Firefox is extremely slow outside of safe mode, even with a refresh, a reinstall, and disabling of hardware acceleration

Posted

Topic title covers most of it.

Basically:

A few days ago, Firefox started running extremely slowly. Tabs take considerably longer to load, the browser becomes laggy when it tries to load anything, and attempting to open multiple tabs at once leads to Firefox becoming completely unresponsive for some time.

Attempting to refresh had no effect. Safe mode made it run at full speed, but disabling all add-ons did nothing under normal circumstances. Disabling hardware acceleration caused Firefox to go from "unusable" to "frustratingly slow". Disabling WebGL had no appreciable effect. Installing new drivers for my processor and graphics card had no effect. Restarting my computer had no effect. Removing cookies had no effect. Clearing the cache had no effect. Disabling Sync had no effect. Reinstalling Firefox by renaming the old install to "Old Firefox" had no effect.

I'm using Firefox 46.0.1, 64 bit.

I can't provide info on my plugins right now, as I'm posting this in Chrome because of how slow Firefox has become.

A speccy snapshot of my computer is right here: http://speccy.piriform.com/results/vUlsCY1KK83gUZAKOebuwys

Please help.

As I outlined earlier, Firefox works swimmingly when in safe mode; however, disabling hardware acceleration and extensions while running Firefox normally have no effect, creating a paradox which I can't explain.

  5. Remove the check mark from Enable hardware acceleration.
  6. Click Close to close the Adobe Flash Player Settings Window.
  7. Restart Firefox.

This Flash Player Help - Display Settings page has more information on Flash Player hardware acceleration, if you're interested.

Disabling hardware acceleration for Flash had a slight positive effect on Firefox's performance, but it's still quite slow and laggy compared to before. More input is requested.

Some of your crash reports weren’t sent to the Mozilla Servers.

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.
