So I just switched OS on my desktop, and had to log into Firefox all over again for the first time in a bit, and it turns out that for some reason my saved passwords arent synchronising with my whats saved on my phone? In the past my experience have been that if I ask firefox to save my password on one device it remembers it on all my devices. Is this not the case? Is there something I need to do to manually synchronise?

I am okay with just being sent the download for win 10 or 11 because I'm not sure why its even giving me such a out dated version. (side note I do want to mention that it is amazing Firefox has the option and goal to let you install a different operating system instead of locking you out to just a Linux version and i do want to say i don't use Firefox as my main browser but a back up from now on because of the accessibility)

I have used 4 rows of site icons on my home page for years. (Linux FF since 2013, various distros.)

After an update, they became tiny AND so close to the bottom that a zoom of even 110 percent was unacceptable. (I prefer 100 percent.) 100 cut off the labels at the bottom.

I deleted my search bar from homepage yesterday, and had already deleted top stories and weather years ago.

Several searches over the last few days have done nothing.

Screenshot of zoom at 110 and straight 100.

Firefox is disconnecting my account every time i restart the browser. I've made sure it's not set to clear data when restarting. I found a support forum post for mac where they weren't installing it and were running it from the dmg, but i'm using the firefox that was installed during cachy installation, which firefox gives /usr/bin/firefox, when runnign it from terminal (or anywhere) the command in btop is /usr/lib/firefox/firefox. its really frustrating because i lose my session data, have to log back in again, have to redownload all my extensions, ahve to reconfigure all my extensions every time the browser restarts

I'm on CachyOS on COSMIC de with a btrfs file system. I've tried uninstalling and reinstalling firefox. I've tried making a new profile. I really don't want to use a different browser, but this isn't functional.

I have [[created a backup file|https://support.mozilla.org/en-US/kb/firefox-backup#w_protect-your-sensitive-data-with-a-password]] today with the latest available Firefox and switched to a new OS. Sadly, the backup file somehow seems to have gotten damaged, even if Firefox still recognizes when I'm inputting the wrong password. On Ubuntu, where I originally created the backup and where I tested it again after things weren't working out, Firefox tells me that there is an issue with the file and that I should try a different one (which I don't have). On CachyOS, which I'm currently testing out, restoring the backup never finishes and Firefox doesn't exit cleanly. In hindsight I obviously should 1) have tested the backup immediately, 2) not have wiped my laptop prematurely, and 3) have backed up the folders manually, but I haven't. Now the question: is there some way to extract the account details from the .html file? I don't care much about the rest, but restoring the accounts in some other fashion is gonna be a lot of work.

The master password should either pop up right away, or not pop up at all until sensitive information will be accessed. It sometimes pops up on a delay, which is annoying, as I may already be typing something into the URL bar only to find that the second half of what I typed is now into the master password entry.

During this time of delay, I am apparently still able to access web browser functionality. This creates inconsistent protection and makes me question what the master password is protecting. I thought I would only have to enter it before autofill, but entering it at startup implies it protects the entire functionality of the web browser, not just passwords.

But, if it protects the entire functionality of the web browser, then why does it pop up after a delay, which is sometimes long enough for me to have already started to use the browser, meaning that, if my operating system account is shared but my browser is private, someone already could've made a social media post in my name in the time before they are required to enter the master password, if they are fast enough.

Really think about your intention and please establish or make clear your philosophy with this confusing and annoying design choice. Is there a way to either stop the delay, or to make it only pop up when accessing autofill functionality, or to make the browser entirely inaccessible until the pop-up grabs focus?
