Do more on the web, with a fast and secure browser!
Download Opera browser with:
With new version 100.0.4815.76 (or the one .5x before), the bookmark folder names aren't partially not shown anymore. I'm sure they were there with the previous build .54(?)
Missing names of the folders are "Prio 1" and "Prio 2".
Folder names on the parent and childs are shown.
Another poll/request/wish to get tab grouping / stacking in Opera soon?

Also lost my tabs again from only one workspace, but not after the latest update:
Problem: After a download of a PDF I double clicked in the download notification and it should open - but it didn't for me - but it did on the 2nd monitor but on this I'd running my company laptop on HDMI 2 for days.
Only in rare cases I switch the 2nd monitor to HDMI 1 - my PC 2nd monitor.
Finally the Opera window 2 was open on HDMI 2 which I've never seen. Closed Opera on main window last night. Turned on today. All tabs lost on first workspace - maybe because from that I'd opened the PDF.
I noticed this situation ~ 10 days ago when I lost all tabs in another workspace. In this case I've moved a window to the 2nd monitor, closed the window first, then the main window. But next day I'd lost them also.
There should be a warning when closing the Opera main window (started first) and another Opera window is open so we can cancel and close the other Opera windows first - also on not active 2nd monitor.
However - my little small Opera startup script saved it all 
and I was able to restore the previous session with all tabs - more or less.
I recommend to use it until Opera has a better solution:
When opening a Markdown file (local double click or via http) it would be nice if Opera would display this file "nice" and not like as a simple .txt file.
Opera could offer various CSS styles (incl. plain txt of course) in preferences how to open .md files.
A right click context menu on the .md page to choose quickly another CSS style would be also good.
In March 2016, text/markdown was registered as RFC7763 at IETF.

and google around 
After another year, MS Edge 129.0.2792.79 still shows the as tab title the nice file name I've given my local PDF file.
Opera still shows the dumb "name" of the properties of a PDF.
E.g. I've over 200 security transactions PDFs per year and all have the same PDF title "BFOEncoder output" (generated by big companies). I want to see my local file name as for other files - e.g. when I open a TXT file with Opera.
When I open multiple PDF's with Opera I never know from the x open tabs which PDF is it. With the correct file name I would see that.
Currently I double click a PDF and MS Edge opens for it until Opera is willing to change it.
This situation is drives me nuts - more than missing tab stacking years ago and is the most stupid thing I've seen in Opera since version 6.
Don't tell me you can't change it! Make an option what a user wants to see!
Thanks
When I click on a Mixcloud link (which I receive per email) - Opera loads Mixcloud and before the mix starts to play Opera results in:
There is still enough memory - the problem is the process. Did not happen with Opera 66.
@aoirei Yes , Opera 12 tab stacking. All the time most used feature ever. Missing it so much. Just have 34 tabs open - from sw development, music, shares, social, lottery & betting .. would love to group / stack them within tab groups / tab stacking within one Opera window.
@burnout426 Thanks a lot. Will try with Opera 67 when it works. Had to downgrade.
@aoirei said in Another chance for tab grouping / stacking (when Chrome is working on it):
@leocg That does not look as useful as Opera 12 tab stacking. Chrome's solution is better.
Exactly.
I just tried it in the office where Chrome is standard browser.
It's not the same as Opera 12 tab stacking.
I can not use this Chrome grouping and disabled it.
Still waiting for classic easy usable Opera 12 tab stacking.
I just tried to compare 2 monitors on
In MS Edge 134.0.3124.72
When you press the right circle for the comparsion a window at the bottom pops up - listed with these 2 monitors and I can press the blue compare button.
In Opera 117.0.5408.93 the bottom window doesn't appear. Also tried various settings with ads yes/no but no luck.
Any idea?
I just tried to start to write an extension:
At first, on https://help.opera.com/en/extensions/basics/ under the text "read our article on it" the link results in 404.
On the same page please update the example "default_icon": "icon.png",
name of the icon.png to a file name with a size as you did before. This would make it easier.
Please offer a download of an example icon set to make a how-to-start much easier and faster.
After I'd installed it I see an error "Manifest version 2 is deprecated, and support will be removed in 2024. See https://developer.chrome.com/docs/extensions/develop/migrate/mv2-deprecation-timeline for details."
So please update the example to the new version.
Thanks a lot

Sorry für späte Antwort, ich war leider auf Urlaub.
Gute Frage. Gerade nachgesehen, finde da aktuell nichts. Kann mich nicht erinnern. Evtl. meinte ich, ich habe es auf Disabled gestellt und FB Seite neu geladen und dann wieder aktiviert. 
Mysterious. Not for me.
All works incl. Edge + Facebook.
Only Opera + Facebook no sound anywhere: Built-in, Monitor, USB-C external A/D converter.
@burnout426
I think he means since Opera 108 (mine is 108.0.5067.29) there is no sound on Facebook anymore, e.g. watch reels with audio produces no sound on any on my output devices.
Youtube.com itself works.
Facebook sound works on MS Edge 122.0.2365.80.
Any idea?
Anyone else does have this effect?
No workspace names beside the icons?
For a few versions there were workspace names in the menu visible. Since the past 2-3 versions they are lost again.
Opera version 106.0.4998.41
@burnout426 said in Tab name is always "BFOEncoder output" when I open local PDF file:
MS Edge doesn't support the title property at the moment, but since Chromium does, it's likely that Edge will start doing as Chromium eventually.
After 1 year and 2 month, MS Edge still is showing the nice local file name in the tab for the PDF and Opera doesn't.
Sad that I still have to use MS Edge for PDF's for the past 14 month and not Opera. Always at the end of the year when I sort out a few hundred security transaction PDFs it drives me nuts.
I hope Opera is able to make it better for users.
I want to see my local file name of the PDF and not the garbage of companies (like my bank where I'm software developer included!). Also they generate always the same name like "Security Transaction" or nothing (undefined) as title - not the specific things I want (which paper and transaction date etc. in file name). So the file names stored on our disc is essential and most useful and not the hardcore ideology of Opera.
Thanks
How can I delete all cookies and other cached things of websites which I haven't visited the past month or whatever?
I only want to specify a date and run delete.
I've just l looked into %LOCALAPPDATA%\Opera Software\Opera Stable:
The folder "Media Cache" has only files created & modified back in 2019. It looks like this folder isn't used anymore and I can delete?
The folder "Certificate Revocation Info" has only files created & modified back in 2018. It looks like this folder isn't used anymore and I can delete?
The folder "System Cache\Cache_Data" has 5 files and only data_0, data_1, data_2 have actual modified timestamp. data_3 and index are from 2022-01-23 (modified, created).
The folder "Cache\Cache Data" has 916 files and only 20 are older than a month.
The folder "Default\Cache\Cache_Data" has 1860 files and all have creation date from the past week.
The folder "Default\System Cache\Cache_Data" has 5 files (data_0 - data_3, index - all with actual file dates.
I'm wondering that there is no option to delete the data as requested in my question. Or I only can't find it.
Maybe there are some old local app folders which I can delete? I looks so. I' using 103.0.4928.34.
Thanks for the help - and clean-up support.
