As a workaround disable these 2 flags and the old popup will be back.

@leocg Look what I've found https://blogs.opera.com/desktop/2017/08/exportable-bookmarks-smoother-videos-design-improvements-opera-47/

Yes, I agree with Opera, this a handy shortcut to my history log.

@leocg said in Where is the "Recently closed tabs/Tab menu" button on the top right?:

try improving tabs management

Obvious conclusion.
And not just a try, it really improved the tabs management, and 'Search in tabs' worsened it.

@Dheinamar said in Where is the "Recently closed tabs/Tab menu" button on the top right?:

new location of the list in Menu->History

This is not a new location, 'recently closed' short list has always been there. When they recommend to use OMenu > History instead they are just trying to justify their weird decision regarding the removed TabMenu. OMenu is not the same as TabMenu, otherwise the TabMenu wouldn't have been necessary and implemented at all in the past.

@nsx

Instead of simply improving/restyling the existing TabMenu and adding a search field there they replaced it with a part taken from the removed 'InstantSearch' feature (InstantSearch had the 'search for tabs' feature, by the way, but it was said that the InstantSearch was unpopular feature that's why it was removed. So it's worth asking why we have a part from unpopular feature in the top right corner now).
Now they are trying to recreate the already existing and well working tabs management popup (I mean Tab Menu), but it seems that the final result (regarding the functionality) will be worse anyway than the existing one. That what I can call as 'wasted developers resources'.

I'm also on Win 8.1 and I have various results in different browsers (Chrome, FireFox, Vivaldi, Edge Canary on chromium).
With hardware acceleration ON it does work nowhere (small difference is in FireFox where the black screen is appearing when I click 'play' button, in other browsers no response)
With hardware acceleration OFF it plays correctly only in Chrome. It also plays in Edge, but with freezes (not smooth). In FireFox and Vivaldi is the same result as with acceleration off.

@treego you can disable #search-in-open-tabs flag to return the tab menu.

@andrew84 Something like this (maybe wider) popup and all would be happy, but they trying to invent a wheel instead.

Make the 'top sites' pane optional (expand arrow or switchable off in Setting) and add 'quick action' buttons (Copy/Paste/Print/Find/Full screen/Save as PDF and similar)

*As for the shortcuts, it's better to make it customizable and offer users select what shortcuts each users want. 5-6 shortcuts for example, from the range of browser options (20 -30 most important options/elements/pages).

And my suggestion also is to focus more on options that directly refer to currently opened page and on address field/text, not on some global browsers features (that's why I'd like to see quick buttons).

@burnout426 on top there's also small horizontal scroll bar which can be moved with mouse.
Anyway, the feature is raw. I noticed that new tab button [+] is a bit away from the last tab if the flag is enabled. Also, tabs become too small already (for me personally) when there arrows appear. As was mentioned. the should be options how to shrink the tabs.

Looks like that in this bulid SearchTabs doesn't keep 'recently closed' tabs and after restarting items are gone.
Also it doesn't show 'open' and 'recently closed' sections until removing items.

• return the white menus and dropdowns (like in 83.0.4232.0)

After relaunching after the update (after clicking relaunch button on help>about page) browser started with crash massage on top. I saw the message only once and later there wasn't.

I think it should also have more predefined periods for quick search, not only 'yesterday' and 'older'.
For example: 'today', 'yesterday', 'last week', 'last month', 'last year'
(if there's no history, the corresponding periods should be grayed out)
And also asc/desc sorting option.

Suggestion (old) https://forums.opera.com/post/228116
Implement 'quick search' in sidebar panel with search engines choice (like substitution of the removed 'Instant Search' feature). Web panel extension analog but Opera's one https://addons.opera.com/en/extensions/details/web-panel/

It's still unclear why 'user custom sites' for the sidebar feature looks abandoned. I'm pretty sure these two panels can be merged and sidebar 'custom sites' can in the form of bookmarks on 'Instant Search' sidebar's panel (just like in Web panel extension).

*It works in Edge but search is limited with Bing. Btw, Edge recently also implemented search popup

css related visual issues are still not fixed

@andrew84 My vision how the 'charged' (all additional buttons are enabled in search popup settings) search popup could look.

@andrew84 By the way, along with my previous suggestions about improving the search popup and adding optional ability to quickly select search engines (https://forums.opera.com/post/248959), search popup also could have 'send to' icon/button where Pinboards list can be displayed (mby also MyFlow) if the Pinboards feature is enabled.
*Very sad that you don't want improving existing features that really help and simplify daily browsing.

There's still no direct access (in contrast to Edge's collections) to the list of pinboards in context menu. https://forums.opera.com/post/258809

In Opera is need extra clicks and movement:

right click >
select 'send to pinboards' >
move cursor to the top right because popup opens there >
select pinboard you need from the list>
click add button

Edge:
right click>
select collection(pinboard) you need from the list

*And both the visual issue while dragging pinboards cards and the giant header text when using 'Spacious' theme are still not fixed.
