Typing becomes very slow in Firefox 3.6.11 in Mode safe mode with all extensions and plugins disabled.

When I first start Firefox, all right. And everything is fine as long as I type in the text boxes on any web page. I can type in the address bar or search throughout the day with no problems.

But, for example, just by typing in the edit box to ask this question on this site will result in the problem after I typed more say 150 characters. After this strike ANYWHERE in Firefox will be very slow, even the address bar or the search bar. It doesn't seem to matter what site use to type in the text. Cause the problem to occur after typing in enough strikes.

Navigation & mouse clicking remains fast - it is only typing seems to be affected. In order to recover, I have to restart Firefox.

If I look at the use of the UC Firefox.exe in Process Explorer, I see that once the problem occurs, the CPU usage starts whenever I type a key fortification. Indeed Firefox maxes one of my two hearts so the cpu is at 50%! He goes down to 0% again once I stop typing.

As mentioned in the subject, it is in Mode safe mode with all extensions & plugins disabled. I'm running on Windows XP SP3 with an old AMD Athlon 64 X 2 Dual Core Processor 3800 + (1.81 Ghz) with 2.00 GB of RAM.

I think it started to happen with Firefox 3.6 significantly (it's amazing how much time I can navigate without having to type), but it sometimes occurred with previous versions. Now he is annoyingly repeatable.

I have to use '-no - Pei ForTyping distance "to start a separate session of Firefox that I use just to type in the text boxes, so I can restart at will. I also compose messages in an external editor and simply paste in Firefox to avoid typing as much as possible.

This may be a problem with session restore. Firefox stores session data every 10 seconds to make it possible to restore a session crashed.

It may be a problem with the sessionstore.js file in the profile folder

Delete the sessionstore.js and sessionstore.bak and all files files sessionstore-# .js with a number in the left part of the name as sessionstore - 1.js.

    Using Dell PC/Windows XP. I love how Firefox is running in SafeMode so inflated as usual. I would like to be able to start Firefox in safe mode, without having to always restart Firefox to get in safe mode. Anyway to do it? Thank you very much!!!

    Ok. Thank you guys created and a new profile and restarted and all kind of memory freed, but of course Firefox is practically naked, so is expected.
    Checked the plugins and extensions, no major problems that are not there, I could see. I have a Gig of RAM installed around a little more, do not think I can add as many more on my old Dell PC of 2005. So I'll just switch to Firefox Safe mode when memory begins to be tight.

    Firefox has become very slow. It takes a lot of time to load any website. I reinstalled FF but the rest of the problem.
    As a test, I downloaded Chrome and it is much faster.
    But I love FF and would be very happy if you can help me solve this problem.

    Hi Reos,

    When you reinstall Firefox it always uses your old profile with all the old things that you had. That said, you're lucky, there is a new feature that lets you "Reset" of Firefox. This will remove some of the pieces that might cause problems while it keeps your bookmarks and other important things safe.

    • Tried other devices: I tried the connectivity to other devices (iphone & ipad) and found no problem. Speedtest app appears 32mbps to the low and 5 Mbps + constantly.

  • HP DV3 become very slow where implementation failure

    HP DV3-2105ee

    Windows 7 ultimate 32 bit.

    Since I bought this laptop new each time failed when his laptop battery performance becomes very slow start of braking, power option is to select "Balanced" if I select 'Power saver' he not become slow when running on battery power, but often it becomes slow with any program running.

    In my country Bangladesh there are break after every hour of power.

    How can I solve this problem?

    This sounds like it may be related to a power management.  Looks like it's to reduce the performance of the material to save batteries.  This is a normal behavior with laptops, but it can become a nuisance if someone does not create a power plan that does not take account of this.

    Go to start, search for food options and open this result.

    Click on Show additional plans.  There should be a plan for high performance.  This plan will be favourable performance during the conservation of battery, so your battery charge may not last as long.

    Activate the power plan.

    The problem is still happening?

  • Auto flash drive has appeared on my screen. Since I can't play video, and my system has become very slow. I have Mac OS Lion 10.7.5 and software is up to date. Before that everything worked beautifully. Can you please provide a link then

    Dear Adobe.

