I was reading this thread: https://forums.opera.com/topic/39170/where-is-the-recently-closed-tabs-tab-menu-button-on-the-top-right and found this comment:

I tried it out and it worked

The tabs button is back.

@mychakk In version # 70.0.3728.71 (for Linux) the flag "search-in-open-tabs" unfortunately is no longer available.

As you mentioned, the magnifying glass icon has a set of closed and open tabs, but only for the current device

Also, the Tabs icon for the side bar is still buggy. It is sometimes available and sometimes is missing. However, if the icon is missing you can still access to the list of tabs by typing opera://activity in the address bar.

So far, it seems to be the only option since the "search-in-open-tabs" flag has been removed.

@burnout426 I just did it and it worked. The button is there again at the top bar.
I used it to syc with the tabs on my other devices so it is good to have it back.
Thanks for your help.

@leocg Well, I'm glad to know that the sync function for the tabs is still available.
I would prefer to have the dropdown button back, on the top bar, next to the search button, but I can use the link to 'opera://activity' in the Speed Dial as a workaround, until the erratic button in the sidebar gets fixed.

@mychakk Interesting discovery you have made.

Thanks to your comment I tried to open a new window and had the same result, the Tabs button now shows on the new window (although, it won't happen on a private window):

However, as you mentioned, next time I open a new instance of Opera it is missing again on the Sidebar. It is not even on the option menu to check it.

And for the sync icon, it's behavior has been the same since I can remember. It will only be displayer when you choose to log in from the Opera menú. I think it is because it works like the Download button, which only appears when you make a new download, so it never bothered me.

@mychakk Thanks for your step by step guide.
I will try a clean installation. My current configuration is the following (in Spanish):

• Versión: 68.0.3618.63
• Opera se encuentra al día (Opera is up to date)
• Flujo de actualización: Stable
• Sistema: Solus 4.1 Fortitude (x86_64; Budgie:GNOME)

It was updated a couple of days ago, Before the update I had the 'Tabs' button in the side bar, just between the 'News' and the 'History' but now is missing.

In the meantime, have tried this tip and it worked, so thanks to leocg:

@leocg said in Other devices active tabs:

@MrPatyk You can see other devices opened tabs using the sidebar, although it may be a little erratic, or by typing opera://activity in the address bar.
