Firefox Memory Leak Problems -- Refresh Firefox

So I've been experiencing major memory leaks with Firefox since version 36. Using around 1.7GB of memory and very slow sometimes for certain pages. Google searches revealed that yes, there was a major leak. It was supposed to be fixed.

Now in late version 37, the problem still persisted for me.

(WARNING: Always backup your firefox profile before testing other version!)

I tested using their version 38-beta8 candidate. Problem still was around. I tested their alpha version of 40, but still it persisted.

More googling revealed a new solution I hadn't tried: Refresh Firefox


Refreshing cleans out all prior add-on settings and caches.

Here is how to do it.

1. Click the menu button and then click help .
2. From the Help menu choose Troubleshooting Information.
3. Click the Refresh Firefox… button in the upper-right corner of the Troubleshooting Information page.
4. To continue, click Refresh Firefox in the confirmation window that opens.

The good news is this worked. My memory usage is down a lot, and pages are loading much much faster.
