Hello,

To find the correct solution to your problem, we need some more non-personal information from you. Please do the following:

  1. Use ONE of these methods to open the Firefox Troubleshooting Information page:
    • Click the menu button New Fx Menu, click on help Help-29 and select Troubleshooting Information.
    • Type about:support into the Firefox address bar and press the enter key.
  2. At the top of the Troubleshooting Information page that comes up, you should see a button that says "Copy text to clipboard". Click it.
  3. Now, go back to your forum post, right-click in the reply box and select Paste from the context menu (or else click inside the reply box and press the Ctrl+V keys) to paste the information you copied into the forum post.
    • Due to a character limit on forum replies, only part of the data may be pasted. You can copy the data to a text file and post an additional reply to add missing information.

Note: The Troubleshooting Information page does not contain personal data, except for the full path to your profile folder. When you use one of the "Copy to clipboard" buttons, the profile path is not copied. Use other tools and methods at your own risk.

If you need further information about the Troubleshooting information page, please read the article Use the Troubleshooting Information page to help fix Firefox issues.

Thanks in advance for your help!

Hi FFus3r thanks for quick reply. I posted Troubleshooting Information part 1 and part 2 in next post. By the way "Quick fixes if your Firefox slows down" didn't help me, only clear installation (like I mentioned before) Part1:

Hello,

Try disabling graphics hardware acceleration in Firefox. Since this feature was added to Firefox it has gradually improved but there are still a few glitches.

You will need to restart Firefox for this to take effect so save all work first (e.g., mail you are composing, online documents you're editing, etc.,) and then perform these steps:

In Firefox 54 and below:

  1. Click the menu button New Fx Menu and select Options (Windows) or Preferences (Mac, Linux).
  2. Select the Advanced panel and the General tab.
  3. Uncheck Use hardware acceleration when available.
  4. Close Firefox completely and then restart Firefox to see if the problem persists.

In Firefox 55 and above:

  1. Click the menu button New Fx Menu and select Options (Windows) or Preferences (Mac, Linux).
  2. Select the General panel.
  3. Under Performance, uncheck Use recommended performance settings. Additional settings will be displayed.
    Fx55Performance-disableHWA
  4. Uncheck Use hardware acceleration when available.
  5. Close Firefox completely and then restart Firefox to see if the problem persists.

Did this fix your problems? Please report back to us!

If the problem is resolved, you should check for updates for your graphics driver by following the steps mentioned in these Knowledge base articles:

Thank you.

What security software do you have?

It is possible that your firewall or other security software blocks or restricts Firefox without informing you, possibly after detecting changes (update) to the Firefox application. Remove all rules for Firefox from the permissions list in the firewall and let your firewall ask again for permission to get full, unrestricted, access for Firefox and the plugin-container process and the updater process.
