Firefox very slow while Chrome is fast

Hi all

Spin LMDE 2, totally updated and using Firefox 50.0.2 Firefox is really very slow for some time now - it is so slow to start, slow to scroll a page even with one tab open and takes a minute to type a full word. I tried to start Firefox in safe mode, completely deleting my user profile and start fresh, use "apt - get remove - purge" and then reinstalling firefox... and still stupidly slow. Chrome is fast, quick start, can run 20 + tabs without a slowdown in performance, no problem at all.

And my laptop is not in rest - it is 3 years old, has a processor i7, 8 GB of RAM and a Quadro video card. I have also run 2 LMDE and all apps from a 256 GB SSD card. The directory is on a 500 GB SATA hard drive, however. So I expect you to improve the performance of Firefox, so there must be something wrong - I would really appreciate if someone could give me some guidance as to what could be the problem please?

Hello

Some Firefox problems can be solved by performing a clean reinstall. This means that you delete your Firefox program files, and then reinstall Firefox. This process does not delete your Firefox profile (such as bookmarks and passwords) data, since this information is stored in a different location.

To do a clean reinstall of Firefox, follow these steps: Note: you can print these steps or consult them in another browser.

  1. Download the latest version of Firefox from mozilla.org office (or choose the download for your operating system and language on this page) and save the file to install it on your computer.
  2. Once the download is complete, close all Firefox Windows (or open the Firefox menu and click on the button close ).
  3. Remove the Firefox installation folder, which is located in one of these locations, by default:
    • Windows:

      • C:\Program Files\Mozilla Firefox
      • C:\Program Files (x 86) \Mozilla Firefox
    • Mac: Delete Firefox in the Applications folder.
    • Linux: If you have installed Firefox with the distribution-based package manager, you must use the same way to uninstall: see Install Firefox on Linux. If you have downloaded and installed the binary package from the Firefox download page, simply remove the folder firefox in your home directory.
  4. Now, go ahead and reinstall Firefox:
    1. Double-click on the downloaded Setup file and go through the steps in the installation wizard.
    2. Once the wizard is completed, click to open Firefox directly after clicking the Finish button.

More information on the resettlement of Firefox can be found here.

WARNING: Do not use an uninstaller to third parties as part of this process. This could permanently delete your Firefox profile data, including but not limited to, extensions, cache, cookies, bookmarks, personal settings and passwords saved. They can be retrieved easily unless they have been backed up on an external device! See back up and restore the information contained in the profiles of Firefox.

Please report to say if this helped you!

Thank you.

  • Firefox very slow, slow and unresponsive on Windows 8.1

    Basically, everything is very slow and each action takes a long time to complete - tabs, switching takes about half a second to a full second (5 seconds if there is another tab currently loading / refreshing), by clicking the Center button of the mouse takes more time, about half a second to a second for the exactly scrolling of arrows is displayed same thing with regularly by clicking on the scroll on the right, Firefox bar pretty much freezes for about a full second before reacting to the click.

    I tried to run Firefox with addons disabled, which did not help, which I did not know that he don't would be not since this problem started before I even had the addons - pretty good the second, I installed Firefox.
    I have Firefox running on an SSD card and a new installation of Windows 8.1. I tried the two Aurora and nightly (currently using every night), both are just as slow.

    I have not tried to reset, because once again, the question was already there during my first installation of Firefox.

    Figured out what the problem is - it is a software of DisplayFusion I use to support multiple monitors which is causing the problem. I'll just get an alternative until (if ever) the question ceases to exist.

    Thanks for the help.

  • Charge of menus (right click, bookmark, etc.) of Firefox VERY slow

    System information:
    Windows 7 Home Premium, 64-bit.
    Intel Core 2 Duo 2.53 GHz
    6 GB memory
    Intel SSD 320 series

    Gradually, for a few years, FireFox has got slower and slower for me. Not really, navigation, but the menus. It takes place in about 3 seconds to load the right click menu, or the "FireFox" menu at the top left, or book marks.

    History, Cache, Cookies have been deleted. All extensions and plugins disabled. If I disable all the startup home pages.
    It still responds

    When I reinstalled Windows ~ 2 months when I arrived the SSD (it was a clean install) is behavior immediately during installation.

    It makes me crazy, and I'm about to give up FireFox!

    Anyone know what is happening and how to fix it?

    Try turning off hardware acceleration.

    • Tools > Options > advanced > General > Browsing: "use hardware acceleration when available.

    If disable hardware acceleration works then check if there is an update available for your graphics display driver.

    Create a new profile as a test to see if your profile is the source of the problems.

    See "basic troubleshooting: a new profile:

    There may be extensions and plugins installed by default in a new profile, so check that in "tools > Modules > Extensions & Plugins" in case there are still problems.

    If this new profile works then you can transfer files from the old profile to the new profile, but make sure not to copy corrupted files.

  • Client performance is very slow

    On the part of the Oracle database and E-Business applications track, I installed the PA for the Oracle database and the extension of the PA of E - Biz.

    The location of the servers the PA Middleware and collector is in WE (Boston) , while the PA Client is installed on the local machines in India (New Delhi).

    The PA Client performance is very slow while we move from one screen to another.

    I know that it is clearly the bottleneck of bandwidth bandwidth/latency network, always looking for suggestions to mitigate.

    I think that the network latency is your problem here. The two recommendations that I have are:

    (1) use the web interface in the UI Foglight. This should perform better especially if you use a local FglAM to the collector and middleware.

    (2) use a terminal server server or virtual office in Boston to install thick client PA. This will give you the best user interface response times.

    Thank you

  • Firefox has become very slow. It takes a lot of time to load any website. I reinstalled FF but the fleeting problem.

    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.

    Check it out and let me know if it works: Refresh Firefox – reset the parameters and modules

  • Firefox is very slow when you use RDP

    Firefox is fast when you use Windows directly. But when you use RDP it is very slow. For example, empty new tab takes about 6 seconds to open. The RDP connection is fast and another response programs immediately (for example the same page navigation in IE is fast).
    What is the problem with Firefox?

    Could it be the graphics hardware acceleration?

    You will need to probably restart Firefox for it to take effect, so save any work first (e.g. you compose mail, documents online that you are editing, etc.). On the remote system:

    Orange Firefox button or classic menu Tools > Options > advanced

    In the mini ' General' tab, uncheck the box for "use hardware acceleration when available.

    Then restart Firefox. Does make a difference?

    If it is low volume in Firefox, you may need to increase the volume for Firefox under Windows. Please see that.

  • 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.
