Back up your Opera files
It is recommended that you regularly back up your most important Opera files. Opera recommends backing up your files before upgrading, as well.
Locating your files is the first step. Go to About Opera, or go to
opera:about/ to find the exact paths for your profile and data folders.
Not all files and folders listed below will be relevant for all users.
Files to back up
||Your bookmarks’ metadata, such as name and location|
||Your bookmarks’ associated thumbnail images|
||Your cookies (may not be essential, but you’ll need to sign back in to web services if deleted)|
||Data about your current browsing session including open tabs, location on the page, form data, etc.|
||Cookies associated with your installed extensions, such as location data for a weather extension|
||Favicons associated with pages added to your bookmarks bar|
||Your browsing history|
||Data associated with sites you visit that use Mozilla’s IndexedDB API, a structured database indexing system|
||Your internal browser preferences, such as the last-seen version number and download location|
||Your saved, encrypted passwords readable only on the machine that created them|
||Your current browsing preferences and information about your profile|
||The location of links you’ve already visited used by Opera to display them as visited|
||Your autofill and other data imported from IE7|
Folders to back up

If Opera crashes
There are a few steps you can take to help restore your Opera browser to working order. Even if the steps here help you, sending Opera a crashlog report, including details of what you were doing when Opera froze, helps us fix future browsers. This way we can help others that may experience the same problem.
If Opera crashes, a dialog displays and asks if you want to send a report about the problem. The report includes technical details of the crash and any relevant comments you wish to include. This information helps make Opera even more stable and reliable. Provide some details about what you were doing with the browser when it crashed into the text field, then click Send Report.
If restarting the browser application does not solve the problem, you may want to download and install a clean version. We recommend that you back up your Opera files before clean installing.
To clean install Opera:
- Uninstall the Opera application from your computer.
- Delete your Opera profile data.
- Download the latest version of Opera.
- Install your new, clean version.
If a clean install solves the issue, you can copy over your backed up files into your new Opera profile. If this causes Opera to crash again, remove your browsing data.
If Opera still crashes, submit a bug report. Compress your Opera profile folder using .zip, .rar, or 7zip, and send it along with your report. If you find the file that makes Opera crash, specify this in the bug report.
