Which Webpage is it?

The pop-up from Firefox does not specify which webpage is slowing down your browser. But you may use Firefox’s task manager to find out. Put the command address in the URL field to access the task manager.

Solution 1: Disable Adobe Flash Protected Mode

This solution is just for 32-bit systems, as this option is not available on 64-bit Windows browsers. But even Mozilla admits that it might cause frequent crashes and errors like this. That’s why you can disable it and see if it helps.

A little more complex solution is available for 64-bit Windows users.

  1. Double-click the Mozilla Firefox icon on the Desktop or search for it in the Start menu.
  2. Click on the menu button in the top right corner of the browser and select Add-Ons.
  3. Locate and select the Plugins option in the right pane of the screen to see the entire list of installed plugins. Click Options next to Shockwave Flash and uncheck “Enable Adobe Flash protected mode”.
  4. Restart your browser to see if the issue is resolved.

64-bit Windows users:

1. Try browsing to this place from My Computer or This PC in File Explorer:

C:\Windows\SysWOW64\Macromed\Flash

2. If you can’t see any of the directories in the process, it’s because your system has hidden files disabled.

3. Select the “Hidden items” checkbox in the Show/hide section of File Explorer’s “View” tab. File Explorer will now show hidden files until you alter them again.

4. Look for mms.cfg. Edit it by right-clicking it. You will need administrative rights to do so. When prompted, choose New >> Text File from the Flash folder. Save the file as “mms.cfg” and select All types.

5. In any case, edit the mms.cfg file and add the following line at the end:

ProtectedMode=0

6. Save and exit Notepad. This update will occur when the Flash plugin has been disabled, so close Firefox and wait a few minutes.

Solution 2: Clear Firefox’ Browsing Data

If a corrupt file got onto your computer via Firefox’s browser data, you should expect a performance hit. This can only be addressed by clearing the Firefox browsing data such as cookies, temporary files, etc.

  1. Double-click the Mozilla Firefox icon on the Desktop or search for it in the Start menu.
  2. Click on the library button (left of the menu) and select History >> Clear Recent History.
  3. You can choose from various choices. Select Everything from the dropdown list under Time range to clear.
  4. Click the arrow next to Details to discover what will be removed if you choose Clear history. Firefox’s history includes cookies, temporary data, and other items that Chrome does not.
  5. Before clicking on Clear Now:
  • Select at least Browsing & Download History, Cookies, Cache, and Active Logins.
  • Restart your browser.
  • See if the issue has been resolved.

Solution 3: Update your Graphics Card Driver

Even if you aren’t having trouble right now, updating drivers is essential because outdated drivers might cause issues. If you use your browser to view graphics-intensive websites, the video graphics card driver is to blame. Update the driver and see if the issue persists.

  1. Start, type Device Manager, and choose it from the results. Alternatively, you can use Windows Key + R to launch the Run dialogue box and type esc before clicking OK.
  2. Expand a category to find your device’s name, then right-click (or tap and hold) it and select Update Driver. Click on your graphics card in the Display adapters category and select Update Driver.
  3. Select Automatically update driver software and follow the on-screen directions to install.

If this doesn’t work, you can download the latest driver to the manufacturer’s website. They generally help you choose the correct driver for your system. The manufacturer’s website may also upload new drivers before Windows’ automatic search.

After that, you should always check your Firefox video settings as follows:

1. Double-click the Mozilla Firefox icon on the Desktop or search for it in the Start menu.

2. Please copy the following address or type it in the address bar. After finishing, click Enter:

about:preferences#privacy

3. Check if the option Prevent accessibility services from accessing your browser is checked in the Permissions section at the bottom of the window. If the checkmark is missing, add it.

4. Untick all settings under General >> Performance at the top of this window. Reduce the suggested size to 2, but not below. Adjust these settings until you’re happy.

Solution 4: YouTube Error

If this happens on YouTube, it may be due to their new, buggy design. It also uses a lot of resources, so going back to the old YouTube version may help.

  1. Double-click the Mozilla Firefox icon on the Desktop or search for it in the Start menu. Enter or copy the “youtube.com” address in the address bar.
  2. Then locate the profile image icon and click the downward pointing arrow.
  3. From the dropdown menu, select Restore Old Youtube. Answer Google’s questions about why you’re going back to the previous site, then see if YouTube still has the same issue.

Solution 5: Disable Two Settings in about::config

Several users reported success disabling these parameters in config. That’s why most tech sites now have the solution. Good luck and follow the rules.

1. Double-click the Mozilla Firefox icon on the Desktop or search for it in the Start menu.

2. Please copy the following address or type it in the address bar. After finishing, click Enter:

about:config

3. In the search bar at the top of the website, look for “dom.ipc.processHangMonitor” and “dom.ipc.reportProcessHangs”. Double-click on both entries to make them false.

4. Save changes and restart your browser to take effect. Check if the issue is resolved.
