Diễn đàn hỗ trợ Firefox

Today Firefox stopped altogether and dimmed the entire window and popped up a "Try the Firefox VPN" message. I use Firefox specifically to get away from disruptive, intrusive violations like that. This needs to be removed immediately and never ever happen again. It's completely antithetical to the core values of Firefox.

Furthermore, several users have reported it breaking their browsing. See this Reddit thread:

This affected me on Windows 10 running Firefox 113.0.2 64 bit.

When I scroll down to look at recent posts on Facebook groups I follow all but the top one has suddenly lost its date/time – I just get a blank where the details would usually be and have to hover over to reveal the details. The silly thing is that this only happens when I sign in and it doesn’t happen when I use chrome – although I prefer using Firefox, not least because the bookmarks sidebar is better. I have tried getting rid of all extensions and running in troubleshoot mode but without success. Any help/advice would be appreciated (as long as it is not about football!)

Received this message thismorning while using my Ledger device:-

Something went wrong-U2F browser support is needed for Ledger. Please use Chrome, Opera or Firefox with a U2F extension. Also make sure you're on a HTTPS connection.

I can not access for days my bank account at truist.com. It shows it is loading but never does. I CAN access from any other browser want to use! Truist says it is a Firefox browser issue.

Hi

I have a problem when I play a video I get pixels I've seen that other users have the same problem I tried some of the solutions like disabled hardware acceleration and change some stuff on about:config (media.windows-media-foundation.use-nv12-format. double-click it and change its value to false) and use safe mode but nothing seems to work

What can I do?

This just started happening today When I try to sign in to my comcast email account from my desktop shortcut I get Peer's Certification has been revoked Error Code sec_error_revoked_certificate if I go to my bookmarks I can sign on????? My wife has a seperate sign in on windows 10 and the same thing is now happening to her, never happened before today

I've asked this question a long time ago, and received no answers. I resorted to resetting it every time, however a new problem has come about, forcing me to ask again.

Whenever I open my browser, my tabs have reset themselves to default width. I prefer them at a wider width, so I navigate to about:config and edit the browser.tabs.tabMinWidth to 100. I have to do this every time.

However, for some reason doing this now also hides/removes tab close buttons on each tab, which is problematic to my style of browsing.

I had an userCSS file, but even after removing it as a test, the problem persists. If it matters, my style of browsing has me keep two windows open at any given time. I did try to change it with only one window open, but the change did not stick.

Only tab-specific add-ons I have are FoxyTab and a tab suspender.

Any help is appreciated, be it making sure the tab close buttons do not disappear, or be it making sure the tabs remain at minimum of 100 width.
