Auto-show/hide sidebar by mouseover doesn't work on latest Firefox Nightly

[YHNdnzj]

After updating to today's Firefox Nightly, https://github.com/piroor/treestyletab/wiki/Code-snippets-for-custom-style-rules#auto-showhide-sidebar-by-mouseover-hover doesn't work for me anymore. Is there a way to fix this?

For 107.0a1.20221003.11 it does hide, but is still much wider than what I specified in userChrome.css.

I tried it in nightly and see what you are saying. (It works fine in the beta channel) It looks like there is probably a defect in nightly that needs to be fixed. I think you are going to have to wait until this is resolved on the Firefox side.

I see Dev Ed around 50px minimum and Nightly around 210px minimum ... both seem to expand to the same size.

Well, still not fixed on 109.0a1.20221202.23...

Removing xulstore.json in your profile to clear old size of Firefox's UI wrongly stored and restored possibly solve the problem. Could you try that? @YHNdnzj

@piroor I didn't find xulstore.json, but only a directory named xulstore containing data.safe.bin.

Tried removing it and it got worse with a weird white border...

Oops, I totally ignored the wiki update... Adding !important fixed this for me :)
