More sleep, less work.

I encounter a very similar bug, but instead of being periodic, it tends to occur when accessing bookmarks or using the URL bar (especially with a keyword search). Any suggestions what to do? Your workaround has no effect on it.

It’s not the same issue, file a bug report in Firefox/Bookmarks & history, we may start from there.

Why wait as long as 8 (I know it’s only a month, but a month of freezes isn’t pleasant). Can’t you ship out 7.02?

Is this and the addon bug products of the rapid release cycle? How is it possible these got through the testing cycles?

We are evaluating 7.0.2, but those releases have usually different meanings. The discussion is still undergoing though.

No, this is not an effect of the rapid release cycle, the bug exists from at least Firefox 5 but the problem piles up slowly and it started hitting some users now. The tests coverage, while good, cannot find any single issue, it’s just not possible for the nature of software itself.

The bug 686025 specifies Windows and 64 bit. Platform: x86_64 Windows 7

The problem was discovered on Windows 64 bit systems is it only 64 bit systems that are affected?

Is there any point in users of Windows 32 bit installations trying this ?

No, it affects any platform, I’ll correct the report.

@nickers I think I have your problem, too. It also appears in Save Mode, but Firefox doesn’t freeze when using a new, clean profile. I’m using Chromium at the moment (Kubuntu 11.04 54bit). Did you file a bug report?

Hello
I tried your suggestion. I am still having issues.

This worked!!! I got a link to your blog on a Mozilla support thread and figured I would give your addon a try. I did clear out all my cookies/cache as well as did the steps listed in the blog post. I haven’t had a single freeze yet, and I’ve been on the net for several hours now.

Thanks for this! =)

Thanks for the tips. I followed your instructions but am still having isues. After years of using Firefox, I may have to go to Chrome…

This completely fixed the Firefox 6 and 7 issues that were happening on an OS X 10.7 machine. For the record, this problem only happened to me on 10.7, not 10.6.

Thank you!

I’ve noticed occasional freezing running FireFox 7. Moving my mouse seems to release the freeze. If I don’t move my mouse, after about 9 seconds it then frees up. I hope this helps. You’re all doing great work!

doesn’t fix my problem.
huge lag when accessing

every. single. time.
firefox 7.
multiple computers.

This did unfortunately not fix my issue. I’ve had the same issue with 5.x-8.x and before each new version I have tried I have done clean installs of firefox so nothing old is left to mess with different version. Also tried safe mode, does not fix it.

I’m still using Firefox 3.6 ‘cause all other versions are terrible crap.

Fixed my problem. Thank you! Found this as a last ditch effort as I was just about to give up on FF.

One fix that worked for me in FF 7.0 and Win XP

Type about:config into your address bar, accept the warning, type in the Filter box network.http.max-connections

Then double click on the network.http.max-connections setting and change the value to 32 (default was set to 256 from FF version 6.0 upwards).

Reducing that network max connections no. from 256 to 32 has made my FF very fast. Many others who did the same reported back success.

This problem had been driving me mad for a long time – until I found your blog and followed your advice. It did the trick and there have been no issues with Firefox for the last 48 hours – so thank you very much :)

Thank You! This worked great. I followed the directions above and it solved my issue. My bookmarks file is over 3mb (tons of bookmarks!) so I believe that it was the issue for “Places.” Now switching between tabs is fast, scrolling up and down pages is fast, and no more freezes. I’m soooo happy I have a web browser again!

I have this problem, for me it’s MOZCRT19.dll that’s using up all the CPU power, and neither the tip by this blog now the one by amkeew worked for me.

I am using Windows 7 64 bit. When Firefox freezes and stops responding simply click the red X (window close) button at the top right of the screen. It doesn’t close Firefox under freeze conditions but it does release the freeze immediately. I have no idea why,

Hello

I was hoping very much for this addon, but it does not work for my problem freeze
Occasionally a simple download a simple image upload leads to freeze. I am forced to move the mouse to close everything I’m doing to restart Firefox.
I’m running 64bit Windows Seven and after many tests, I noticed that only Firefox versions below 3.5.18 works. As against Windows XP 32bit installed on the same machine, the latest version of Firefox is working properly.

You can follow any of my tests to forum francophone http://www.geckozone.org/forum/viewtopic..

