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.

Tengo en cada tab una página a una emisora de radio, al usar OneTab se dejan de escuchar cada una de las emisoras en cada tab. No me sirve así

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.

"Bring All Tabs into OneTab" loses all your tabs from other windows and the developers have known the loss that occurs for many many months, if not years. Used to be My Favorite extension.

I installed it to help me manage my 50+ tabs that I have unloaded, then it proceeds to LOAD ALL OF THEM. To avoid crashing my computer, I had to close my browser, and when I re-open my browser, ALL MY TABS WERE GONE. YOU HAVE NO IDEA HOW MUCH FUCKING BACKTRACKING I HAVE TO DO.

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