Good Plugin.. But Rated 3 out of 5 stars

I have been using this plugin for since ever... But recently I notice when I have multiple display monitor setup, the tab preview pops up in the Primary screen only even if Firefox is running in secondary monitor. This is the reason I'll give 3 star for now. Otherwise I'd give 5 stars.

Please fix this ASAP.

Tab Preview opens on adifferent monitor Rated 3 out of 5 stars

I have a dual monitor setup and whenever i hover over a tab, the preview window appears on the second monitor, and not under the tab i'm on, as it should.

I really need this. But it stop working in Firefox Nightly. Hope this will be able to use again with the new WebExtensions API.

One of the add-ons that makes Firefox Rated 5 out of 5 stars

This is one of the add-ons that has set Firefox apart for all these years. I hope it makes it to Web Extensions but I fear it won't.

Awesome addon!
I really like how smooth the preview display is, and the granular control. Thank you very much for your effort.

この手のプレビュー機能は、リソース(CPU、RAM 負荷)を要求するうえに、しばしば、ブラウザを不調にさせるため、使用することを止めていました。

OK buggy and not reliable Rated 2 out of 5 stars

When it works, it works good. Often does not pop-up/show any preview.

Firefox 45 on Linux.

Great All-Around Utility Rated 5 out of 5 stars

Tab Scope is a great add-on that leaves little to be desired. Upon first installing the add-on, the ease with which one is able to navigate between their tabs is readily apparent. The features that come with the default installation are simple and intuitive and especially when one has many tabs open, Tab Scope helps tremendously. In addition, Tab Scope is very easy to customize. Simply visit about:addons, click on extensions, click on the options button next to Tab Scope and there are a variety of small features that users can modify to tune the add-on to their own personal preferences and style, ranging from the desired popup delay to the size of the popup displayed. The add-on works smoothly and features a nice balance between simple and customizable. I do not think that there is anything to improve upon.

Request: Mute Tab Button Rated 5 out of 5 stars

Hi , is it possible to add a mute button into the toolbar?

I've been using tab scope since forever , and it's a must have IMO , but i don't know where to reach the developer for a feature request.

Tab Mix Plus has this feature (through right-click) but i think it's a better experience on Tab Scope

Tab Scope 163 Rated 5 out of 5 stars

Ive loved this add on and used it for a long time, now, all of a sudden it is no good in FF43.0.1. I had it working yesterday, I took FF up to v47 but too many things got unverified or sometihng. so went back to 43 and tab scope isnt verified or something. I did a clean install, was working @FF v43 just hours ago. I am not sure what is wrong. i cant find any change log or older versions either. I do not think anything is wrong with TabScope just want it to work
I found that TabScope or something just got updated to v1.6.3. I was able to find a version history and reverted to the 1.6.2 version and all is well
I did not notice any update, just all of a sudden no more tab scope, after 8 or more yrs. I just got used to it being around. despite a pulldown tab showing up on the other monitor sometimes. I still love it. thanks.

Great and very useful Rated 5 out of 5 stars

Hi! It is a great and very useful add-on! Thanks for it!

Just a few words: IT IS TRICKY and embarrassing - when Firefox is projected onto a second screen (in case of dual monitors) the tab-preview appears on the primary monitor and unable to take any mouse action since its focus is on the secondary monitor.
How to deal with this issue, if I don't want to change the second (e.g. bigger auxiliary monitor) to be the primary monitor instead of the laptop monitor???

Good Rated 5 out of 5 stars

This is definitely useful. Let's you check on tabs without switching to them.

Only problem is that if you are "scoping" a tab, any keyboard shortcuts are disabled until you move out of the "preview mode".

Perfect Rated 5 out of 5 stars

I liked the idea of checking tabs without going in to it. This addon gave me that option ... but with more things like interacting with the tab without switching to it. This is perfect!
