I-Firefox Isithangami Sokwesekwa

On my Macbook Air M1, Firefox's UI and default scaling is perfect on my Retina display, but if I move the window to my external Philips 1080P monitor, some - but not all - interface elements are very over-sized, which makes Firefox unuseable on any external monitor I connect. (I have tested this with multiple other monitors)

This is my Mac Monterey. My Windows 10 is in Safe Mode With Networking. The last update will not download. That version is 125.0.3. What's available under Windows updates does not download either. Now I am running my antivirus on my Windows to see if it runs clean. I do not know why I cannot apply these updates.

I have enabled my new Theme but it keeps defaulting back to my old Theme. I have tried closing Firefox and opening new tabs. Opening a new tab also changes it back to the default theme. I have sent an image of the old theme. The new theme is Aurora Australis. And the second image shows this Theme enabled. What gives? Carl

When I click on "Bookmark current tab," the small bookmark window opens as usual. But if I then click on "save," nothing happens. The bookmark does not get saved anywhere and the window does not close. Likewise, if I click on "cancel," nothing happens and the window also stays open. Only if I click somewhere outside of the bookmark window does the bookmark get saved and the window close. This has happened only in the current and previous version of Firefox. How can I fix this?

Sorry to have this same issue again, knowing full well it can happen after finding this some years ago (https://support.mozilla.org/en-US/questions/1319823), I tried to carefully connect two older PC devices back to firefox sync, however on one I managed to enable sync before disconnecting my profile (it seemed as if reconnecting sync temporarily was the only way to disconnect a profile from firefox's UI - I should have been more careful and removed the profile from the filesystem level): at which point I polluted the sync server.

I've noticed that `about:sync` has an option under bookmarks/engine actions 'wipe bookmarks', which sounds exactly what I need, and if I watch what happens once pressed it does the right thing and repopulates the sever with the 'correct' PC's bookmark set (when run from that PC), however it also says 'other devices will act like a reset', which i'm finding NOT to be the case: eventually one of my other device repollutes the server with bad bookmarks which propogate.

I'm thinking the culprits are my phones, If I wipe and do a sync on a phone, my phone's bookmarks stay polluted. If i'm right about that, I think my question is: can I wipe my profile (or preferably only my bookmarks) from my phones' Firefox without having to entirely uninstall/reinstall (or do you have any other advice for not re-polluting the server from some already-polluted device's bookmarks?

thanks in advance
