hi my email: [email removed from public] i transfered firfox open tabs( i have android phone) from my phone to pc firefox 3 months ago. i collected them a long time and saved them in a folder with name '''mobile bookmark '''in my pc and then i cleaned all firefox data on my phone to speed up it . today i referred to see the bookmarks in my pc, the folder - mobile bookmark- was there but was empty. i searched net and read some suggestion as yours : https://support.mozilla.org/en-US/kb/recover-user-data-missing-after-firefox-update but i can not see my bookmark . how can i do now? do you have any suggestion?
