing phase of FPR4, and at least some feedback that the browser was noticeably faster, so I can't clearly determine exactly what's going on.

    That said, I'll leave this ticket open to see if there are other reports or if you discover something additional. If there is a site that is consistently problematic and is clearly better in FPR4 than FPR3, though, that could be helpful to know (but again, I'd need to reproduce it in a controlled environment to be able to do anything about it).

    Thank you for the detailed reply.

    Apparently my set up is to blame.... With that in mind, FPR 3 still performs better on my machine.

    Thank you for the good work!
