Can you super dooper computer experts tell me how to create a file that holds all of my customizing Opera that could be used to change the new install's customizing to the way I make it after a new install..?

if the sync doesn't work for you, I would just compress the C:\Users\<user>\AppData\Roaming\Opera Software\Opera Stable folder with 7-zip or so, and then decompress it.

Thanks for your keen advice.. I'm working on it..

Too bad that the new Opera version won't run in this Mint 19... I love this Opera browser.. It's honest and honorable...

I had to reinstall the OS last night yet again..

So, the whole point of this thread was: 'Can there be a file we can save of our customizations to Opera, so we can simply apply it to the next Opera install, without needing to run through all the configuring in Opera's Settings..?

I think I might have a solution to this problem..
Microsoft has purchased much of Linux world to meticulously kill Linux, the competition, to make Windows be the only operating system that works in phones and computer on the Web, to meticulously destroy Linux, the Poor peoples computers and phones OS.. It's all bout making lots more money...
I had to dump Linux Mint 20 because I found it too buggy and brutal, with too much Microsoft meddling in it..
I dropped back to Linux Mint 19.3.. It's not buggy.. Maybe you can get a clean ISO from Older Versions...
In a new double encrypted install of LM 19.3 I don't do any of the updates, None what so ever.. I install without the Net-connection, is absolutely crucial.. I boycott All the updates.. Microsoft now owns Canonical.. It seems they've put lots of nasty stuff and glitches in the updates to make people start to hate Linux.. The computer is working fine without any of the updates..
At first boot I run Synaptic to completely uninstall: Firefox, Hexchat, Rsync, Transmission, LibreOffice, and everything Bluetooth.. then reboot, change Sources to a trusted university, add BleachBit, and run it, reboot, and add Opera, and disable updates, and add sound codexcs.. Sometimes I even uninstall the Updater.. Then go to extensions, and add Transparent Panel Extension.. Then get a freebie Protonmail email account...
I never ever use an in OS email system like Thunderbird.. Thunderbird is buggie and bad.. This way I can't ever lose any of my email data from a hack-attack that destroys the OS.. Protonmail is super secure, the best of the best.. Protonmail people are as honest and honorable as it gets...

This procedure might stop your computer memory problem..

I always have my precious data stored in seven external hard drives.. This way I can't ever lose my data.. One external hard drive is stored at a relatives, in his fireproof/waterproof floor safe in another city... Do so get an external hard drive as CD's and Flash Drives are not reliable as long term backups... I prefer Toshiba external hard drives.. They last..
Never ever bump an external hard drive while its in operation.. It's best to tape them to the desk.. Never ever run an external hard drive while the machine is connected to the Net... Make your backups today.. Be safe not sorry and sad...

For personal reasons I must reinstall this Linux OS every week.. Not a serious problem as it takes only two hours to complete a customized new install of LinuxMint 19.3..

It would be nice if there was a way to make a file of all my customizations to Opera, so for new installs of the OS I could simply add that file to the new Opera, and the original customizing gets all done in seconds..

Gmail login page is eye-stinging blinding at night.. How can I make it be a dark royal blue?
