FireTitle 0.5.5-1.1… unreliable with Firefox 55.0.3 and 56.0b10 about firetitle HOT 12 CLOSED

I think the bug is fixed in commit bf1f423, I uploaded a new FireTitle version to addons.mozilla.org.
If you have a developer version of Firefox, you can generate the xpi with make and try it.

👍 fix confirmed, thanks!

Restoring the session

The titles appear, disappear, then reappear at load time.

Crap.
Ok, first, the add-on isn't supposed to be installable on FF 55, the minimum version requirement is 56 since the API used is only present since FF 56.0b7.
However, I'm more sad about the unreliability with Firefox 56.0b10.
Do you have a way to reproduce the problem deterministically? What happen exactly when the title is wrong? Does the window shows the default title? Does it show another tab's title? Does it show only "Mozilla Firefox"?
Thanks for your report.

Hi, this issue is with FireTitle (works with Firefox 3.5 - 56.*), not Crappy Firetitle.

I'll take some shots …

from firetitle.

I made a long screen recording of the issue with heavily extended Firefox 55.0.3. A frame from that recording, showing six of twelve windows improperly titled:

Then, some simple shots of the issue with minimally extended 56.0b10 – FireTitle and Session Manager alone. Work in progress.

For now: I don't know whether these are contributory to the issue, but it's remarkable that not-logged-in (NLI) views of these two URLs (second and third tabs in a single-group four-tab window) present a title only whilst loading – no title when loaded:

With minimally extended 56.0b10:

OK, I made the bug reproducible. (For weeks, I sensed randomness … this morning I got lucky, pinpointed one affected URL.)

Steps

1. with 55.0.3 on FreeBSD-CURRENT or 56.0b10 on Kubuntu
2. create a new profile, named FireTitle
3. quit
4. start the FireTitle profile
5. if more than one tab opens, then manually close all except the first
6. in the one remaining tab, visit http://www.open-zfs.org/wiki/OpenZFS_Developer_Summit_2017
7. observe the title bar, OpenZFS Developer Summit 2017 - OpenZFS - Mozilla Firefox
8. show the menu bar
9. Tools menu, Add-ons, Extensions
10. install FireTitle
11. ignore the prompt to restart
12. close about:addons, leaving the OpenZFS … tab alone
13. quit
14. start the FireTitle profile
15. History menu, Restore Previous Session

Expected

• one single-tab window entitled OpenZFS Developer Summit 2017 - OpenZFS - Mozilla Firefox

Actual result

• in the title bar, either nothing (no text) or Mozilla Firefox

Workaround

• Command-R reload.

Ok, thanks, I've been able to reproduce the bug too. Apparently, some signal of "page loaded" is fired earlier now, so the page title is read before it's loaded...

from firetitle.

Great!

Incidentally, I vaguely recall occasional/rare title problems with Firefox 54.x. Maybe the sense of randomness grew during that period. Problems became much more noticeable when 55.0 arrived.

If there's a reasonably easy way to identify the Mozilla changeset(s) underlying this issue, I'll be glad to know.

Many thanks

Thanks.

I wondered whether the Firefox 55.0 beginning (or exacerbation) of this issue affecting FireTitle arose from work around Mozilla bug 906076 - (lazytabs) Virtual tabs - lazily create linkedBrowser and other dependent elements for tabbrowser tabs to improve startup performance. Related:

• The New Firefox and Ridiculous Numbers of Tabs – Dietrich Ayala (2017-07-21).

I sped through Mozilla's 906076 and some linked items. A few mentions of titles, but I could not see anything that might have led to this issue 14. I'm not a developer, just curious :-)
