1481285 - I continually have issues with Firefox taking a long time to load pages - especially SharePoint related pages

Status: RESOLVED INCOMPLETE

(Firefox :: Untriaged, defect)

Description

[jonathan]

What did you do?
================
1. Click a link or type in a URL
2. Wait
3. Wait
4. If nothing's happened, resubmit the URL or refresh the page.

What happened?
==============
Sometimes the page will load halfway, sometimes it won't load at all. I had a page load this morning most of the way and I left the tab open for a couple hours and it still showed it was trying to load.

What should have happened?
==========================
Fast web browsing, with everything loading as expected.

Is there anything else we should know?
======================================

Hello Mike, can you please take a look into performance profile here? Thanks!

Hi jonathan, thanks for your report.

I'm afraid the profile doesn't tell me much - the browser spent a bit of time rendering a page, and then was mostly idle (although the compositor was animating something).

Does this happen for all pages, or a set of particular pages? Can you reproduce in Safe Mode (Help > Restart with Add-ons Disabled)?

This happen pretty regularly - particularly with SharePoint 2013 pages it seems. It's not consistent. It's like there's something somewhere that causes the browser to hang and it can't move past it. Sometimes if I refresh the page, it works right away. Sometimes I have to refresh the page several times and sometimes the exact same page loads exactly as expected, right away. I don't seem to have any of the same issues with Chrome or IE.

I've tried restarting with add-ons disabled and the issue still seems to exist. Only difference is Firefox seems to stay on the current page a lot longer rather than jumping to a blank screen right away and then trying to load the new page. For reference, I only have two add-ons with Firefox right now (I did another reset of the browser last week) - Adobe Acrobat and Webcompat.com.