    Yesterday, I installed the latest version of Flash Player that car appeared on my screen. Since I can't play video, and my system has become very slow. I have Mac OS Lion 10.7.5 and software is up to date. Before that everything worked beautifully. Can you please provide a link so I can uninstall the latest version only. Thank you. Stephen Kress. Melbourne. Australia

    When you run the uninstall program, it allows to uninstall all versions of Flash Player.

    If you want to revert to an old version after that, get it from http://helpx.adobe.com/flash-player/kb/archived-flash-player-versions.html

  • Firefox is faster on the safe mode. Even when I disable all extensions and plug-ins, it does still work on normal mode. What should I do?

    I already tried to uninstall e install again, but rest the problema. When I use safe mode, firefox works correctly. I tried to remove all extensions and plug-ins, but the problem persists.

  • Firefox becomes very slow with the all new Yahoo Mail

    Problems with the all-new Yahoo! Mail version: everything worked very well, but since the two latest updates of Firefox I started to notice that Yahoo was consuming a lot of CPU (it varies from 35% to 40% and is on the top list of programs CPU consumption) and the browsing experience is not so pleasant - slow. If I quit Firefox and reopen it, becomes faster, but after about 30 min slow / high CPU consumption again. Then I had to go back to the classic version of Yahoo Mail and everything works fine and consumed less CPU. Did I live it? Is it a question of Yahoo Mail? Is there a solution? (Macbook Pro early 2011 / Mac OS X 10.7.4 / Firefox 12.0) Thank you!

    Try to start Firefox in safe mode. This mode disables all extensions, customizations, hardware acceleration, etc., temporarily for the diagnosis and troubleshooting. If Firefox works fine in Safe Mode, then it is probably a problem with the add-on. Restart Firefox in normal mode, and then type "subject: addons" (without the quotes) in the address bar. Disable your extensions, restart Firefox between each one, until you find the troublemaker.

  • I downloaded 8.1 on my iPad a few months ago and it has become very slow especially in the e-mail program and glitch

    I have an iPad mini version 9.02. a few months ago, I downloaded the latest operating system from Apple 8.1 and my iPad became very slow and glitchy especially in the e-mail software... What can I do?  Now it asks me to upgrade to iOS 9.1 and I fear that it will be even worse.

    Sorry - but what do you mean you have an iPad Mini version 9.02? What are your reference when citing 9.02?

    At this point, your best bet is to keep the device up to date. The latest version of iOS is 9.2. It's what you could be upgraded to.

  • Microsoft Update maintains the search forever and pc becomes very slow

    Hi all

    Last week did a cleaning installation (windows 7) on my old laptop.

    (the material is not good enough for an update for windows 10)

    At the beginning everything was fine and some updates have been installed.

    However, after the installation of "Windows 7 Service Pack 1 for x 64 systems (KB976932)" the trial was kept updated search forever and the laptop became also very slow.

    While windows searches for updates, the process "svchost.exe" develops very quickly in the memory usage and fills after a few minutes the total RAM.

    I tried various corrections (see for example the you link below), but none of the solutions worked for me: (.)

    http://superuser.com/questions/951960/Windows-7-SP1-Windows-Update-stuck-checking-for-updates

    For now I have disabled the update, but this isn't a permanent solution.

    I hope that any body could help me solve this problem.

    Thanks in advance!

    P.S. I also added a picture of the history of the update below.

  • WiFi constantly fall, becomes very slow or can not find the network

    You just bought a new Sony Vaio with Windows 8 and the wifi keeps deleting, becomes extremely slow or can't find my home network. I know that it is not the router because my other two laptops work fine and have full wifi signal (1 running Windows 7, the other is Windows Vista). I tried using the troubleshooting and it cannot solve the problem (if it is said) and claims that my ethernet cable or cable router is not connected (does not solve anything because my problem is wifi, not on the cable).

    Perform a search on Google, it seems that it is a major problem with Windows 8.  Anyone have any ideas on how to solve this problem, before returning the laptop? (the question of the internet makes the laptop almost unusable because most of my things are on the cloud)
