3 suggestions that I think would make it even better:
1. Export as json/csv - Would be useful so that I don't have to keep a .txt file laying around with the urls and instead have a formatted json/csv file.
2. A way to search through the links on the OneTab page, currently I use ctrl+f to do this, but I think it would look nicer if it had its own search or if when you searched it narrowed the results down from all your tabs so there isn't a bunch to look at.
3. A more secure way to save OneTab tab data that isn't exporting/importing them. I'm not sure how this could be done, but according to dozens of reviews, their tab data was lost for seemingly dumb reasons that shouldn't occur.

Awesome add-on. Simple and most convenient.

Just one little thing, when exporting/importing the group names are lost.

Good until Firefox updates or your computer crashes--then say goodbye to your tab hoard! They will be permanently lost.

AVOID IT! All this extension will mostly end up doing is causing loss. It is known to randomly or unanticipatedly lose all or data. You have been warned.

This extension did not do what it says. Took control of my browser and would not give back control until I uninstalled it. It still did not uninstall completely and has its own icon in the top left corner of my browser instead of Firefox icon. Hosed my tabs and lost my data. Had to restore my session by restoring one tab at a time from my history. TOTAL GARBAGE

This add-on is very useful and work as intended most of the time. You just have to be very mindful to export your tabs for backup every now and then, so you don't lose them. If you reinstall OneTab or your browser, you will lose all your saved tabs. So use the "Export / Import URLs" feature. The app lack important features, so I withdrew one star.

it works until it doesn't. And when it doesn't, it makes you lose all the tabs that you just saved. I lost over 50+ tabs because it just stop working.

I sent them this feedback:
"click the OneTab icon to convert all of your tabs into a list. " please make this disableable. I left-clicked the icon accidentally and lost a ton of intra-tab-history.

One of my favorite extensions for Firefox. It has its limitations but suits my use cases just fine. If there was one thing I would wish for it is the ability to intelligently sort and categorize tabs.

besoin de trier (2798 onglets) : pas trouvé de solution dans Onetab, impossible de fw les url à Pocket. :/

really enjoy this extension, wanted to request you add an option to make it so that when you left click the extension it only sends the current tab to onetab. would REALLY appreciate it!

Was incredibly satisfied with this add-on, as it does essentially do what it says, sends all your tabs to a single directory, thus freeing up your firefox resources, *was* satisfied that is until I learned it apparently automatically deletes your tab groups after a certain period of time. Finally had some free time to poke through all the various articles and pages I'd set aside for future viewing, only to find that OneTab had deleted all but my most recent stored tabs which is explained nowhere in the addon's documentation, nor are there settings to adjust when these deletions occur. Three stars because it does indeed do what it says initially, but be sure to return to your stored tabs promptly and back up whatever you want to keep for future perusal because you never know when it may be lost. Very disappointed with this.
