Version: 38.2.0esr-1~deb8.1

Severity: important

Since upgrading from 31.6.0, the search bar fails to display drop down list of alternative search engines;
I have checked searchplugins and the alternative search engines are still listed; the search symbol displays a vague down arrow
but does not display default search engine icon and does not produce the list of search engines when left clicked. The normal behaviour
is for the default engine icon to be displayed with a distinct permanent down arrow to select an alternative. This behaviour
is corrected by reverting to 31.6.

Kernel: 3.16.0-4-amd64 (#1 SMP Debian 3.16.7-ckt11-1+deb8u3 (2015-08-04))
Desktop Environment: XFCE Version 4.10

This is to replace #796128 which has a rubbish Subject line (sorry).

src:iceweasel has been superseded by src:firefox-esr in version
45.0esr-1 in March 2016. Transitional packages to ease upgrades were
provided in the wheezy, jessie, stretch and buster releases. The
transitional packages have been removed finally before the bullseye
release in August 2021.
After regular security support for buster ended in August 2022 and LTS
support ended in June 2024, I'm closing the remaining bug reports now.
