    Project mention: Firefox 86 Introduces Total Cookie Protection | reddit.com/r/technology | 2021-02-23

    It's a feature so that you can drag the window easily if your tab bar is full. You can get rid of it by enabling the title bar, but that's even uglier imo, before - after. Another alternative is just using a theme with an entirely different layout, like firefox-sweet, not sure about this one specifically on windows tho.

    Project mention: YSK about Terms of Service; Didn't Read | reddit.com/r/YouShouldKnow | 2021-04-06

    Why YSK: Terms of Service; Didn't Read (ToS;DR) is an open-source internet browser add-on that goes through the Terms of Service (ToS) of a website whenever you enter one. Each website (provided it's been reviewed) is marked with a rating from A to F (A being the highest and F being the grade I got in mathematics), depending on how safe or sketchy the Terms of Service are. It highlights the notable parts of the ToS and gives each point either a thumbs up or a thumbs down, again, depending on how safe or sketchy that part is. ToS;DR is a very useful add-on if you wish to know how reliable a site is without having to go through the Terms of Service. TOS;DR is available for Chrome, Firefox, Microsoft Edge, Opera and Safari.

  • GitHub repo FirefoxW10ContextMenus

    Emulates the Windows 10 context menus in Firefox.

    Project mention: Make Bookmark Toolbar Drop-down and Selection Match Theme | reddit.com/r/FirefoxCSS | 2021-03-11

    if you wanna save some time styling this stuff, I'd suggest just reading through the stylesheet I just sent you and testing the rules to see how they affect it. keep in mind there are variables in there for colors and stuff, the variables are set in uc-variables.css on the same repo. I'd just replace them unless you're gonna use the whole thing. you can also do the same kinda thing with this stylesheet, it's of a similar scope to mine but with a different style. I think it might be missing a couple of the newer context menus though, so if you're going to use the selectors from one of these, I would suggest using my selectors. I update this repo pretty frequently and new context menu stuff gets added to firefox pretty frequently too.
