1202297 - Tabs opening slowly can affect other tabs.

Status: RESOLVED WORKSFORME

(Firefox :: Untriaged, defect)

Description

[login+mozilla-bugzilla]

User Agent: Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/44.0.2403.155 Safari/537.36 OPR/31.0.1889.174

Steps to reproduce:

With one tab open, say to google.ca, open another tab, use a bookmark, and quickly switch back to the first tab.


Actual results:

Depending on how quickly the switch is done, either both tabs now show the bookmarked page or the google.ca tab now shows the bookmark page and the new tab still shows the new tab page.


Expected results:

There should be two tabs open, one google.ca and one something else (from the bookmark).

Notes:
This is very much a speed issue. It doesn't seem to happen on a fresh profile; I have 15 extensions running on the one where it can happen, but this is a rather large issue nonetheless - most, but not all of the time it happens (probably also depending on the speed) the overwritten tab's back button greys out as if the tab were new, and it's possible who-knows-what could be removed.

Maybe add-on issue.

viko, have you elimiated the possibility of addons by disabling all of them, or one at a time?

Apologies for replying late.

The issue appears to have disappeared. Depending on whether it was an addon or Firefox issue it may have been fixed in an update to one of those.

My best guess is that it was a speed issue; I had enough addons installed that opening new tabs was slow, but it was still a Firefox issue as no particular addon could be blamed.

That said, however, it's irrelevant now. Please close (I would, but I'm not sure which status to apply).
