Firefox 技術支援討論區

I asked such a question the day before yesterday, but none answered me I still use window 7 32 bit and I never want to update The new version ( V 98.01 ) is not compatible with Window 7 A black screen is shown just I open the Firefox browser I thought it is virus, but it is not so. Now I am sure of the problem I uninstalled the new version and changed for an old version ( V 80.01 ) and the black screen is never shown The black screen which I complain about= crashing of the browser because it is not covenant to Window 7

2- I changed the update to  (   Check for updates but let you choose to install them )  and the problem is ended but a message about updating still appears in the right corner  need me close each time. 

How can I get rid finally from update message in the toolbar ? In V 80.01 there is no choice ( never check for update )

Firefox used to have an option to put tabs back under the address bar, it is missing. I don't want to mess with custom css files every update when mozilla breaks things again.

I paid Firefox $28 for unmarked videos. Now the mark, the stamp in the corner of the video, is back. I would like my money back or the non-stamped videos back. Who do I see about that?

I DID NOT FORGET MY PASSWORD AND I HAVE ACCESS TO MY EMAIL BUT MY SYNC INFO IS GONE. I have been using a live usb Linux system & sometimes 3 times a day other times 4 or6 days solid i boot i get online ten open Firefox activate my toolbar menu then open tools then sign in to Firefox and sync normal i get all my add-ons but last week i did this and got nothing, blank. FF. ACCEPTED MY PASSWORD but acts like i got nothing to sync and i have it on my android and wen i sync my phone nothing its lie 2 different accounts but i checked everything is right. i have read all the on line help but i dont see anything. im sorry but when i forget a password or cant get in to my email i do not try to get help i just deal with it and fix it. the only reason im trying to get help is i have relied on this service fo a long time and my bookmarks and most of my passwords i dont know. i know i can change them, and i know how and i have secondary emails and so on but my problem is why out of the blue fire fox has nothing to sync for me? my name is ronnie mattix my email is [email address] and i know my Firefox password but other than that i would have to change every thing. and i have not changed my Firefox password for 6 months or so. so what should i do? thank you for helping rm
