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.

  • 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.

    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.

  • 24 of Firefox with vista to date fails to display icons on the new Yahoo Mail and other web sites — especially icons such as facebook, twitter WHY?

    Web sites like murraystivoli.com that display the facebook and twitter icons and in particular the new Yahoo Mail interface fail to display the icons. I see only a small rectangle. On Yahoo Mail, there are a few inside but instead it should be the display arrows, images of envelopes or as medium icons or 'send '. The new interface is useless without correct icon translation - can not see the arrows for 'reply' 'reply to all '. It works on Internet Explore on Vista; It works on Firefox on Windows XP (it's the way back level) then why do we see this problem with Vista and Firefox update (we 24.0 but saw problems on websites that I don't care that much about other levels of Firefox also.)

    Help, please!

    Same problem here... I have no icons or tick boxes at all in Yahoo mail and it affects a good few other sites too, just small square boxes with numbers inside. It's really annoying!

    Here's what it looks like (you may need to zoom in a bit)...

  • Very slow internet connection on Win 7 on SSD, but works very well with the OS on the HARD disk and the mode safe on SSD

    Original title: network very slow connection on the current installation of Windows?

    So my situation is that I have two disks (SSD and HDD) who both have a Windows installation.

    Because this SSD is an I got free and is in used condition, I left my copy of Windows 7 intact on my mechanical failure of the SSD drive.

    Now the question is, my internet connection is very, very poor, unless I run in safe mode, or the installation on my mechanical drive.

    I use a wired connection, and our connection at home is limited to 120/10 mbit/s, while I have 5/10 at the most.

    I tried to replace the LAN drivers of my motherboard (MSI FM2-A85XA-G43) using both the driver disc that was bundled with my motherboard, Device Manager and the official site of MSI, I also checked my entire system using Malwarebytes, which detected 7 threats and were abducted, nothing helps.

    I also tried the DNS which did nothing either of hot flashes. Now notice what computer of my brother is also connected and works well.

    Now as I type this, I discovered that my speed has suddenly got stable again out of the blue, but I'm skeptical it will remain, so I still want to ask what is / was going on here.

    Thank you for your time.

    Sorry for the late response here, I've been very busy with the developments in the last days and completely focused on it.

    More than a week has passed since the problem disappeared as if by magic, and so far I don't see the signs of what is going on again.

    I think that the problem has passed away now, but if it arises again I will probably update this.

    Thanks for all the suggestions and your time in this issue.

    recently purchased a samsung NX30 camera which came with lightroom 5, after several hours of searching on Google I got it setup properly with the right camera raw to be able to access my raw images. I found that my old laptop is very slow during the processing of hundreds of images that I usually take on a weekly basis.  I bought a new faster laptop, but when I looked for the cd with the software of series and I couldn't find in the mess of Christmas.  I downloaded a trial version of lightroom and got, it works on my new laptop. Is there a way to access the serial number of my version already installed and insert it in the version of track to make it work for me?

    Myron

    If you take the time to register to your original with Adobe installation (which most people do not), you can log in to your Adobe account and get the serial number. If you use a Windows computer and still have access to the old computer where Lightroom is installed, you can do the following:

    1. in the window folder options, make sure that you are able to see hidden folders.

    2. go to the C:\ProgramData\Adobe\Lightroom folder.

    3. use Notepad to open the file, Lightroom 5.0 Registration.lrreg

    You will be able to retrieve your serial number of this file.

  • Why most of the tabs open empty with the label "New tab" and "topic: vacuum ' in the address line to the restart of Firefox since installing Firefox 28?"

    I have a system dual-bootable Windows Vista SP2 and Firefox updated to 28 on both systems. Since the update of the tabs more reopen empty with the label "New tab" and "topic: vacuum" in the address line of Firefox is restarted. The tabs that open correctly seem to be those who in fact, I was at the session of prefious. I can recover the missing tabs using the Session Manager to pick up a previous session, but of course it does not pick up the tabs open in future sessions. It seems that the tabs that I go to the session recovered are saved correctly, as indicated above, but which are not revisited in the context of the use of the session retrieved will drop the URL next time that I open Firefox it again.

    jdgale:

    I don't have the time to do it. However, 29 is just around the corner and we will put in the channel of exit 29, then hope that the issue is not you.

    P.S. I had originally chosen your last answer as the solution that you have migrated more to 29 but it seems that you have taken off. I'll be marking your last answer as the solution so that we can get out of the queue.

    Firefox is very slow to respond when you open and almost always unresponsive altogether, refusing even to respond to Manager task "End program" command. The "not responding" error message is also over browsing online. Several attempts must be made to get online. A loss of stability seems to be endemic at the present time.
