firefox update from store does not work

Running firefox 52.0 want to update to 57. In the store it shows firefox 57. with the option open (not install, I must have installed it already???). Anyway when I click open it simply opens 52.
What am I overlooking?

Location. Check the desktop icon.

By default, firefox installs in /opt. Your distro probably installs in /usr, or /usr/lib64 or some such. You have put firefox-57.0 in /opt, but are still running the one in /usr/somewhere.

I find firefox 52 in /usr/lib
firefox 57 i cannot locate

Did you install it?
If you have locate, run 'sudo updatedb' and then 'locate firefox'
If you have slocate it's 'sudo slocate -u' and then 'slocate firefox'

Yes I installed it by clicking the icon in deepinstore.

Trying to locate it now with both commands you gave above. Both return ´command not found´

Hmmph! What's your distro? These are pretty basic commands.
I presume firefox-52.0 was installed by your disdtro, and firefox-57.0 was a download from Mozilla.com. Is that correct?

Try these then

which firefox
cd /opt
find -name 'firefox*'
cd /usr
find -name 'firefox*'

The finds may take a few seconds but don't worry.

I run deepin 15.2
This is what Deepin File Manager returns

/usr/share/firefox
/usr/lib/firefox
/lastore/metadata/firefox
/etc/firefox
/tmp/firefox_joline

It looks like you haven't actually installed 57.0 at all.

I agree. That is what it looks like. yet the firefox 5.7 icon in the shop does not give me the install option, only the ´open´ option which means -as far as I know- that it has been installed or at least the installer believes it has been installed.

For now, the only option I can think of is uninstall firefox 5.2 and do a fresh 5.7 installation. But I do not fancy loosing all my preferences... Still hoping for another solution. So far all the applications that are available in the deepin store have been easy to install with one click. No problems there before...

Convince yourself. In a terminal

bash-4.3$ firefox --version
Mozilla Firefox 57.0

Mozilla Firefox 52.0.2
I alread knew it was opening version 5.2 instead of 5.7
Aparantly the install of 5.7 from the store does not work.
The question really is, how to install 5.7 as an update so I do not loose by settings if it does not install from the store...

Wait for an update. As one who has it, it's not that much faster better, and your a** weon't shine in the dark just because you've got it.

It is faster; It's not clunkier/slower. But you need a stop watch to be sure. It was getting slower than chrome despite chrome's busy spyware.

Atually the only reson I want it is because video downloader is not running on the 5.2 version.

I am using another one now, but not so happy with it...

Anyway I will wait a bit....

Had trouble with older laptop doing similar things when trying to upgrade to Quantum FF.
Started with FF-42
Had to upgrade GTK to a gtk+3
Decided to go with Firefox-56.0.2

<cd (to directory desired)> then

wget http://ftp.mozilla.org/pub/firefox/r...56.0.2.tar.bz2

56.0.2 is my preference, anyway.

Best wishes!

Have you installed Synaptic? If not, you might want to install it from the store and then use it to upgrade Firefox.
