Without any difference in functionality the grid view doesn't make much sense to me. For a long time Firefox was the preferred browser on my phone, mainly because it was the only one that supported manual tab reordering. The fact is that I often have a lot of Web pages open in tabs, and I plan to read them later. With Firefox I could quickly set the priority of reading, moving tabs up or down. Suddenly Mozilla made the tabs unmovable and introduced collections instead. Collections are convenient, but don’t replace manual tab reordering. They are great for routine tasks. But on phones, the vast majority of routine tasks are performed by their own applications, so, collections can only be useful for news and forums. However, even while reading the news, I open several tabs that I often need to rearrange. Thus, Firefox became much less attractive to me. Around the same time, Google’s Chrome made tabs movable and even introduced groups of tabs to make browsing more convenient. I recently realized that I now prefer Chrome. I only open Firefox when I need to listen to music videos in background or access my bookmarks and Firefox accounts. Will Mozilla team ever again return manual change the order of tabs?
