Hi, we've checked the Firefox source code, and Firefox will not evict any OneTab data due to low disk space.

The problem is probably that you are running some kind of privacy cleaner or system cleaner software which is trying to evict Firefox data, and is wiping extension data (including OneTab) at the same time. 'BleachBit' and 'Advanced SystemCare' are known to do this.

Hi, you can do what you're describing.

By default, if you use Firefox tab groups, then each tab group will be stored separately, and can be restored separately.

If you want to store a whole window full of tab groups, and have the entire window restore at once with all of the tab groups inside, then you can do this by going to OneTab Options and choosing the "Send the current window to OneTab, including all tabs and tab groups" option.

I'm sorry this happened. The problem isn't Firefox, it's software such as privacy cleaners, or disk corruptions, that can corrupt Firefox's data stores.

The solution is to either ensure that your regular backup software (that keeps your files safe) also backs up your Firefox profile folder, or to use our upcoming encrypted cloud sync and backup feature.

Hi, I'm sorry you lost your tabs.

What happened was not a bug in OneTab. Firefox profiles can become corrupted, and then there is nothing we can do on our end.

Thanks :)

Hi, I'm sorry this happened. It's definitely not a bug in our code, though. Something is wiping Firefox's internal storage - it's pretty much impossible for us to accidentally write code that would suddenly just wipe the entire contents of the storage and then delete the entire OneTab database after that.

Some "privacy cleaner" software will wipe Firefox data, or it could have been a crash causing a disk write error that corrupted the storage areas. Firefox's "Refresh" feature also wipes clean the extension storage. Being low on disk space when the browser is trying to write to its databases can also cause corruption.

Thanks, Rio :) We'll be implementing an undo feature in the future, especially to be able to undo move operations. Please also contact us at one-tab.com/feedback as we'd love to get more detail on the quick actions you're referring to so we can ensure we're building the right thing.

We are working on cloud sync to ensure you can keep the data safe.

Hi, yes we'll fix the issue that defaulted the OneTab tab to be pinned in the upcoming update

Thanks, Dola :)

Hi, do you remember recently being asked if you want to "Refresh Firefox"? This is a prompt shown to you when you upgrade to a new Firefox version (there is a new Firefox version released every month). This feature, confusingly, wipes clean all add-on storage including OneTab's storage. If Firefox ever gets a disk corruption, that could also cause data loss.

I'm very sorry this happened to you. We're working on cloud sync so in the future this can't happen.
