I hope this is the right place (I've chosen Accounts).

When I ask a question, e.g. this, on the right hand side there's a "Subscribe to feed" option with a feed link of https://support.mozilla.org/en-US/questions/1492818/feed

When I insert that into my RSS reader, e.g. Feedbro on Firefox, the link isn't accepted.

How does this Subscribe to feed work? (Image attached.)

Thanks!

Hello.

Re: Bookmark/Edit Bookmark... right click context menu spaces

How can I reduce the spaces for the context menu for Bookmark/Edit Bookmark... A bookmark right click menus are reduced already, however the Edit Bookmark... opens up then right click the menus (Undo, Redo, etc)are, I think, in the original wider spaces. Currently my userChrome.css is as follow to reduce spaces, /* Tighten up drop-down/context/popup menu spacing */ menupopup:not(.in-menulist) > menuitem, menupopup:not(.in-menulist) > menu {padding-block: 0px !important; min-height: 0pix !important;}

root {--arrowpanel-menuitem-margin: 0px 8px !important; --arrowpanel-menuitem-padding: 0px 8px !important;}

Regards,

Dear firefox,

I accidentally changed the google account email to an email for the website sonicwire (I was using temp mail). I was hopeful because of the password manager but you cant revert the username back to previous saves without going to edit the files (witch doesn't work for me btw) but is there another way through an extension?

For whatever reason, when I open certain websites in Firefox, it shows the prices in UK currency including VAT, but when I open the same websites in Chrome, they show up in US currency. The Windows region setting and the VPN connection is the exact same for both. The difference is the browser.

Is there some setting in Firefox that makes it think I am in the UK, and if so, how do I change that?

Years ago i had an issue with this useless browser. I had the setting to start where i was left of, so the taps should reopen as they were but every time it was starting from the beginning also with different windows than what i choose from settings. i have deleted the browser and now i have downloaded it again but i face the same issue. You cannot talk with a real agent so this is the worst browser ever. I am only try to use it because i have to, otherwise i would NEVER EVER use it again after all this issues. As i cannot get help from Firefox as they don't even have support team... Can anyone please help me with that. Thank you

Hi everyone.

This could be related to the corrupted file I had that was solved here: https://support.mozilla.org/en-US/questions/1492585

I mean something else could have been corrupted. I've been getting the following error on a website:

> "The site at [url] has experienced a network protocol violation that cannot be repaired. > > "The page you are trying to view cannot be shown because an error in the data transmission was detected."

I thought it was a website issue. But it worked fine in Edge.

I tried the Ctrl+F5 but nothing changed (also tested the website in private browsing in both FF and Edge; still works fine in Edge).

Thanks!

Edit: I launched the factory settings profile from about:profiles (last used years ago when I moved my main profile from an older PC) as a test and the issue persists.

Any help to fix this would be much appreciated

I have tried restarting both firefox and my computer, disabled all extensions and started firefox in safe mode. When I try to right click on a firefox window from the taskbar it just disappears.

I have my computer connected to my TV so often when I open it up some windows will be on my TV which is behind my desk so its a pain to move them back without this function.
