Dark mode remains unchanged—at least on Linux (I’m using Ubuntu 22.04.05 LTS, and my version of Opera is the Snap package). It still has very unsightly brown borders (see the attached screenshot). Furthermore, there is an issue with download links—for example, from services like MEGA: when you paste a link and press Enter, the expected pop-up (asking where to save the file) does not appear. I am experiencing this right now; the browser treats the file as if it has been downloaded, yet nothing shows up in the download area near the address bar. To find it, you have to go to "Downloads" under "Show more," click the three dots (...) to open the menu, and select "Copy download link." You then have to paste that link into a new tab and press Enter; only then does the save pop-up appear, allowing you to choose a destination. Once that’s done, the file finally shows up in the download section near the address bar and in the "Downloads" list under "Settings." I hope they fix this—I’m not sure if it’s limited to Linux or if it also affects Windows and macOS. This is a critical function, and it’s baffling that such a serious bug exists. Interestingly, if you are already logged into a service like MEGA and click a download link from within that interface, the save pop-up does appear. It seems the bug causes the browser to open a new tab and immediately close it. Disabling the built-in ad/tracker blocker doesn't help either; the bug persists regardless. This has been happening since the Snap team released version 140.0.6074.11 as "stable" just yesterday, and today it updated to 140.0.6074.17—which isn't the version mentioned on their blog (where the title just says "140"). Furthermore, both versions use the same Chromium engine: 157.0.8103.39. Could a moderator or someone knowledgeable about Opera explain this error? It’s a disaster—not just for people working in offices, but for home desktop users as well.! I’ve attached two screenshots: one showing the dark mode issue and the other showing the version from Snap that’s currently labeled as "stable."

Critical Download Regression in Opera 140.0.6074.17 (Windows 11 x64)
Hi Opera Team,
Please look into a severe download regression introduced in build 140.0.6074.17:
Downloads generated dynamically in the client/browser memory via blob: / data: streams or JavaScript-triggered file downloads (e.g. generated CSV, text, or export files in Google Gemini chat interfaces) fail instantly with an "Interrupted / Cancelled" status. The native Windows "Save As" file dialog either fails to spawn or the stream terminates immediately before writing to disk.
Key details:
- Environment: Windows 11 26H2 (x64)
- Affected Build: 140.0.6074.17 (Chromium 157.0.8103.39)
- Verification: Rolling back to Opera 139.0.6053.38 completely resolves the issue—the exact same file streams download immediately without any errors. Testing the exact same chat session in Microsoft Edge also works without issues.
- Toggling "Parallel downloading", built-in ad/tracker blockers, or the download prompt settings in Opera 140 does not remedy the stream drop.
It seems the updated Chromium download pipeline / download bubble service intercepts or prematurely drops temporary in-memory streams. Please investigate and push a patch for this in the next maintenance build.

@leocg Just try generating a simple CSV-File oder PDF document in Gemini. It can't be downloaded in the chat window. If you click the download button a small window opens but instantly breaks. The download stops or doesn't even begin in the first place.
The Save As-Dialogue does not appear. So for me it's unusable, because I integrated Gemini in my workflow and need to be able to download certain files it generates for me.
With previous version 139 everything is OK. Something is broken with the download system in Opera 140.

@steeveboy: I can confirm that this exact same regression also affects Linux (Ubuntu 22.04.5 LTS, official Snap package) on builds 140.0.6074.17 and 140.0.6074.18 (Chromium 157.0.8103.39), so this is definitely a cross-platform issue in Opera 140's download pipeline, not an OS-specific glitch.
Just like with Gemini's generated files, any site that triggers client-side / in-memory (blob: / JavaScript) downloads—such as MEGA when downloading a shared link without being logged in—fails to trigger the "Save As" dialog:- A temporary tab or window flashes open and closes immediately.
- Nothing appears in the top-right download bubble.
- The entry silently gets stuck in the full Downloads manager (opera://downloads) without actually saving the file.
- The only workaround is to manually copy the link from opera://downloads and paste it into a new tab to force the "Save As" prompt to appear.
Disabling the built-in ad/tracker blocker or changing download prompt settings makes no difference. Reverting back to Opera 139 immediately fixes the issue on Linux as well. Please prioritize a fix for this in the next build, as core download functionality is currently broken across both Windows and Linux.
