I find the warning messages too intrusive in the "Suggest" mode; I suggest greying out the new tab buttons when the tab limit is reached rather than the current warning message system, or alternatively, displaying a non-intrusive popup reminder that can be clicked on for the tab list, or simply ignored so that it does not disrupt your work in progress. Rated 2 out of 5 stars

I'm in the same situation as kinecticrob. I like to have ~200 tabs open but would like to use this extension to prevent me reaching 900 tabs and it all becoming unmanageable. The "Suggest" option is just about satisfactory for what I'm looking for, although I think it needs major improvements. I suggest please that the warning message only comes up every time you open a new tab (and NOT every time a tab reloads, or you click on a link in the tab), to prevent it becoming too much of an annoyance, and effectively "bricking" FireFox. The developer says that you can carry on working with the "Suggest" option; this is not the case; it effectively still forces you to close tabs i.e. it's too intrusive to be just a reminder, because the warning message comes up again whenever you click on any link on the page. Also if you open tabs in quick sussesion (i.e. through a session resore), you shouldn't get 200 warning messages; that's just ridiculous; add a "do this to all" tick box to the warning box please.But the functionality I'm really looking for is one like on my iPhone 3GS. On the 3GS, the "new window/tab" option greys out when you reach the maximum tab limit (on the phone it's 8). I love this system, because it is much, much less irritating than the warning message approach this addon takes.The thing I do find annoying on the iPhone though is that if a link opens automatically in a new tab it overwrites the oldest tab. Instead of that with this addon I'd prefer it to just open in a new tab (i.e. temporarily raising the tab limit for just these "automatically opening in new tab" type tabs, but not allow further navigation in these tabs until you're once again on or below the tab limit - not using an intrusive warning message, just display a notice as a popup like when Firefox asks if you want it to remember a password for you). I know the iPhone just has the system due to technological limitations, but I really like the system and think that it would apply well to the users of the "Suggest" feature of this addon.This addon barely gives me what I require, but I could not browse without it. So I sincerely thank the developer for developing the addon, but I'm hoping please for major improvements in future updates. EDIT: Since editing this review a number of times, I have a different, simpler suggestion. In the "Suggest" mode, just make the warning message a non-intrusive popup (that you can CHOOSE to click on to display the tabs list) that goes away after a few seconds (or perhaps when you click on anything but it), so you can just carry on working. That way, you still are reminded that you have too many tabs open, but it doesn't disrupt your train of thought and work in progress.Anyone else have any suggestions to avoid having intrusive popups? Any solution without intrusive popups in the "Suggest" mode would be my perfect reminder system. Thanks again to the developer for creating this addon that's essential for those who have the tendency to open tabs at a faster rate than closing them without thinking about it.

This review is for a previous version of the add-on (4.27.1-signed.1-signed).
