Restricted Differential Revision / R755:bd112d9c53d0: Update firefox to 62.0.2

I have the same issue here: I have to wait a bit when I hit ctrl + q or when I click on the close button.

Not a real "issue" imho, but I'm facing it too. Solus Budgie - Shannon branch.

I feel it too!

Does this occurs since Quantum or since FF60?

I just tested this while reading this. What did you have to close (within the application)? I had a few tabs open (with some add-ons such as ublock, uMatrix, Stylus and DuckDuckGo Privacy Essentials) and it took a literal second and it closed down fast.

Note: Using Solus Budgie with FF60

Hello,
In fact I noticed it closes faster if you have a more powerful computer.
I'm now using a very recent computer and it closes as fast as it does with other applications, but when I use my seven years old netbook, Firefox seems to freeze and closing after one second or two seconds.
As far as I saw, it does not depend on the number of tabs opened.

(I am using the latest solus stable, so yes it happens with firefox 60)

Just to be clear, I find 1-3 seconds being fast and anything above 10 seconds to be "too slow".

@josephscade I don't want to sound like a smartass but yeah that's a given. On my system I have an SSD via PCI-E (x4). Still people should be more clear on what they mean by slow since like you said, hardware is a factor (as well as set up, add-ons, etc).

I've i5 3rd gen along with 8 GB RAM and samsung 850 pro SSD.
I've tried a lot of distros (Manjaro, Arch, Ubuntu, Mint, CentOS and so on) and this problem happens only on Solus, it's definitely not hardware-related.

3 seconds to close a browser which closes instantly anywhere else is not considered fast for me.
Plus, i only use µBlock.

Another thing : It closes instantly as I said on latest ISO (from August 2017, un-updated), i'll tell which version it was. (probably 56)

I'll stick with Opera in the meantime.

To point it out, to me it's slow to close only with CTRL+Q, clicking on the X closes it light-fast.

It's slow for both actions to me.

Its slow for both actions for me too.

Ok, I know exactly why this happens, and can reproduce it from the binary from mozilla (thanks strace).

Firefox opens every single .xpi file on close (I cannot possibly tell you why). The reason it closes quickly is because it includes very few .xpi files. The Solus version ships with many lang packs which it's opening all of them on close...

Enabling all the langpacks on the binary version makes it slow to close. Disabling all the langpacks on the Solus version makes it close instantly.

After the ypkg updates with fixes for PGO and LTO, is it possible now to build Firefox with LTO and PGO then?

No, when it is able, it will be the first thing that is done
