I added something like this now. But nothing fancy.
Update, and enable it in the Greasemonkey/Tampermonkey menu.
It doesn't affect Wishlist/Reccomended pages and searches.

Are you sure it's not Steam's usual stupidness? It tends to log you out frequently if you have the client open and logged in in the browser. You need to check the Remember me button in the browser to prevent that from happening all the time.
Asking because I use this script and not even on my freshly installed system did I experience anything like that.

Weird, usually my script only contact steam directly if there's an age check on the game. Otherwise it uses YahooQL to get the needed info. Because of that few requests are made to steam, so it's probably something else. I'll think about what can be causing it.

Same happens to me. Installed this script yesterday and it works fine, but somehow it causes Steam to log me out of the web version. And not just occasionally, like it sometimes happens with Steam, but all the time.

Probably some update in the browser or system changed the fonts.
Use images instead, by changing 1 config in the script. Ex for Greasemonkey:
Option Icons [2].

how'd you change?

Thanks for letting me know.
It was because of the VR features that this game have.
I made a temporary fix for that. It works, but the VR features doesn't have a hyperlink, for now.
Later I'll make these hyperlinks work.

Well, to be honest, this fix only works if the user is also using my script, otherwise it will actually insert the rating after the date. To Alpe: if you really want to make it compatible with my script, you could do

document.getElementsByClassName("EGBDescription")[0].insertAdjacentHTML("afterEnd", "your html");

Although this would only work if your script runs after mine. Otherwise you would probably have to do

document.getElementsByClassName("giveaway__column--width-fill text-right")[0].previousElementSibling.insertAdjacentHTML("beforeBegin", "your html");

I would like being able to disable the mouseover popup as well. Alternatively if there's a possibility to make the mouseover area a bit more restricted, like only showing up over the ratings area. It's no biggie but for some reason the tool tip feels out of place when it's so much information and it's showing up almost everywhere you point the mouse.

Should be something like this:

Done. See if this size is good.

Seems to not work when steamgifts v2 giveaway filter was enabled. Even if I didnt filter anything with that script.

Try to remove the script, restart firefox and add it again.
If that doesn't work, try to uncomment this line (line 142):

if(loaddata('dbversion') !== false){ clearstorage("Old version."); restoredefault(); }

Changing it to:

//if(loaddata('dbversion') !== false){ clearstorage("Old version."); restoredefault(); }

Any error on the developer console? CTRL + SHIFT + (K on firefox, J on chrome)
What is the last message the script prints?

Oh, and it still doesn't work even if you disable all other scripts that you have? (just for testing)

Update and see if it works.
This happens even if it's the only script enabled?
