Firefox is slow to open

• Firefox extremely slow, not open web sites correctly. Especially in the last 24 hours.

  In the last 24 hours (from April 27), FF4.0 became incredibly slow, unable to open many sites completely or correctly (i.e., BBC NEWS, Twitter) or the opening of sites but not able to use fully (i.e. opens hotmail but did not open any new messages). This is not the case with Chrome or I.e. browsers seems to be specific FF.

  This is probably due to the WangWang (ww-plugin), you have installed. Disable it in Tools | Add ons | Plugins and then see troubleshooting issues with plugins like Flash or Java to solve problems of Firefox for instructions on how to uninstall it.

  Please also go to the Plugins check page and see if the version of Flash you have installed currently needs to be updated or not. I don't recognize the version you have installed.

  If the problem persists after the above troubleshooting steps, please try running Firefox in questions to troubleshoot Firefox in Safe Mode. If it works properly in this configuration, then one of your modules is the culprit.

• new updates of windows, firefox slow to open

  My computer installed two new windows updates... KB3021917 and KB3006137. Since then, Mozilla Firefox is slow to open. It takes at least 5 minutes. However, once the internet is in place, it works fine. It's just the process of the opening of the internet. Help, please.

  Hello

  I did some research and found out that it should be good if you ignore these two updates.

  KB3021917 - unless you are testing 10 Windows, you don't really have this update.

  KB3006137 - this update is pretty useless too, it changes the currency symbol of the Lithuania. https://support.Microsoft.com/kb/3006137?WA=wsignin1.0

  I hope this helps!

• 7 Firefox is very slow to opening pages as compared Web o firefox6

  Compared to firefox6, this version, ff ver # 7.0.1 is very slow to open Web pages. It takes a long time to display the Web page. I tried to disable add ons and did everything I could, but it seems that there is a no solution.

  One possible cause is security software (firewall) that blocks or limits Firefox or plugin-container process without informing you, possibly after the detection of changes (update) for the Firefox program.

  Delete all rules for Firefox in the list of permissions in the firewall and leave your firewall again ask permission to get full unlimited access to the internet for Firefox and the plugin-container and the update process.

  You may need to use questions Troubleshoot Firefox in Safe Mode (click on "Safe Mode" and reading) to locate the problem. Firefox Safe mode is a diagnostic mode that disables Extensions and some other features of Firefox.

When you enter Safe Mode, do not check all the items in the window, just click "continue mode without failure." A test to see if the problem you are experiencing is fixed.

• Firefox starts slow, but works well in safe mode with all the running addons - why?

  Then... all of a sudden my Firefox (v. 38.0.1) is really laggy, with slow-to-respond buttons, scrolling etc. So I manually disable all addons, but nothing helped. Then I try safe mode and it works very well. Large. So I turn on my addons again one by one, until they are all allowed and it still works fine. My conclusion: it isn't the addons. What is what is the cause? I have updated all my addons and just Silverlight, Flash, Google updater, Shockwave and some others.
  One solution would be for this mode - Safe with addons running - being my default start mode, but I can't work out how to do it. Is no huge problem because I can make Firefox work perfectly, but it's a little bit of your time.
  Any ideas?

  Hi RufusWalker, please see if Firefox is slow after upgrading to Firefox 38 covers and solves your problem.

• Firefox is slow

  I was running firefox 37.0.2 with kaspersky antivirus 2013 and zonealarm pro and had no problems. After that I updated to kaspersky antivirus 2015. I tried to start firefox and it took a long time to load up. When I try to search something on google, it takes a long time to load a page. So I tried to refresh and it didn't work so I tried to upgrade to the latest version of 38.0.1, also did not work. So ive installed kaspersky anti-virus 2013 again and again, firefox is slow. Ive tried refresh characteristic, clean the cache, clear the acceleration hardware and even went to firefox 34. None of them worked.
  When I run firefox with Pei firefox.exe and select a profile, firefox works fine, but when I launch it from bar tasks, it is very slow to start to the top and loading pages. And when I try to delete a profile, it ask me to delete the files. If I try to do, it freezes as well. So I can only manually delete new profiles.

  Thanks for the help. I removed kaspersky antivirus and zonealarm firewall pro and installed kaspersky internet security and it works well. I think the last patch of kaspersky antivirus 2013 (patch L) is causing a conflict with zonealarm pro.

• Firefox crashes when you open new tab

  Crash-ID: bp-681f1751-fc5b-4f14-a30b-f93ed2150407

  I tried:
  Clean install (with the removal of C:prog... \Mozilla)
  Uninstallation and removal of extensions
  Firefox restarted in safe mode without addons/extensions.
  Uninstalling/updating flash/adobe

  Can I start firefox, but when I press on the "+" to open a new tab Firefox closes and the ' Mozilla Crash report ' window opens.
  It seems that firefox it self can open a tab. For example, when I do a new installation, Firefox opens with 2 tabs.

  But when I want to open one that it breaks down and Firefox stops. Its really weird because I've never run this kind of problem before and I don't remember installing anything new until this problem appeared.

  What is the setting of the new tab page?

  You can check the browser.newtab.url pref on the topic: config page.
  You can open the topic: config page via the address bar.
  You can accept the warning and click on "I'll be careful" to continue.

• Firefox crashes after I open a new tab

  Hello
  My Firefox crashes whenever I open a new tab (empty). The same phenomenon occurs in safe mode. Here are links to some of the latest crash reports:

  Thank you.

  You might try using a new profile. It might be hard to go at least a whole day without your pets addons, bookmarks, and history... the bookmarks are fairly easy to copy.

  Create a new Firefox profile

  This is in addition and does not replace your existing settings.

  A new profile will be your plugins installed by system (for example, Flash) and extensions (e.g., security suite toolbars), but no themes, other extensions or other customizations. It should also come with fresh data bases of completely fresh settings and a cache folder.

  Out of Firefox and start in the profile using Start Manager > Search box (or run) - type or paste the following and press ENTER:

  firefox.exe -P
  

  Do not delete anything here.

  Any time want to switch profiles, exit Firefox and return to this dialog box.

  Click on the button to create a profile, assign a name like April8 and ignore the possibility of changing the location of the folder. Then launch Firefox in the new profile that you have created.

  It might take some time to determine if the new profile works better than the old. If you want to import your Favorites from your regular profile in the meantime, here's how:

  You can use the dialog library (Ctrl + Shift + b or "Show all bookmarks") to access the restore feature. The trick is to know where to find your bookmark backups in your regular profile. After clicking on file... you can paste this into the space of file name and press ENTER to drill down to your profile folders:

  %APPDATA%\Mozilla\Firefox\Profiles
  

  The semi-randomly-named folder that has your last backup is generally the one that ends with "failure". Click in that one, and then in the folder bookmarkbackups . Here you can choose the most recently updated to restore file.

  Important: restoring a backup bookmark clears all bookmarks currently in your current Firefox profile and replaces it with the contents of the backup file.

  In my view, it is also reasonable to install AdBlock Plus, Restorer of classic theme, and Status4Evar, like those who, by themselves, are not likely to be at the origin of this apparently rare problem. But I wouldn't add all your extensions to the time in the new profile, and if many show extensions system installed, you can disable those you don't actually use.
