Diễn đàn hỗ trợ Firefox

I just installed Win 11 with a fresh Firefox install (113.0 / 64-bit). I use a single video screen.

When I double-click on the FF icon, no Firefox browser window appears. However, in task manager, I can see that Firefox has opened and using a lot of memory.

I also put the FF icon in my "Pin to Taskbar" area. After I start FF, normally I would see the pinned icon highlighted (program open), but the taskbar FF icon does not show FF as active.

What have I destroyed this time?

I have AdBLockPlus (free version) installed and have not had any issues until today. Firefox did some updates and now the Add-In is no longer working. I have checked that it is specifically turned on for the websites I'm visiting and I've tried turning it off and back on to no avail.

Hi

Well Firefox did it again. I had tabs on the bottom where I wanted them and they broke this again in the update I just got.

Any idea how to move them back down to the bottom? This is the userchrome.css coding I was using that worked fine before the update

Hello. Wanna report that i noticed strange border while in fullscreen mode while watching a video. The same things happens even if you go fullscreen mode on browser (not a video). Yesterday was fine. System 7, 64bit, Mozilla update 113.0

Hello, Today, when I first open Mozilla I noticed that I have problems with fullscreen mode. When I use fullscreen (f.g. on YouTube, but it's with all clips in other pages too) I can see white borders (on the left, right and at the bottom). I checked on other browser (Chroma) and I don't have this problem there. Can this problem be connected with new update? Or something just broke and I should re-install?

Hi, I disabled several options in about:config, and a feature previously disappeared. When I pressed the scroll button in the diamond, it opened a tag and automatically navigated to it. Also, when there was a previously open page, and I open any bookmark (tags), the selected page opens in a new window, I want it. Please help me.

Some pages were crashing before, now that I have updated to 113, happens on almost any page. Same problem in troubleshooting mode, so not an extension, plug-in, etc. Attached troubleshooting info.

I've just installed Firefox 113.0 and my tab bar is now above the toolbar and bookmarks bar. Up until 112, the tab bar was below the bookmarks bar. I have no changed anything in UserChrome and in fact that file is still dated 2020. I've searched but haven't found an explanation. Anyone know what changed or is this just a bug? Thanks

I just upgraded firefox to v 113 64 bit with windows 7 ultimate. Now when I watch youtube in fullscreen there's a border around the screen. i don't use picture in picture and it isn't on yet the border won't go away no matter what I do. Please fix this or i will use another browser. i will include a screenshot from youtube in fullscreen mode look at it.

In youtube videos, creators will say "click the link above" and point and often there will be links on screen during a video for related content, aka annotations. They simply don't exist in firefox. I can't click or even see them. I opened YT in chrome and the annotations all pop up and are clickable. Annotations are turned on I've cleared cookies to no avail. Please advise.

Lately when opening something in full screen it shows the background as sort of a frame around it. The dark blue at the top is the header background colour I use. It's really annoying. I can't tell if it happened in a recent update as those happen automatically. But it's just been the past few days. I use 113.0 (64) right now. I'm sending a screenshot of how it looks.

After updating from version 112 to 113 - performance has dropped dramatically.

In the beginning the performance after the update was faster than before. But as of tonight and today it's much worse than it was before the update.

I noticed that the browser started using more CPU than usual. Ryzen 7 5800X3D.

Cleaned cache already two times - didn't help. Tried Safe Mode - didn't help.

The link colors are suddenly incorrect. Normally the links are blue and the visited links are purple, but now they are pastel light-blue and pastel pink. This problem is not in Edge or Chrome. I am using Firefox 113.0.1

I have tried - rebooting windows - windows shutdown, wait, restart - changing the firefox website appearance and themes (auto, dark, light) Still no solution. Any ideas? Thanks.

On some websites text selected by dragging the mouse appears with light gray background on white.

What I did to check for possible local problems:

• Hardware (AMD Radeon HD 6670 connected by HDMI to Acer-QG241Y)

Used monitor color-test (https://www.eizo.de/monitortest/) and fiddeled arround with all color-gradients: all smooth.

• switched off anything I could think of in Firefox (13.0 64 Bit Win 10 (updated today))

Extensions, plugins, themes

So I suspect there is no problem at all with my hardware or software. Just an bad choice in the color design of the websites I visit.

If so, what can I do? Is there any chance to provide some remedy locally? Installing a theme (I don't know anything about themes) or provide a local CCS to override the CSS of the website? (Would not know how to connect such skript to Fx and what to "instructions" to specify inside. But as I understand the idea of CCS correctly, this is an option that it was built for.)
