Basically, useless. Shows the most visited sites, and asks for money.

Prompt when clicking on icon to add bookmark on Firefox
'e.tabs.captureVisibleTab is not a function'

Was surprised to find at one point that you need a premium membership to have custom images for your tile images. Not a fan. As for recently, the issue with imgur is frustrating, especially since the addon hasn't updated for firefox yet, and it's been a few days since they said it should automatically update. Did you only release this update to chrome??

New update puts a gigantic margin on top and on bottom, had to reconfigure the whole thing (UI update can make that happend, not mad about that...) and even zoom out to have a decent layout... i'm no web developer and even i could just press F12 and fix that by lowering the margins... not gonna install a css web modifier just for another extension tho... it's a shame because all looks kinda blury now with the zoom trick... please fix.
i'll try to live with the zoom trick, might get borded of it and just use a different home screen....

It is no longer possible to create new groups. Developer does not respond even after repeated requests, although I even have a paid account.

Suddenly became a paid app

没法导入浏览器的书签，没法搜索书签，一百多个书签你是打算让我一个一个导进去然后一个一个找么？

Cons:
- Bad privacy, grabs website logos online from a server and allows that server to track your IP, one's fav sites and how often one accesses them. This is not compliant to GDPR's data minimisation and data transparency principle. Better would be to store and load website images locally and not establish an online connection by default.
- Loses settings when cookies are deleted for privacy reasons
- Tracks usage by unique(!) User ID in Local Storage, a no-go!

Pros:
+ clean and lean look and feel of that addon which is why I tried it.
+ not bloated with lots of useless features which is also a plus.
+ It does its job (and works in FF 71, too)

It was great until today, when I launched my Firefox and saw, that all my deals had been deleted :((

How to change and delete thumbnail tabs, nowhere in the thumbnails there are settings buttons

not bad but "add to dial" button not working in ff67. edit: so far liking this one if anyone wants an alternative:

https://addons.mozilla.org/en-US/firefox/addon/yet-another-speed-dial/

Context menu for "Add to speed dial" doesn't work in firefox making this useless for me (its enabled in advanced options). Otherwise its a 5/5 for chromium browsers.

I have used this extension for years but recently there seems to be zero support. There is an annoying bug I see in this Firefox version which I have reported several times but have had no reply. So sad. I have never been a fan of the alternatives but I am actively testing them now.

This extension used to work seamlessly. Now it requires a google sign-in and doesn't load in new tabs. Very annoying and difficult to use in Firefox.

Could be very good, but is so bug ridden that after a few days I just had to uninstall it. The bugs:

1) Keeps showing the tour on every start in Private windows, tabs, or if you have deleted your cookies.
2) Randomly displays text info below the dials... which pushes the dials up under the group bar.
3) Randomly reverts to default settings on either all, or some of the options.
4) Randomly opens up as a blank page, yet the "moz-extension://cd47a81f..." still shows in the address bar.

I could list more issues. Note that this occurs on Linux, WIndows 7, and Windows 10. Real bugs. And lots of them. Developer: If you want people to pay for premium, at least make it stable. One should not have to reconfigure your extension on almost every use. And, it needs to work with ALL types of FF settings.

I've been a user of this extension in Chrome for quite a long time but the Firefox version is rather broken. Many functions do not work normally yet, e.g. custom CSS.

Not bad extension but it doesn't keep user settings. After restart firefox, it again shows the tour, and appearance preferences are resetting.

This would have been the perfect bookmarking addon provided it actually synced with a bookmark folder. Right now - you uninstall the addon and all your bookamarking efforts are just GONE.
Once it does sync with a bookmarking folder, 5 stars.
