Since about a week ago my girlfriend's Firefox 19.0.2 started to crash with low memory message. She's using a laptop with 3 gig of memory and Windows 7 32. Her add-ons are adblock, WeatherBug and some spellcheckers. I reinstalled her browser and also installed Memory Fox plugin. It didn't help. Crashes occur once in one or two days after several hours of browsing.

I asked her to save the "about:memory" page when the low memory message appears. These are the first lines:

1,347.68 MB (100.0%) -- explicit

├──1,007.93 MB (74.79%) -- images

│ ├──1,007.71 MB (74.77%) -- content

│ │ ├──1,007.65 MB (74.77%) -- used

│ │ │ ├────601.40 MB (44.62%) ── raw

│ │ │ ├────361.11 MB (26.79%) ── uncompressed-nonheap

│ │ │ └─────45.14 MB (03.35%) ── uncompressed-heap

│ │ └──────0.06 MB (00.00%) ++ unused

│ └──────0.22 MB (00.02%) ++ chrome


She also sent me the page just after she started Firefox (with her pinned tabs) and there are no such memory figures.

Unfortunately I can't be more specific. She can't say if she changed something recently and she's also unable to cause it to happen when I am there.

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, Open websites, and some Preferences.

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.
