This doesn't seem limited to first start after upgrade. Orion locked up on me and I had to force quit it. After starting it back up, I lost the controls for the tab overview, new tab, and share sheet. All were in their default location except the new tab button.

Ok, this is incredibly hard to chase down exactly what's happening, but every now and then I notice randomly that the same three items (new tab, share, and tab overview) are missing from my toolbar, without restarting or updating. Just during the normal course of using the browser, at some point I notice those three missing again.

M_L_M I haven't tried putting other controls on the far right to see if they get affected (I'm very much a creature of habit; once I have a layout set it tends to stay). However, I can say I typically notice it when closing/re-opening Orion, however in this most recent instance, I hadn't restarted Orion, it's just been there running a few days, and suddenly I noticed those controls gone again.

One thing I've just noticed today is clicking something that triggers a popup window seems to trigger the removal of the controls from the toolbar. Maybe try that in the investigation, see if you can duplicate.

@Vlad seems to be reproducible if you place those icons on the right side of the toolbar and then go through operations such as opening a new window, triggering pop-ups, etc.

Installed the most recent update, and opening a new window still triggers the loss of these controls from the toolbar on opening a new window. Hopefully this one can get narrowed down and fixed soon! It's frustrating to have to keep re-configuring my toolbar.

I believe this is the same as https://orionfeedback.org/d/3384-updating-beta-and-rc-removes-toolbar-customizations, which seems to be fixed in the RC builds, so should be fixed in the main beta on the next release.
