Build ID: 20131215004001

Steps to reproduce:

With
user_pref("browser.startup.homepage", "http://localhost:8080/index/lasttime?sort=mtime");
user_pref("browser.startup.page", 3);
set, when one starts firefox ON A VERY SLOW SYSTEM,



Actual results:

It is revealed that firefox actually visits the homepage very briefly before switching to the last page.


Expected results:

Don't waste time visiting the homepage.

WFM on Mozilla/5.0 (X11; Linux i686; rv:28.0) Gecko/20100101 Firefox/28.0 (20140108004006), but my system is not actually slow. Unfortunately, I don't have access to such a system.

Dan, is there some way to catch this happening without a VERY SLOW SYSTEM? :)  I checked the history and Developer tools but nothing seems to be recorded of the startup page switching from the startup.homepage to whatever the page was last set at.  Do you mind checking to see if it's still the case on Nightly?

Thanks!

Well on a VT100 I would use
$ man script
So maybe something like
https://www.google.com/search?q=recording+xwindows
will work on Linux. I even know less about MicroSoft.

Anyway recording everything might reveal all kinds of wasted repainting, etc.
That way nobody would need an actual slow.busy system to check... as we don't usually have the right conditions every day to reveal this.

I can confirm this on Firefox 49.0 on Linux.

I currently run on what you can call a slow system (Celeron N2830@2.16GHz). At startup, Firefox takes several seconds before switching to the "restore session page".

During this time, it starts (but not ends) loading my home pages.
I can even start interacting with loaded tabs or load new pages before being interrupted.

Then if I choose not to restore, Firefox seems to reload my home page from scratch. As a side note, this a very painfull because the session started before the "restore session page" is forgotten (any tabs closed or opened is not remembered).

When restarting Firefox after being killed, my Firefox 60.0.1 (Linux) still briefly displays my home page before asking me whether to restore the killed session or not, so this Bug 956100 does seem to have been fixed by the fix for Bug 1054740.

Oops! Typo! Sorry! Should have read "this Bug 956100 does *NOT* seem to have been fixed by the fix for Bug 1054740".
