I just installed the latest Version of Firefox 101.0 for Windows 10. Then when I tried to download a pdf file from my yahoo mail I received the following message: "Problem loading page" Firefox Can’t Open This Page To protect your security, dl-mail.ymail.com will not allow Firefox to display the page if another site has embedded it. To see this page, you need to open it in a new window. Learn more… Open Site in New Window Report errors like this to help Mozilla identify and block malicious sites

So, in order to open the page I have to press "Open Site in New Window"

Please advice why happened this issue and how can be fixed.

Hello,

I've been trying to open Firefox and receiving the error "Firefox is already running, but is not responding. The old Firefox process must be closed to open a new window.

I've checked the task manager, restarted the computer, re-installed, refreshed and nothing helps, still getting the same error. Any suggestions? Thank you

Whenever I try to download something off my google drive, text pops up in the bottom left corner, but then nothing happens. It works just fine on microsoft edge, so I think its a firefox issue and not a google drive issue. I tried refreshing my browser, deleting my cookies, updating my browser, turning off enhanced tracking protection, and anything else I could think of. Please help.

Win10 with what was Firefox 89. I had already disabled the Proton UI on this installation, because it is horrible. Today Firefox decided to update to version 91. All of the Proton UI junk is back. I tried disabling it again, but nothing worked. Doing a web search, it appears that Mozilla has disabled the ability to turn off Proton.

I then set about to rollback the installation back to version 89. I found a Mozilla link on this, went to their ftp server and downloaded the installation files for the last version of 89. The installation went normally, but when I opened Firefox afterwards, a little box popped up saying something to the effect of "To keep your History and Bookmarks from possibly being corrupted, Firefox must create new user profile." I exited out of this and Firefox didn't start. I attempted to restart Firefox again and the same box popped up again. The only way to get past it was to click the accept button.

I did so and Firefox started. This was clearly not version 89. As the UI is junk, it took several minutes to find out that this was now the latest version of 92!!!! I'm absolutely positive that I downloaded the correct file. When I look through the update history, it doesn't even show todays version 89 installation as happening. What a piece of junk.

I then spent 20 minutes figuring out how to revert back to my user profile, not the new one that it had created for me. I then did some research on what had happened. Well it turns out that you can't actually rollback Firefox, despite what Mozilla says. For a while they have added "downgrade protection" which automatically creates the new user profile and stops your old profile from being accessed by it. So unless you want to figure out how to spend a hundred hours reconstructing bookmarks, passwords, settings, etc. it actually isn't possible to rollback Firefox. Doesn't this violate some Microsoft rules about being able to uninstall versions of software from within Windows? If you try to do this with Firefox and go back to a previous version it blows everything up.

Does anyone know how to actually rollback Firefox to a previous version, so that Proton can be disabled?

From a Mozilla Support page, " Firefox lets you import login information from a .csv (##..##) file. This feature is available starting in Firefox Version 80." I have the .csv file for my logins and passwords thru the export function. I can not get the drop down menu where I can select the "import from a file..." per the instruction in the support example because I am running Version 79. Many attempts to update to the latest version stops at 79. My help page for version states that I have the latest update --v79. SO--- any suggestions as to were I can go to download version 80. I am trying to transfer my logins from laptop 1 to laptop 2 without going thru the laborious task of entering each login by hand.
