Diễn đàn hỗ trợ Firefox

I am currently using Windows 11 and Firefox 145.0.2 on my desktop computer. Firefox is set as my default browser. Since the latest Firefox upgrade, the "Downsize/Minimize/Exit" toolbar does not appear upon opening and the only way I can close the program is to go to File<Exit, but I still have no way to downsize to share my screen with other applications. I sometimes have to open and close the program a couple of times before the Minimize toolbar appears. I already tried Firefox "Refresh" but the issue is still happening. </p>

Some websites won't load at all while other are very slow to load but some will load just fine, example Crunchyroll (screenshot attached) won't load at all its just spinning loading icon and a white page but if I try it in a different browser it works just fine, but with Youtube it will load but is choppy and low quality videos and same thing as before I load it in a different browser and no problems. I have tried every possible solution I can find from clearing cookies and cache to refreshing Firefox even scanned for malware and virus nothing has worked please help me figure out what is happening and why it's only with Firefox that I am having this problem and its not hardware can play online just fine and download games from steam perfectly fine.

Since I updated to Firefox 141.02 I have not been able to play videos on Paramount+ or Netflix. I get an error on the top that says the Widevine plugin has crashed on both streaming services. I have checked that the plugin is on and there are no updates. I am on Ubuntu 24.04. Video on YouTube plays as normal

I'm using the latest Firefox. All of a sudden as of this morning, Firefox cannot not load Facebook or Twitter. I can open YouTube and YouTube videos appear but will not play (just a spinning wheel when I try to play). The Amazon landing page is scrambled with code. (see image attached)

I use Ghostery ad blocker but the issue persists when Ghostery is paused. I can use Safari without issue. Can anyone offer any insights?

Restore previous session, in history, is an important setting. It has now disappeared completely as an option even though restore windows and tabs is ticked. Need to go deeper than the superficial help .

Hi, I unchecked something in my settings and I don't know what I did to cause when I right click to copy something there is no copy and a lot of the rest of the options are no longer there as well. Can you tell me what to do to repair this? It doesn't give me the option to take a screen shot either or I would show you what's left in that popup box. It only give me "Ask an AI chatbot" and the "translate".

Have a nice day, Tom

I just transferred my data from an old computer with Windows 10 and now have Windows 11 on my new computer with a new version of firefox as my browser. How do I restore my bookmarks?

I have lost my tabs after the recent update. They used to show all tab groups in toolbar icon as mentioned here (https://support.mozilla.org/en-US/kb/tab-groups) in manage tabs section. Only the groups that were open are retained, the groups which were closed are lost. They contained important tabs which I haven't bookmarked. I didn't see any policy of removal of inactive tab groups after certain time, any help would be really appreciated. I use the desktop app on Linux.
