Greetings... I am a frequent user of multiple tabs whenever I use Firefox. As a result, the new Tab Groups feature interests me, primarily if it will help my to organize and manage my multiple open tabs. Initially, I have the following specific questions. Q: Is there a maximum quantity of tabs that a Tab Group can contain? Q: Is there a maximum quantity of Tab Groups that can be open at the same time? Q: Does the use of one or more Tab Group negatively affect the performance of my web browser? Q: Can a Tab Group be bookmarked? (Periodically, I need to bookmark a group of open tabs and I am currently able to do so by selecting all of the tabs then bookmarking them as a set.) Q: Does the new Tab Groups feature represent a way to reduce the number of open tabs that appear at the top of my web browser - basically, a way for multiple open tabs to occupy a smaller space versus scrolling them across the top of my web browser? Thank you very much for your feedback! Take care...