I still have not found a solution to today …

I have been bothered by this problem since upgrading to FF7, running on W7/64. Reading up on the bug link you provided, it seems like my issue. I will test it now.

Greetings and thanks from California!

I’ve just downloaded and installed the supposed ‘fix’ So far, after about an hour, no freezes. However, I have noticed that it seems to be worse when starting after, typically, an overnight. I have been running Resource Monitor which comes wth W7 to see what is hogging what, looks like Avast is the biggest hog. I’m not sure if this is relevant. OTOH, I certainly have never had the sort of issues some people on here seemed to have had – ignoring the obvious publicity con of the link to bronies…..;)

This seems to have fixed the problem for me. Many thanks. =)

Is there a reason this Places Maintenance addon would have trouble installing? I’ve tried to install it several times now, and it doesn’t get past a completely empty “Installing” bar in Add-ons Manager.

Cant even do that now. It’s gone from slowing down & freezing to crashing at boo up.

https://support.mozilla.com/en-US/questions/876323

I have entered a bug here where Firefox freezes every several minutes if you try to click a bookmark.

I tried the Places Maintenance add-on, and Firefox (7.01) continues to hang with NOT RESPONDING about every 5 minutes or so.

Helped to solve my issues too. In my case the intervale between hangs was 2 minutes. Now it seems to be solved. Thank You very much!

The plugin worked like a charm. Firefox is completely stable on this machine now.
Grazie Mille!

Hey, up there, be aware that this is not a fix for all the evilness in the world, if the add-on does not fix your problems, it’s better you contact support at http://support.mozilla.org/ to figure out the reason.
I want to also confirm Firefox 8 will contain a fix for this, I will blogpost when the fix is available in beta (likely next week).

Every 9 minutes — that sounds exactly right. Thanks for this!

That helped alot. Thanks! :)

Thanks! – Firefox 7 is now stable on WinXP SP3, Athlon 2400 – The Tool is working with immediate effect, – Vielen Dank !

This has been driving me nuts…and driving me to use Safari! I was still having freezes after updating to FF8, but everything seems to be dandy now after running the plugin. Thanks for staying on top of this!

Your add-on worked for me. Thank you so much.

FF7 freezing periodicaly. Change to default from Noia theme and for the last hour is working fine. thanks to all above. cheers.

“Go to about:addons and open the add-on Options dialog”

Where the heck is the “add-on Options dialog”

Get Add-ons
Extensions
Appearance
Plugins.

No options..

@Brian in the add-ons manager, check the add-on entry in the extensions list, each add-on may have an Options button.

Fixed it for me. FF was getting close to being unusable, now it’s working just fine again.

firefox started acting up early this week. i did this “workaround” yesterday. last night, it went back to freezing again. this morning it freezes about every three to four minutes. thanks for all the fish.

@mr.joe You can try using the current Firefox 8 beta. If it still hangs, you are probably hitting a different bug and it’s worth to contact support.

thank you
Thank You

FF on 64bit Win7 and I was just about to give up on FF until this fixed my problem.

Thank You

Awesome! Worked like a charm. I ran through all the maintenance tasks just to make sure. Been 3 hrs and haven’t had one freeze yet.

This was driving me up the wall. Been using this fix for weeks now and it’s completely solved the problem.

Thanks!!
It worked without a problem!

Thank you very much, this issue drove me crazy and now it seems to be fixed after doing a complete maintenance with your wonderful Add-On.

Both thumbs up! :)

Fix didn’t work. Had high hopes since pages loaded quicker just after fix, but got another freeze within 10 minutes. PLEASE fix this!!!!!

I have the same situation as G_Hz does. Apart from FF randomly freezing every now and then, the first time in each browsing session I want to download any kind of file, FF freezes. I am running Windows 7 ×64.

Freeze on download may likely be caused by Antivirus software, check yours.

Alas this didn’t work for me. Even trying to install this add on was a nightmare because Firefox just kept freezing every time I clicked my mouse on anything.However after prevailing for hours I did managed to get it installed only to find it made no difference.

I tried it on PC’s using both XP and Vista to no avail, looks like I’ll be sticking with Chrome for now until this bug is fixed, if it ever is:(

Massive fail Firefox- so very disappointing.

