I appreciate you taking the time to leave a review, I'm glad this extension is meeting your needs!

Sorry you had a bad experience with this extension. The extension was definitely designed to persist tabs after computer shutdown. It uses `localStorage` (https://developer.mozilla.org/en-US/docs/Web/API/Web_Storage_API) to save URLs for each tab. This is designed to "persist even when the browser is closed and reopened." This storage can be cleared through the browser settings or through another Javascript extension.

Feel free to file an issue (https://github.com/avbhatt/tabs/issues). If you include some more information with your issue I can try and replicate the issue on my end.

Sorry that you lost your tabs. This extension uses `localStorage` (https://developer.mozilla.org/en-US/docs/Web/API/Web_Storage_API) to save URLs for each tab. It is possible that this got cleared somehow. According to the linked docs, `localStorage`: "Stores data with no expiration date, and gets cleared only through JavaScript, or clearing the Browser cache / Locally Stored Data"

If you submit an issue (https://github.com/avbhatt/tabs/issues) with some more information about your Firefox configuration, especially any other extensions that you have installed that interact with `localStorage` I can try and replicate this problem on my end.

Another thing you can look for is the "Saved!" flash after clicking the "Save" button. This means that each tab has been successfully saved. For additional confirmation that tabs have been saved, try clicking "Restore" right after saving. This will open a window with a list of your tabs.

Wow, I really appreciate this. Thanks for reviewing. I'm glad it's meeting your needs. Please let me know either here or on GitHub (https://github.com/avbhatt/tabs/issues) if there is any issue or other feature requests you might have.

Thanks for the review! I haven't experimented with one extension having multiple toolbar buttons, but I'll look into it for sure.

Thanks for the feedback! Your use case of saving a window's worth of tabs makes a lot of sense. In the new update of this extension, tabs are grouped by what window they were in and you have the option of restoring to your active window or a brand new window. I'd love to hear your thoughts on the update if you get a chance. Thanks again for the review.

Edit:
I really appreciate you taking the time to try this extension again. I can't seem to replicate the problem of improper rendering on my machine. If you have time, please file an issue (https://github.com/avbhatt/tabs/issues) with your Firefox configuration. In terms of "Save" feedback, there should be a flash to "Saved!" after clicking.

Thanks for your review! Visual confirmation is a great idea, in the new update of this extension I added some feedback on clicking the "Save" button. Just in case you need to confirm, clicking the restore button will show the list of saved tabs.

Thanks for the review! I hear you about the favicons, but I haven't figured out a consistent way to grab them from websites (not all websites have them at /favicon.ico). If you have any ideas, please share them with me here or on github.
I have tried making the extension more aesthetically pleasing in other areas and would love to hear what you think about the new changes.

Thanks for the review! I will look into what is causing the new window to open up, potentially the list is not being cleared properly on save. The extension is designed to save links from all open tabs of all non-private windows into the list. When "Restore All" is clicked, the saved links are restored in newly created windows.

For example, if when you hit save you had the following windows/tabs:
- Window 1: Tab A, B, C
- Window 2: Tab D, E, F

After closing and reopening your browser you already have one window open and potentially multiple tabs. Clicking "Restore All" will result in the following:
- Window 1: Tab X, Y, Z, ... [This is the state of your current window; it should be unchanged from before clicking "Restore All"
- Window 2: Tab A, B, C
- Window 3: Tab D, E, F

Do you think this is a good way to tackle preserving Window organization? Other options include appending the tabs of the first saved window (A, B, C) to the current window and only creating a new window for the subsequent saved windows.

Please submit a github issue with steps to reproduce this bug if you can: https://github.com/avbhatt/tabs/issues

I think your idea to prompt to save tabs on close is great. I will look into that for sure. In an effort to make this extension as non-intrusive as possible I may have to include some sort of options page to configure this. If you would like to submit a feature request, please do so on the same github issues page: https://github.com/avbhatt/tabs/issues

Again, thank you for the feedback. I truly appreciate it.

Thanks for reviewing, I really appreciate the feedback. I will try to add the option to save from all windows as soon as I can.
Would you like the tabs to be restored to the window they were saved from, or for all of the tabs to be restored to a single window?
