Many thanks, @burnout426. I followed your instructions, but clearly I had made a mistake by closing Opera early on after I noticed the mistake, and while I had a Tabs_ file from the day before the crash, I only had a Session_ file from afterward, so those previous windows and tabs are gone. Thanks for the tip on backing up. I'm moving to a new computer, and will need to reestablish as many of those windows and tabs from History as I can or wish to, and then copy or sync the necessary files to reproduce that on the new system.

OK, WRT "technical stuff": I located the folder AppData\Roaming\Opera Software\Opera Stable. There are a lot of files stored there, for instance one called Tabs_13320265919185108 which does seem to have some information about sites I browsed yesterday. Can anyone point me to any file there that might be holding the list of windows and tabs I had open yesterday, and which Opera might be able to use to reopen them?

@bfallona, thanks. But I presume it can't retroactively fix the current problem, only solve future ones?

I have been running Opera v. 94 with a large number of open windows and a very large number of open tabs. When I opened one new tab (it was an Evernote note opened from an on-screen notification), Opera crashed out entirely. After a minute a new Opera window opened with (for some reason) an Evernote help page I did not have open. In Task Manager, all my previous Opera processes (37 of them) still seemed to be open.
I waited several more minutes, hoping the closed windows would reopen, but they never did. Perhaps unwisely, I closed the one open window, then restarted Opera. That window reopened, as did all 37 processes, but no other windows or tabs.
Is there any way to reopen previously open windows and tabs after a crash like this? I can't find any way to do it, other than by opening one new window at a time and going back through the history reopening every tab one by one. I'm willing to try "technical stuff" if necessary. TIA for any help.
EDIT: In previous crash situations, I have seen Opera automatically reopen a comparable number of windows and tabs. I don't know why that didn't happen this time.

@donq said in Extensions disappearing from toolbar:

@davidr
If you click extensions button (wire cube) on toolbar, do you see your extension? If yes, then you can pin it there.

Sorry for the delay. Many thanks! That worked. I had no idea that option was there. I never did it before, and I've always had this extension on the toolbar. The Extensions page does not show the pinning option, and that was what appeared after I (re)installed the extension. So it feels like something changed without notice. IAC, it's working now, and all is well.

I just installed it. I didn't see an option to pin it to the toolbar. And again, I've had it working for a couple of years, and it just suddenly disappeared.

@leocg , yes it is there (Ctrl+Shift+E). Where it is missing is in the toolbar. (Which I just tried to upload a screenshot of, but I get a "Something went wrong while parsing server response" error message, so you'll have to take my word for that.) This extension, when you click its icon, runs an Evernote service to clip the current Web page (with various options) to an Evernote note. It has been working fine until it disappeared today.

I only use a few extensions in Opera (v. 87.0.4390.45 under Windows 7). One of them is DuckDuckGo. Recently I noticed that it was just gone from the toolbar. I managed to do something--probably disabling it and re-enabling--that brought it back.

Then today it was the Evernote Web Clipper that was gone. As with DDG, it showed up in the Manage Extensions page as being installed, but it wasn't available. Weirdly, when I clicked the Remove button, the Evernote icon popped out on the toolbar with a dialogue asking if I really wanted to remove it!! So I removed it and reinstalled it. But its icon still doesn't appear in the toolbar. The right-click/context menu entry for Evernote Web Clipper is present, but it doesn't offer all the options of the toolbar extension icon.

Anything else I can try? I've used Opera for at least 30 years, and have preferred it over all other browsers. But messing up Evernote is a deal-breaker. What's going on?

@ravenplume
This bug has now been fixed in Opera 81 Developer.
DNA-95481 Address bar disabled after changing win7 visual effects.

Do you know about how long it usually takes for a developer version to become public?

@gkaczmarek said in Opera 79 Stable:

The address bar bug was reported as DNA-95481. Thanks a lot to all of you that provided us with information that helped us track it down

Thanks, that's great to hear! Looking forward to the fix.
