For the past week I am having issues with Tabs repeatedly Crashing..getting the "gah, the tab has crashed" notification. Here are a few reported bp-9c346be9-7d6e-4734-846e-63fb30170810 8/10/2017 10:21 AM bp-e4b0f215-7f10-4470-9bd9-e20dc1170809 8/9/2017 3:10 PM bp-17443c68-c3a6-4fb8-96be-456791170809 8/9/2017 1:22 PM bp-f071b601-3e29-47d2-9261-0ed651170809 8/9/2017 12:24 PM

Chosen solution

There is one crash report that is a problem with the Shockwave Flash plugin.

  • Firefox 55.0 Crash Report [@ F1398665248_____________________________ ]

You can check for issues caused by plugins.

  • set plugins to "Ask to Activate" on the about:addons page ("3-bar" menu button or Tools -> Add-ons -> Plugins)
  • plugins are not affected by Firefox Safe Mode

You can try to disable hardware acceleration in Firefox.

  • Options/Preferences -> Advanced -> General -> Browsing: "Use hardware acceleration when available"

You need to close and restart Firefox after toggling this setting.

You can check if there is an update for your graphics display driver and check for hardware acceleration related issues.


You can create a new profile to test if your current profile is causing the problem. You may have to disable hardware acceleration in the new profile.

See "Creating a profile":

If the new profile works then you can transfer files from a previously used profile to the new profile, but be cautious not to copy corrupted files to avoid carrying over problems.

Sometimes a problem with Firefox may be a result of malware installed on your computer, that you may not be aware of.

You can try these free programs to scan for malware, which work with your existing antivirus software:

Microsoft Security Essentials is a good permanent antivirus for Windows 7/Vista if you don't already have one. Windows 8/10 have antivirus protection built-in.

Further information can be found in the Troubleshoot Firefox issues caused by malware article.

Can you post new crash report to see if this are the same crashes or something different?

If you have submitted crash reports then please post the IDs of one or more recent crash reports that start with "bp-".

  • bp-xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx

You can find the report ID of recent crash reports "on the "Help -> Troubleshooting Information" (about:support) page".

  • click the "All Crash Reports" button on this page to open the about:crashes page and see all crash reports.

Alternatively you can open about:crashes via the location/address bar.
