Haha! Hello, fellow longtime Firefox user. I also vividly remember this term in Firefox's marketing a long time ago, but the most recent results on Google are from circa 2010. Seems they've largely dropped it as a public-facing term :)
When I called it "the hamburger menu", I got confused stares. Maybe if the top line looked more like the top of a hamburger bun… although why a hamburger should mean "menu" is still a bit odd.
I hate Safari's address bar. One visit to a mistyped address can ruin your suggestions forever, that typoed URL will be always preferred over the correct one.
Firefox's address bar is indeed great. Always works flawlessly.
Answer: don’t show anymore than three history suggestion items and provide no way to increase it
Absolutely. At the current computer I'm at, I last visited https://github.com/austinhuang0131/instagrabber in May 2020, and typing either "insta" or "austin" in the addressbar still shows that URL as a suggested address.
As usual, there used to be an add-on for that, which was subsequently broken by the move to webextensions (and even if somebody wanted to rewrite it, the webextension API doesn't cater for its full functionality). Thankfully some kind soul has maintained a version hacked to still work even on a current Firefox (https://github.com/xiaoxiaoflood/firefox-scripts/tree/master...).
Still awesome though.
So that doesn't work.
I also don't want to search my default search engine. I want tab to search for the panoply of websites that the omnibox will search. When I start typing ebay, I want "tab to search ebay".
I know I can set them up manually (a pain, but might be worth the investment to avoid the google overlord), however, I still don't get the "tab to search blah" function with a keyword. I have to type the keyword exactly -instead of having tab function as autocomplete- then space for my query.
What I want is omnibox tab to search.
You can configure Firefox to do this with a single checkbox. Go to Settings, click Privacy & Security on the side, go down to the Address Bar section, and make sure that "Search engines" is selected.
When I do that, I can click in the address bar (which brings up the drop-down), type "ebay", and then you'll see "Search with eBay" appear below in the drop-down, and then a single Tab puts it into eBay search mode.
Autofill segment would be really useful, and no modern thing seem to be able to do it. But tab to search doesn't look very useful to me.
