Diễn đàn hỗ trợ Firefox

Over the past three weeks, since I updated my Firefox version to 148.0.2 (aarch64), a black or white rectangle appears at the top of all websites and prevents me from accessing some links on those sites.

I refreshed and cleared the cache, and it worked for a while, but then it appeared again on every single website.

It makes it unusable that, for the first time in 15 years, I might have to switch to another browser if I can't solve it.

In the attached picture, you can see that the place line covers the top of the site and cuts off the Firefox logo and the links above.

Any solution is welcome

My computer ran into an error and restarted and I lost my entire browsing history, bookmarks, extensions, etc. Now I have nothing saved and the only browsing history my computer is showing is when I briefly opened microsoft edge. I regularly used duckduckgo, so most of my data is gone. Is there anything that can be done or is it just gone.

Starting at 148 if a user is using Firefox and attempts to log into our MS RDP Application server using HTML, they can log in, but when they select an application, they get stuck at the loading screen with no progression. If they download the RDP file direct it works fine. It's only when using the HTML RDP website with Firefox.

Things we've tried

• We verified it began with 148.0.
• We've tested on multiple devices across multiple networks with multiple users.
• We've tried fresh installs and we've tried without any add-ons.
• We do have Duo securing that server, but I tested a user under bypass and it went right through.
• All other browsers work fine.

When I go to my Firefox browser on my desktop, I have to sign every time to google. I never had to do that until recently. I don't have to do it on my Edge browser or on my Iphone.

I messed up somewhere.

I am use a Phomemo Thermal Label Printer for labels and packing slips. The print preview shows the whole page, but prints only a partial page and small print. Tried all setting but no difference.. See photos

My son tried to voicemail me on Messenger but it said this browser does not support voicecalling. I have used this in the past, still on Firefox. I used to get note that a call was coming ans option to connect or discard. Now there is no option to connect. What can I do to get this service back?

This has started a few days ago. I'm running Firefox Desktop on Windows 11. Browsing is perfectly normal, until I try to watch a video in full screen mode. It plays normally for a few seconds and then my whole system freezes, with no response to any action except for hard reset. This has never happened to me before, and all other browsers I try do not demonstrate the same problem. Is there any solution other than changing browser permanently?

I cannot login into Kick.com, is it because am on Windows 10? If i use any other browser, it works fine no problems!! (the error it gives me is attached)

Здравствуйте. Не хватает гибкая настройка главной вкладки с моими сохраненными сайтами, а именно отключение "посещаемые сайты", чтобы их не пришлось каждый раз "удалять из истории" или "скрывать" из главного, ведь для меня это лишний мусор. Возможно ли добавить такую настройку?

Спасибо за внимание! Прошу извинить, что пишу на своём родном языке, так удобнее выразить свою мысль поточнее.

I get the message: We're Sorry Firfox had a problem and crashed. We'll try to restore your tabs and windows. To help us diagnose and fix this problem, you can send us a crash report. I sent the crash report multiple times.

I added a screenshot of my MacBook Air info.
