Through Chrome, Chromium and Firefox all works fine in terms of the GNOME Extensions site. However, if one is to use Epiphany then there is one hell of an issue with updating extensions. So if I went here https://extensions.gnome.org/local/ in Epiphany and tried to update an extension with little green up arrow, then for a few of them it might work, but sooner rather than later I would just get a big white on red "ERROR" message where the buttons would normally be. At which point, if I had tried to update extensions which were disabled at the time of me trying to update them, they would become enabled and be stuck on that mode until I restarted my machine.

It also appears to break a lot of things with gnome-shell, though what it does each time appears rather random. This issue was present in GNOME 3.22, but certainly got worse with everything in the AO breaking with 3.24.

If I try to disable or enable any of the affected extensions using the gnome-tweak-tool then I am unable to move the slider and there is a little "error loading extension" (gnome-tweak-tool_Extension_Errors.png) next to each one, I am also unable to get the "Remove" button to work.

I have also attached some screenshots of the kinds of strange things that occur when I do this. You will also notice the "Applications" and "Places" (Applications_Places_Menus_Showing.png) menus being present, those extensions are some of those that weren't on originally, but then got jammed on when I tried to update them even though I never actually tried to turn them on. If I then restart my system I can disable and even remove them, but not until a full restart is performed. Not even restarting gnome-shell seems to work.

I have also noticed that after I start seeing "ERROR" on the website that I get the same or just the update arrow reappears a few seconds after clicking it with all the other extensions and thus am unable to update them. This is all rather annoying.

Note: Any strange big white boxes or black boxes in the screenshots are just me hiding personal information etc.
