I've got an old Windows XP computer running version 52.9.0. I'm trying to sign in to Sync (so I can sync with my new Windows 10 computer) but when I try on the old machine I get this error message:

Blocked by Content Security Policy

This page has a content security policy that prevents it from being loaded in this way.

Firefox prevented this page from loading in this way because the page has a content security policy that disallows it.

I've signed in on the new computer, not that it matters.

Is the any way I can connect to Sync?

For many years I use Firefox 52.9.0esr on my WinXP computer. And for even more years I have been struggling unsuccessfully with the following problem.

Under "C:\Documents and Settings\<username>\Local Settings\Application Data\Mozilla\Firefox\Profiles\2b9qepw7.default-1469870616368\cache2" there is a folder named "entries", that is constantly inflating! It is now 49.5 GB huge! I can not delete it. Deleting process does start, but doesn’t continue even for a bit or finishes ever. I’ve tried to delete the cache via Firefox preferences unsuccessfully. Even manually via Windows Explorer, even in safe mode (F8 when the computer starts), even with TotalCommander. The folder’s size just suddenly changes to zero when I click on it, but not the real space it’s occupying on my hard drive. I even uninstalled my antivirus and tried all the methods again – to no success…

I have added a video of what happens on my drive if I click on this folder in low resolution: https://drive.google.com/file/d/1E_gqf4s31m7Gr7taW5iUOUzkwe8Oi7iT/view?usp=drivesdk In high resolution: https://drive.google.com/file/d/1EaLROHC2p510CvP24nO83wplEkaAgrA9/view?usp=drivesdk

Please help me to solve this problem!

Thank you very much in advance!

Subject: Reset font size without using menus

By accidentally pressing and/or holding one or more keys on my PC, I seem to have shrunk the font size which I need to reset.

When I try to use OPTIONS GENERAL the screen will not scroll down to the FONT setting

Could you please tell me how to reset font size without using the menus?

I am using the latest version of Firefox (112.02 32-bit) with Windows 10 but am being blocked from certain websites by the Cloudflare security app because it says that my browser is out-of-date. This was particularly embarassing when I was trying to buy tickets for a concert recently and was unable to access the venue's online payment system.

It may be that Cloudflare is confused because I occasionly use an older version of Firefox (52.9.0 32-bit) with an earlier version of Windows. How can this issue be resolved so that Cloudflare does not block legimate access to websites when I am using the most up-to-date version of Firefox?
