I have 3 Mint systems (all running 18.3 64Bit) all running Opera Version: 62.0.3331.116. For some reason, when I ran updates the other day, the listed update wiped out all my settings on one of the systems. That system was like Opera was a fresh install. I lost all my settings etc... No problem, just copy the config file from one of the other 2 working systems, right? Wrong. I copied my /home/username/.config/opera from one of the other 2 working Opera installs, across the network to the suspect machine. I then replaced that Opera folder on the suspect machine with the entire .config/Opera folder from the working machine. But when I open Opera on the suspect machine, it still looks like a fresh install. Also, the panel shortcut I have for Opera no longer works on that machine.... like somehow Opera is now installed in a different location or something. I have to start Opera by going through the menu drop down instead. Is there another file/folder I need to replace, to make this suspect install recognize all my settings? I really dont want to go through the hassle of setting everything up again on the suspect machine. Thanks!

@burnout426 said in Opera Updates Change Mail Handler Preferences:

Goto the URL opera://settings/handlers and remove the mail.google.com email entry if it's there. That might stop it from happening again. Turn off "allow sites to ask..." to block all sites if you want.

The only thing at that URL, was "Allow sites to ask to become default handlers for protocols (recommended)". I turned it off. Although, that wasnt the problem, as I wasnt being asked anything about the mail preferences. Im just sick of having to fix Opera, after they update it and break it.

Well, I thought this was fixed, as a previous update to Opera did not change the mail handler settings to Opera itself. Then, updated Opera again his morning to Version:62.0.3331.18, and low and behold..... the first email link I click on, tries to handle it through Opera, asking for my gmail login information. This is getting ridiculous. Now, every time I update Opera, I have to fix the stupid video playback issue, and change my mail handler setting back to Thunderbird!

Edit: Even after changing the mail handler preference back to Thunderbird, it still tries to handle it in Opera. When this first started, I could change the preference back to Thunderbird, close Opera and open it again, and it worked properly by opening a new email in Thunderbird, when clicking on an email link. This time, it wont. It shows Thunderbird as my preferred application for mail, but when I click on an email link in Opera, it tries to handle it in Opera through a gmail account online. I logged out of/back into Mint.... still wrong. I rebooted the system.... still wrong. The preferences still show Thunderbird, but it still tries to handle it in Opera. Im about ready to go back to Firefox and be done with these aggravations.

Edit #2: It is now working again. Simply going through the steps above, did not rectify the situation. For grins and giggles, I changed the mail handler to Kmail. Shut down Opera, and opened it back up. Then I changed it to Thunderbird, shut down Opera, and opened it back up.... and NOW it finally is working correctly!

It does here also, after I changed it back via default programs

$ xdg-mime query default x-scheme-handler/mailto
thunderbird.desktop

Telling us what I already stated, that Thunderbird was the mail handler

And what does this gio binary package do, and exactly why do I need it?

@jimunderscorep "Command not found". I have already changed the default back to Thunderbird, in preferred applications, and it works. This is 2nd or 3rd time in a row, that updating Opera, has changed the default/preferred mail handler to itself. The only way I knew it had changed the default from Thunderbird, was clicking on email links in Opera, did nothing. Once I figured out what it was, and changed it back to Thunderbird as default, it was fine.... till the next update.

@jimunderscorep ....... Regular

The last couple times Opera has updated, it has changed my email handler preference to Opera, from Thunderbird. Any way to prevent this? Running Mint 18.3 64bit with 4.4.0-148 kernel, and Opera Version:60.0.3255.151
