after yet another ff crash, I forced an update to the latest release today. THAT was a mistake. Before, ff was simply unstable. Now it's so slow it's unusable. It's like running Windows 8 on an IBM XT.

Given that I'm running Win7 on an Intel i7 3770 w/16gb of RAM, and a loaded graphics card, pretty sure that I'm not the problem.

You guys REALLY need to fix the stability. I'm having to use Chrome to write this, since FF is so unusable right now.

Hello,

I had similar problems. I am using Windows XP Pro 32 bit. I am using Internet Explorer to ask this question, as my computer will not open the FF browser. What do I do now, please? In plain English please, I an old & not a techie....your answer to this person meant nothing to me...Oh, I did try a restore point, but that didn't work, Do you think I should reverse the restore point? Then how do I get to open FF? Also, I must say, I did not like the new look of the new version. I spent 5 hours re-designing it all for nothing, what a waste of a day.... Is it ok to re-install the older version? Or is that a no-no? I am confused to say the least.... Kind regards Sylvia

Hi Sylvia

Which security software (firewall, anti-virus) do you have?

It is possible that your security software (firewall, anti-virus) blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.

Remove all rules for Firefox and the plugin-container from the permissions list in the firewall and let your firewall ask again for permission to get full, unrestricted, access to internet for Firefox and the plugin-container process and the updater process.

I have the same exact problem. I'm a firefox user since the first version, and always have experienced ups & downs in performance and stability.

Latest releases result in too much instability (at least 2 or 3 daily crashes) up to v29.

With v30.0 the problems are aggravated:

Crashes continue, but now there are huge memory leaks and sluggish user experience (it freezes for a fraction of a second every 2 seconds!!!)

This happens after some time (hours?) after a fresh start (that i MUST do every couple of hours to make it usable).

Firefox is going the wrong way...

I fixed the Firefox v 30.0 slowness issue on my MacBook Pro running Mavericks after doing 3 things:

1. Executed the recommended Firefox reset (it didn't complete, however) 2. Found that Preferences > Security & Privacy > Firewall didn't explicitly 'Allow incoming connections' for Firefox. I added Firefox to the list and set it to 'Allow incoming connections ' 3. Disconnected my Cisco RE1000 range extender because it was creating so many other network problems (dropped connections on several devices) and I suspected was slowing down my network.

The result for me was likety split fast Firefox and the most stable network (although not as broad as I would like) performance I've had in months.

After disconnecting the RE1000 my speedtest download results went from an average below 10 Mb/s to 14 Mb/s on two tests taken a few days apart. Upload speed increased modestly with this change (1.75 to 1.95). I now need to find a better wireless extension strategy and am considering a powerline with access point solution.
