@querenciaa I don't know about the existence of such feature. You can backup the Extensions folder and use it to install your extensions in the new Opera installation, manually.
Once you've got 8-10 tabs open, you run out of empty space. Same issue with Opera One.
I'd love to switch back to either Opera GX or Opera One, but this is a dealbreaker, I've used this feature since Opera 9 during the days it used the Presto Engine instead of Chromium.
@puddinpop4241 Generally you should never run a browser in Admin mode. Some of the browser's settings, history and cache will be saved as Admin-mode files, meaning your regular account will not be able to edit or delete them.
@rezeroenthusiast Check the mod's documentation: Mod developers may offer information about known bugs and fixes in their documentation. Look for mentions of the missing clicking sound and possible remedies.
Contact the mod developer. If the documentation doesn't help, consider contacting the mod developer directly. They may be aware of the problem and have a solution or advise more troubleshooting procedures.
Check mod compatibility: If you're using numerous mods, make sure they're compatible with one another. Conflicting modifications can also result in unforeseen difficulties, such as missing audio. Disable other modifications momentarily to check if the clicking sound reappears.
