Opera is shit :
i have windows10 pro 64bits up to date and 16go of ram
i had firefox open with 850 tabs open
chrome with 200 open tabs
then i opened opera
barely open ,all of my 300 open tabs were deleted at once!!!I lost everything!
and in the opera folder ,current session and last session have been reset,a big shit opéra
while this has happened to me several times with firefox in the past,but by going to the firefox folder,he always keeps a save of last session and i have always been able to recover all of my tabs!
but opéra won't have me anymore ,luckily there is a fabulous extension! : Tabs Backup & Restore
https://chrome.google.com/webstore/detail/tabs-backup-restore/dehocbglhkaogiljpihicakmlockmlgd
-to install it, you must first install this extension in opéra :
Install Chrome Extensions
https://addons.opera.com/fr/extensions/details/install-chrome-extensions/
then go to my link of Tabs Backup & Restore
and click on : add to opera
this extension is awesome it automatically saves open tabs a choice from 1mn to 4 hours!!! unfortunately it has not been updated since 2012 but it still works like a charm ! 🙂
