Facil de usar, estable y simple; cuando tengo demasiadas pestañas aun por visitar, le doy a OneTab y quedan todas guardadas en un listado diferenciado y accesible. Tambien he organizado las guardadas poniendole nombre a cada grupo y es super util.

Useful! I can manage tabs closed by group.

Very useful! Thank you for making this tool. I find it very convenient and helpful in my workflow. I've been using it for several months without any issues so it has been a reliable experience.

I'm currently working with an HP Omen desktop running Win 10 Home version with 8 GB's of RAM. I use One Tab in conjunction with MemInfo from Carthago Software. MemInfo is a fairly simple memory monitoring and cleaning app. Every once in a while one or more Firefox tabs goes "runaway" and gobbles up (as an example) 3.23 GB's of RAM. This usually happens after having multiple tabs open for lengthy periods of time. MemInfo allows me to free up the memory from the offending tab(s) individually. Then along came One Tab - this extension allows me to click on it's funnel icon, wait a few seconds (usually less than a minute) for all the RAM used by the tabs to free up. When I "Restore All" the tabs come back with their usual and customary maximum of two or three hundred MB's of RAM use. I do like One Tab. I use One Tab and MemInfo as complementary programs. Each has their unique uses, but both are designed to cut down on RAM usage. Perhaps, one bright sunny day, Mozilla will fix that little problem Firefox has with runaway tabs turning into RAMsuckers. Until that day arrives One Tab and MemInfo will keep me going.

the REALLY BEST ++ WORTHY one for 2 years !!!!
