You don't need the if statement there, as it will almost never be set (it means it's looking for a "url" parameter in the current URL).
This should work:
<li><a href='https://translate.google.com/translate?sl=en&tl=ru&u={expression="request.url()"}'>русский</a></li>

The only reason I would say this is redundant is that both iOS and Android have built in capability to do a quick scroll to top. In iOS it’s universally just tapping the top of the screen. Android has a few different implementations but you can set it up with a gesture in any event. I understand that a button is super easy, but in this case it does seem like replication of native OS behavior. 

Jordan wanted to make Achievements cloud-only but I said no.

You heard it here. @The Old Man wants me to be less helpful.

Unfortunately, not at this time - member follows are handled a bit differently from content, so only the one option is available. You can, however, change this to show in your notifications list rather than as emails, though. In this case, followed content would still be sent as a digest email or individual email per content posted, while the followed member would go to your notifications list instead.

This was actually removed late in 3.x's life because it caused more problems then it actually solved. It was only ever meant to be run once after upgrading to 3.x from 2.x. In fact, this was the catalyst behind the entire background queue system, so it would just happen automatically.
This is the same for 4.x - the post rebuild is only ever meant to run once after you upgrade, so it cannot be run again, unfortunately.
This will only rebuild Lazy Load data in posts - not the full content.

Custom CSS:
.cAuthorPane_badge--moderator::before { content: "\f132"; } Change f132 to any FontAwesome icon (you can find the appropriate replacement by clicking on the icon on that page, and look next to the Unicode label).

Statistical graphs are generated using Google Charts. If you have any Dashboard blocks loading statistics (like Registrations, Online Users, etc.) that will be why it's calling to gstatic.com.

Yes, you can disable it in Community Enhancements.

They are not.
In the case of sessions - those are always temporary even when using the database, so them being "lost" is not an issue. If the user associated with the session has opted to have their login remembered, then it will just create a new one. Otherwise, they would just need to login again.
For views - a task runs through these and updates content items view counts accordingly. If these are lost for some reason before they are applied by the task, then they will not be processed.

Every 5 minutes.
And yes, it can be beneficial particularly for sites with a lot of simultaneous traffic as it'll offload all session handling from the database. Combined with guest page caching, it's entirely possible to serve a page to guests entirely from Redis and never touch the database.

It can break the editor and cause it to not load in some cases. I'm not sure of the configuration options for Rocket Loader, so it may not be an issue for you. Every instance I've seen, disabling it resolved the issue.

No, there is no way to safely do this.

This might do it for the front-end.

This is all you need:

Btw, cheers to the IPB support staff and management.  They took care of me!!  Wonderful folks and in this case were willing to go a little out of the way for a long time customer.  This is the type of support that won me over when I started using IPB 1.x 17-18 years ago.  Wheew!!
Pulled a screen shot from the "original skin" below, from the way back machine!  hahah!  version 1.3 in 2003!

I've been digging into this pretty significantly, and unfortunately it's a bug within Firefox itself.

Wow that's brilliant I did not have that button added to the Editor. Thanks! It just does what I was asking for 🙂 
Thanks Ryan!

There is an editor button for that.

It would be the locale defined by your language pack. Edit your language pack in the AdminCP and make sure it is set correctly. The default is English (United States) whereas you likely want English (Australia) instead.

GD is a part of PHP by default so if there are any issues it would likely be between libgd and PHP itself, rather than IPS4.
