It's wiped every tab on the program about 4 times now.

Thanks for giving me another reason to start using Arc. This add-on may work fine for a few months, but then something breaks it beyond recovery. After the latest updates:
- All the tabs got deleted, and can't be restored from the backup
- Sometimes it freezes on the progress icon, so you can't interact with it

This is not the first time this has happened.

lately its stopped working and it crashes upon restoring tabs

Works great on my Windows 11 laptop, but recently stopped working on my Linux Mint laptop. On Mint, when the browser is reopened all tabs are immediately opened in the same group, regardless of what group it's supposed to be in. I have emailed the .json bug report to the dev, hopefully it gets fixed soon.

it would a good extension if my tabs didn't keep disappearing.

Simple, effective, looks nice. I LOVE this addon!

Add on works great! Makes my user experience significantly better. One issue though: Please add support for using keys F13-24 for keyboard shortcuts. They are not standard, but they are defined for all major operating systems and I use them in my custom keymap, would be extremely useful to be able to bind shortcuts using them. Currently, firefox lets you assign the keys to the functions, but attempting to use the bound hotkeys does not do anything. Thanks!

Completely broken at the moment, it is not even possible to load old backups manually. If it works like the last few months then great extension.

Incredible addon !! Simple UI , keybinds , saves your tabs progress into specific groups ( works like an autosave ) , open source, there is backup , you can open groups in different windows. Navigation may be troublesome.

It is incredible that Mozilla still recommends this addon. It used to work great, but since Firefox 132 it has some major issues. For me, first time it lost all groups when I installed Firefox 132 (31 Oct 2024). However, back then I managed to restore them via the addon’s setting. Then it lost them again on 10 Jan 2025 when I installed Firefox 134.

Now as others have reported, with Firefox 135, it is impossible to restore the groups via the addon’s settings. When you try to restore from a backup file, it simply closes the browser and when you open the browser again the groups are not there.

Do not waste your time with this addon.

What's going on, please provide a patch. It's very inconvenient.

Excellent
