Diễn đàn hỗ trợ Firefox

I have been observing an issue since a month that- a few YouTube videos are not being played when it is opened in Firefox, whereas the same videos are working fine in other browsers. The videos are getting loaded by the time, and the captions are also visible but no picture is visible and no sound. First I thought, may be it's an issue of the AdBlocker (uBlock Origin) that is enabled in my browser, so I disabled it and tried again, but still the same problem.

One of the videos I'm having issue with- https://www.youtube.com/watch?v=W_lzMUGgeYg

Please help, it's too irritating :(

Suddenly when I try to go on Youtube, I get messages that I'm blocking ads. I'm on a Mac-mini using X El Capitan V10.11.6, which is the highest I can upgrade to. I'm using Firefox Browser 78.15 (64-bit) and info shows it's up to date. My old Safari browser still will work with Youtube, but Foxfire is my go-to browser.

Hello. Whenever that blue broader on the new tab appears, it doesn't let me type on my keyboard and doesn't let me switch to a different tab and open my folder on the desktop whenever I press my keyboard. Does anyone know how to fix this problem?

screenshot is attached.

while I was running a game on steam (Apex legends), and Firefox on my other screen, I was using too much memory, so the steam game and Firefox crashed. The game works fine, but Firefox won't load anything, Except for settings and the "About:" pages. When I try to visit a website it does not even attempt to load it, but the website does show up in my history. I've restarted Firefox, I have reinstalled Firefox, I have restarted my computer, I've cleared my cookies and cache history, but no websites will load and it will only run properly in troubleshooting mode. Oddly enough it won't load any websites but while I'm in the add-on manager I can download extensions.

How do I keep Firefox from losing the internet connection just cause I don't want to close all the tabs I've had open the past week or so? I've tried clearing the cookies, and then reloading my open tabs, but it ends up losing the connection, just the browser itself. Other browser still works. Completely closing all tabs and restarting Firefox gets it working again, but dare I reload the previous session again, open all the tabs (acts like it's going to work), but then loses connection.

I have a local app on my machine hosted on port 80 using a non-encrypted HTTP connection. Tonight I upgraded my Firefox browser to version 108 and I cannot for the life of me figure out how to allow this connection. Before the upgrade, it worked perfectly fine, after the upgrade it tells me it was unable to connect but in the address bar I see that it's trying to connect to HTTPS Even though the bookmark is HTTP. If I remove the s from the address bar, it still refuses to connect. The chromium-based browser on my computer will connect to this site without any trouble, as will the legacy browser. This seems to be a problem introduced in version 108 and I have no way around it. Has anybody else experienced this problem? I don't want to write a sloppy bug report so I'll probably just wait for someone important to have this problem and the next release will probably have it fixed, but it's pretty annoying having to open up my chromium based browser in order to access this one local URL.

I used to have Firefox update itself using automatic updates, and occasionally I would manually trigger an update by checking the HELP>ABOUT menu. For some time now, I am getting an error message inside the ABOUT pop-up window. The current message is "Unable to check for updates due to internal error".

I've un-installed and re-installed several times. It doesn't happen on other computers I own where updates work just fine.

I tried searching, but couldn't find anything relevant

Any ideas how to fix this?

Thanks !

Recently have been unable to access the USPS Website from any of my Firefox Browsers. Firefox displays the following Message:

You do not have permission to access this page If you have found this page in error, please contact support Reference:10593116689666961403465577003670526342620034968299102359

Every time I do something Google-related in my Firefox browser the tab crashes. It does the same whether it is the search engine, Google drive, G-mail, etc... I already ensured my browser is updated, to no avail.

Thank you!

For months, I've experienced the Bookmarks menu collapsing (Bookmarks Toolbar, Bookmarks Menu, and Other Bookmarks headings appear but all bookmarks are just gone) and locking up (those headings cannot be opened and closed).

I have finally noticed that this happens when I am using Windows File Explorer to drag and drop files into my Google Drive opened with an entirely separate Google Chrome browser running concurrently with Firefox.

To be clear, I have Google Chrome and Explorer at the top of my desktop, with Firefox running behind them. When I drag a file from Windows Explorer over to the Google Chrome browser, the side bookmarks window in Firefox goes haywire. Close and reopening the bookmarks menu brings it back, but the issue remains.
