I am at wit’s end! On the verge of booting out Firefox! However, the pesky problem at hand only affects the one of my desktop computers, so I trust that there HAS to be a solution. I will explain what I have tried, in stages, and what seems to have worked on the one PC…
Firstly, I tried to “downgrade” (from version 29 to version 28) in Yast, but there was no way I could find to do that (I went to Software Management, entered “mozilla” in the view/ search field, and when the Mozilla package came up, I clicked on the “Version” tab below, hoping to find a way to boot version 29 out… it appears in the Main Update OSS and in the Update Non-OSS repos… but this wasn’t possible). I finally found a solution whereby one simply force-installs a previous version, like so (for version 28):
zypper install --oldpackage MozillaFirefox-28.0-17.1.x86_64
But the “bug” kept bugging me, wanting me to upgrade Firefox. Then I learned that a way to kill this urge was the following… in about:config, set to the value “false” the following entries:
In Firefox itself, I went to Edit > Preferences > Advanced > Update and UNTICKED the Search Engines box (until recently, one could untick ALL updates, before Firefox went WUSSIFIED).
This procedure has worked on my Linux-only machine, but on my dual-boot machine, the “bug” comes back to bug me almost the second after I force-install the downgrade. Anybody got a good idea for how to get rid of that pesky, queued Firefox update that refuses to accept that a No! is a No!?
(I uninstalled and reinstalled a couple of repos in connection with uninstalling and reinstalling VLC Player, but I can’ recall if I did this only on the dual-boot machine, or on both of them.)
