Firefox on my mac has been acting buggy lately. The last time I quit and reopened it, all of my windows and tabs were gone. there is no restore previous session available and the recently closed tabs and windows options are grayed out. How can I restore?

Have a look at this thread. This process on a mac will be interesting to see for some reason. https://support.mozilla.org/en-US/questions/1509748#answer-1752029

Thanks for the reply and assistance. I believe I solved the problem by going into Time Machine and copying my Profile file from a time before the problem began and used it to create a new profile. It seems like I replaced the specific file you are recommending in your post along with everything else. It got the job done.
