According to my settings, Firefox should clear the cache completely. Bur it is never fully cleared, there are always about. 9.3 MB left at the temporary data. It should be 0 MB. Even clearing the cache "manually" does not clear it completely. HOW CAN I CLEAR MY CACHE COMPLETELY? (Firefox / Windows 11)

See two attached Screenshots

So I had Mozilla account with Syncing Enabled before I reinstall windows (I had only Zen browser on my pc), and after reinstalling windows I downloaded Zen and got in my account, but after pressing syncing there is no passwords, no history, no bookmarks, literally no data that I had before, does that mean I lost all my data?

the top bar in the browser is so small it is hard to read and i find it difficult to access the icons. increasing the value of "layout.css.devPixelsPerPx" increased the browser text but did not affect the top bar. Is their another approach or is their a magnifier the will work. Thanks.

Just updated Firefox desktop (Win 10 with ESU) to 140.10.0ESR and now every site I try to access gives

Secure Connection Failed An error occurred during a connection to www.google.com. PR_CONNECT_RESET_ERROR Error code: PR_CONNECT_RESET_ERROR

Sites were all working fine literally right before. No other changes at all. Have restarted a few times. Have disabled antivirus and adblocker extensions. Same problem including at google.com and even firefox. Note on the About Mozilla Firefox window says " Failed to check for updates". Also cannot even use the links there to go to What's new or Firefox help etc. (Gives Secure Connection Failed error). No proxy server. Have tried turning anti virus completely off. Just a combined modem/router -- basically vanilla.

Firefox is my primary browser so this is extremely disruptive. I am using Edge to access sites and post this.. though curiously enough I noticed it gave some error when checking for updates. Do not want to do anything there or will lose complete access.

Any suggestions .. or how to go back to a previous version, if necessary. Need a workable connection to file taxes next week so this is important. Thank you.

Firefox doesn’t spell‑check in Copilot because Copilot uses a modern custom text editor that Firefox doesn’t recognize as a normal typing area. Since Firefox never turns its spell‑checker on in this kind of editor, nothing actually fails, so there’s no error code or message. The spell‑checker engine simply never activates. For this to work, Firefox would need to update its spell‑checker so it can handle newer web‑based editors instead of only traditional text boxes.

What do I do to solve this - I get this when I 'try' to game in Facebok: "Sorry, your browser does not support this feature. Please use a different browser and try again."

My passwords have been randomly disappearing from my PC. My android has the passwords intact but it will not sync in either direction. I have followed every instruction that I can find with no success.

On a couple of occasions, a successful sync has happened randomly a couple of days later.

On this occasion no syncing so far. (two days)

I am feeling that Firefox is becoming somewhat unstable, which is a shame as I have been using the browser since Noah was a lad.

Any ideas?