Can’t find where to report error regarding Firefox Bookmarks problem you commented on above. When I go to that part of their website, there is a message that the “article is no longer maintained.”

This did not work for me. Firefox 7.0.1 still freezes periodically about every 10-15 mins. Very annoying, let me know if there is some other solution, thanks.

The freeze is consistent every 15 mins. 20 seconds, and it peaks for about 20 seconds, then there is a 10 second rest, and it is followed by a second peak at the same intensity, clipping the envelope at full cpu. However, reducing the bookmarks to maybe a third of the volume changes the intensity of both peaks to a rounded top, and it almost completely eliminates the second peak. If I delete all the bookmarks, the problem disappears. Plug-ins includes Flash 11.0.1.152, but disabling it and even de-installing did not stop the freeze-up. Had a couple of add-ons that did not affect anything either way —- NoScript 2.1.8 and DownloadHelper 4.9.6. Windows XP, Core-2 Duo, laptop.

@ Marko :

The problem of freezing when downloading or uploading it probably comes from the Windows Explorer Seven. For it is when you choose the download location or the location where the image is to host the bug this product.

For me it is an incompatibility between Firefox and Explorer Windows Seven 64bit

sorry to pollute topic

I had the same problem with 7.0.1 your addon solved it (THANKS!)

Now i installed the update to 8.0 and it CRASHES EVERYTIME i go to
open the BOOKMARKS….

oh myyyy is a nightmareeee….

Today I have installed Firefox 8 and it keeps freezing up on my freshly installed Windows 7 64-bit. Many year was firefox my favorite browser, but I’m considering to say good bye.

Thank you for support all and you help for the users on the world.

Thank you to Mozilla Org. and users.

I updated into Firefox 8.0. It worked fine. The problem has gone.

I have FF8 the fix is basically not there & it still hangs like crazy. When I 1st start up it will NOT connect (despite other browsers doing so at the time) and will only work if I close it then reopen it.

Been a problem with 6 7 and now 8.

Wish that had been fixed, but I’ve been told unless millions of people have the problem then it does not exist.

I have the problem when using Facebook. I upgraded to Ver. 8.0, but the problem still happens :((( (Win XP Home edition)

suke, thanks for that update on FF 8.0 now not hanging anymore, but question, have you tried opening the Bookmarks, does it hang or crash upon that execution or while at it?

Please let us know, if it does, then FF has another problem….if not, good….. For me, I think is the incompatibility from one version to another of the BookMarks toolbar (ie: from say FF 3.0 to 5 & later)…….Let us know your feedbacks, thx,

JC,

Great. I had this problem. I upgraded to firefox 8. Now it freezes and doesn’t get out of that state. I’m stuck with chrome now…

The freezing problem still persists and after 5 years I’m considering migration to chrome. it’s losing market share…

The add-on seemingly it does many jobs at once, if you select “all”.

Do we need it anymore? I use Nightly 11, is it any useful to me? Do I have to do it from time to time or Fx currently does all these automatically?

Thank you!

The add-on is not “needed”, Firefox does that automatically. It is useful in certain situations to debug issues.

If you still see freezes in Firefox 8, then it’s not the bug that was fixed here, so please contact support at http://support.mozilla.org/ to figure out your case.

Annoying random freezings with FF 8.0 (currently the latest one). I’m looking around if someone else has the same problem, and it looks like yes… FF just freezes from time to time, not every 9 minutes, for about 30 seconds (application is not responding, white) then unfreezes.
I’m using Windows 7 ×64 SP1. Maybe it’s because of one of my few extensions : Firebug, All-in-one sidebar or Tab mix plus…

Aurora 10 (autoupdated each day) was freezing (100% one core usage) for 0.5 sec each 10-20 seconds. Restart usually helped for at least some time (mostly I restarted browser whenever wanted to view youtube, cause it was unwatchable otherwise), but then behaviour returned. This happened for several weeks.
Finally today I decided to look for a fix and tried Places Maintenance add-on you suggested. It helped, which contradicts with thing you said (it’s not needed with Firefox version > 8).
Its kinda sad I fixed it, cause it probably was a good idea to report it to developers somehow (I’m just not sure how, since firefox provides no about:threads similar to about:memory ;)

Thank you, my freezings were resolved by this plug in.
