I'm looking for a replacement for 'session manager' in Firefox Quantum and I've downloaded this addon among others to test it. The main problem for me is the lack of search functionality. I have read the reviews and the developer's response to this problem is, basically, to laugh at the suggestion and say that nobody has asked for it. I have not bothered asking for it because I have discarded the addon. Each one uses the addons in a particular, sometimes unique way. I read with perplexity the response to a user about his suggestion of a search engine: the developer brags about having 300 tabs (or 1000) in a window and never having needed a search functionality. The interesting thing about working as a developer is that your code is thought for something and users end up using it for what they really need. The more users, the more different uses. I do not think it's a good idea to mock the suggestions of your users. Or brag about having 300 or 1000 tabs in a window.
