Why is Firefox 7 Beta so slow and lags or locks up and crashes? 的最新解答https://support.mozilla.org/zh-TW/questions/8679042011-11-02T02:32:38-07:00don't bother because if you use that version it is just as slow. Maybe if you uninstall 7 yourself 2011-11-02T02:32:38-07:00skostekhttps://support.mozilla.org/zh-TW/questions/867904?page=2#answer-268792<p>don't bother because if you use that version it is just as slow. Maybe if you uninstall 7 yourself and then reinstall 5 it might work better. I never did an uninstall of 7 before I applied 5. None of it seems to work faster. Hate FF right now. Using IE9 and it is much faster.

<ul><li> Number of Connections
<ul><li> this affects only Windows users (that is that majority of course), it has been fixed in Firefox 8, there is a workaround to fix it in firefox 7 see <br><a href="/en-US/kb/websites-show-spinning-wheel-never-finish-load#w_lower-the-max-number-of-http-connections" rel="nofollow">Websites show a spinning wheel and never finish loading</a>#w_lower-the-max-number-of-http-connections
</li></ul>
</li><li> A problem with the bookmarks database
<ul><li> again already fixed in firefox 8, and having a workaround in firefox 7 see: <br><a href="http://blog.bonardo.net/2011/09/30/is-your-firefor-freezing-at-regular-intervals" rel="nofollow">http://blog.bonardo.net/2011/09/30/is-your-firefor-freezing-at-regular-intervals</a>
</li></ul>
</li></ul>
<p>The developers appear to have realised that this sort of thing should not happen or slip past testing, they are I understand, working on a method of automatically reporting these hangs as a matter of urgency (Bug429592).
</p><p>Please also note it is best not to download firefox from third party sites, it does sometimes result in inconveniences like unexpected add-ons, and also note that Firefox 3.6 is the version that should be used if you need an earlier version of firefox, it is still supported and secure. Versions 4, 5 and 6 may put your system or personal data at risk.

Since this updates madness started, the browser went through some great changes, but it is a shame that it doesn't give any time for add-on developers to make the necessary adjustments for proper functioning and neither it maintains compatibility with older versions of add-on's. Besides, I am a massive user, always working with many opened tabs at a time, doing research, reading social network, consuming media. Facebook: Terrible experience. Youtube: Even with only 2 or 3 opened tabs, and cache free, videos suffer veeeeery terribly, totally, annoying freezes... All the time... And this is driving me mad...

I have used FF for over two years now, with Facebook... now it has bombed BIG-TIME! I have had to go back to IE because the new Facebook update of October, 2011, will NOT work with Firefox.... well, it takes 20 seconds to load, freezes up constantly.... or crashes. Also, I have the supposed latest and greatest version of Firefox! Finally, I have high speed internet with a mega-fast computer... with an i7 chip, 18 GB of RAM, and Geforce 470 1GB video card! So.... what's up Firefox?! Back to Internet Explorer we are all now "forced" to go.&nbsp;:-(

the older versions of Firefox can be found on this page and site:
<a rel="nofollow">ftp://ftp.mozilla.org/pub/firefox/releases/</a>
Be sure to shut off automatic updates after downloading and installing
an older version; also be aware that some of the apps won't work, for ex: Google Toolbar. (~If I have to look at that little "trying to connect circle" one more time in the upper left-hand corner, I WILL be heading for a BAR! Ha!)
Other helpful and useful things can be found on the main page
Good luck,
and best of browsing to you!

Why did they change the value to 248 from 42 or whatever it was? Seems like it made everything slow, i bet it was to enhance something that .00001 % (probably nobody) uses. so everybody suffers because some developer wanted something that only he would benefit. great

I thought my computer had a virus but after doing some research realized it was Firefox. I HATE to even get online now. It would freeze for upwards of 30secs and would freeze up every 10-15 minutes it seemed. Now since 'upgrading' to 7 day before yesterday...I can be on a page for just a few minutes before it freezing up...for literally 2 minutes. I'm starting to really get pissed off and would REALLY appreciate a reply to let me know someone is ACTUALLY looking into this and having the same issues I'm having. I have been using IE...which I HATE...Google Chrome won't even open after I download! I have been using Firefox for SEVERAL years now...PLEASE FIX THIS ASAP!
