Hi,

You're using IceWeasel 24.4.0 which is what Firefox ESR is based off of. ESR is only used for system administrators running a large network. It isn't "officially" supported here but some of this still take it on. Additionally, if you have any other issues with IceWeasel, you should find a 3rd party that supports troubleshooting for it.

Have you recently installed any new add-ons?
Can you try to access Firefox in Safe Mode to see if the problem still exists and/or if it opens? You can follow the below instructions to start it in that mode.

• Go to Help > Restart with add-ons disabled
• When Firefox closes and re-opens, select Start in Safe Mode

If Firefox works properly, then it's most likely one of your extensions misbehaving. You can enable your add-ons back on by one until you find the conflicting extension.

The only issue I have with this is that the problem isn't readily reproducable, it happens every so often, I cannot predict when it will happen.

Hello,

The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information.
Note: This will cause you to lose any Extensions and some Preferences.

• Open websites will not be saved in Firefox versions lower than 25.

To Reset Firefox do the following:

1. Go to Firefox > Help > Troubleshooting Information.
2. Click the "Reset Firefox" button.
3. Firefox will close and reset. After Firefox is done, it will show a window with the information that is imported. Click Finish.
4. Firefox will open with all factory defaults applied.

Further information can be found in the Refresh Firefox - reset add-ons and settings article.
