After the last update (in Linux), Opera is not retaining the open tabs anymore.
I confirmed the settings are correct ("Retain tabs from previous session" option is selected).Anyone else?

Opera-QA-Team Opera last edited by@metiusau: We just tested on our side (Linux, latest Opera version) and the "Retain tabs from previous session" setting works as expected, so this might be an edge case. Does the issue happen every single time you restart Opera, or only occasionally?

When Opera first tried to update to this version, I got "The operation has failed to start because its side-by-side configuration is incorrect. Please see the application event log or use the command-line sxstrace.exe tool for more details."
And when completely uninstalling Opera (wouldn't uninstall, as the install was corrupted) I had to use CCleaner to remove Opera and its registry entries from my system. But now every time I install Opera, the browser seems to install just fine, and even opens, but then I get an error, "At least one file with resources (.pak) is corrupted. Please reinstall Opera."
I have tried everything I can think of to fix this. What the hell is going on?

@alphamachina: I even deleted everything at the following locations and still get the corrupted .pak error when trying to install the latest version of Opera. The funny thing is the last version of Opera One (before it tried to update) runs just fine, if I go run the opera.exe directly from that folder.
%LocalAppData%\Programs\Opera
%LocalAppData%\Opera Software
%AppData%\Opera Software -

@alphamachina: I also ran DISM, SFC /scannow and tracesxs (ran Opera installer during the trace, got the log, ChatGPT says the log is clean). I also completely reinstalled all Microsoft redists 2008 - 2022, x86 and x64, and used Crystal Disk Info to check my system drive to make sure it wasn't failing. I'm at the end of my expertise. Either something is wrong with this installer, or I'm missing something.

This part at least usually happens when opera.exe doesn't get updated to the new version and you get a mismatch between it and the files in the new version folder. It's pretty rare normally. However, lately, with users renaming opera.exe to msedge.exe or edge.exe due to this issue, it can happen every time Opera updates if you don't delete that msedge.exe and rename the new opera.exe to msedge.exe.
The pak file issue is harder to figure out.

@opera-qa-team: yes, it happens all the time. And also on different installations. Yesterday I was testing a new installation (Fedora) and got the same issue.
I am using the SNAP package on both. Can you eventually test if the issue is related specifically to that?

@metiusau Same issue with the flakpak package? Same with the rpm package?

Submerstep last edited byCould you please allow users to arrange the sidebar icons in any order they want?
I have extension icons that I would like to put at the top of the sidebar (below the Opera logo) but it won't let me. Nor does it let me put them above the Opera tool icons (history, downloads, extensions...) at the bottom of the sidebar.
Thanks!

@submerstep: Thanks for the great suggestion about rearranging the sidebar icons! We can’t move extension icons above the built-in Opera tools just yet, but we’ve passed this idea on to the team to consider for future updates.

This version still crashes if I'm streaming video, and attempt to open up a new tab.

@annoyed-at-updates Can you get it to crash in Opera Developer and get a crash ID there?

@burnout426 Developer's fine in this one particular respect. I can open new tabs without crashing.

@annoyed-at-updates: Thanks for the detailed report. You mentioned it happens 100% of the time while streaming video - could you let us know where you’re streaming from (e.g., YouTube, Twitch, a specific site/service)? Also, when you open the new tab, are you clicking the “+” button in the tab bar, or using a keyboard shortcut?

Google translation from Polish:
Yesterday, a problem appeared with Adblock Plus – the filter set lists aren't updating. Other browsers don't have this problem. The main question is: is the problem with Adblock or Opera? I'm using the latest version of Opera (from August 7th). I don't know if Adblock was updated after that date (I have version 4.25.0).

@rancor6: Hi, thank you for your comment. We discussed it with Adblock team and it sounds like you're experiencing issues with the Adblock extension, not Opera's built-in ad blocker.
