I'm a bit OCD when it comes to my sessions. I never start a new session. Normally, I crash the browser (via Task Manager) or it crashes on its own and I only load up a few tabs. But even then the CPU hits 90-100% within 1-2 mins. Should I get rid of some of the tabs I have open even if they are not loaded/are not active? Should I start a new clean session? Wondering if my plugins are the culprit?

Adobe Flash Player Shockwave Flash 23.0 r0

I have the latest version of Firefox.

Start Firefox in Safe Mode {web Link} by holding down the <Shift>
(Mac=Options)
key, and then starting Firefox. A small dialog should appear. Click Start In Safe Mode (not Refresh).

Is the problem still there?

While still in Safe Mode,

In the address bar, type about:crashes<enter>. Note: If any reports do not have BP in front of the numbers/letters, click it to submit them.

The crash report is several pages of data. We need the report numbers to see the whole report.

Using your mouse, mark the most resent 7 - 10 crash reports, and copy them. Now go to the reply box below and paste them in.

(Please don't take a screenshot of your crashes, just copy and paste the IDs. The below image is just an example of what your Firefox screen should look like.)
