Bug 1720534 - Clean up styles in Bookmarks Menu Button menupopups on Windows 7 and 10. r=desktop-theme-reviewers,dao

Mike, were these intentional removals? If so, we should probably also drop e.g. https://searchfox.org/mozilla-central/rev/4b49a0dc50104e03ecadd1fd1902b27be6b9c0c8/browser/themes/osx/browser.css#152 ; if not, I guess we should put the icons back?

Since we're looking at a cosmetic issue, this is more on the lines of an S4, hence setting as such.

Hm. This might be right, or it might have been a misinterpretation of the IA deck that got put together for these panels.

Hey Meridel, should the "Bookmark Toolbar" and "Other Bookmarks" item in the Bookmarks toolbar button menu have icons, like we have for the folders? We used to have them, but they got removed for Firefox 89 - was that removal part of the design, or did I misinterpret?

According to my records (see screenshot of Figma designs with the placeholder globe icons), both "Bookmark Toolbar" and "Other Bookmarks" item SHOULD have icons. I am not away of any reason why those would have been removed.

Now, at the time we designed this I believe we were waiting on icon delivery so perhaps we need direction on which icons to use? Emanuela, do you recall if we intended for this to be a globe in each case? It seems like the folder would make more sense than the globe...

fwiw in the Bookmarks menu on the menubar the icons are appearing correctly. If we decide it should look otherwise we may want to match that menu as well.

Emanuela is out until after the cutoff for 92 uplifts so if we want to not regress this in 92 we can't wait for her. I'm going to assume that we should at least revert the icons for now, and if we then want to update them some more we can do it in 93/94.

Approved for 92.0b7.

https://hg.mozilla.org/releases/mozilla-beta/rev/db7efb8d1e83

Verified - Fixed in latest Nightly 93.0a1 (build id: 20210820095755) and Beta 92.0b7 (build id: 20210822190301) using Windows 10 and macOS 10.15. The bookmarks toolbar and other bookmarks icons are displayed accordingly in the customized toolbar Bookmarks menu.

Dropping old NI request. This presumably is not a priority at the moment, and if the icons are desired to be changed in the future, this will likely come from UX.
